摘要:
The invention relates to novel pulverulent cosmetic compositions for bleaching hair, containing at least one oxidizing agent selected from peroxidized compounds, and at least one polymer selected from polyethylene glycol, polypropylene glycol, a derivative of polyethylene glycol, and a derivative of polypropylene glycol, where the polymer is present in an amount of 10 to 27% by weight, the polymer is anhydrous and, at room temperature, both liquid and water-soluble. The invention also relates to a process for the preparation of such compositions and to their use for bleaching hair.
摘要:
A process for preparing a pulverulent, anhydrous hair bleaching composition comprises mixing in a non-solvent medium at room temperature a dry bleaching powder of a peroxygen compound oxidizing agent and at least one anhydrous block and/or random polyoxyethylene/polyoxypropylene copolymer which is liquid and water-soluble at room temperature.

Composition for the treatment of acne containing a dispersion of vesicles of ionic or non-ionic amphiphilic lipids, the vesicles containing in the lipid phase at least one salicylic acid derivative of formula (I): ##STR1## in which R represents a linear or branched C.sub.11 -C.sub.17 alkyl radical; R'.sub.1, R'.sub.2, R'.sub.3, which are identical or different, represent a C.sub.1 -C.sub.18 alkyl or hydroxyalkyl radical, it being possible for one of the radicals R'.sub.1, R'.sub.2 or R'.sub.3 to be a benzyl radical. The derivative of formula (I) serves both as charged lipid and as anti-acne active ingredient. The derivatives of formula (I) in which, when R represents a C.sub.13 -C.sub.17 alkyl radical, R'.sub.1, R'.sub.2, R'.sub.3, when they are identical, do not represent a hydroxyethyl radical.
