Abstract
The present invention relates to a process for treating keratin fibers such as the hair using a packaging article comprising i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres, preferably water-soluble fibres; ii) at least one anhydrous oxidizing composition, preferably in paste or powder form, comprising at least one anhydrous chemical oxidizing agent, preferably in paste or powder form; it being understood that the oxidizing composition is in one of the cavities defined by the envelope i).
Claims19
A process for treating keratin fibers, the process comprising:
- (i) mixing a packaging article with an aqueous composition comprising hydrogen peroxide to form a mixture having a pH ranging from 7 to 12,
- wherein the packaging article comprises polyvinyl alcohol fibers and defines at least one cavity, and
- wherein the at least one cavity comprises a substantially anhydrous composition comprising:
- at least one chemical oxidizing agent chosen from sodium persulfates, potassium persulfates, ammonium persulfates, or mixtures of two or more thereof, wherein the total amount of chemical oxidizing agents ranges from 30% to 90% by weight, relative to the weight of the substantially anhydrous composition,
- at least one alkaline agent chosen from alkali metal silicates, alkaline-earth metal silicates, alkali metal phosphates, alkaline-earth metal phosphates, alkali metal carbonates, alkaline-earth metal carbonates, or mixtures of two or more thereof, wherein the total amount of alkaline agents ranges from 1% to 25% by weight, relative to the weight of the substantially anhydrous composition,
- at least one anionic surfactant,
- at least one liquid fatty substance,
- at least one compound chosen from polyol stearates, alkali metal stearates, alkaline-earth metal stearates, or mixtures of two or more thereof, and
- at least one thickening polymer;
- (ii) applying the mixture to the keratin fibers;
- (iii) leaving the mixture on the keratin fibers for a leave-on time ranging from 1 minute to 1 hour;
- and
- (iv) rinsing the keratin fibers.

- at least one anionic surfactant chosen from sodium lauryl ether sulfate, sodium lauryl sulfate, or a mixture thereof,
- mineral oil,
- sodium stearate, and
- at least one thickening polymer chosen from guar gum,
- wherein the composition comprises less than 0.5% water by weight, relative to the substantially anhydrous composition;
- (ii) applying the mixture to the keratin fibers;
- (iii) leaving the mixture on the keratin fibers for a leave-on time ranging from 1 minute to 1 hour;
- and
- (iv) rinsing the keratin fibers.
