Product Introduction
AEPD is a biochemical reagent with a molecular weight of 119.16, soluble in water. AEPD can be used as an additive in aqueous suspensions to improve the conductivity of suspensions, can be used as an alkalizing agent in hair forming compositions, can also be used as a component of polyurethane foam, and can also be used in inks.
Application of AEPD
In daily hair styling, curling and straightening of hair is usually based on the following two steps:
Step 1: The cysteine disulfide bond of hair keratin is opened by the action of a composition containing reducing ingredients (permanent forming composition). Reducing agents use compounds containing thiol functional groups.
Step 2: Use a fixative (i.e. a combination containing oxidizing components) to reclose the cysteine disulfide bond.
The first step of the cysteine disulfide opening reaction is carried out under pH 7.5-9 conditions. However, reducing agent compositions based on thiol functionalities can produce unpleasant odors. Therefore, it is necessary to add a large amount of fragrance to the product. By using thiolactic acid, the odor can be slightly reduced. However, compared to the widely used mercaptoacetic acid, the permanent deformation effect of thioglycolate is significantly weaker. Therefore, the CN116390709A patent provides a composition for permanent hair forming, which significantly improves the unpleasant odor during and after the hair forming process, and provides effective permanent hair forming performance.
The hair forming composition consists of four parts: reducing agent, alkalizing agent, fatty alcohol, and non-ionic surfactant,
The alkalizing agent can be composed of the following components: ammonia, ammonium carbamate, ammonium bicarbonate, monoethanolamine, diethanolamine, triethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-1-butanol, tris (hydroxymethyl) aminomethane, tris - (2-hydroxypropyl) amine, lysine, 2,2-aminodiethanol, aminourea (guanidine carbonate), tetrahydro-1,4-oxazine 2-Amino-5-guanidinic acid, 2-aminoethanesulfonic acid, N-methylethanolamine, isopropanolamine, diisopropylamine, triisopropanolamine, glucosamine, sodium hydroxide, potassium hydroxide, lithium hydroxide, magnesium hydroxide, other water-soluble physiological tolerant salts of organic and inorganic bases, as well as their mixtures;
