Introduction
The twenty first century is a time when information became the foundation on which all spheres of human life are based. Therefore, each person must be sure that the information he owns is reliable and will not bring spiritual and physical damage to him and others. The flow of information reaches us from everywhere, but the main source is the media. And often even an educated and sophisticated person cannot determine whether they are trying to deceive us by using advertising tricks or only slightly exaggerate the merits of the goods and services offered. Advertising has become an integral part of our lives. Sometimes it really helps to navigate the variety of goods and services, and sometimes it promises just "miracles." Due to the active advertising policy of manufacturers, today almost every family uses special means for washing dishes. So, scientists estimate that the Russian family of 4 people washes about 5 tons of dirty dishes every year! The first MCs appeared more than 5,000 years ago in the Middle East. But their role in our lives has not changed yet. MS is currently used to remove various types of dirt: stains on clothes, rust, dirty dishes, etc.
We will continue to coordinate the work of the Polish Pharmacopoeia Commission, the Commission on Medicinal Products and the Interdepartmental Commission on the Production and Use of Drugs. We will continue to expand the activities of the documentation and scientific information section. The work will be carried out with the aim of improving academic qualifications and obtaining higher education and advanced degrees by the staff of the Institute. In the field of science, we will consider the development of new analytical methods in the field of problems of the Polish Academy of Sciences and the Ministry of Health.
In terms of its composition, dishwashing detergents are close to shampoos and shower gels. That is, to hygiene products. And they have special security requirements. All this is good, however, dishwashing detergents are listed as household chemicals. This means that they do not need a hygienic certificate guaranteeing safety. The requirements for the toilet cleaner, which are the same for dishes. Manufacturers may subject their products to safety testing, but voluntarily. Chemists acknowledge that this certificate only guarantees that at the time of use you will not be poisoned or ruin your skin. But what happens over time in the body, in which residues of detergent constantly fall, such studies have not been carried out.
Undoubtedly, the aforementioned issues do not cover issues that life itself often highlights, and the development of which often requires extensive and thorough research. The plan of activities of the Institute of Medicines for the next decade covers the most important problems that will be gradually implemented by the management of the Institute of Medicines to the extent possible.
The next decade is characterized by a certain stability of the organizational structure. New units are not created so quickly, but there is a change and expansion of existing plants and divisions due to the expansion of the scope of work. Laboratories are changing to establishments that employ more workers, while other existing ones expand and expand.
With the constant increase in the number of new chemicals entering the circulation, actual problem is to study them in order to obtain information about the potential hazard of substances and the development of preventive measures involving the prevention of adverse effects on the human body and the environment. Among the complex of environmental factors that are subject to hygienic control, household chemical goods (TBH) deserve special attention due to their mass production and use, the variety of components that make up the recipes, as well as possible direct effects on the human body. As you know, after use, all chemicals enter the environment and adversely affect it, but we don’t think about it. Therefore, we decided to devote our work to household chemicals and, having studied the composition of MC for dishes, determine how safe their use is.
These are also years of staff training, a degree. Young masters become doctors, elders do habilitations, and also receive the title of professor. In the course of the current work many dissertations and dissertations are being born. The Institute actively participates in research conducted within the framework of centrally planned government and departmental issues. Some topics, as well as test questions, are a source of inspiration for problem solving and research that will serve the future scientific development of workers.
We believe that our work is very relevant today. We can not do without the MC, but their use often harms our world. To understand how to deal with the harm done to us by the MS, we must first learn more about them than is reported in the advertisement. We decided to conduct a study in our school in order to identify the means that are in the greatest demand and to analyze what justifies the choice of participants in our study. To say yes or no to the MS case is every person’s business, but if you follow certain rules, then the health risk will be minimal.
The faculty of the Institute has many academic advantages. Kubikovsky supported and assisted in the appearance of several foreign internships, received scholarships, attended conventions and congresses. Travel and travel, originally limited to neighboring countries, gradually began to change for a longer stay at renowned research centers in Europe and the United States.
