Abstract

The next generation carboxy elastomer is a new alternative to the silicone elastomer technologies available on the market, featuring extended wear properties and comfort wear. While being similar to the first generation in areas of flexibility, organic compatibility and rheology modification, it showed improved performance in various aspects including resistance to wash-off, oil, sebum or mechanical friction and has a unique ability to incorporate water and polar solvents into the elastomer blend. The purpose of this work was to evaluate the formulation possibilities, and long-lasting performance, with new silicone carboxy elastomer gels as well as the possible combinations with a broad range of cosmetic ingredients covering all types of applications.

A New Silicone Elastomer for use in Beauty Care Applications

Authors: Mary Kay Crofoot, Roxanne Haller, Ken Zimmerman (Dow Corning Corporation, USA, Midland, MI) Silicone elastomers have been used in the personal care market for several years to give superior aesthetic enhancement to many personal care applications. These materials are based on crosslinked siloxane polymers and have been used in a variety of applications, such as color cosmetics, skin care and hair care. This research disclosure covers a next generation elastomer that has been designed to provide improved substantivity through the addition of carboxylic acid (carboxy) functionality and the use in various applications. The composition of these new blends and their use in Personal Care applications have been described in the following patents: WO2015066161, WO2015066165, WO2015066199, WO2015167963. The patents highlight the potential for use across a wide range of Beauty Care applications such as color cosmetics, anti-aging skin care, soft focus/wrinkle masking, sun care, anti-perspirant/deodorants, skin and body creams, shampoos, conditioners and so on. The next generation carboxy elastomer is a new alternative to the silicone elastomer technologies available on the market, featuring extended wear properties and comfort wear. While being similar to the first generation in areas of flexibility, organic compatibility and rheology modification, it showed improved performance in various aspects including resistance to wash-off, oil, sebum or mechanical friction and has a unique ability to incorporate water and polar solvents into the elastomer blend. The purpose of this work was to evaluate the formulation possibilities, and long-lasting performance, with new silicone carboxy elastomer gels as well as the possible combinations with a broad range of cosmetic ingredients covering all types of applications.

Introduction Silicone elastomer gels have been utilized in beauty care applications for more than 15 years and have recently become very popular in skin care products. Several generations of silicone elastomers have been developed over the years to provide improved compatibility with organic ingredients (WO2008085360) and the ability to incorporate water and polar materials (WO2010080755). Common issues with these materials was inability to stay on the skin after application. The new silicone carboxy elastomer gels used in the present work were designed to achieve organic compatibility, the ability to incorporate water and resistance to wash-off, oil, sebum or mechanical friction. The purpose of this work was to evaluate the formulation possibilities and performance, using these new elastomer gels in beauty care applications.

Examples of suitable elastomers, cross-linked compositions, cosmetic components, cosmetically acceptable mediums, and additives are described in US Pub. No. 2016/0199286 A1; entitled “Cosmetic Composition Comprising A Carboxy-Functional Elastomer” and US Pub....
