Cosmetic composition in the form of a water-in-oil emulsion for treating hair to improve combing

A cosmetic composition (C1) in the form of a water-in-oil emulsion comprising, per 100% of mass:

• from 60% to 95% by mass of a gelled aqueous phase (A1) comprising at least one crosslinked cationic polyelectrolyte which comprises a proportion of greater than or equal to 5 mol % of monomer units derived from an element from the group consisting of 2, N,N,N-tetramethyl-2-[(1-oxo-2-propenyl)amino]propanammonium chloride (AMP TAC), 2, N, N-trimethyl-2-[(1-oxo-2-propenyl)amino]propanammonium chloride and N,N,N-trimethyl-3-[(1-oxo-2-propenyl)amino]propanammonium chloride (APTAC),
• from 5% to 40% by mass of a fatty phase (A2) comprising at least one oil and an emulsifying system comprising at least one emulsifying surfactant(S) selected from the elements of the group consisting of compositions of alkylpolyglycosides, and compositions of alkylpolyglycosides and of fatty alcohols, polyglycerol esters, alkoxylated polyglycerol esters, polyglycol polyhydroxystearates, polyglycerol polyhydroxystearates, and alkoxylated polyglycerol polyhydroxystearates,
• wherein the crosslinked cationic polyelectrolyte (CP) comprises, per 100 mol %:
• a1) from 5 mol % to 60 mol % of monomer units derived N,N,N-trimethyl-3-[(1-oxo-2-propenyl)amino]propanammonium chloride (APTAC);
• a2) from 0.1 mol % to 5 mol % of monomer units derived from tetraethoxylated lauryl methacrylate;
• a3) from 35 mol % to 94.9 mol % of monomer units derived from 2-hydroxyethyl acrylate;
• a4) a proportion of greater than 0 mol % and less than or equal to 1 mol % of monomer units derived from at least one diethylenic or polyethylenic crosslinking monomer (AR);
• the sum of said molar proportions of monomer units according to a1), a2), a3) and a4) being equal to 100 mol %.
