Product Description:
Carbomer also called Carbobol or Carboxypoly-methylene is a generic name for synthetic high molecular
weight polymers of acrylic acid used as thickening, dispersing, suspending and emulsifying agents in
pharmaceuticals and cosmetics. They may be homopolymers of acrylic acid, crosslinked with an allyl
ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. Carbomers are found in the market
as white and fluffy powders. They have the ability to absorb, retain water and swell to many times their
original volume. Carbomers codes (910, 934, 940, 941 and 934P) are an indication of molecular weight
and the specific components of the polymer.
Recommendedb applications:
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
cid 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.
