S M Edwards et al.
Photodermatology, photoimmunology & photomedicine, 10(3), 111-117 (1994-06-01)
The ability to accurately predict the phototoxic potential of personal and skin care products remains a key element in assessing the safety of premarketed products. To find a reliable in vitro alternative test for photoirritancy, the European Commission and the

A PABA ester-oxybenzone preparation is superior to PABA or sulisobenzone alone in protecting the skin from methoxsalen-induced ultraviolet A (UVA) phototoxicity after water substantivity challenge. Such a mixture would be useful as a UVA screen for uninvolved or actinically damaged
C Augustin et al.
Photodermatology, photoimmunology & photomedicine, 13(1-2), 27-36 (1997-02-01)
Phototoxicity inducing in vivo photoirritation, a reversible inflammatory reaction of the skin after chemical contact and UVA radiation exposure, is increasingly observed as a side effect associated with the use of both cosmetics and systemic drugs. In order to systematically

2-Hydroxy-4-methoxybenzophenone and 2-hydroxy-4-methoxybenzophenone-5-sulphonic acid, commonly known as benzophenone-3 (BZ3) and benzophenone-4 (BZ4), respectively, are substances widely used as UV filters in cosmetic products in order to absorb UV radiation and protect human skin from direct exposure to the deleterious wavelengths
N Negreira et al.
Analytica chimica acta, 743, 101-110 (2012-08-14)
The stability of the UV filter benzophenone-4 (BP-4) in free chlorine-containing water was investigated, for the first time, by liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QqTOF-MS). High mass accuracy and resolution capabilities of this hybrid mass spectrometer were used for
