Abstract

The purpose of this work was to identify the range of formulation possibilities using a new W/O silicone glycerol (PEG-Free) emulsifier, Dow Corning® ES-5600 Silicone Glycerol Emulsifier. This emulsifier has (poly)oxyalkyenes or (poly)glycerol derivatives as PolyEthyleneGlycol-free hydrophilic groups. The presence of dual hydrophobic portions in the emulsifier structure, alkyl and silicone dendrimer, improve the compatibility with both organic and silicone oils leading to a wider range of oil type tolerance. The dendrimer is unique in its high branching and methyl packed structure, and can give different surface properties or sensory profiles compared to ordinary PDMS (polydimethylsiloxane) branching. The purpose of this study was to complete the work previously conducted and disclosed in IPCOM000223255D publication, “Formulation possibilities with new PEG-free silicone emulsifier” and to evaluate new benefits and formulation possibilities using this type of silicone glycerol emulsifiers as well as the possible combinations with a broad range of cosmetic ingredients covering all types of applications such as skin and hair care formulations and more specifically foundations and sunscreens. This study demonstrates the possibilities for formulating Dow Corning® ES-5600 Silicone Glycerol Emulsifier in all types of formulations, its ease of use and its ability to provide new types of texture and sensory feel as well as its high pigments and particles dispersions capabilities, improved over current silicone w/o emulsifiers, making it a good candidate to formulate color cosmetics and sun care products.

Introduction

Silicone emulsifiers have been used for more than 20 years and became very popular in skin care products providing non-tacky sensory feel to consumers. One of the issues with these ordinary emulsifiers available on the market today is that they contain Ethylene Oxide functionalities. Indeed, interest in PEG-free is driven by the concern over the potential for skin irritation and the negative perception of Oekotest related to PEG-containing products.

Another issue of these ordinary silicone emulsifiers is their lower oil phase flexibility; mainly neat silicone oils, blend of silicone and organic oils, preferably of low polarity. An emulsifier able to emulsify a broader range of oil phase was needed especially for oil out systems.
