General description

Octocrylene is a commercially used UVB filter, termed as an environmental pollutant because of its stability, lipophilic nature, and resistance to sunlight degradation. It is employed as an ingredient in water resistant sunscreen products and high SPF formulations.

Application

Octocrylene may be used as an analytical reference standard for the quantification of the analyte in the following:        
  • Sunscreen formulations using reversed-phase high-performance liquid chromatography (RP-HPLC) technique.   
  • Marine mammals using ultra high-performance liquid chromatography (UHPLC).       
  • Solid lipid nanoparticle systems using high-performance liquid chromatography (HPLC) technique.
