  • Publication number: 20050164903
    Abstract: The present invention relates to a mixed surfactant system, and particularly to a mixed surfactant system which comprises an anionic surfactant and a compound comprising at least one kind of non-ionic group or cationic group, and which thus increases cleaning power of the anionic surfactant, increases stability to hard water, lowers surface tension and cmc, and can control initial foamability and foam stability by the mixing ratio of the non-ionic surfactant and the cationic surfactant that can be added together, and that is therefore very useful for a detergent of solid, liquid, gel, or paste types.
