A New Multifunctional Liquid Polymer for Skin Care Systems

INTRODUCTION

Lubrizol Advanced Materials, Inc. (LZAM), has developed a multifunctional synthetic polymer based on acrylate chemistry that offers improved efficiency as an emulsifier, thickener and stabilizer; ease of use, unique sensory properties, and improved electrolyte compatibility. This new polymer was designed as experimental polymer 893 (EXP-893) and is to be marketed under the trade name of Novemer™ EC- 2 polymer. It has a designated INCI name of Sodium Acrylates/ Beheneth-25 Methacrylate Crosspolymer (and) Hydrogenated Polydecene (and) Lauryl Glucoside.

This material is polymerized in an emulsion vehicle and is delivered in liquid form. The polymer is synthesized within an internal water phase that is pre-emulsified into hydrogenated polydecene. Based on acrylic acid, this polymer is anionic and is partially neutralized with sodium hydroxide prior to polymerization. This gives the formulator the benefit of rapid thickening and rheological modification by simply adding the material to water with agitation. Because it is lightly crosslinked, highly branched, and contains very low levels of high HLB emulsifier, Novemer™ EC-2 polymer works to emulsify or co-emulsify a large variety of oil phase ingredients.
