Hubei Xindesheng Material Technology Co., Ltd. is a professional manufacturer of biological buffer raw materials. The biological buffer produced by our company has stable properties and high purity, and can be used in common toners , essences, lotions, eye creams, facial creams and other skin care products. in products and cosmetics. The following introduces to you 3 buffers used in cosmetic raw materials, 3(-hydroxymethyl) aminomethane (Tris), 4-hydroxyethylpiperazineethanesulfonic acid (HEPES), bis(2-hydroxy Ethyl)iminotris(hydroxymethyl)methane (Bis-Tris).
3 (-hydroxymethyl) aminomethane (Tris)
3 (-hydroxymethyl) aminomethane (TRIS), also known as trometamol , is a zwitterionic biological buffer. Within the pH range of 7.2-9.0, TRIS has the best buffering capacity and can maintain the pH value of the solution at 4.75-5.75 for a period of time, and this pH value range is just suitable for human skin. Therefore, TRIS buffers are often used in emulsifiers, thickeners , moisturizers and other formulations to adjust and stabilize the acidity and alkalinity of the product. Because TRIS buffers reduce or suppress product odor, they can be used in the formulation of sunscreens, leave-on nail polish, eye makeup, and lotions.
HEPES
Like TRIS, 4-hydroxyethylpiperazineethanesulfonic acid (HEPES) is also a zwitterionic buffer, and its applicable pH value range is 6.8-8.2. HEPES buffers are often used to adjust the PH value of cosmetic products and stabilize it in a weakly acidic state suitable for human skin. It does not affect the efficacy of other ingredients and even promotes the transdermal absorption of its functional ingredients. The concentration of the buffer will affect its buffering capacity. A certain concentration of HEPES can be used in exfoliating products.
BIS-TRIS
Bis(2-hydroxyethyl)iminotris(hydroxymethyl)methane (Bis-Tris) is a weakly acidic buffer containing trace amounts of ionized hydrogen ions. In cosmetic raw materials, it changes the pH value of the product. Adjust and stabilize in a suitable acidic state. Bis-tris buffer has excellent decontamination, dispersion, emulsification, antistatic capabilities, and high UV absorption capabilities. Therefore, it is often used to replace maleic acid
TRIS, HEPES, BIS- produced by our company in some sunscreens. TRIS is a white crystal powder with excellent properties and a purity of over 99%. The professional R&D team can customize indicators according to customer needs. Welcome to consult.
