CARBOMER 940 (Polyacrylic Acid / PAA, CAS 9003-01-4) is a high molecular weight crosslinked polyacrylic acid polymer. As one of the most classic carbomer grades, it delivers exceptional thickening efficiency and outstanding clarity, making it indispensable for formulators.
Product Overview
CARBOMER 940 appears as a white, loose powder. Its crosslinked structure provides excellent thickening, suspension, and rheology modification. At 0.5% concentration in water after neutralization, it forms a clear gel with viscosity of 40,000–60,000 cps. Key advantages include batch-to-batch consistency and broad pH compatibility.
Applications
Cosmetics & Personal Care: Ideal for facial gels, hand gels, and sanitizers, providing a refreshing non-tacky feel. In lotions and creams, it imparts silky texture and stability. In hair gels, it forms clear elastic structures.
Pharmaceuticals: Widely used in topical gels, creams, and drug delivery systems. Studies confirm carbomer 940 enables sustained release in metronidazole buccal tablets and uniform dispersibility in clemastine fumarate gels.
Industrial: Used in water treatment, coatings, adhesives, and specialty chemicals for viscosity control.
