Energy Efficient Emulsification Using Hydrophobically Modified Alkali Swellable Amphipathic Polymers
Joseph Albanese

What Dr. T.J. Lin refers to as “Low Energy Emulsification (LEE)” may be accomplished several different ways. Any of these will be more environmentally friendly, effectively reduce the carbon footprint of your manufacturing plant and comply with the EPA’s “12 Principles of Green Chemistry”.

Polymers of Acrylic Acid, or PAAs, are widely used in cosmetic emulsions. First, and perhaps still foremost, is the homopolymer Carbomer. However, hydrophobically modified copolymers and crosspolymers of acrylic acid, with their inherent emulsification properties may significantly reduce batch temperatures, shorten compounding times, and increase production capacity. Furthermore, they provide a greater tolerance to electrolytes giving a milder and enhanced skin-feel along with other improved performance attributes.

Two exceptional examples of this type of newer rheology modifier are Acrylates/Vinyl Isodecanoate Crosspolymer and Acrylates/Palmeth-25 Acrylate Copolymer. They are hydrophobically modified alkali swellable associative thickeners with an affinity for both oil and water and provide finished products with the desirable pseudoplastic-type rheology for easy dispensing from packaging and aesthetically pleasing topical application onto hair and skin.

This presentation will show how these copolymers and crosspolymers of acrylic acid can be coupled with LEE manufacturing strategies and also fit in nicely with Dr. Lin’s “less is more” philosophy.

Joseph Albanese is currently the Technical Marketing Manager Personal Care at 3V Inc. During his career in the personal care industry Joe worked for Avon, Shulton, and Colgate-Palmolive in both process and product development groups. His employment on the supply side of the industry included more than 12 years at GAF/ISP (now Ashland) where he went from formulation chemist to Manager of the Hair Care Applications/Tech Service lab. He is a graduate of the F.D.U. Cosmetic Science M.A. Program. He has been a member of the SCC since 1984, former Chair of the New York Chapter and Area I Director for 2012 to 2014.
