[0140] The measurements were conducted in each case on 10 hair strands in an automated system for determining the wet combability.

[0141] The hair strands (12 cm/1 g) from HIP were pretreated in an automated hair treatment system according to the following steps: [0142] 30 min cleansing with 6% sodium lauryl ether sulfate, pH 6.5, then intensive rinsing of the hair, [0143] 20 min bleaching with a 5% hydrogen peroxide solution, pH 9.4 (adjusted with ammonium hydroxide solution), then intensive rinsing of the hair, [0144] 30 min drying in a stream of air at 68° C.

[0145] Directly prior to the blank measurement, the hair was swollen for 30 minutes in water and then rinsed for 1 minute in an automatic wet combing machine. In the automated system for determining the wet and dry combability, the combing forces were determined during 20 combings and the combability calculated by integrating the force-displacement curves measured. After the blank measurement, the hair was immediately treated with the formulation (0.25 g/g of hair). After 5 minutes contact time, the hair was rinsed with the automatic wet combing machine under standard conditions (38° C., 1 l/minute). The treatment and subsequent rinsing was repeated a second time. The comparative measurement (to the blank measurement) was then carried out. The measurements were conducted using the fine comb side of the natural rubber comb. The remaining combability per strand was calculated as follows:

remaining combability=combability before product treatment/combability after product treatment [0146] The remaining combability is the “WC %” value.

[0147] From the quotients of all 10 strands, the average and standard deviation was then determined.

[0148] From the above examples, the following conclusions could be drawn. Formulation −08 showed a significantly better WC compared to formulation −04. Further improvement of the wet combability could be achieved by using the thickener Arlypon® TT liquid (formulation −07). At the same time, the viscosity-reducing effect of the solubilizers could be canceled out.

[0149] The combination of the hydrophilic solubilizers plus thickeners which has been found to be advantageous was formulated into a product, the “hydrophilic conditioning compound”. A small amount of water was added to the product for clarification. This compound was composed as follows:

[0150] composition of the “hydrophilic conditioning compound” (INCI nomenclature):

[0151] 55.6% Eumulgin® CO 40: hydrogenated Castor Oil+40 mol EO

[0152] 27.8% Cetiol® HE: Coco, Mono- and Diglycerides+7 mol EO

[0153] 8.3% Arlypon® TT liquid: Trimethylolpropane+120 EO/10 PO−Random−Trioleate

[0154] 8.3% demineralized water

[0155] The conditioning effect (WC improvement) of the hydrophilic compounds could also be demonstrated when using further conditioning polymers in clear and pearlescent systems. The examples are shown in the following table (composition in % by weight).

[0156] Formulation −23 showed a considerable improvement in the wet combability in the case of particularly highly damaged hair (bleached 3 times). The WC of formulation −23 was 52% (+−4%) compared to the placebo formulation without the hydrophilic compound 101% (+−12%).

[0157] DC signifies dry combability. The comparison shows a significantly better value for example 23 compared to example 1.

[0158] Also variations in the composition of the hydrophilic conditioning compound showed similar results in the improvement in combability. The examples are shown in the following table (composition in % by weight).

[0159] In experiments on the microbial stability of the intermediate (hydrophilic conditioning compound) , a water content of 8.3% was found to be high in terms of water activity. In one variation, therefore, some of the water was replaced by glycerol. In this case, the 8.3% water was reduced to 4.3% water and 4% glycerol was added, whereby the water activity was reduced to within a microbially harmless range.

[0160] A modification to the advantageous properties of the intermediate with regard to its contribution to the conditioning effect of compositions produced therefrom by the partial exchange of water for glycerol is not to be expected.

[0161] A possible composition of the compound is therefore:

[0162] Eumulgin® CO 40 (55.6%): hydrogenated Castor Oil+40 mol EO

[0163] Cetiol® HE (27.8%): Coco, Mono- and Diglycerides+7 mol EO

[0164] Arlypon® TT liquid (8.3%): Trimethylolpropane+120 EO/10 PO−Random−Trioleate

[0165] Demineralized water (4.3%)

[0166] Glycerol (4.0%)

Further Examples

[0167] A feature of the composition according to the invention is the presence of NaCl. This ensures that the coacervate mechanism of anionic surfactant and cationic polymer is initiated in the dilution phase. In this case, the NaCl can be entrained with the cosurfactant (cocamidopropylbetaine for example which often, by virtue of the production process, often already comprises ca. 5-7.5% by weight NaCl) and/or can be added separately. The two examples which follow show a statistically relevant improvement in the wet combability as a function of the use of NaCl:
