  • Patent number: 5798095
    Abstract: The hair treatment composition is free of anionic surfactant, has a pH of from 2 to 7 and includes a combination of 0.5 to 15 percent by weight of a surfactant component A) consisting of at least one water-soluble cationic surfactant and/or at least one water-soluble amphoteric surfactant and 0.05 to 5 percent by weight of a component B) consisting of benzoic acid or its physiologically compatible salts or saccharin or its physiologically compatible salts of saccharin with inorganic bases or a mixture of a physiologically compatible salt of saccharin and a physiologically compatible salt of benzoic acid. A weight ratio of surfactant component A) to component B) is from 2:1 to 1:10. A room-temperature method of making the hair treatment composition is also described.
