  • STABLE LIQUID CLEANSING COMPOSITIONS WHICH MAY BE PREPARED USING BROAD SELECTION OF FATTY ACYL ISETHIONATE SURFACTANTS
    Publication number: 20080153729
    Abstract: The invention provides liquid cleanser compositions which can use fatty acyl isethionates mixtures, regardless of free fatty acid content of isethionates mixture or chain length distribution of isethionates mixture. The key is to ensure a specific combination of liquid crystal inducer (of surfactant phase) and of modifier so that the isethionates will be stable at low and high temperatures.
