Products Description of Cremophor (R) A25 CAS#68439-49-6
CETETH25 is a nonionic emulsifier synthesized via the ethoxylation of natural saturated fatty alcohols. Possessing an HLB value ranging from 15 to 17, it acts as an oil-in-water (O/W) emulsifier. When blended with CETETH6, it creates a synergistic emulsifier system that offers powerful emulsifying efficiency even at low addition rates. The emulsions produced feature exceptional stability and a fine, smooth, glossy texture. CETETH25 has favorable tolerance to inorganic salts and maintains stable performance in both acidic and highly alkaline environments. Beyond regular creams and lotions, it is also ideal for fruit acid-containing emulsions and high-alkaline formulations including hair dye creams and depilatory creams, establishing itself as an extremely versatile emulsifier for diverse applications.
