About
A plant-based polymer that provides a smooth, powdery feel and oil-absorption in cosmetic formulations, often used as a natural alternative to synthetic polymers.
Tapioca Starch Crosspolymer is a modified tapioca starch produced by crosslinking tapioca starch with epichlorohydrin, creating a polymer with improved stability, oil-absorption capacity, and sensory properties compared to native starch. Epichlorohydrin (CAS 106-89-8) is used in the crosslinking reaction but residual levels in the finished ingredient are typically extremely low due to the reaction process and EU manufacturing standards. The ingredient is used as a viscosity controller, absorbent, and skin conditioning agent. It is not specifically restricted under EU Regulation 1223/2009, though epichlorohydrin residual levels are regulated as a potential genotoxic carcinogen in food and cosmetic packaging contexts.
Skin benefits
- Oil absorption and mattifying
- Smooth powdery skin feel
- Viscosity control
- Improves product texture
- Natural-derived polymer
Known concerns
- Trace epichlorohydrin residual from crosslinking reaction (manufacturing controlled)
- Generally very safe but sensitivity possible
- Modified starch concerns for corn/tapioca allergies (cross-reactivity unlikely)
