Abstract
Bleaching agents with improved resistance to oil separation and better miscibility with dye-containing formulations comprise—in relation to their weight—from about 0.015 to about 10 wt.-% ethylene octene copolymer(s), from about 5 to about 70 wt.-% oil component(s), from about 1 to about 70 wt.-% peroxydisulfate(s) chosen from the group of sodium peroxodisulfate and/or potassium peroxodisulfate and/or ammonium peroxodisulfate, and ≦1 wt.-% free water.
Claims20
An agent for lightening keratin fibers, comprising—based on its weight
- a) from about 0.015 to about 10% by weight of ethylene-octene copolymer(s),
- b) from about 5 to about 70% by weight of oil component(s),
- c) from about 1 to about 70% by weight of peroxodisulfate(s) chosen from the group of sodium peroxodisulfate and/or potassium peroxodisulfate and/or ammonium peroxodisulfate,
- d) ≦about 1% by weight free water.
A method for the color change of keratin fibers in which at least two preparations (A) and (B) packaged separately from each other, of which preparation (A) comprises at least one persulphate and preparation (B) comprises at least one oxidizing agent, are mixed to form an application mixture, wherein the application mixture is applied to the fibers and is rinsed off again after an exposure time, and wherein preparation (A) comprises
- a) from about 0.015 to about 10% by weight of ethylene-octene copolymer(s),
- b) from about 5 to about 70% by weight of oil component(s),
- c) from about 1 to about 70% by weight of peroxodisulfate(s) chosen from the group of sodium peroxodisulfate and/or potassium peroxodisulfate,
- d) ≦about 1% by weight of free water.
An agent for lightening keratin fibers, comprising—based on its weight,
- a) from about 0.4 to about 3% by weight of ethylene-octene copolymer(s),
- b) from about 32.5 to about 50% by weight, of oil(s) chosen from the group of paraffin oil, polyisobutene, the alkylbenzoates, isopropyl palmitate, the C14-22-alkanes, isononyl isononanoate, or combinations thereof,
- c) from about 12.5 to about 45% by weight of peroxodisulfate(s) chosen from the group of sodium peroxodisulfate and/or potassium peroxydisulfate,
- d) ≦about 1% by weight free water.
