19 Claims

1. A composition comprising, in a physiologically acceptable medium:

a. water;

b. at least one cellulosic cationic polymer (CP);

c. at least one anionic polymer (AP) chosen from methacrylic acid homopolymer salts;

d. at least one anionic surfactant comprising at least one cationic counterion;
