Product Detail


Product Tags

Name: Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Carbopol UIltrez 21: acrylate /C10-30 alkyl acrylate cross linked copolymer, for short denaturation, for gel, washing cleaning products, high electrolyte products, cream, emulsion.


Carbomer 21 Carbopol 21 is a hydrophobically modified crosslinked polyacrylate polymer. It acts as high-efficient & low-dosage thickener and suspending agent as other traditional carbomer resin, also provides electrolyte tolerance and unique sensory benefits in formulas. It can quickly and easily self-wetting without any mixing required. It can be used in a variety of personal care applications.

Formula Guidelines

Typically used at a level of 0.2-1.5%.


Carbomer is not compatible with phenol, cationic polymer, strong acid and high concentration electrolyte. Some antimicrobial agents should also be avoided or used in low concentrations. Trace amounts of iron or other transition metals can catalyze the degradation of carbomer dispersion. Carbomer can produce a lot of heat when it contacts with strong alkali substances such as ammonia, sodium hydroxide, potassium hydroxide or strong basic organic amines. Some drugs containing amino functional groups can form water-soluble complexes with carbomer. Usually, this situation can be prevented by adjusting the solubility parameters of the liquid with appropriate alcohols or polyols.
Carbomer can also form pH dependent complexes with some polymer excipients, which can adjust the solubility parameters and also play a role in this condition.
Following operations should be avoided, otherwise result in loss of viscosity.Constant stir or high-speed shear after neutralization UV irradiation.
