What kind of water does not wash away soap. Why does soap wash off badly? Water features
If you receive water from municipal system water supply, then your water is regularly monitored and must comply with accepted standards. Another thing is that while the water reaches your tap through the pipeline network, it may be subject to secondary pollution. If you have doubts about the quality of your water, you can contact either the Sanitary and Epidemiological Station at the place of residence, or one of the independent certified laboratories, or reputable water treatment companies.
By nature, our skin is enough for water! Soap is useful in such cases. Hands: Wash several times a day. After the toilet before every meal when they come outside. Prevents bacterial infections! Body: Showering or bathing is not necessary daily, but only if you are really dirty or sweaty. Armpits, buttocks and genital area should be washed daily with soap!
Face: Wash with soap only once a day, preferably in the evening. Who washes too much dries out the skin and makes them more susceptible to infection. Basically enough plain soap. Those with sensitive skin should choose a product with little or no perfume. Presumably, "repackaging" the soap has not proven effective. If you have dry skin, you should wipe yourself after washing with a moisturizing lotion. Separate soaps for different parts bodies are not needed.
Of course, for water obtained from an individual or collective well, analysis is simply mandatory.
Moreover, it is important that water for analysis must be taken directly from your tap, and not somewhere from a common riser or from a water tower. After all, you are interested in the analysis of your water.
How to collect water for analysis?
For many applications, water hardness does not play a significant role (for example, for extinguishing fires, watering the garden, cleaning streets and sidewalks). But in some cases, rigidity can create problems. When taking a bath, washing dishes, doing laundry, washing a car, hard water is much less effective than soft water. And that's why:
- When using soft water, 2 times less is consumed detergents;
- Hard water, interacting with soap, forms "soap slags" that are not washed off with water and leave unsympathetic stains on dishes and plumbing surfaces;
- "Soap slags" are also not washed off the surface of human skin, clogging pores and covering every hair on the body, which can cause rashes, irritation, itching.
- When water is heated, the hardness salts contained in it crystallize, falling out in the form of scale. Scale is the cause of 90% of failures in water heating equipment. Therefore, water heated in boilers, boilers, etc., is subject to an order of magnitude more stringent requirements for hardness;
- In many industrial processes, hardness salts can enter into chemical reaction, forming undesirable intermediates.
- Soap is made from fat.
- It is boiled with lye and thus broken down into its main components.
- Fatty acids combine with alkali to form a new substance: soap.
The industry offers several thousand soaps. All of them are based on similar recipes. Additional ingredients such as milk, honey or olive oil are mainly used for marketing and affect the smell and feel when used. The cleaning effect is not improved.
After washing with soft water, the feeling of "soapiness" remains. What is the reason for this and is it harmful?
This phenomenon is well known to residents of the northern regions, where the water is traditionally softer. Indeed, when washing with soft water, the subjective impression of soap "indelibility" remains, the skin remains slippery, as if soapy. This phenomenon is connected with the fact that after the removal of hardness salts from the water, "soap slags" are no longer formed, which destroy the thinnest fatty film covering the surface of healthy skin and protecting it from harmful external influences. It is this film that gives a feeling of slipperiness. And this is not only not harmful, but on the contrary, it is extremely useful. After all, it is not for nothing that cosmetologists recommend washing your face and washing your hair with rain or melt (and therefore very soft) water. Unfortunately, we are more accustomed to washing the body and hair "squeaky" in hard water, and then trying to restore the broken protective film with creams and lotions.
Are disinfectant soaps helpful? They can also usually kill important good bacteria and irritate the skin, so are not needed. Shower gel and shampoo in one - is it good? Shower gel and shampoo combinations are practical and just as good as individual products, as both are liquid soap with similar ingredients. Combined products save a lot of bottles in the bathroom. A combination of shampoo and hair conditioner is not necessary as most people only need to wash once or twice a week, but wash their hair more often.
How to use soap correctly? Pay attention to the mixture: a lot of water, a little soap! Always wash the lather thoroughly, otherwise it tightens the skin. Especially in regions with very calcareous water, otherwise an oily film easily remains on the skin. Volker Steindraus, Prof.
How does freezing affect the purity of water and its chemical composition?
First, a little digression into the theory.
