Oil-in-water organopolysiloxane emulsion and method for the preparation thereof |
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.
