Potassium Carbomer 940
What is Potassium Carbomer 940?
Potassium Carbomer 940 is a pre-neutralized form of Carbomer 940, a high molecular weight crosslinked polyacrylic acid polymer that functions as a thickening agent and stabilizer in skincare formulations. It is neutralized with potassium hydroxide, allowing it to swell and form clear, high-viscosity gels in aqueous systems without requiring additional neutralization during manufacturing. This ingredient is widely used in gels, creams, and lotions for its excellent suspending and emulsifying properties, providing a smooth, non-dripping texture.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Gel forming
Builds a gel network to increase viscosity and structure, improving suspension, spread, and stability in serums, gels, and some emulsions.
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Binding
Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