People from these trips returned abundantly, not only by conducting specific research works, but also by making personal contacts, getting to know other countries, and meeting other cultures. This expansion of view had a positive effect on work in the country, helping not only to solve current problems, but also allowed to study life in the world.
Practical significance The work consists in the fact that the obtained information on the results of the research work can be used to educate the population of the village about the harm of certain detergents, about the negative effect of SMS on human health, on enhancing the corrosion of metals from which sanitary engineering is made.
Personal ambitions were awakened to get a degree. The institute had a good atmosphere for research. The times in the country were still difficult, there was still no money, the Institute had very difficult living conditions, fought for the modern apparatus, but people very diligently make the Institute also creating the basis for the internal enrichment of their own lives.
The long-term director of the Kubikovsky Institute of Medicines contributed to the creation of such a climate. In the 1960s, 24 doctors were received. Borkowski was a good spirit of these works. Then these actions continued prof. It was a time when many of the Institute’s staff participated in the study. This route was followed by another. Some of the doctoral students were habilitation, and some were awarded the title of professor. Irena Wilczyńska-Voytulevich, doc.
purpose works: to investigate the physicochemical properties of detergents, to investigate the effect of detergents on the corrosion of metals from which sanitary engineering is made.
Tasks :
1. To study the literature on this issue;
2. Identify the most commonly used home-made detergent brands for dishes;
Kubikovsky retired, became director of the Institute of Medicines, continued his efforts to improve the skills of employees. In the 1970s, over a dozen people received their Ph.D. degrees. The seventies were a period of prof. At the same time, he continued his vision of the Institute, which he had occupied during the previous 8 years as deputy director for core business. These years, although economically difficult, are characterized by the development of the Institute; Both the scope of audit work and research work have been expanded, and, as mentioned above, there has been a further scientific development of the staff.
3. Examine the composition, data detergents for dishes using their labels.
4. Investigate the physicochemical properties of detergents;
5. To consider the effect of detergents on metal objects (nail).
Object of study : liquid dishwashing detergent.
Subject of study: properties and safety of using detergents for dishes, metal corrosion.
At this time, scholarships and study opportunities were opened abroad. They also went to the Medicines Institute, and many of their employees went to shorter or shorter periods of stay at that time. They enriched themselves with knowledge that enhanced the level and expanded the scope of the Institute’s activities, and at the same time often provided the basis for new qualifications and degrees. In the seventies, a dozen or so earned a Ph.D. We also train people from other countries, for example, in the Pharmacology Department under the supervision and promotion of prof.
Hypothesis: if you have complete information on the composition and properties of detergents, then You can save human health, prevent damage to plumbing, made of iron.
In accordance with the objectives of the study, methods of systematization of theoretical material, research methods and methods of observation, generalization of accumulated material were used.
Denmark received 2 doctors from Egypt. During these years, many leaders of the Institute received a degree of habilitation. Undoubtedly, this fruitful decade had already begun in the sixties, which is a great achievement of the two previous directors: the director, prof. Kubikovski, Deputy Director - prof. In the following decades, the fruits of previous efforts were outlined.
In the sixties, there was only one such trip - doc. Dr. Jan Venulet, Head of the Department of Pharmacology in Damascus. Undoubtedly, such situations have increased the prestige of the Institute outside. There were also favorable conditions for active work in international scientific federations.
Chapter 1. General information about dishwashing detergents
1.1 Dishwashing detergents and their properties
Special dishwashers first appeared in the 1950s. Dishwashing detergents are available in liquid or gel form. Gel-like agents are considered more effective than liquid ones.
The main properties of the tool is its detergency. A big plus means is its ability to effectively deal with oil and grease in cold water, this is achieved through the selection of the optimal surfactant composition.
