General description
Avobenzone is an UVA filter. It is used in sunscreen lotions and cosmetic formulations. It has maximum absorption at ca 340–350 nm, decreasing under UV irradiation resulting in loss of the UVA protecting effect. Its photostability is very sensitive as it is stable in polar protic solvent and is photolabile in nonpolar solvents.
Application
Avobenzone may be used as an analytical reference standard for the quantification of the analyte in the following:
Avobenzone may be used to study the photophysical characteristics, photosensitizing activity of a blocked diketo form derived from 4-tert-butyl-4′-methoxydibenzoylmethane (BM-DBM).
- Sunscreen formulations using reversed-phase high-performance liquid chromatography with diode array detection (RP-HPLC-DAD).
- Freshwater, saline water samples, rat plasma and skin layers using liquid chromatography-positive electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) in multiple reaction monitoring mode (MRM).
Avobenzone may be used to study the photophysical characteristics, photosensitizing activity of a blocked diketo form derived from 4-tert-butyl-4′-methoxydibenzoylmethane (BM-DBM).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A major concern raised about photostability studies of sunscreen products is that the photodegradation of sunscreens does not readily translate into changes in product performance. This study examines the correlation between photochemical degradation of sunscreen agents and changes in protection

As an extension of our previous investigations on sunscreen ingredients, the present work was aimed at assessing the possible protective effects of a common UVA-absorbing agent, Parsol 1789 (4-tert-butyl-4'-methoxydibenzoylmethane) in contact with human keratinocytes under UVA illumination. Cell viability was
