Naturally-Derived Emulsifier and Emulsion Stabilizer

Cola®Fax CPE-K MB is a naturally-derived, excellent water soluble O/W emulsifier and emulsion stabilizer. It can be used as the primary emulsifier, combining with low HLB co-emulsifiers to achieve highly stable emulsions. Cola®Fax CPE-K MB is easily dissolved into the hot water phase during emulsion processing. Cola®Fax CPE-K MB, at low use concentrates, will enhance the stability of any emulsion and at higher concentrations will aid in building viscosity of creams and lotions. It can replace Stearic acid salts in most preparations. Cola®Fax CPE-K MB is ideally suited for use in many dermatological and personal care products providing a silky powdery afterfeel. Cola®Fax CPE-K MB is completely non-irritating to skin.

Cola®Fax CPE-K MB is “Derived Natural” with a Natural Origin Index of 1.00 in accordance with ISO 16128 guideline.