Ice has a crystalline structure built from water molecules. Foreign impurities, including those dissolved in water in the form of salts, have no place in this crystal lattice when water freezes. Therefore, as it forms, the crystal lattice, as it were, "displaces" impurities. If this process takes place in a container, for example, in an ice mold, then as a result all impurities are concentrated in one place (for example, in the middle, if the volume of water was cooled evenly from all sides or at the bottom of the container, if cooling came from the surface), and they are surrounded by clear ice of pure water.
It sounds like: "What is a cloudy smell?" Well, that's a very simple answer: it's just that the clouds don't smell at all. Except for squeezing advertisers, of course. To delve deeper into this topic, Dr. Rosa Ortega, president of the Andalusian branch of the Spanish Academy of Dermatology and Venereology and professor of dermatology at the Faculty of Medicine of the University of Granada, responded to the claims of young French women. Letizia opened her journal to explain her everyday experiences, shaped by a more modest-than-usual lifestyle.
If you had to examine the resulting ice cubes, then you saw a cloudy "cloud" inside the cube - these are impurities. The nature of the formation of this "cloud" is quite simple. In a place where salts are concentrated, water cannot freeze completely, forming a transparent crystalline structure (this property of salts is used when pouring streets into ice). Moreover, the more polluted water, the greater this turbid component. The cleaner - the more transparent shell. So, reverse osmosis water obtained on membrane plants produces almost perfectly transparent ice. Therefore, all over the world, such systems are installed in front of ice generators.
Videos about recycling, self-esteem, hygiene and nutrition are the order of the day, but the formula worked for her. A year ago, this young woman had an epiphany: it was better to live in a simple form. Despite the fact that he lived in Marseille, where the famous soap of the same name was, he said that he did not trust the composition of the product, so he decided to abandon it. In addition, she states that to avoid dry skin - she lives in an area where the water is very hot - it is enough to spread a little olive oil. In short, water seems to be enough to keep the skin hygienic and healthy.
Thanks to the phenomenon described above, the inhabitants of the Far North theoretically have a method of purification by freezing water. You can either chop off the outer transparent shell and then melt it, or melt the entire block, but not completely. As soon as the ice melts to a cloudy center, it must be thrown away (if you melt all the ice, you will get exactly the same water as the original one - its chemical composition will not change).
However, according to Dr. Ortega, there are places where the water is very alkaline, has a lot of salts and causes dry and itchy skin, which is prevented by using soaps without detergents or oil baths and then moisturizer. In this sense, the water itself, although washes, will be short to counteract its own effects of dryness, since it contains negative elements for the body. Therefore, the use of alternative products would be vital to maintain 100% healthy skin.
From the gel of a lifetime, Letizia went to Ghassoul, Morocco, made in Morocco, which seems to be very good for the skin. But, since the product was expensive and begged that it was a mess, he decided to skip it and be left alone with the water. With this new technology, which she kept a secret at first, Letizia discovered that neither she nor the people around her perceived bad body odor. In addition, he directly linked this effect to his diet: he claims that the absence of meat and packaged foods reduces strong odors.
In this way, you can get almost perfect clean water. By the way, ecologists consider the melt water of ancient glaciers to be the safest for humans.
Another question is how difficult it all will be. Indeed, for water with a rather high salinity, the efficiency of this procedure may also turn out to be low - the clean layer is too thin. There is only one way to deal with this - very fast and deep freezing. In this case, the area of salt concentration will occupy a much smaller volume. The case for a small cryogenic installation. If it is at hand, then go ahead and get to work. If not, then in this way you can and can get some water - for example, for cosmetic procedures. But for drinking needs and cooking, you will need quite a lot of water, and initially not of the worst quality, we will tactfully keep silent about the time spent.
From Granada, the dermatologist claims that sweat itself doesn't smell, but it's the bacteria on the outside that "contaminate" the sweat glands, causing that characteristic bad smell. Although there are foods that affect the natural smell of each of them, such as onions, garlic or spices.
Nothing else If it does not depilate - especially in the genital area - a glove also helps. This part of the body is also particularly sensitive to soap, and it ensures that it is perfectly capable of self-cleaning without any hiccups. Water is also a solution to attending services because paper is unhygienic.
The solution to the problem throughout the civilized world is either the use of membrane methods based on reverse osmosis(water is the same as melted water), or two-, three-stage purification (sedimentary filter, activated carbon, microfiltration). In the latter case, the water is not desalinated, but with a good initial quality, this is enough.
