The present invention relates to the use of an .alpha.-tocopherol phosphate, especially in its dl or d form, or an ester thereof, of the general formula ##STR1## in which: R.sub.1 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as the methyl or ethyl radical in particular, or an .alpha.-tocopheryl radical; and R.sub.2 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as methyl or ethyl radical in particular, or an oxyethylene chain of the formula ##STR2## in which R.sub.3 and R.sub.4 independently are a hydrogen atom or a methyl radical and n is an integer greater than or equal to 1, or a salt thereof, for preparing a pharmaceutical, dermatological or cosmetic composition for the prevention or treatment of allergic manifestations such as skin allergy or bronchial asthma, or inflammatory manifestations, or for the prevention or treatment of the harmful effects of free radicals.

Use of an .alpha.-tocopherol phosphate or a derivative thereof for

The present invention relates to a novel composition based on hydrated lipidic lamellar phase or on liposomes and to a cosmetic or pharmaceutical, particularly dermatological composition incorporating it. The hydrated lipidic lamellar phases or the liposomes contain at least in part a derivative of labdane, or a plant extract containing it. The invention reduces hair loss and promotes hair growth.

Composition based on hydrated lipidic lamelar phases or on liposomes

The present invention relates to the use of an .alpha.-tocopherol phosphate, especially in its dl or d form, or an ester thereof, of the general formula ##STR1## in which: R.sub.1 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as the methyl or ethyl radical in particular, or an .alpha.-tocopheryl radical; and R.sub.2 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as a methyl or ethyl radical in particular, or an oxyethylene chain of the formula ##STR2## in which R.sub.3 and R.sub.4 independently are a hydrogen atom or a methyl radical and n is an integer greater than or equal to 1, or a salt thereof, for preparing a pharmaceutical, dermatological or cosmetic composition for the prevention or treatment of allergic manifestations such as skin allergy or bronchial asthma, or inflammatory manifestations, or for the prevention or treatment of the harmful effects of free radicals.

Use of a tocopherol phosphate, other than alpha-tocopherol phosphate, especially in its dl or d form, or one of its esters having general formula (I) in which: R' is hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as the methyl or ethyl radical in particular, R'O is a tocopheryl radical; R' is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as the methyl or ethyl radical in particular, or R'O is an oxyethylene chain, of formula (a) in which R.sub.4 and R.sub.5 are independently a hydrogen atom or a methyl radical, and n is an integer of 1 or over; R.sub.1, R.sub.2 and R.sub.3 are independently a hydrogen atom or a methyl radical, it being understood that R.sub.1, R.sub.2 and R.sub.3 cannot simultaneously be a methyl radical. A represents the groups (b), or (c). The invention also concerns the use of cosmetically or of pharmaceutically acceptable salts of said compound in the preparation of cosmetic or pharmaceutical, especially dermatological, composition characterized by having a reduced allergizing or irritating potential, or used in the prevention or treatment of allergic conditions, such as cutaneous allergy or bronchial or inflammatory asthma, or in the prevention or treatment of the harmful effects of free radicals.

The present invention relates to a novel composition based on hydrated lipidic lamelar phases or on liposomes and to a cosmetic or pharmaceutical, particularly dermatological composition incorporating it. The hydrated lipidic lamelar phases or the liposomes contain at least in part a derivative of labdane, or a plant extract containing it. The invention reduces hair drop and promotes regrowth of hair and also prevents gray hair from appearing and provides a treatment for gray hair.

A method of treating skin or hair for promoting pigmentation wherein a xanthine component, in an amount effective to promote pigmentation, is incorporated in liposomes or hydrated lipidic lamellar phases.
