Abstract:
Bi-modal water continuous emulsions are disclosed comprising at least 70 weight percent of: a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant.
Abstract:
Aqueous suspensions of silicate shell microcapsules are disclosed having a core containing a burst aid wherein the silicate shell microcapsules are obtained by; I) mixing an oil phase containing a burst aid and an aqueous solution of a cationic surfactant to form an oil in water emulsion, II) adding a water reactive silicon compound comprising a tetraalkoxysilane to the oil in water emulsion, III) polymerizing the tetraalkoxysilane at the oil/water interface of the emulsion to form a microcapsule having a core containing the oil and a silicate shell.
Abstract:
A process for preparing an aminofunctional silicone emulsion is disclosed comprising: I) forming a mixture of 100 parts of a polydialkylsiloxane having a viscosity of at least 50,000 mm2/s at 23° C., and 0.1 to 100 parts of an aminofunctional organopolysiloxane, II) admixing to the mixture of step I 0.1 to 50 parts of a halide free quaternary ammonium surfactant, and a sufficient amount of water to form an emulsion, III) optionally, further shear mixing the emulsion; and IV) adding a sufficient amount of an acid of the formula H+X− to provide the emulsion with a neutral pH, where X is the same counter ion used in the quaternary ammonium surfactant.
Abstract:
The present invention provides methods for preparing emulsions of silicone fluids having pituitous rheological properties. The present invention also provides emulsions of a silicone fluid having pituitous rheological properties and composition comprising the emulsions. The compositions include, but are not limited to, personal care compositions and compositions for hair shampoo, hair conditioner, hair treatment composition, or skin care product.
Abstract:
A process for preparing bi-modal water emulsions is disclosed comprising: I) forming a mixture comprising; A) 100 parts by weight of a hydrophobic oil, B) 1 to 1000 part by weight of a water continuous emulsion having at least one surfactant, II) admixing additional quantities of the water continuous emulsion and/or water to the mixture from step I) to form a bi-modal emulsion.

Abstract:
Cosmetic compositions comprising bi-modal water continuous emulsions are disclosed. In particular, the cosmetic compositions comprise a bi-modal water continuous emulsion (E) comprising at least 70 weight percent of: a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, and a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant. The cosmetic compositions further comprise at least one cosmetic ingredient (C). Optionally, the cosmetic ingredient (C) is in a cosmetically acceptable medium. Preparation methods and uses of the cosmetic compositions are also disclosed.
