Carbomer
CAS NO.: 9007-20-9 (54182-57-9) Molecular Formula：-【-CH2-CH-】N-COOH
Molecular Structure:
Description:
Carbomer is a term used for a series of polymers primarily made from Acrylic Acid. The Carbomers are white, fluffy powders but are frequently used as gels in cosmetics and personal care products. Carbomers can be found in a wide variety of product types including skin, hair, nail, and makeup products, as well as dentifrices.
Specification:
Carbomer can produce permanent emulsion with a lower viscosity, and the colloid produced by suspensions has a high transparency.
Specification:

Usages:
Carbomer has a high viscosity and a good tackifying effect. 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 aAcid 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, thus Carbomer is suitable for preparation of cream or gel. Besides, Carbomer has a simple process technique, a good stability, and you will feel comfortable after use, therefore Carbomer has achieved a wider application in the partial administration, especially in the skin and the gel for eyes. These polymers are used to optimize the rheological properties of aqueous solution.
Packing:
Carbomer is packed in 20kg cardboard drums.
