L-Valine is a white, crystalline amino acid powder that is essential for the body and is used in protein biosynthesis.

It is a branched-chain amino acid, which means the body can't produce it and it must be obtained through diet. It's a non-polar aliphatic amino acid that contains an amino group, an carboxylic acid group, and an isopropyl side chain.

Carbomer
1.Carbomer (carbomer) is a high molecular weight polymer of acrylic acid bonded with pentaerythritol allyl ether or allyl sucrose. Calculated according to the dry product, the carboxylic acid group (-COOH) should be 56Chemicalbook.0%ï½?68.0%. Carbomer is a very important rheology modifier. The glue combined with water is acidic. The neutralized carbomer is an excellent gel matrix, which is important for thickening and suspension.
2.Carbomer (Carbomer) is a pentaerythritol and other resin that is linked with deformation. It is a very important and fantastic
rheological modulated chemistry book section. The neutralized carbomer is an excellent spring limit. , There are important
processes such as thickening and suspension, simple, good stability, and a wide range of deep, cream, and medium processes

Application:
Carbomer is used for topical formulations and suitable for preparation of gels, creams and coupling agent. Carbomer and
cross-linked acrylic resin as well as series products of these cross-linked polyacrylic acid are widely used at present and are often used in topical lotion, cream and gel. In a neutral environment, Carbomer system is an excellent gel matrix with crystal appearance and nice sense of touch, so Carbomer is suitable for preparation of cream or gel..

Lactic Acid Liquid, E270, CAS no.50-21-5, Chemical Formula C3H6O3, is a carboxylic acid manufacturing process through fermentation from corn starch. The lactic acid is a yellowish to colorless liquid, property having a mild acid odor and taste. Many bacterial species produce lactic acid, with Lactobacillus, Bifidobacterium, Streptococcus, Pediococcus and Leuconostoc. Lactic acid used as acid ingredient in sour dairy products, fermented fruits and vegetables and in sausages.