Regardless of how he traveled, the Institute permeates its daily work and expands its field of activity. The Center for the Study of Drug Abuse also marked the beginning of the existing Center for Pharmacoepidemiology. Regarding registration issues, the Institute has developed its organizational activities in the field of preclinical and clinical drug evaluation. During these years, various spheres of life in the country were controlled centrally. Topics and problems of the ministry and government were also formulated in the field of health.
Another important feature of the dishwashing liquid is its gentle effect on the skin of the hands. It is worth noting that the statements of manufacturers that the pH level of their products is 5.5, in no way can guarantee the absence of irritation, especially in people prone to allergies. Therefore, during washing dishes skin needs protection. The tool should contain softening components and you should not forget that hands can be protected from the harmful effects of the tool with the help of ordinary rubber gloves.
The Institute of Medicines included these studies in basic and applied research. The main problem was the problem of drug control. Increased requirements for assessing the quality of medicines led to the development of new methods. In the field of chemistry developed an instrumental analysis. New drug safety tests have been developed. There is also a new specialization in the field of microbiology: the study of drug pollution and the evaluation of their microbiological purity.
As part of the microbiological study, disinfectants, preservatives and the evaluation of their antimicrobial activity were included. The work was carried out in close connection with the international teams dealing with these issues. The scope of analysis of medical materials has also expanded, including an assessment of new plastic materials and dental materials. The company was involved in research in the framework of the Central Development Program, dedicated to the issues of evaluation methods of products intended for contact with body tissues.
Much about the dishwashing detergent can tell its composition.
1.2 Composition dishwashing detergent
The basis of the detergent are surfactants. It is they who determine its washing ability.
Surfactants are divided into two types: ionic and non-ionic (non-ionic).
The principal difference is that nonionic surfactants are not subject to electrolytic dissociation, i.e. they do not break up in water into positively and negatively charged ions; when interacting with water, ionic surfactants decompose into ions, some of which have adsorption (surface) activity, while others (counterions) are adsorption inactive.
Similarly, the scope of work of the department of isotopic drugs was developed in assessing the quality of radiopharmaceuticals used in Polish medicine, which allowed him to join the government program: “Fighting Cancer Diseases”.
The field of activity of the Institute has also significantly changed in terms of vitamins. The initiator of this work was prof. This method allowed us to conduct research on the contribution of vitamins to cancer and to investigate the mutagenicity of certain drugs. These works were also included in the government program: “Fighting cancer”, as a result of which a large number of graduate students of the Vitamin Department appeared.
Ionic surfactants are called anionic, if the surface-active ions carry a negative charge, and cationic, if the positively charged ions are surface-active. Some surfactants, depending on the conditions in which they are used, exhibit either anionic or cationic properties; therefore, they are called amphoteric or ampholytic. Anionic surfactants - organic acids and their salts. Cationic - bases, usually amines, and their salts. In the global production of surfactants, most of the anionic substances.
The Department of Pharmacology was widely involved in the development of government and departmental problems. Works organized in the seventies by the then head of the department, prof. The director of the institute was Danysh. These were problems of the mechanisms of action and the fate of drugs in the system, as well as closely related issues of controlling side problems and undesirable effects of drugs. These studies were part of the Institute’s efforts to tackle the problems of the government: “Fighting Cancer” and “Preventing and Fighting Cardiovascular Diseases”.
In the study of the medicinal mechanism, the results of the Department in the field of membrane transport of drugs and targeted pharmacotherapy are of particular interest. The 70s at the Institute of Medicine were economically difficult, but still characterized by the further development of the Institute and its staff. The new face of the Institute was created at a time when its foundations became a solid foundation for an ever-expanding business, and then the scientific development of personnel and the beginning of contacts with the world.
