Abstract
Abstract A conditioning shampoo containing an anionic surfactant, in an amount of about 5% to about 25% by weight, and a cationic acrylate/acrylamide copolymer conditioning agent material, in an amount of about 0.1% to about 20% by weight, has extended product stability, excellent overall conditioning to human hair, particularly superior wet and dry combing properties, and unexpectedly maintains very high levels of foam, with a mild anionic cleansing detergent, e.g., an anionic carboxylate detergent, or with lower amounts of a strong anionic cleansing detergent, such as a long chain (C 12 -C 22 ) alkyl sulfate, and/or a long chain (C 12 -C 22 ) partially or fully ethoxylated alkyl sulfate; and/or a long chain (C 12 -C 22 ) sulfonate.
