General description

2-Ethylhexyl 4-(dimethylamino)benzoate is an organic UV filter widely used in the preparation of sunscreens and ultrathin films of acrylates.

Application

  • Study of the photochemical transformation of 2-ethylhexyl 4-(dimethylamino) benzoate (OD-PABA) under conditions relevant to surface waters: This research investigates the photochemical behavior and transformation products of 2-ethylhexyl 4-(dimethylamino)benzoate in aquatic environments, highlighting its environmental impact (Calza et al., 2016).
  • Photoprotection or photodamage: a direct observation of nonradiative dynamics from 2-ethylhexyl 4-dimethylaminobenzoate sunscreen agent: The paper provides insights into the nonradiative dynamics of 2-ethylhexyl 4-dimethylaminobenzoate, assessing its effectiveness as a sunscreen agent and potential for photodamage (Ma et al., 2018).
  • Bioaccumulation and biomagnification of 2-ethylhexyl-4-dimethylaminobenzoate in aquatic animals: This study examines the bioaccumulation and biomagnification potential of 2-ethylhexyl-4-dimethylaminobenzoate in aquatic organisms, providing valuable data on its environmental persistence and effects (Lu et al., 2018).

The in vivo metabolism of the xenobiotic agent 2-ethylhexyl 4-(N,N-dimethylamino)benzoate (EDP), a UV filter commonly used in sunscreen cosmetic products, was studied by targeting metabolomics analysis in human urine. The metabolomic study involved the use of urine from male and

Employing thermal analysis, we investigated the mechanism of action of novel enhancers and probed phospholipid (PL) versus stratum corneum lipid (SCL) liposomes as model membranes. The enhancers included octyl salicylate (OS), padimate O (PADO) and 2-(1-nonyl)-1,3-dioxolane (ND). The negative controls

We describe an in vitro approach to assessing the potential genotoxicity of illuminated sunscreens. The photomutagenic sunscreen Padimate-O attacks DNA on illumination with simulated sunlight, producing strand breaks and lesions that are labile to N,N'-dimethylethylenediamine but few, if any, cyclobutane