Synthetic detergents necessarily contain a number of excipients that improve their detergency. The composition of the detergent compositions sometimes include alkaline salts of weak inorganic acids (sodium carbonate and sodium bicarbonate, sodium silicates, phosphates of different composition), neutral salts (sodium chloride), salts of peroxide acids with whitening and disinfectant properties (perborate and sodium percarbonate). It is these chemicals that enter into chemical reactions with the metals from which plumbing is made, and under the action of these substances and corrosion of metals occurs. Corrosion causes billions in losses annually, and the resolution of this problem is an important task. The main damage caused by corrosion, is not in the loss of the metal itself, but in the huge cost of products destroyed by corrosion. That is why the annual losses from it in industrialized countries are so great.
An important role is played by organic components of surfactants: carboxymethylcellulose, which prevents the redeposition of contaminants from the washing solution on the washed surface, and the so-called hydrotropes, which increase the solubility and accelerate the dissolution of surfactants in water.
Some detergents contain enzymes that remove insoluble protein contaminants, organic bactericides, foam stabilizers.
In many detergents add aromatic substances (fragrances), designed to eliminate odors and give the washed surface a fresh aroma. True, the smell of apple, lemon or, for example, wild berries does not mean the presence of extracts of the above mentioned fruits in this product.
Also in the composition of dishwashing detergents may include substances that mitigate the negative impact on the skin of the hands. The most common supplements are glycerin, silicone, and herbal extracts. Glycerin and silicone have a similar effect, they create a protective film on the skin that prevents it from drying out. At the same time, the surface film created by silicone can protect against the penetration of substances harmful to the skin contained in the detergent.
Herbal extracts soften the skin, have a calming effect, relieve irritation, which can be caused by individual components of surfactants (such action has, for example, milk "aloe vera"). But even with all the undoubted merits of these supplements, it is impossible to guarantee your skin complete safety.
Chapter 2. Diagnostics of detergents for dishes
Diagnostics of the use of dishwashing detergents.
In order to find out which of the funds are the most used, we interviewed students, teachers and school employees. 50 people took part in the survey.
Survey data shows that Fairy is the most popular medium. It is used by 19 people from the number of respondents, which is 38%. Next, in descending popularity, go: "AOC" - 11 people, 22%; “Myth” - 7 people, 14%; “SORTI” - 7 people, 14%; "Drop" - 6 people, 12%.
2.2. Composition, properties and features of the use of detergents.
For the study of the composition, properties, features of the use of detergents for dishes, labels of the products indicated when questioning users were studied. As a rule, no one reads the instructions for washing dishes, but this does not relieve the manufacturer from having to put this information on the label.
These studies are shown in table 1.

6. Precautions
In case of contact with eyes, rinse with water.
Keep out of the reach of children
Protect from sunlight. Keep away from heaters. Keep out of the reach of children. In case of contact with eyes, rinse with water.
Keep away from children, avoid contact with eyes.
These tables allow you to do the following findings:
With an equal volume of detergent, the price of funds is not the same.
“Fairy”, “AOC” can be attributed to more expensive means, “Myth”, “SORTI” and “Drop” are cheaper means.
The shelf life of all funds is almost the same.
The main component of MS are surfactants.
in addition to surfactants in the composition of detergents there are dyes, preservatives, perfume composition, but no labeling of these substances is indicated, which does not allow us to conclude that they are safe for humans.
The packages do not indicate the exact amount of product required for use. Only it says “put a small amount on a sponge or on dishes” or “drop a few drops ...”.
Virtually all means except "Fairy"Contain a warning:" Keep out of the reach of children "and describe the actions when the product gets into the eyes.
Much attention is paid on the MC label to advertising data: manufacturers indicate that all means effectively remove fat, not only in hot but also in cold water, are easily washed off with water, without leaving stains. On the label means "Fairy»Indicated that complies with the standard of the Russian Federation on washability from dishes.
2.3. Physico - chemical properties of dishwashing detergents.
Test 1: Study of the pH of the solution.
