Abstract
An agent for lightening keratin fibers, which, with regard to its weight, includes 20 to 75 wt. % of oil(s), 0.05 to 5 wt. % of polymer(s) from the group of copolymers of ethylene/propylene/styrene and/or copolymers of butylene/ethylene/styrene, and/or copolymers of butylene/propylene/styrene, and 1 to 70 wt. % of peroxydisulfate(s), wherein the fibers contain 1 to 44 wt. % of potassium peroxydisulfate and 0 to <5 wt. % of sodium peroxydisulfate, and 0 to <5 wt. % of ammonium peroxydisulfate. The agent has increased storage stability, whereby not only the physical stability (settling, phase separation) but also the chemical stability (decomposition of the peroxide salts) is improved.
Claims9
An agent for lightening keratinic fibers, including, based on the weight of the agent,
- a) 20 to 75 wt. % oil(s);
- b) 0.05 to 5 wt. % copolymers of butylene/propylene/styrene;
- c) 1 to 70 wt. % peroxydisulfate(s);
- (d) 2 to 10 wt. % 2-hexyldecan-1-ol;
- (e) 3.5 to 8 wt. % cetearyl alcohol;
- and
- (f) 0.6 to 0.9 wt. % arachyl alcohol (eicosan-1-ol);
- wherein the agent includes
- 1 to 44 wt. % potassium peroxydisulfate,
- 0 to <5 wt. % sodium peroxydisulfate, and
- 0 to <5 wt. % ammonium peroxydisulfate.
A method for changing the color of keratinic fibers, including mixing at least two preparations (A) and (B) packaged separately from each other, of which preparation (A) contains at least one persulfate and preparation (B) contains at least one oxidizing agent, to form an application mixture, and applying the mixture to the fibers and rinsing the mixture off again after an exposure time, wherein the preparation (A) includes
- a) 0 to 75 wt. % oil(s);
- b) 0.05 to 5 wt. % copolymers of butylene/propylene/styrene;
- c) 1 to 44 wt. % potassium peroxydisulfate;
- d) 0 to <5 wt. % sodium peroxydisulfate;
- e) 0 to <5 wt. % ammonium peroxydisulfate;
- f) 2 to 10 wt. % 2-hexyldecan-1-ol;
- g) 3.5 to 8 wt. % cetearyl alcohol;
- and
- h) 0.6 to 0.9 wt. % arachyl alcohol (eicosan-1-ol).
