Emulsifying composition with cationic nature

A composition (C1) comprising, per 100 mol %:

• (a)—from 0.1 mol % to 5 mol % either of a compound of formula (I):
• in which formula (I) each of the Z radicals represents, independently of one another, a hydrogen atom or a monovalent radical (Z1):
• in which the X− anion represents an anion chosen from the bromide ion, the chloride ion, the iodide ion, the para-toluenesulfonate ion, the methanesulfonate ion or the trifluoromethanesulfonate ion;
• wherein at least one of the Z radicals does not represent a hydrogen atom;
• in which formula (I) the R2 radical represents a linear or branched alkyl radical comprising from 8 to 22 carbon atoms and in which formula (I) m represents a number greater than or equal to 1 and less than or equal to 5;
• or of a mixture of compounds represented by said formula (I);
• (b)—from 30 mol % to 60 mol % either of a compound of formula (IV):
• in which formula (IV) the X− anion is as defined for said radical (Z1) and the R2 radical is as defined for said formula (I);
• or of a mixture of compounds represented by said formula (IV);
• (c)—from 5 mol % to 15 mol % of a compound of formula (V):
• in which formula (V) the X− anion is as defined for said radical (Z1);
• (d)—from 15 mol % to 30 mol % of a compound of formula (VI):
• in which formula (VI) the X− anion is as defined for said radical (Z1) and the R1 radical represents a linear or branched alkyl radical comprising from 1 to 6 carbon atoms.
