Carbomer polymer(synonym: Carpobol), chemical name: Carboxypolymethylene. It is high molecular weight cross-linked polymer.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 acryli acid, carbomers as white and fluffy powders .they have the ability to absorb,retain water and swell to many times their original volume.Carbomers codes(934,940,941and 1342)are an indication of molecular weight and the specific components of the polymer.

Usage
934
30500-39400
It offers excellent stability at high viscosity and
produces thick formulations for opaque gels, emulsions, creams and suspensions.
940
40000-100000
It is an extremely efficient rheology modifier capable of
providing high viscosity and forms sparkling clear water or hydroalcoholic gels and creams.
941
4000-11000
The gels produced with this polymer have excellent clarity. Suggested applications include clear gels, hydro-alcoholic gels, and
lotions.
1342
20000-40000
This property makes the product uniquely suitable for aqueous solutions or dispersions containing dissolved salts. In addition, it
has improved compatibility in thickening and imparting yield value to ionic surfactants. Suggested applications include clear
gels, hydro-alcoholic gels, surfactant systems (specialty shampoos, cleaning products, etc.), and high electrolyte systems (aloe
gels, etc.).
Application
For skin care products: hydrophilic thickening agent, stabilizing emulsifier, suspension agent, gel agent, with good transparency,it needs to maintain medium to weak alkalinity to have consistency, so it cannot coexist with acid skin activating ingredients. Inaddition, Carbomer is also afraid of salt, so it cannot add mineral ions, otherwise the consistency will disappear, and it isirritating to eye mucosa.
