  • Liquid chromatographic assay for common sunscreen agents: application to in vivo assessment of skin penetration and systemic absorption in human volunteers. (nih.gov)
  • The purpose of the present study was to develop a reverse-phase high-performance liquid chromatographic (HPLC) assay for quantifying four common sunscreen agents, namely 2-hydroxy-4-methoxybenzophenone, 2-ethylhexyl-p-methoxycinnamate, 2-ethylhexylsalicylate (octylsalicylate) and salicylic acid 3,3,5-trimethcyclohexyl ester (homosalate) in a range of biological matrices. (nih.gov)
  • The assay permits analysis of the sunscreen agents in biological fluids, including bovine serum albumin (BSA) solution, plasma and urine, and in human epidermis. (nih.gov)
  • Results from the preliminary clinical study demonstrate significant penetration of all sunscreen agents into the skin, and oxybenzone and metabolites across the skin. (nih.gov)
