CAS7365-45-9 HEPES Buffer

Details:

In recent years, as consumers pay more attention to the ingredients of cosmetics and brands focus on ingredients, more and more cosmetic additives, such as hyaluronic acid, niacinamide, HEPES, etc., have come into the public eye. As a buffering agent, how does HEPES play a role in cosmetics

HEPES, Chinese name: hydroxyethylpiperazine ethanesulfonic acid, this product is a zwitterionic buffer, belongs to good's buffer, and is widely used in cell culture media, IVD kits and other fields. Because it can control a constant pH range for a long time and is non-toxic to cells, it is also used as a commonly used cosmetic additive.

The role of HEPES in cosmetics is manifested in the following aspects:
First of all, HEPES is called a new-generation PH regulator, which plays a role in maintaining the quality of cosmetics.
The pH range of HEPES adjustment solution is 6.8 to 8.2, which is especially suitable for pH adjustment under physiological conditions. Therefore, in cosmetic solutions, balancing the properties of its more acidic counterparts is the main role of HEPES in cosmetics. .

Secondly, the penetration enhancer promotes the absorption of effective ingredients in cosmetics. As we all know, only when cosmetics are fully absorbed can they have the effect of skin care and beautification. If the nutrients in cosmetics cannot be completely absorbed, it may cause "skin oxidation" due to excessive nutrition of the epidermis, leading to premature skin aging and skin infections. At this time it is the turn of the booster. Adding penetration enhancers to cosmetics can promote the transdermal absorption of various functional components.

HEPES is such a safe and efficient cosmetic penetration enhancer. It can promote the absorption of nutrients in cosmetics without entering the subcutaneous tissues and circulation in the human body. It not only overcomes the effect of penetration enhancers on the skin in the prior art. The stimulation is fast, and the effect is fast, and the efficiency of promoting penetration is high [1]. HEPES is added to various cosmetics such as Garnier Blemish Essence and Armani Light Key Toner. This may be one of the reasons why such skin care products are effective.

In addition, HEPES has the effect of softening cutin and promoting cell renewal. HEPES, a weak acid system, is similar to macromolecular fruit acid, which has the effect of softening cutin and promoting cell metabolism. It is widely used in whitening and lightening (Vichy Magic Water, L'Oreal Rejuvenating Centella Micro Essence), anti-aging skin care products (Lancome Black Bottle, YSL Night Queen Essence). It interacts with other ingredients and can be gently removed Old keratinocytes effectively promote the renewal of basal cells to achieve smooth, soft skin and brighten skin tone.

In addition to the application and function of HEPES in some cosmetics, it is also used in many water-based, emulsion creams, and cleansing cosmetics. Desheng is an established blood testing reagent company, which has in-depth research on chromogen substrates and biological buffers. The purity of the HEPES developed and produced by it: >99%, good water solubility, stable process, can ensure the appearance of the product is pure white crystalline powder, is a trustworthy company.
