Carbpmer

Carbomer is a term used for a series of polymers primarily made from acrylic acid. The Carbomers are white, fluffy powders but are frequently used as gels in cosmetics and personal care products. Carbomer 940 polymer is a white powder, crosslinked polyacrylic acid polymer. 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, hydroalcoholic gels, and creams.

Carbomer Advantages:
Very efficient water thickening using <1% polymer (no electrolytes). Can make aqueous or alcoholic clear gels. Very efficient at suspending solids and stabilizing emulsions due to the high yield value of gels. Can make emulsifier free oil in water crème gel formulations. Can make stable water in oil in water emulsion. Excellent skin feel (<.5%) and shear thinning rheology. Carbomer Formulating Tips Carbomers can easily be added to emulsions by addition to the oil phase prior to emulsification. Easy to disperse powdered grades are preferred when dispersing directly into water. Adding electrolyte or small amounts of acid to the water phase prior to Carbomer addition significantly improves its dispersion by reducing solution viscosity. Up to 5% dispersions of Carbomer in water can typically be made with this approach. Use Triisopropanolamine (Dow Chemical) or Neutrol® TE (BASF) to neutralize Carbomer when gelling up to 90% ethanol. Use granulated grades to reduce dusting issues during manufacturing. Be very careful in qualifying new suppliers for an existing Carbomer. These rarely have the same performance characteristics. Carbomers are more sensitive to shear after neutralization than before. Carbomers are UV sensitive. You need to incorporate a UV absorber into gels when using clear packaging.
