application:

Poly ( PAA ; trade name   Carbomer ) is a   polymer   with the formula (CH ₂ -CHCO ₂ H) _n . It is a derivative of   acid   (CH ₂ =CHCO ₂ H). In addition to the   homopolymers , a variety of copolymers and crosslinked polymers, and partially deprotonated derivatives thereof are known and of commercial value. In a water solution at neutral   pH , PAA is an   anionic   polymer , i.e., many of the side chains of PAA lose their protons and acquire a negative charge. Partially or wholly deprotonated PAAs are   polyelectrolytes , with the ability to absorb and retain water and swell to many times their original volume. These properties - acid-base and water-attracting - are the bases of many applications.
  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.

Carbomer	Viscosity(5% neutral solution)	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.).
