Description

Homosalate is used as a broad-band UV filter in concentrations of up to 10% in the EU or 15% depending upon where the product is used (e.g. in the USA) in sunscreen products alone or in combination with other UV absorbers to protect the skin against harmful effects of the UV radiation.

Sample Use Guides

In Vivo Use Guide
2 mg/cm2 Homosalate was applied to area (2x2 cm) on the volar side of the forearm.
Route of Administration: Other
In Vitro Use Guide
Human full-thickness skin was mounted in a conventional static Franz diffusion cells with a receptor volume of 12.4 ml. The UV filters were readily soluble in the receptor fluid. Epidermis and dermis separated by the hot plate method (60°C for 2 min) and punch biopsies (8 mm) from the tissue samples were taken. Homosalate did not permeate through the skin after 6 h application.
