Carbomer 940 is a white powder, crosslinked polyacrylic acid that is polymerized in a toxicologically-preferred cosolvent system. Its self-wetting properties and low dusting make it extremely easy to use for efficient processing. It is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams. Its short flow, non-drip properties are ideal for applications such as clear gels, hydroalcholic gels, creams, and lotions Carbomer 940 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. Name Carbomer 940 Appearance White Powder Purity 99.9% CAS 9003-01-4 Solvent Dichloromethane PH Value 2.7~3.5 Viscosity 40000-60000 Carboxylic acid groups 56~68% Loss on drying ≤2.0% Shelf Life 24 Months     US Pharmacopoeia(USP 36 NF 31) 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.). Carbomer is an excellent suspension agent, stabilizer, emulsifier and the most effective water-soluble thickener. 1. Carbomer Widely used in skin care lotion, cream, transparent skin care gel, hair styling gel; 2. Carbomer widely used in shampoo and shower gel. Let them condense into their proper shape. 3.Add it to cosmetics to make them look better in both texture and shape. The advanced cosmetics we buyed were all processed by this step.
