    摘要: Cosmetic composition containing, by way of a compound screening cut UV of wavelengths 280-380 nm, a 5-benzylidene-3-oxacyclopentanone of formula (I): ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 denote C.sub.1 -C.sub.8 alkyl, aralkyl or aryl, or alternatively R.sub.1 and R.sub.2 and/or R.sub.3 and R.sub.4 form, with the carbon to which they are attached, a saturated 5- or 6-membered ring, andR.sub.5, R.sub.6 and R.sub.7 denote H, C.sub.1 -C.sub.8 alkyl, C.sub.2 -C.sub.8 alkenyl, C.sub.1 -C.sub.12 alkoxy, C.sub.2 -C.sub.8 alkenyloxy, C.sub.2 -C.sub.12 acyloxy, benzyloxy or --COOR.sub.10 where R.sub.10 is a C.sub.1 --C.sub.8 alkyl, hydrogen, an alkali metal or alkaline earth metal or a radical derived from an amine, it also being possible for one of the substituents R.sub.5, R.sub.6 and R.sub.7 to denote a radical ##STR2## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the above meanings. This composition can be a protective composition for the human epidermis or the hair or an antisun composition.New compounds of formula (I) in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7, have the same meanings, R.sub.6 being other than hydrogen, methyl and methoxy.
