Carbopol 940,also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of ac.rylic acid used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics. They may be homopolymers of acr. ylic acid, crosslinked with an all. yl ether pe. ntaerythritol, all. yl ether of sucrose or a.llyl ether of prop.ylene. 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 .
This product is acrylic bonded allyl sucrose or pentaery-thritol allyl -ether polymer. Calculated on dry goods, including carboxylic acid group (-cooh) group - should be 56.0 % ~ 68.0%.
