Pearlescent surfactant compositions are prepared at a temperature of from about 10° C. to about 45° C. by providing an aqueous surfactant solution and then contacting the aqueous surfactant solution with a composition comprised of a pearlizing wax and a polyol ester.
摘要:
Quaternary surfactants of the formula (I), wherein R1CO is a linear or branched, saturated or unsaturated, optionally hydroxy-functionalized acyl radical having 6 to 22 carbon atoms and 0, 1, 2 or 3 double bonds, R2 is a CH2COOH radical, an alkyl radical having 1 to 4 carbon atoms, a CH2CH2OH or a CH2CH2OCH2CH2OH group, and X is halide, alkyl sulfate, alkyl carbonate or alkyl phosphate, are useful as surfactants in cosmetic and pharmaceutical preparations. Aqueous solutions above 50% by weight of the surfactants are flowable and pumpable.
摘要:
A process for making solid sugar surfactants involving: (a) providing a glycose component; (b) acetalizing the glycose component with a fatty alcohol to form a technical mixture containing excess fatty alcohol and alkyl and/or alkenyl oligoglycoside; and (c) contacting the technical mixture with an extractant to form a solid phase containing the extractant, a predominant part of alkyl and/or alkenyl oligoglycoside and a small amount of fatty alcohol, and a liquid phase containing a predominant part of the fatty alcohol.
摘要:
Surfactant granules are made by the process comprising the steps of (1) mixing an aqueous nonionic surfactant paste and an aqueous solution of an organic polymeric carrier; (2) simultaneously granulating and drying the mixture from step (1) in a fluidized bed to form a granulated nonionic surfactant. The surfactant granules are dust-free, flowable, storage-stable, show no tendency toward clumping and are readily soluble in cold water.
