Title:
REGENERATIVE SUNBLOCK COMPOSITION COMPRISING PHOTOCHROMIC SUBSTANCE OR PHOTOCHROMIC SUBSTANCE-PROTEIN COMPLEX
Document Type and Number:
WIPO Patent Application WO/2014/189230
Kind Code:
A1
Abstract:
A sunblock composition according to the present invention is a sunblock composition comprising a photochromic substance which, when exposed to ultraviolet (UV-A) light, absorbs the UV-A light and is converted to a visible-light or near-infrared (IR-A)-light receptor (Z-form) showing an absorption band of visible light or IR-A light, and which absorbs visible light or IR-A light and is converted to a UV-A-light receptor (E-form) showing an absorption band of UV-A light, when the converted visible-light or IR-A-light receptor is exposed to the visible light or IR-A light.
