Every biological system has a well-known buffer system to maintain the acid-base balance within a specific pH range. Our lives depend on the function of the buffer system. A buffer system is a solution that resists changes in pH when acid or alkali is added. Different buffers have different ability and efficacy for skin replacement. The high-quality Good's Buffers produced by Desheng are usually used in cosmetics, such as toners, essences, lotions, eye creams and facial masks, etc., according to your application. Here are 4 biological buffers commonly used in cosmetics.
1) HEPES (4-hydroxyethylpiperazine ethanesulfonic acid)
CAS Number: 7365-45-9
Useful pH range: 6.8-8.2
The main purpose
1. Acidity regulator, or pH control agent.
2. An effective concentration of HEPES can provide an exfoliating effect.
3. Promote the transdermal absorption of various functional ingredients in cosmetics.
2) TRIS (Tris(hydroxymethylaminomethane))
CAS number: 77-86-1
Useful pH range: 7.2-9.0
use:
1. Non-ionic surfactants-amines
2. Acidity regulator or pH control agent.
3. Excellent cleaning ability and emulsifying ability.
3) BIS-TRIS (Trimethylol) Methylamino Propane)
CAS Number: 5625-37-6
Useful pH range: 6.1-7.5
The main purpose
1. Non-ionic surfactants-amines
2. Acidity regulator, or pH control agent.
3. Excellent decontamination, dispersion, emulsification and antistatic ability.
4) Glycylglycine buffer (G-132)
CAS Number: 7365-44-8
Useful pH range: 7.5-8.9
The main purpose:
1. Adjust the pH range of the solution
2. Condition the skin, reduce pores and prevent skin aging.
3. Excellent emulsification, dispersion, antistatic, wetting, penetration, and decontamination capabilities
Precautions
External factors, water and detergents may reduce the local buffering capacity, because the elution of buffer chemicals leads to increased pH and irritant contact dermatitis. Inflammatory diseases, including atopic dermatitis, psoriasis, and acne vulgaris, increase in pH and decrease buffering capacity. For the treatment of skin diseases and aging skin, emollients with a pH value slightly higher than the average normal pH value and with appropriate buffering capacity should be used first.
Desheng is a professional manufacturer of biological buffers. There are many cooperative manufacturers in the skin care industry. In addition to the two biological buffers Hepes and Tris, it also produces many other models such as Mops, Taps, Pipes, Caps, and the core product tris buffer. Known for its ability to maintain the original color of emulsions and excellent odor suppression capabilities, it is widely used in cosmetics such as skin care lotions, sunscreens, eye makeup products, nail polish, etc. It can maintain the functional effectiveness of active substances and is a skin care product The industry's trusted choice.
