Carbopol, also called CarbCarbopol, also called Carbomer 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 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 .
