Benefits of HEA/Sodium Acryloyldimethyl Taurate Copolymer

A genuinely multifunctional polymer that can simplify a formula by handling thickening, gelling and emulsification at once.

• Cold-Process & Energy-Saving: Disperses and builds viscosity at room temperature, with no heat or hot-process emulsification step — faster, lower-energy manufacturing.
• Thickener + Emulsifier in One: Builds elegant gels and also stabilizes oil-in-water emulsions (the Sepinov™ EMT 10 powder is reported to stabilize oil phases up to about 45%), often reducing the need for a separate emulsifier.
• Wide pH & Electrolyte Tolerance: Performs from roughly pH 3 to 12 and resists electrolytes, so it thickens acidic AHA / exfoliant systems and salt- or active-rich formulas where some carbomers struggle.
• Elegant Sensory & Clarity: Delivers a light, fresh, “satiny,” non-tacky after-feel and can form highly transparent gels.
• Effective at Low Use Levels: Typically used at about 0.3–3%.
• Modern Profile: The Sepinov™ EMT 10 grade is described by its supplier as a non-microplastic polymer, and is ethanol- and AHA/DHA-compatible.

How It Works

It is an anionic, pre-neutralized acrylic copolymer of hydroxyethyl acrylate and sodium acryloyldimethyl taurate. When dispersed in water the polymer chains hydrate, unfurl and swell, entangling into a three-dimensional network that raises viscosity and suspends or gels the phase. Because the polymer is amphiphilic, it also locates at the oil–water interface and forms a stabilizing film around oil droplets — so a single ingredient provides both rheology control and emulsion stabilization, without the heating or high-shear that conventional emulsifiers often require.

Formats & Formulating

It is supplied in two practical forms — a powder (Sepinov™ EMT 10) and liquid pre-dispersions (Simulgel™ NS, Simulgel™ INS 100, Simulgel™ FL and Sepiplus™ S), which are blended with carriers and co-emulsifiers for instant cold dispersion. Add to the water phase under moderate stirring and allow it to hydrate fully; avoid over-shearing once the system has thickened. It is compatible with ethanol and a broad pH range — as with any rheology modifier, confirm performance against high electrolyte loads and strongly cationic systems in your specific formula.
