  • Patent number: 4758376
    Abstract: The detergent compositions of the present invention comprising a phosphate surfactant and an amidoamine amphoteric surfactant; a hydroxysulfobetaine, aliphatic lactylate, or aliphatic glycolate, have excellent foam characteristics such as foaming property, foaming power, and rapidity of foaming, as well as excellent low-temperature stability, detergency, and mildness to the skin and hair. Therefore, these compositions can be effectively employed for shampoos and cleaning agents for infants which require not only good detergency but also a low incidence of skin irritation.
