Abstract

The purpose of this work was to evaluate the formulation possibilities with Carboxydecyl trisiloxane as surface treatment, mainly for fine particles. The composition of this silicone fluid and its use in Personal Care have been described in many patents. Among them, WO2009022621, JP2009-155564 and JP2013-256303 mentioned its application as surface treatment for cosmetic use. The purpose of this work was to evaluate the formulation possibilities using this surface treatment materials as well as the possible combinations with a broad range of cosmetic ingredients covering all types of applications such as O/W foundation, compact powders, O/W sunscreen, and anhydrous sunscreens and so on... It was demonstrated that it was possible to formulate fine particles treated with the Carboxydecyl trisiloxane into a broad range of formulations. Not only, it was easy to use but it also provided new types of texture and feel in some cases compared to existing commercial materials.

It was demonstrated that it was possible to formulate fine particles treated with the Carboxydecyl trisiloxane into a broad range of formulations. Not only, it was easy to use but it also provided new types of texture and feel in some cases compared to existing commercial materials.  

Introduction

Silicone fluid has been used around for more than 30 years and became very popular in skin care products thanks to the non-tacky sensory feel they provide to a wide range of formulations.  Hydrogen silicone and alkyl alkoxy silane were developed as surface treatment for fine particles to provide smooth sensory, good water and sebum repellency in skin care products but the sensory performance was not optimum. Carboxydecyl trisiloxane treatment was found to achieve the best balance between the ability to maintain water and sebum repellency while providing smooth sensory feel. The purpose of this work was to evaluate the formulations possibilities using fine particles treated with Carboxydecyl trisiloxane as well as the possible combinations with a broad range of cosmetic ingredients covering all types of applications such as sunscreen and foundations.
