  • Publication number: 20180193234
    Abstract: A method of preparing an oil-in-water emulsion comprises combining (A) an organopolysiloxane including at least two silicon-bonded hydrolysable or hydroxyl groups and (B) an organic oil to give a mixture. The method further comprises combining the mixture, (C) an aqueous medium and (D) a surfactant to form an initial emulsion. Finally, the method comprises contacting the organopolysiloxane (A) with (D1) an organic acid catalyst to polymerize the organopolysiloxane (A) to give (A1) a high molecular weight organopolysiloxane and the oil-in-water emulsion. A personal care composition comprising the oil-in-water emulsion and a personal care ingredient is also disclosed.

  • Publication number: 20120107256
    Abstract: The invention provides an aqueous emulsion for use in a personal care, health care or household care composition. This emulsion comprises at least 1% by weight of a waxy material having a melting point of at least 10.5° C. and at least 1% by weight of an organopolysiloxane which is not miscible with the waxy material. The emulsion also contains an oil having a melting point below 10° C., the oil being miscible with the waxy material when melted and being present in a weight ratio of oil to waxy material in the range 5:95 to 95:5. This permits to obtain stable emulsion at low temperature.
