Abstract
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 a 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 inflam…
