Carbopol 2020, also called Carbomer 2020 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 .
