CARBOPOL 940
CARBOPOL Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent. Carbomer 940 is cross linked with ethers of pentaerythritol, and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.
Carbopol® 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, hydroalcholic gels, and creams.
Ophthalmic products include prescription and over-the-counter drugs, products for the care of contact lenses, and products used in conjunction with ocular surgery. The routine need to compound sterile ophthalmic products is no longer required with the broad range of commercially manufactured products available today.
The toxicity of carbomers has been summarized by the Cosmetic Ingredient Review Expert Panel in their assessment of the safety of the carbomers for cosmetic ingredients. This assessment and subsequent toxicology testing have demonstrated a low toxicity and irritation potential. Lubrizol has supporting data for dermal, ocular, and oral toxicology testing for Carbopol 940 NF polymer. Bulletin 2 provides a summary of all toxicology studies for Lubrizol’s pharmaceutical grade polymers.
