What is Amiloxate?

Amiloxate (CAS 71617-10-2), also known as isoamyl p-methoxycinnamate, is an organic UV filter used in sun care and cosmetic formulations.

Where is Amiloxate used?

  • Sunscreens: UVB-absorbing active at concentrations permitted under regional cosmetic regulations
  • Daily-wear cosmetics such as moisturizers and foundations: incidental UV protection
  • Lip care and hair protection products: UVB defense alongside aesthetic elegance
  • It absorbs UVB radiation, protecting skin and light-sensitive formulations from solar degradation.

Good to know: Its oil-soluble nature makes it compatible with emollient systems, allowing direct incorporation into the oil phase of emulsions. Suppliers typically align documentation to INCI and regional regulatory requirements, including the EU Cosmetics Regulation and relevant positive lists.
