Hair care compositions comprising cationic compounds, starch, and silane compounds

A translucent rinse-off composition for conditioning hair, the composition comprising:

• (a) from about 1.5% to about 8% by weight of a cationic agent comprising:
• (i) a first quaternary ammonium compound, including its salts, of the general formula (I):
• wherein R1 and R4, may independently be chosen from saturated or unsaturated, linear or branched, aliphatic hydrocarbon radicals comprising from 1 to about 30 carbon atoms, or an alkoxy, alkoxycarbonylalkyl, polyoxyalkylene, alkylamido, alkylamidoalkyl, hydroxyalkyl, aromatic, aryl or alkylaryl radical comprising from about 12 to about 30 carbon atoms, with at least one radical among R1, R2, R3 and R4 denoting a radical comprising from 8 to 30 carbon atom;
• and X″″ is chosen from halides, phosphates, acetates, lactates, (C2-C6) alkyl sulfates, and alkyl- or alkylaryl-sulfonates;
• and
• (ii) a second quaternary ammonium compound, including its salts, chosen from quaternary ammonium compounds of imidazoline of the general formula (II):
• wherein R5 and R6 are chosen from alkenyl and alkyl radicals comprising from 8 to 30 carbon atoms or alkenyl and alkyl radicals derived from palm oil or hydrogenated tallow;
• R6 is chosen from hydrogen, C1-C4 alkyl radicals, and alkenyl and alkyl radicals comprising from 8 to 30 carbon atoms;
• R7 is chosen from C1-C4 alkyl radicals;
• R8 is chosen from hydrogen and C1-C4 alkyl radicals;
• and X″ is chosen from halides, phosphates, acetates, lactates, alkyl sulfates, alkyl sulfonates, and alkylaryl sulfonates;
• (b) from about 3.5% to about 8% by weight of at least one modified starch;
• (c) from about 0.1% to about 4% by weight of a first silane compound corresponding to formula (Ib):
• R1Si(OR2)z(R3)x(OH)y (Ib)
• in which:
• R1 is a cyclic or acyclic, linear or branched, saturated or unsaturated C1-C22, in particular C2-C20, hydrocarbon-based chain, which may be substituted with a group chosen from amine groups NH2 or NHR (R being a linear or branched C1-C20, in particular C1-C6, alkyl, a C3-C40 cycloalkyl or a C6-C30 aromatic radical);
• the hydroxyl group (OH), a thiol group, an aryl group (more particularly benzyl), which is possibly substituted with an NH2 or NHR group;
• it being possible for R1 to be interrupted with a heteroatom (O, S or NH) or a carbonyl group (CO),
• R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms,
• y denotes an integer ranging from 0 to 3, and
• z denotes an integer ranging from 0 to 3, and
• x denotes an integer ranging from 0 to 2, with z+x+y=3;
• (d) from about 0.1% to about 1.5% by weight of a second silane compound chosen from amino silicones;
• (e) from about 0.075% to about 4% by weight of a cationic vinylpyrrolidone polymer chosen from polyquaternium-11;
• and
• (f) water;
• wherein when the composition contains a fatty alcohol, the fatty alcohol is present in an amount not more than 1% by weight of, based on the total weight of the composition;
• and
• all weights being based on the total weight of the composition.
