The first ingredient in cosmetics is water, the second ingredient is oil, and the rest are functional additives such as emulsifier, thickener, humectant, chelating agent and preservative, which shows the importance of water in cosmetics.
There are many kinds of water in cosmetics:
1, the most commonly used is deionized water (mostly used in ordinary cosmetics):
Deionizing equipment is used to purify and remove the plasma of calcium, magnesium, sodium and zinc, so as to prevent these components in water from reacting with other additives to form complexes, which will affect the effect.
2. Deep seawater (many cosmetics advertisements on the market have deep seawater, which cannot be specifically verified, but if deep seawater is really used, it is theoretically better for the skin):
About two thousand years ago, icebergs in the Arctic and glaciers in Alaska began to melt, and the dissolved ice water gradually settled on the seabed because it could not be dissolved in warm seawater with high salinity immediately. According to the research results, it is found that deep ocean water has at least the following four main characteristics:
A: Low temperature stability:
Not exposed to sunlight, unlike the temperature of surface water in the ocean, the temperature of deep water is constant all the year round, at 8 ~ 10℃.
B: rich in ingredients and stable;
Deep-sea water contains more than 90 kinds of inorganic salts and minerals (including trace elements), which once gave birth to life and were indispensable for plant growth and human health. In addition to its rich content, water flows in the deep layer of the "dark layer" for a long time, without photosynthesis and external influence, so the inorganic salts and minerals (including trace elements) contained in it are very stable and are low-oxygen water.
C: easily absorbed by the human body;
Under the strong water pressure of hundreds of millions of years in the deep sea, the water mass in the deep water is obviously smaller than that on the land. Much like the molecular binding angle of water and blood in human body. Therefore, the water mass is easily absorbed by the human body.
D: aseptic purity
The deep water in the "dark layer" of the ocean is far away from the influence of modern human civilization, is not polluted by chemicals and germs on land and in the atmosphere, and does not have the conditions to produce bacteria such as pathogens. Therefore, deep ocean water is very clean and sterile natural water, and it is "green" water.
3. Spring water (representative brands are Yang Ya and la roche-posay, both named after place names and famous for their unique mountain spring water and hot spring water).
Spring water provides an ideal water source for human beings. Spring water is filtered underground, and some trace elements in geology will also be integrated into the spring water, so the chemical composition of spring water varies from place to place, and its functions are also different, such as physiotherapy spring and drinking spring. The total number of springs in China can reach more than 100,000, which are widely distributed and rich in types, and there are countless famous springs everywhere. Most people in China have the idea of worshipping foreign things and obsessing foreign things, and they will import brand myths.
4. Negative ion water (negative ion water has been developed for some years, but it has been used in cosmetics for nearly two years, and the representative brand is Famanrou).
Many domestic manufacturers of water purifiers and water-based cups use negative ion water as a gimmick. In fact, they just used the principle of electrolytic water. Water electrolysis will produce hydrogen and oxygen, so the hydrogen content in water will increase, which is also commonly known as hydrogen-rich water, which will not produce negative ion water and water will not become alkaline water. This experiment actually exists in junior high school chemistry, which is very simple. Just fooling the people.
Real negative ion water must have three characteristics at the same time, both of which are indispensable:
Answer: Negative ion water must be alkaline water, and alkaline water is not necessarily negative ion water. According to Lewis' theory of acid-base electrons in 1923, substances that can provide electrons or electron pairs are alkaline; Substances that can accept electrons or electron pairs are acidic. Therefore, negative ion water has extra negative electrons, which can give electrons, so it must be alkaline. This alkalinity is different from chemical alkalinity. The alkalinity we usually know is the theory of acid-base ionization. It is acidic that can ionize H+, and alkaline that can ionize OH-.
B: Negative ion water must be small molecular water, but small molecular water is not necessarily negative ion water. Similarly, because all negative ions have the same negative potential and the same polarity repel each other, water molecules repel each other, thus maintaining the activity of small molecules for a long time.
C: Negative ion water must contain excess negative charge. Negative ion water can not be obtained by electrifying and electrolyzing water, and there can be no so-called positive ion water. A normal atom or molecule has no characteristics, because atoms are composed of protons, neutrons and outer electrons. Protons are positively charged in the nucleus. If an atom loses or gains more protons, it becomes other elements, which is what we usually call nuclear upheaval and nuclear fission. The outer electrons revolve around the nucleus, and the farther away from the nucleus, the lower the energy state. If the outer electrons gain energy from the outside, they will be easily stimulated to escape. The escaped electrons are unstable and will be captured by other substances. For example, after lightning weather, the outer electrons of some substances gain lightning energy and are stimulated to escape and become free electrons. This free electron is captured by oxygen and becomes an oxygen negative ion. If it is captured by water, it becomes negative ion water.
Anion water is widely used, and now it is a new subject. The anion water now found has the following functions in conditioning skin health:
A: Nutrient transport
Clinical transdermal experiments show that the negative ion reduced water can not only be absorbed by the skin itself, but also be used as a transport carrier to transport the nutrients needed by the skin to the basal layer. Because it has good compatibility with cells, it will not cause harm to human body. In addition, a large number of minerals (calcium, magnesium, sodium, potassium, etc. ) obtained in electrolytic negative ion reduction water, which is easily absorbed by skin in ionic state.
B: reducibility
Free radicals (also known as reactive oxygen species) have always been the source of cell oxidation, aging and diseases in human body. Because anion reduced water contains a lot of active negative electrons, anion reduced water is the smallest, strongest and most superior antioxidant in the universe, so anion reduced water is naturally the best antioxidant component.
Free radicals are the source of all diseases and aging. Negative ions can effectively eliminate free radicals in the body and restore the healthy state of cells, which has a good effect on regulating skin health, delaying aging and fixing youth. Cosmetics developed with negative ion water are not specially designed to solve skin problems such as hormone face, acne and dermatitis. Instead, restore the health of skin cells and increase the skin's own resistance, thus solving these problems by the way.
C: antibacterial and anti-inflammatory
The pH value of the water reduced by negative ions is12 0.5, which is far from the breeding domain of microorganisms. And a large number of negative charges attached to it can penetrate the cell membrane of negative bacteria, thus killing negative bacteria. Experiments show that Escherichia coli, Pseudomonas aeruginosa, Salmonella, Staphylococcus aureus, Vibrio enteritidis, Leigh virus, methicillin-resistant Staphylococcus aureus, Candida albicans, Herpes 2 virus and Acne Bacillus can be killed after 60 seconds in the negative ion reducing water environment.
If it is really negative ion water, then the developed cosmetics do not need to add any preservatives.
From the ingredient list of cosmetics, we can see which ingredients are preservatives, such as ethyl hexylglycerol, phenoxyethanol, methyl p-hydroxybenzoate and methyl isothiazolinone. (These preservatives were not found in cosmetic additives in 1995, so those containing such preservatives can also promote products without additives, but there is no problem in using ordinary skin, but it may cause secondary damage to babies with fragile skin such as hormone face, sensitive muscles, pregnant women and children).
To sum up, parents can understand the quintessence of Chinese culture: Farman Rou Muscle Bottom Purification Series products. If its cosmetics claim that the product uses negative ion water, it must have the above characteristics. If satisfied, parents can use it with confidence. If you are not satisfied, you are conceptual. Be careful. After all, the baby with hormone face, sensitive muscles and various skin problems can't afford to be hurt. Besides, I wish you a speedy recovery. Most of the above contents are summarized for myself, I hope they are useful to you.
