INGREDIENT OVERVIEW
Carbomer 940 Powder
Carbomer 940 is a high-performance polymer used in cosmetic formulations to create clear gels and control viscosity. It is widely used in serums, gels, and emulsions where precise rheology and clarity are required.
Our carbomer 940 is supplied as a cosmetic-grade powder with high viscosity performance. It is selected for its purity, low residual solvent content, and consistent formulation performance.
In formulation, carbomer provides precise viscosity control and enables the creation of clear, stable gel systems when properly neutralised.

FORMULATION NOTES
Processing notes
Disperse in water phase, then neutralise (e.g. NaOH or TEA) to activate thickening.
Compatibility notes
- Compatible with most cosmetic ingredients
- Sensitive to electrolytes at high levels
- Works well in controlled systems
pH notes
Requires neutralisation (typically pH ~5.5–7) to develop viscosity.
Formulation examples
Clear gel serum

SENSORY PROFILE
Carbomer creates smooth, clean, non-stringy gels with a more refined sensory profile compared to natural gums. Sensory outcome is formulation-dependent; bench testing is recommended.
