Abstract
The subject of the present disclosure is agents for oxidative hair dyeing containing from about 65-about 83 wt. % water, oxidation dye precursor(s), alkalizing agent and a specific mixture of a crosslinked copolymer of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30-monoalcohols, glyceryl fatty acid esters, selected from fatty alcohol ethoxylated and linear, saturated C8-C22-alkan-1-ol, wherein the dye obtains the optimal viscosity for application and the consistency of a gel-like cream with outstanding haptics.
Claims20
Agent for oxidative hair dyeing comprising, relative to the weight of the agent,
- from about 65 to about 83 wt. % water,
- at least one oxidation dye precursor,
- at least one alkalizing agent,
- at least one crosslinked copolymer comprising acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30-monoalcohols as monomers, wherein the crosslinked copolymer is included in a total amount of from about 0.1 to about 0.8 wt. %,
- at least one linear, saturated 1-alkanol with a hydroxy group and from about 8 to about 22 carbon atoms in a total amount of from about 3 to about 7 wt. %,
- in a total amount of from about 0.2 to about 2 wt. %, at least one glyceryl fatty acid ester having the formula (I)
- wherein
- R1, R2 and R3 denote a hydrogen atom or a methyl group independent of each other or a grouping of Formula (II),
- wherein
- R4 denotes an unbranched or branched, saturated or unsaturated C11-C27-alkyl group,
- providing that at least one and a maximum of two of the radicals, selected from R1, R2, and R3, denotes a grouping of Formula (II);
- at least one linear, saturated ethoxylated 1-alkanol with from about 8 to about 22 carbon atoms in the alkyl radical and degree of ethoxylation of from about 80 to about 120 in a total amount of from about 0.1 to about 2 wt. %, and
- at least one linear, saturated ethoxylated 1-alkanol with from about 8 to about 22 carbon atoms in the alkyl radical and degree of ethoxylation of from about 20 to about 50, in a total amount of from about 0.1 to about 2 wt. %,
- wherein no oxidants are included;
- and
- wherein the agent has a viscosity of from about 30,000 to about 35,000 mPas, measured at 22° C. by employing a Brookfield rotational viscometer at a rotational frequency of 4 rpm with Spindle TC.
Agent for oxidative hair dyeing comprising, relative to the weight of the agent,
