摘要:
This invention describes a new agent for cutaneous photoprotection against UVA (I and II) and UVB radiation that contains an aqueous extract obtained from a plant in the Gramineae family from the Antarctic Continent (Deschampsia Antarctica), which presents both antioxidant and dissipation of excess UV radiation properties.
摘要:
The present invention relates to a composition comprising (i) a compound A that absorbs in the near visible- ultraviolet A (UVA) region and (ii) a compound B that absorbs in the ultraviolet B (UVB) region, wherein at least one of said compounds A or B is a compound of formula (I) wherein Y represents an optionally substituted aryl or styryl-aryl group, R 1 , R 2 , R 3 and R 4 independently of each other represent H, OH, OR a, NH 2 , NHR a , NR a R b , NO 2 or halogen; wherein R a and R b independently of each other represent C 1 -C 10 alkyl; and R 5 and R 6 independently of each other represent H, or alternatively R 5 and R 6 together form a C-C bond between the carbon atoms to which they are bound. The invention also relates to the use of said compound of formula (I) in the preparation of a photoprotective composition and to the related cosmetic treatment.
