Carbopol, also known as carbomer, is an acrylic crosslinking resin crosslinked with acrylic acid by pentaerythritol and so on. It is a very important rheology regulator. After neutralization, Carbomer is an excellent gel matrix with thickening, suspension and other important uses. It has simple process and good stability. It is widely used in emulsion, cream and gel.
Chemical Name: Cross-linked Polyacrylic Acid Resin
Molecular Structure: – [-CH2-CH-]N-COOH
Appearance :white loose powder
PH Value: 2.5-3.5
Moisture content %: ≤2.0%
Viscosity: 20000～40000 mPa.s
Carboxylic acid Content %: 56.0—68.0%
