Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
