Abstract

Abstract This disclosure describes the potential uses of a new silicone emulsion based on silicone fluid containing certain branched and/or high molecular weight organopolysiloxanes polymer that demonstrates pituitous rheological behavior when delivered from a carrier in personal care applications. One example for this silicone fluid is commercialized under the name Dow Corning® 3901 Liquid Satin Blend. This fluid has a very interesting viscoelastic behavior generating a normal force when submitted to a shear stress. In the following part of this disclosure we will use the generic term ¿Liquid Satin Blend Emulsion¿ to describe this new emulsion. The partial INCI name of this emulsion is ¿Dimethicone / Vinyl Dimethicone Crosspolymer¿ and will be updated depending both on the emulsifier type that will be used to stabilize the silicone droplets and the carrier solvent used to solubilize the silicone polymer. Contrary to the neat pituitous fluid, the emulsion format has improved handling properties but keeps its unique sensory characteristics and stringiness texture although reduced compared to the neat fluid. This Liquid Satin Blend emulsion can be added to many common personal care formulations, including but not limited to hair conditioners, shampoo formulations, sunscreens, color cosmetics, bodywash, etc. to deliver interesting set of benefits such as hair conditioning, styling , gloss, smooth and satin-like skin feel.

Introduction

This disclosure describes the potential uses of a new silicone emulsion based on a silicone fluid containing certain branched and/or high molecular weight organopolysiloxanes polymer that demonstrates pituitous rheological behavior when delivered from a carrier in personal care applications. The partial INCI name of this emulsion is “Dimethicone / Vinyl Dimethicone Crosspolymer”, and will be updated depending both on the emulsifier type that will be used to stabilize the silicone droplets and the carrier solvent used to solubilize the silicone polymer. In the following part of this disclosure we will use the generic term “Liquid Satin Blend Emulsion” to describe this new emulsion.

This emulsion could contain at least 5% by weight of an emulsifier selected from an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric or a combination thereof. As used herein, “emulsifier” refers to any compound or substance that enables the formation of an emulsion. The emulsifier may be selected from any surface active compound or polymer capable of stabilizing emulsions, providing the emulsifier contains at least one anionic, cationic, amphoteric or nonionic surfactants. The particle size distribution of this emulsion could be from 0.1 to 20µm.

The fluid emulsified is actual...
