Hydroxyethyl Acrylate / Sodium Acryloyldimethyl Taurate Copolymer

Hydroxyethyl Acrylate / Sodium Acryloyldimethyl Taurate Copolymer – Versatile Thickener, Stabilizer, and Texture Enhancer for Cosmetics

Basic Information

• CAS Number: 111286-86-3

• INCI Name: Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

• Appearance: Powder or liquid dispersion (depending on grade)

• pH Range: 3–12

• Recommended Usage: 0.3–3.0%

Overview
Hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer is a synthetic polymer widely used in cosmetic and personal care formulations. It functions primarily as a stabilizer, texture enhancer, dispersing agent, and opacifier. This versatile ingredient is frequently combined with isohexadecane, polysorbates, and silicones to create appealing aesthetics and transformative gel-cream textures.

Key Properties

• Thickening and gelling: Produces pleasant, non-sticky, and supple textures at low usage levels.

• Emulsification and stabilization: Effectively stabilizes and emulsifies oils in water-based formulations.

• Broad pH tolerance: Functions effectively across a wide pH range (3–12), making it suitable for low-pH exfoliants and other active formulations.

• Texture modulation: Influences how quickly a product “breaks” on the skin, enabling transformative gel-cream textures.

• Electrolyte resistance: Maintains performance in the presence of electrolytes.

• EO‑free: Ethylene oxide‑free, aligning with clean beauty trends.

Applications

• Skin care: Moisturizers, serums, sunscreens, and exfoliants – provides smooth, velvety feel and stable textures.

• Makeup: Foundations, primers, and color cosmetics – improves application, wear, and aesthetic appeal.

• Hair care: Styling products and conditioners – enhances spreadability and sensory feel.

• Hand sanitizers: Used in gel formulations.

Key Benefits

• Effective thickening at low concentrations.

• Stable emulsion formation across a broad pH range.

• Non-sticky, supple, and velvety skin feel.

• Compatible with a wide range of cosmetic ingredients.

• EO‑free and suitable for clean formulations.

• Supports cold process dispersion.

Recommended Use
Typical usage levels range from 0.3% to 3.0% of the formulation. For optimal performance, disperse in water with moderate agitation. Liquid grades allow for end‑of‑process viscosity adjustment. Can be used in both rinse‑off and leave‑on products.

Safety and Handling

• Generally recognized as safe for use in cosmetics at recommended concentrations.

• Low irritation potential; well‑tolerated by skin.

• Store in a cool, dry place, away from direct sunlight and moisture.

• Use appropriate personal protective equipment (gloves, safety goggles) when handling.

Quality Assurance
Each batch is tested for viscosity, pH, and stability to ensure consistent performance.
