The invention discloses a method for dispersing a higher fatty alcohol mixture, which provides a method for dispersing a mixture of natural
fatty alcohol and synthol into water, and belongs to the technical field of
fine chemical preparations. A higher
fatty alcohol emulsion prepared by the method contains the following components: (1) 1 to 30 percent of synthesized higher fatty
alcohol with
carbon number of between 14 and 30; (2) 1 to 15 percent of C12-18 saturated natural higher fatty
alcohol; (3) 1 to 15 percent of paraffin; (4) 0.1 to 5 percent of non-ionic surfactant with MO(EO)m(PO)nH as a general formula; (5) 0.1 to 5 percent of one or more anionic surfactants selected from sulfonated ricinate, sulfonated fatty
glyceride,
alkyl sulfate, alkoxy
sulfate, alkylaryl
sulfonate and
sodium polyoxyethylene alkyl ether sulfate; (6) 0.1 to 5 percent of
thickening agent; and (7) 60 to 95 percent of dispersant (water), wherein M is an initiator group of the non-ionic surfactant,
alkyl or an
benzene ring. The method comprises the following realization steps that: (1) the synthesized higher fatty
alcohol, the natural higher fatty alcohol, the paraffin, the non-ionic surfactant, and the anionic surfactants are mixed according to the proportion, and then the temperature is increased to be between 80 and 95 DEG C; (2) then the water with a temperature of between 60 and 80 DEG C is slowly added into the mixture to begin to emulsify, and the emulsification temperature is kept higher than 60 DEG C during the emulsification; (3) the obtained product passes through a
colloid mill after the adding of hot water; and (4) finally the obtained product is cooled to be between 30 and 40 DEG C, then the
thickening agent is added into the obtained product to be mixed evenly, thus the higher fatty alcohol
emulsion is obtained.
