    摘要: A novel aqueous organopolysiloxane emulsion composition of the oil-in-water type suitable as an additive ingredient in toiletry preparations for hair-care treatment, of which the organopolysiloxane particles have a relatively large volume-average particle diameter of 3 to 100 .mu.m as emulsified by using a quaternary ammonium chloride as a cationic surface active agent. The emulsion composition is advantageous in respect of the improved stability of the emulsion and increased retention on the hair treated with the hair-care composition. The emulsion composition is prepared in a process comprising the steps of: mixing the organopolysiloxane and the cationic surface active agent with a relatively small volume of water; vigorously agitating the mixture so as to cause phase inversion into an oil-in-water base emulsion; and diluting the base emulsion with an additional volume of water, optionally, containing the cationic surface active agent.

    摘要: An oil-in-water aqueous organopolysiloxane emulsion suitable as an adjuvant, in particular, in a toiletry preparation such as a hair-care treatment preparation is disclosed by using a unique emulsification system including a quaternary ammonium chloride as a cationic surface active agent, in order to provide a solution for the problem of a dilemma between the use of a C.sub.16 or lower-alkyl quaternary ammonium salt having high emulsification power but exhibiting irritativeness to the human body and the use of a higher-alkyl quaternary ammonium salt having lower emulsification power but exhibiting no irritativeness. The emulsion composition comprises: (A) a high-polymeric organopolysiloxane mixed with and diluted by an organopolysiloxane of a lower viscosity; (B) a quaternary ammonium chloride having 1 or 2 stearyl or behenyl groups; (C) a polyoxyalkylene-modified organopolysiloxane or a polyhydric alcohol as an activity-promoting agent for the component (B); and (D) water each in a specified weight proportion. The emulsion can be prepared by first forming a water-in-oil emulsion from the respective ingredients though with a reduced amount of water, then effecting phase inversion of the emulsion by continued agitation from the water-in-oil emulsion to an oil-in-water emulsion; and diluting the emulsion with an additional amount of water.
