COLA FAX CPE ®

CTFA/INCI NAME: Cetyl Phosphate; EINECS # 222-581-1; CAS # 3539-43-3

DESCRIPTION Cola®Fax CPE is an oil soluble long chain organic phosphate ester supplied as a free acid in flake form. It is generally used as a co-emulsifier with low HLB nonionics, and is nonirritating to skin. Cola®Fax CPE is easily dissolved into either phase during emulsion processing and can be neutralized in-situ with various cations. Cola®Fax CPE, at low use concentrations, will enhance the stability of emulsions and thicken cremes and lotions. It can replace TEA-stearate in most preparations. Cola®Fax CPE is ideally suited for use in many dermatological and personal care products. BENEFITS ♦Emulsion stabilizer – overcomes imbalances in HLB emulsifier values for various oil systems. ♦Easy to formulate. Acid form is oil soluble; neutralized salts are water-soluble. ♦Can be substituted for polyacrylic acid type polymers, which are frequently utilized as emulsion stabilizers without increasing viscosity to an unacceptable limit. ♦Physically easier to use than polyacrylic acid. No dispersion, wetting problems or fish eyes in solution. ♦Good rub out and afterfeel. Does not inhibit quick break emulsion properties. ♦Primary emulsifier – provides excellent performance at normal skin pH. ♦Easy to handle flake, no noxious dust particles. VISCOSITY RESPONSE Figure 1 demonstrates the effect Cola®Fax CPE has on emulsion viscosity. At low concentrations, Cola®Fax CPE will effectively increase viscosity and aid in the stabilization of the emulsion system. Formulations containing Cola®Fax CPE will display enhanced shear, heat and freeze-thaw stability. Cola®Fax CPE will also enhance the glossy appearance of cosmetic cremes.
