Carbomer 940 is a synthetic high-molecular-weight polymer of acrylic acid used as a thickening, dispersing, suspending, and emulsifying agent in pharmaceuticals and cosmetics. It forms gels when neutralized and is known for its ability to control the viscosity of aqueous solutions.
🏭⚗️ Production
Carbomer 940 is produced by the polymerization of acrylic acid in the presence of a crosslinking agent such as allyl pentaerythritol or other polyfunctional crosslinkers.
🧪 Applications
It is widely used in pharmaceutical formulations like gels, creams, and lotions to improve texture and stability. It is also commonly used in personal care products, including shampoos, conditioners, and facial cleansers, for its thickening and stabilizing properties.
⚠️ Safety
Carbomer 940 is considered safe for use in topical pharmaceutical and cosmetic products. It is generally non-irritating and non-toxic, but proper formulation is necessary to avoid skin irritation due to pH imbalance or high concentrations.
