Abstract
A cosmetic agent for dyeing keratin fibers, in particular human hair, includes at least one special non-ionic linear silicone polymer and at least one oxidation dye pre product and/or a direct dye. The use of the at least one non-ionic linear silicone polymer leads to an improved colorfulness and/or depth of shades. A corresponding packaging unit (kit of parts) and a method for dyeing keratin fibers both include the cosmetic agent. The cosmetic agent and packaging unit including the same are used for increasing the colorfulness and/or depth of shades.
Claims7
A cosmetic agent for changing the color of keratinic fibers, comprising in a cosmetically acceptable carrier:
- at least one compound, selected from the group of oxidation dye precursors, direct dyes, and mixtures thereof;
- a first linear nonionic silicone polymer (SP1) has the formula (II),
- wherein
- R2 and R7, in each case independently of one another, stand for a methyl group or a hydroxyl group, and
- x stands for integers from 1,650 to 8,500;
- and
- a second linear nonionic silicone polymer (SP2) has the formula
- wherein
- R2 and R7, in each case independently of one another, stand for a methyl group or a hydroxyl group, and
- y stands for integers from 40 to 1300,
- wherein the first and second linear nonionic silicone polymers have no carboxylic acid groups or amine groups, are included in the form of an emulsion, wherein the emulsion has particles with an average particle diameter D50 of 0.01 μm to 100 μm, and
- wherein in the claimed formulae (II) and/or (III), R2 and R7 do not both stand for a methyl group.
