Abstract
β-Diketone/hydroxylated or carbonated activated cation inorganic/organic complexes are well suited for preventing, avoiding or reducing skin irritation, notably that elicited by exposure to irritant active agents/species or to the external environment.
Claims65
A topically applicable cosmetic/dermatological composition for reducing mammalian skin irritation, comprising an anti-skin-irritant effective amount of at least one compound having the formula (I):
- 3
- in which the radicals R, which may be identical or different, are each a linear or branched, saturated or unsaturated, optionally hydroxylated alkyl or perfluoroalkyl radical having from 1 to 12 carbon atoms;
- the radicals R′, which may be identical or different, are each a linear or branched, saturated or unsaturated, optionally hydroxylated alkyl, alkoxy or perfluoroalkyl radical having from 1 to 12 carbon atoms;
- and X is magnesium, strontium, barium, zinc, manganese or palladium, said compound being in hydrated or nonhydrated form, and a topically applicable, physiologically acceptable medium therefor.
A topically applicable cosmetic/dermatological composition for substantially inhibiting or reducing mammalian skin irritation, comprising an irritant amount of at least one normally skin-irritating active species/product and an anti-irritant effective amount of at least one compound having the formula (I):
- 4
- in which the radicals R, which may be identical or different, are each a linear or branched, saturated or unsaturated, optionally hydroxylated alkyl or perfluoroalkyl radical having from 1 to 12 carbon atoms;
- the radicals R′, which may be identical or different, are each a linear or branched, saturated or unsaturated, optionally hydroxylated alkyl, alkoxy or perfluoroalkyl radical having from 1 to 12 carbon atoms;
- and X is magnesium, strontium, barium, zinc, manganese or palladium, said compound being in hydrated or nonhydrated form, and a topically applicable, physiologically acceptable medium therefor.
