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.

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
