Abstract

Pemulen™ EZ-4U polymeric emulsifier, having an INCI name of Acrylates/C10-30 Alkyl Acrylate Crosspolymer, is a high molecular weight cross-linked copolymer of acrylic acid and a hydrophobic C10-30 alkyl acrylate comonomer that is easy-to-disperse, robust and efficient, ethoxylate-free polymeric emulsifier providing emulsion stability, smooth texture, and a pleasant fresh sensory for milder emulsions. Pemulen™ EZ-4U minimizes skin care formulation constraints through simpler processing and greater formulation flexibility in a cost-efficient manner while offering robust emulsion stabilization, freedom from HLB constraints, and stability over a wide pH range, and flexibility for cold or hot process ability all at low use levels. It allows the development of a wide variety of textures from shiny, smooth creams to thin sprayable lotions. Pemulen™ EZ-4U polymeric emulsifier provides a light sensorial profile and robustness to stabilize sophisticated ingredients, such as challenging oil systems, actives, perfumes, UV absorbers, film formers, and optical and sensory enhancers.
