Colafax Cpe

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 non-irritating 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.