One of the requirements for the use of detergents for dishes is that they must have a neutral or slightly acidic pH value of the solution (pH = 5.5-7).
To determine the pH of the solution, we took a 0.1% solution of each agent, examined it with a device for determining the pH of solutions. The results of the experiment are shown in table 2. Conclusion: All remedies are pH neutral.

Experience 2 : Phosphates in dishwashing detergents .
The presence of phosphate additives in detergents leads to a significant increase in the toxic properties of surfactants. They penetrate the microvessels of the skin, are absorbed into the blood and spread through the body. This leads to a change in the physicochemical properties of the blood itself and impaired immunity.
0.1% solution of each agent was tested with silver nitrate. There was no yellow or white precipitation in the tubes. A yellow precipitate indicates the presence of phosphate ions in the samples (Ag 3 PO 4), a white precipitate indicates the presence of chloride ion (AgCl) in the samples. The results of the experiment are shown in table 2.
Conclusion: Phosphate additives in detergents are not detected.
2.4. Influence of detergent solutions for dishes on the course of processes
corrosion of iron objects.
When disposing, the used detergent solutions for dishes are in direct contact with metal sewage pipes, and when washed with metal dishes.
For the study, a 0.1% solution of each detergent was prepared and an iron nail 80 mm long was lowered into each. The experiment was carried out at room temperature. Tap water was used as a control sample. The experiment was conducted with three repetitions.
On the first day, rust appeared on the nails in the following media: “JSCS", "a drop Sorti". On the second day, a rust bloom appeared in a test tube with tap water and on a nail dipped in "Fairy» . In the “MYTH” tool, rust appeared in the test tube on the third day, while the nail remained clean. In the following days, the buildup of rust on the nails increased, and most quickly in the media: “Fairy"," JSC S", "a drop Sorti". Rust was deposited at the bottom of the tubes - a brown precipitate. By the end of the observation, the height of the sediment was different in test tubes: “AOS"- 10mm," Fairy"-7mm," a drop Sorti"- 9mm," MYTH "- 4mm," Drop "-9 mm, water - 3mm.
Conclusion: All investigated solutions of dishwashing detergents contribute to the corrosion of iron objects, and therefore have a negative effect on sewage pipes and metal dishes.
Final part
Findings:
The most popular among the population are the means: “Fairy”,
« AOS.
Labels of detergents contains a large amount of advertising promises,
but not complete information on the composition and labeling of ingredients, on the method of application.
All means are well soluble in water.
4. All funds are neutral.
5. Means do not contain harmful phosphate additives.
6. All investigated solutions of dishwashing detergents contribute to the corrosion of iron objects, and therefore have a negative effect on sewage pipes and metal dishes.
We want to advise you more responsibly to the choice of detergents and not to allow advertisements to deceive themselves. Do not forget that our children and grandchildren will live on this planet, and we must take care of their future and health. Also, do not forget that the use of certain detergents affects our environment. We also want to advise you, be careful with detergents and do not forget that they contain ingredients that can cause rashes, chemical burns, irritations and allergies. Always read the precautions written on the back of the package and keep detergents away from children.
We are aware that the consumption of detergents by people cannot be stopped, or even reduced. Moreover, with the increase in the population of our planet, the number and variety of detergents inevitably increases, which adversely affect not only humans, but also the environment.
We hope that in the course of progress safer detergents will be invented, which will be able to completely dissolve in water without forming harmful chemical compounds. The information obtained during the research work can be used in teaching a school course in chemistry, biology, ecology, during class hours, in conversations with pupils and parents, in elective classes in chemistry and ecology.

CONCLUSION: We do not deny the need for advertising and its important role in the life of a modern person, but we urge you to be very thoughtful and critical of everything that advertising companies bring down on us from the pages of newspapers, from television screens, from numerous posters. leaflets and brochures. Reading any ad, try to find out if its content does not contradict the laws or the concept of the natural sciences that we study in school.
