Carbopol 940 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 codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer
