Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Methoxycinnamoylpropyl Silsesquioxane Silicate is a polymer-bound cinnamate UV filter designed for low skin penetration. It is promising but has less long-term human data than classic filters.

Skin benefits

  • Polymer-bound UV filter intended for sunscreen formulations
  • Reduced skin penetration compared with free cinnamate filters
  • Improves photostability of UVB protection systems
  • Adds silky silicone-like skin feel

Known concerns

  • Silsesquioxane-bound cinnamates still under evolving regulatory review
  • Limited long-term human safety data versus established UV filters
  • Potential for trace free methoxycinnamate impurities
  • Not yet harmonized across all jurisdictions
