About

An allyl-ether hydroxypropane sulfonate sodium salt — usually a reactive monomer for cosmetic copolymers rather than a leave-on active. Free residual allyl can mildly irritate, so use is limited.

Skin benefits

  • Reactive sulfonate building block
  • Polymer-grade hydrotrope
  • Improves formula stability

Known concerns

  • Allyl group can be reactive/irritant if unreacted
  • Mainly used as polymer monomer not finished cosmetic
