Carbomer 940

Carbomer is a synthetic polymer used in cosmetic formulations to create clear gels and control viscosity.

Key benefits

Creates clear gels
Provides precise viscosity control
High efficiency thickener
Stabilises formulations

Behaviour in formulations

Carbomer swells in water and forms a gel network when neutralised, increasing viscosity.

Disperse in water phase, then neutralise (e.g. NaOH or TEA) to activate thickening.

Use level considerations

Use Rate (Min): 0.1
Use Rate (Max): 0.5

Leave-on: 0.1–0.5%
Rinse-off: 0.2–0.5%
High efficiency thickener

Starter Use Rate: 0.2–0.3% for most cosmetic formulations

Typically used at 0.1–0.5% depending on desired viscosity.

Formulation summary

Water dispersible (requires neutralisation)
