Method for producing silicone emulsions
09814667 · 2017-11-14 · ·

A method for producing aqueous silicone emulsions containing highly viscous polyorganosiloxanes having a low content of cyclic siloxanes in several steps; the addition of acidic compounds intended to catalyze polycondensation of the polyorganosiloxanes being carried out only after an emulsion is produced in the first step exclusively with nonionogenic emulsifiers, without impairing the rate of the polycondensation reaction.

FABRIC CARE COMPOSITIONS COMPRISING EMULSIONS

Fabric care compositions comprising bi-modal water continuous emulsions are disclosed. In particular, the fabric care 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 fabric care compositions further comprise at least one fabric care ingredient (F). Optionally, the fabric care ingredient (F) is in an acceptable medium. Preparation methods and uses of the fabric care compositions are also disclosed.

PERSONAL CARE COMPOSITION
