Carbomer 940
Description
Carbomer 940 is a high‑efficiency synthetic polymer used as a rheology modifier in cosmetic, personal care and pharmaceutical formulations. It provides very high viscosity and excellent clarity at low use levels in aqueous systems.
After proper dispersion and neutralization, Carbomer 940 forms smooth, stable and transparent gels with good sensory properties, making it especially suitable for clear gel applications.
Functions
- Thickening agent
- Gelling agent
- Rheology modifier
- Emulsion stabilizer
Applications
- Clear gels (hydroalcoholic gels, hand gels, hair gels)
- Creams and lotions
- Serums
- Skin care and personal care products
- Pharmaceutical and industrial formulations
Recommended dosage
- Typically: 0.1 – 1.0%
- (depending on desired viscosity and formulation type)
⚠️ Full thickening is achieved only after neutralization (e.g. NaOH, TEA, aminomethyl propanol).
Key benefits
- Very high thickening efficiency
- Excellent clarity in gel systems
- Smooth texture and good skin feel
- Good formulation stability
- Widely used and well‑established polymer
