Hair restructuring association comprising a quaternary ammonium salt and a sulpho-derivative of vegetable fatty acids

Cosmetic formulation in the form of a hair conditioning product comprising a hair restructuring association comprising:

• (a) a quaternary ammonium salt of formula (I),
• (b) at least one sulpho-derivative of vegetable fatty acids, in combination with suitable excipients and/or diluents,
• wherein:
• (i) in formula (I):
• R1 is H, R2, R3 and R4 are methyl;
• R5, R6 are independently chosen between hydrogen and a radical R0, wherein the radical R0 consists of the following structure of formula (II),
• the counteranion mX− is that of malic acid,
• m is an integer number between 1 and 22, n is between 2 and 20;
• (ii) the sulpho-derivative of vegetable fatty acids (b) is a sulphated derivative obtained by sulphation of castor oil;
• (iii) the salt (a) of formula (I) is contained in amounts less than 20% by weight on the weight of the sulphoderivative (b);
• (iv) the restructuring association is in a concentration between 4% and 75% (w/w) on the total weight of said composition.
