Synergistic combination of cationic and ampholytic polymers for cleansing and/or conditioning keratin based substrates

A conditioning composition comprising:

• (a) about 5% to about 50%, by weight, of a surfactant component selected from the group consisting of anionic surfactants, amphoteric surfactants, cationic surfactants, nonionic surfactants, and zwitterionic surfactants;
• (b) about 0.05% to about 10%, by weight;
• of a water soluble, organic, ampholytic polymer conditioning agent
• (c) about 0.05% to about 10%, by weight, of a water soluble, organic, cationic polymer conditioning agent;
• (d) zero to about 70%, by weight, of a water insoluble liguid;
• and
• (e) an aqueous carrier
• wherein said water soluble, organic ampholytic polymer conditioning agent of (b) is comprised of:
• (A) about 1 to about 99 mol % of at least one monomer selected from the group consisting of alkyl acrylamidopropyl-dimethyl ammonium halides, alkyl methacrylamidopropyldimethyl ammonium halides, alkyl acryloyloxyethyl dimethyl ammonium halides, alkyl methacryloyloxyethyl dimethyl ammonium halides, and dialkyl diallyl ammonium halides;
• (B) about 1 to about 99 mol % of at least one monomer selected from the group consisting of acrylic acid (AA), methacrylic acid (MAA), 2-acrylamido-2-methylpropane sulfonic acid (AMPSA) 2-methacrylamido-2-methylpropane sulfonic acid (MAMPSA), n-methacrylamidopropyl,n,n-dimethyl,amino acetic acid, n-acrylamidopropyl,n, n-dimethyl,amino acetic acid, n-methacryloyloxyethyl,n,n-dimethyl,amino acetic acid, and n-acryloyloxyethyl,n,n-dimethyl,amino acetic acid;
• and
• (C) about 0 to about 80 mol % of at least one monomer selected from the group consisting of C1-C22 straight or branched chain alkyl acrylate or methacrylate, a C1-C22 straight or branched chain n-alkyl acrylamide or methacrylamide, acrylamide methylacrylamide, n-vinylpyrrolidone, vinyl acetate or ethoxylated and propoxylated acrylate or methacrylate;
• with a weight average molecular weight of, as determined by viscometry, from about 100,000, to about 10,000,000
• wherein the mol ratio of (A):(B) in said water soluble, organic ampholytic polymer conditioning agent ranges from about 25:75 to about 75:25.