The latter, present in areas such as delicate areas such as the armpits, groin, and genital area, should be washed daily with soap and water as they are more susceptible to external agents that aggravate this bad smell. He says that when he was young, and if he used soap, they would always appear to him. Acne occurs mostly in youth.
Also for use very fatty soaps that are not suitable for the type of skin you have, says the dermatologist. "Perhaps the young woman's problem was her own youth or the use of inappropriate soap." These other substances, which are fat-soluble and even greasy, need the use of soap and water to dissolve and be removed from the body, says Dr.
If you've ever searched the Internet for information about hard water or water softening systems, you've probably noticed that the web is full of conflicting information on the subject: some websites advocate soft water and water softeners, usually because they sell them. while others blame soft water for harm to human health and the environment. Any smart consumer will notice that most of the arguments for soft water are made to directly or indirectly sell their product.
In fact, for those who are concerned about soaps with detergents in their composition, syndicate soaps are used to treat sensitive, dehydrated, dry and itchy skins. At the time, it was more of a cult between the pinnacles and beauty experts than a generalized variant to clear the skin among the rest of mortals.
However, over the course of the past year, virtually every beauty brand has launched their version of water purification, catapulting this product to an Olympus of great favorites for many women, but also sowing a few doubts about its use, among devotees and amateurs alike. We speak with two experts. to list the reasons that exist for using micellar water. Non-irritating Avoid contact with running water also avoids possible irritation. In addition, as the director of the Boris and Saki center Christina Vigo explained to us, “it is a water formulated very softly and with great skin tolerance.”
So we wanted to offer our unbiased look at soft water, water softeners, and salt-free water conditioners to stop the spread of unfounded myths and other so-called "facts".
One popular misconception is that ion exchange is not the only way to soften water. In fact, water softening, in the usual sense of the term, is possible only through the replacement of calcium / magnesium ions with sodium ions. There are also systems that "soften" water without salt, but these systems are only water conditioners, not softeners. Such systems do not remove the minerals that cause hardness, but rather trap them and form them into insoluble crystalline particles that cannot linger on pipes or fixtures, and thus cannot create the internal contaminants that are the hallmark of hard water. . It is also worth noting some new technologies such as capacitive deionization, but they have their drawbacks, so for real water softening, that is, reducing its hardness, a water softener is still the best approach.
You don't need anything else. Yes, if you choose the right one, you won't need to use more cleaning products. "Micellar water has a set of molecules that attract dirt, so it's enough to eliminate any makeup or impurities," explains Cristina Vigo.
It can also be used for oily skin. Oily skin implies a combination of such concepts: if you have oily skin, you need to use a cleansing soap or water gel. It can replace tonic. This is the great slogan by which many commercial waters are known. And yes, if micellar water has tinting properties, we can skip this step. Micellar water completes the three stages: cleanses, tones and moisturizes. This requires additional hydration, explains Cristina Vigo.
Some sources suggest using a reverse osmosis system to soften and purify water in a cottage. Technically, this is possible, although impractical - water, before being passed through a reverse osmosis system, will first have to be treated with anti-scale to prevent clogging of the membrane. In addition, using reverse osmosis to remove minerals will be much more wasteful than simply using a water softener, since the operation of a reverse osmosis system results in approximately a liter of waste water for every liter of treated water.
It leaves no greasy residue. This is another of its advantages: it does not leave the skin tight and leaves no greasy residue. In addition, it facilitates the application and penetration of subsequent treatment products. Serves for eyes and lips. If your eye and lip makeup is waterproof, things get more complicated. But if the makeup is not waterproof, cleansing waters can be used, if formulated, on sensitive areas such as the eye, eyes, and lips. “The absence of alcohol and parabens from some creams shows high tolerance for all types of sensitive areas,” explains Aurora Barranger.
One of the cons attributed to water softeners is the fact that they add sodium to the water, which is harmful to human health. This argument has some basis: as already mentioned, water softening occurs due to the replacement of calcium / magnesium ions with sodium ions, so softened water naturally contains more sodium than before treatment. However, the amount of salt added at the same time to any, even the hardest water, is still significantly below the established recommendations.
