Everyone wants to look more radiant. In recent years, women have paid more and more attention to skin care, and then there have been more whitening and anti-aging cosmetics on the market. With the consumer's emphasis on cosmetic ingredients and the emphasis of various brands on the promotion of ingredients, various cosmetic additives have become well-known, such as hyaluronic acid, nicotinamide, HEPES and so on. What is the role of HEPES as a common cosmetic ingredient in cosmetics?
HEPES is a zwitterionic buffer, which belongs to good's buffer, PH buffer range is 6.8-8.2. HEPES buffer is commonly used in research work on organelles and highly volatile, pH-sensitive proteins and enzymes, and it is also used in biochemical diagnostic kits, DNA/RNA extraction kits, and PCR diagnostic kits. Because 4-hydroxyethylpiperazine ethanesulfonic acid (HEPES) has the characteristics of safety and mildness, the EWG green level certification is level 1 (0-2 is the green security level). HEPES's EWG certifications are all classified as green and meet international standards, meeting people's demand for "safe and natural" cosmetic ingredients.
The role of HEPES in cosmetics is shown in the following aspects:
1. HEPES is called the new generation PH regulator, which has the effect of maintaining the stability of cosmetic quality.
The pH value of the HEPES adjustment solution is 6.8 to 8.2, which is particularly suitable for pH adjustment under physiological conditions. The reason why HEPES plays an important role in cosmetics is that it can balance its stronger acidic counterparts in cosmetic solutions. nature.
2. Penetrating agent to promote the absorption of active ingredients in cosmetics.
It is well known that cosmetics can only exert their skincare and beautifying effects if they are fully absorbed. On the contrary, it may cause "skin oxidation" due to excess epidermal nutrition, causing premature skin aging and skin infections. Adding a penetration enhancer to cosmetics can just promote the transdermal absorption of various functional components.
HEPES is such a safe and efficient cosmetic penetration enhancer, which can promote the absorption of nutrients in cosmetics without entering the subcutaneous tissue and circulation in the human body. It not only overcomes the problem of the stimulation of the penetration enhancer on the skin in the prior art, but also has a fast effect and high penetration efficiency. The effects of various cosmetics such as Garnier Blemish Essence and Armani Light Key Toner may be significantly due to the addition of HEPES to these skin care products.
3. HEPES can soften keratin and promote cell renewal.
HEPES is a weakly acidic system. It resembles macromolecule fruit acid and has the effect of softening keratin and promoting cell metabolism. It is widely used in whitening and light spots (Vichy Magic Water, L'Oreal Centella Asiatica Micro Essence), anti-aging skin care products (Lancome black bottle, YSL night queen essence), by reacting with other ingredients, then it It can remove old keratinocytes, effectively promote the renewal of basal cells, achieve smooth, soft skin, and brighten the complexion.
HEPES is used in finished products to fully play a role in improving rough skin texture and alleviating enlarged pores. HEPES also has the effects of synergistic sun protection, strengthening the skin barrier and other effects. It is very popular with sensitive muscles, and it is the skin rejuvenating cream of Ke Yan's.
In addition to HEPES, tromethamine (Tris) can also be used as a cosmetic additive. Desheng has 15 years of R&D and production experience in blood collection tube additives, Good’s buffers, chemiluminescent reagents, etc. It only provides high-quality products to customers for the long-term development company, and can provide high-quality raw materials HEPES, TRIS, etc.
