Abstract
Cosmetic or pharmaceutical use of alkylpolyglycosides and/or O-acylated derivatives of glucose for treating hair loss. The compounds have the developed formula (II) where R1 is a radical or a mixture of alkyl or alkenyl radicals; x is from 1 to 15 and/or compounds of the formula (III) where R2 stands for a hydrocarbon chain and R3 represents a C1 to C4 alkyl group or hydrogen; the compounds of the formula (II) not being used in the presence of pyrimidine derivatives.
Claims18
Process for treating hair loss, wherein at least one cosmetic composition comprising in a cosmetically acceptable medium at least one compound of formula:
- R1O(C6H10O5)xH (I)
- corresponding to the structural formula (II):
- in which:
- R1 denotes an alkyl radical having an unbranched or branched C8-C24 chain, or a mixture of such radicals;
- x is a number between 1 and 15;
- and optionally at least one compound corresponding to the formula (III):
- in which R2 represents a saturated or unsaturated, linear hydrocarbon chain containing from 7 to 19 carbon atoms and R3 represents hydrogen or a C1 to C4 lower alkyl group is applied to the hair or scalp, said compound of formula (I) and said compound of formula (III) having hair regrowth activity and/or halting of hair loss activity.
Process for treating hair loss, wherein at least a therapeutical composition comprising in a therapeutically acceptable medium at least one compound of formula:
- R1O(C6H10O5)xH (I)
- corresponding to the structural formula (II):
- in which:
- R1 denotes an alkyl radical having an unbranched or branched C8-C24 chain, or a mixture of such radicals;
- x is a number between 1 and 15;
- and optionally at least one compound corresponding to the formula (III):
- in which R2 represents a saturated or unsaturated, linear hydrocarbon chain containing from 7 to 19 carbon atoms and R3 represents hydrogen or a C1 to C4 lower alkyl group is applied to the hair or the scalp.
Process for the topical therapeutic treatment of hair loss comprising the application to the hair or scalp of a therapeutical composition including at least one compound of formula (III):
- in which R2 represents a saturated or unsaturated, linear hydrocarbon chain containing from 7 to 19 carbon atoms and R3 represents hydrogen or a C1 to C4 lower alkyl group.