It is easy to use. Just apply it with a cotton ball without dragging, with small touches and no subsequent removal. “As we said, it also hydrates,” explains the director of Boris and Saki. It can be used after going to the gym or taking sunbathing. It frees the skin from impurities such as sweat or sea water when it is refreshing. If you then use the thermal water to protect the skin and remove the skin barrier, much better.
Organization of dishes and removal of excess dirt
However, boring work is inevitable. But, as one should do it, nothing is better than consciously using water. The first step is to organize your dishes so that the clean parts are cleaned first so you can leave the dirtiest in the sink, and as the wash water goes down the sink, the dirtiest dirt softens. Good example- leave the pot inside the sink while you wash the cutlery. Also, remove large dirt by hand and without water.
However, it is worth noting that the additional sodium contained in softened water comes from sewage into lakes and oceans, and small amounts of sodium that are safe for you can accumulate and ultimately have a negative impact on wildlife and environment. In some areas where municipal water is reused for agricultural and recreational purposes, water softeners have even been banned due to the belief that they are responsible for increased chloride levels in reclaimed wastewater.
Instead of filling the detergent detergent, separate a small bowl of water and put some detergent into it, or mix the soap inside. Thus, it is possible to save the product about which in question, in addition to saving water - since there will be no excess soap in the parts.
When the wash starts, turn on the faucet as low as possible. Excess water is not a guarantee of clean dishwasher and you can still get your clothes wet. Turning off the faucet when no part wears off is not essential. Another tip is to wash multiple items that can be washed together, such as cutlery and pots.
What about changing the taste of water? Some people swear that softened water tastes better, while others swear that hard water tastes better, and even suggest that drinking softened water can deprive the body of essential minerals. The number of minerals found in drinking water in most places, is so small that it is negligible in the context of daily nutritional requirements. The decision to drink hard or soft water is unlikely to have any effect on your health and is usually more of a personal or aesthetic nature than a strong medical justification.
Such aesthetic preferences are usually the main factor in the decision to soften hard water for bathing, although in this case, soft water has specific advantages due to its chemical composition. In soft water, without calcium and magnesium ions, the soap lathers more easily and stays on the skin, rather than being instantly washed off with water. With soft water, you can cut your detergent and bleach consumption by 50% or more.
Soft water prolongs the life of clothes because it does not break down fabric fibers like hard water, which is why all commercial laundries use soft water. Soft water saves energy by removing scale from water heaters and dramatically extends the life of fixtures and appliances, saving thousands of dollars over the cost of a softener.
So soft water is better than hard water? The answer depends almost entirely on the hardness of your water.
Hardness 1-100mg/l (calcium carbonate)
If the hardness of your water is in the range of 1-100mg/l, it is considered "relatively soft" water. Water hardness is determined by the sum of calcium and magnesium (usually coming from limestone rocks in ground water) that are in the water. natural waters may contain minerals ranging from almost zero to many hundreds of milligrams per litre. Water with a content of more than 100-150 mg / l is considered hard enough for possible softening, therefore softening is not necessary for this type of water.
At levels 100-200mg/l water softening or salt-free water conditioning is an excellent money-saving home improvement by reducing white coating on fixtures and surfaces, extending the life of plumbing, plumbing and appliances and improving the condition of clothing, hair and skin. Commercial establishments such as laundries, hospitals and hotels use water softening to reduce costs and extend the life of equipment and laundry. Most of the modern soaps and detergents on the market contain special chemicals and salts to overcome the mineral barrier and increase the effectiveness of the soap in hard water. By softening hard water, you are less exposed to these chemicals and can reduce soap and detergent usage by up to 80%. Your clothes will wash better and your hair and skin will be softer without the use of conditioners or lotions.
The total hardness is determined by the sum of the concentration of calcium and magnesium ions, expressed as calcium carbonate. Hardness is measured in milligrams of calcium carbonate contained in 1 liter of water.
The term "hardness" was originally used to refer to the ability of water to create soap suds. The “harder” the water, the worse natural soap dissolves in it.
Hardness 200-700mg/l
Water with a hardness index of 200-700 mg/l is considered "very hard". Normally, water conditioners without salt are not recommended for water of this type of hardness.
Hardness over 700mg/l
Water that contains more than 700mg of minerals per liter is considered "extremely hard". This type of water will definitely have a serious effect on your home appliances, plumbing and appliances. Water softening is strongly recommended for such water. Water of this hardness requires a powerful water softening system of a special type.
