Aqueous conditioning cosmetic composition, cosmetic products, method of repair and protection of hair properties, and, use of a cosmetic product

An aqueous conditioning cosmetic composition for hair, characterized by comprising:

• at least one non-ionic surfactant comprising ethoxylated fatty alcohols having structure compatible with formula (I), wherein a and b, respectively, ranges from 6 to 24 carbon atoms and ranges from 20 to 100 units of ethylene oxide
• and
• at least one cationic polymer which belongs to the polyquaterniums class of structure compatible with the formulas (II) and (III) wherein n corresponds to the range of 725 to 4,600 repeating units, being n large enough for the aqueous solution of 2% of this polymer to have viscosity between 200 and 900 mPa·s and molar mass between 250 and 900 kDa;
• x and y correspond, respectively, to the ranges of 3,000 to 18,500 and of 750 to 5,000 repetition units, being x and y large enough so that the polymer has molar mass between 10,000 and 60,000 kDa,
• wherein the formula (II) consists of R1, R2 e R3 independently chosen between the groups —H and —(CH2CH2O)mQ, wherein m corresponds to the range of 1 to 5 units of ethylene oxide and Q is a cationic group of structure compatible with the Formula (IV), so that the charge density and nitrogen content are in the range of 0.8% to 2.2%
• wherein the at least one non-ionic surfactant and the at least one cationic polymer are combined with each other in a ratio between their totalities from 99:1 to 80:20 by weight, and
• wherein the composition is free of silicones, including aminated silicones.
