In a wax based cosmetic composition containing a polymer and from about 5 to 40% by weight of a wax selected from the group consisting of vegetable, animal, mineral and synthetic wax, said wax having a melting point of 60 to 110 degrees C., and a needle penetration according to ASTM Method D5 at 25 degrees C. of 3 to 40 and said wax being solid and rigid at a temperature below 50 degrees C., wherein the improvement comprises said polymer being the combination of a cationic polymer and an anionic polymer, said cationic polymer being present in the cosmetic composition in an amount of about 0.1 to 10% by weight and having a molecular weight of 1,000 to 3,000,000, said cationic polymer being a polymer of the polyamine, polyamino-polyamide or poly-(quaternary ammonium) type, the amine or ammonium group forming a part of or being joined to the polymer chain, said anionic polymer being present in the cosmetic composition in an amount of about 0.1 to 10% by weight and having a molecular weight of 500 to 3,000,000, said anionic polymer containing carboxylic, sulphonic or phosphoric acid groups.
In a wax based cosmetic composition containing a polymer and from about 2 to 40% by weight of a wax selected from the group consisting of vegetable, animal, mineral and synthetic wax, said wax having a melting point of 60 to 110 degrees C., and a needle penetration according to ASTM Method D5 at 25 degrees C. of 3 to 40 and said wax being solid and rigid at a temperature below 50 degrees C., wherein the improvement comprises said polymer being the combination of a cationic polymer and an amphoteric polymer, said cationic polymer being present in the cosmetic composition in an amount of about 0.1 to 10% by weight and having a molecular weight of 1,000 to 3,000,000, said cationic polymer being a polymer of the polyamine, polyamino-polyamide or poly-(quaternary ammonium) type, the amine or ammonium group forming a part of or being joined to the polymer chain, said amphoteric polymer being present in the cosmetic composition in an amount of about 0.1 to 10% by weight.
