Cola®Fax CPE-K is an excellent water-soluble emulsifier designed to be used as a coemulsifier with low HLB surfactants. Cola®Fax CPE-K is completely non-irritating to skin. Cola®Fax CPE-K is easily dissolved into the hot water phase during emulsion processing. Cola®Fax CPE-K, at low use concentrates, will enhance the stability of any emulsion and thicken creams and lotions. It can replace TEA-stearate in most preparations.
