  • Patent number: 7928048
    Abstract: A softening detergent composition containing (a) 1 to 30% by mass of a clay mineral; (b) 0.5 to 20% by mass of a compound capable of releasing hydrogen peroxide in water; (c) 0.1 to 20% by mass of a compound represented by the following general formula (I) or (II): wherein R1 is an alkyl alkyl group having 4 to 13 carbon atoms; R2 is an alkyl group having 5 to 13 carbon atoms; M is hydrogen atom, or alkali metal atom, alkaline earth metal atom, ammonium or alkanolamine, or a combination of both; and 10 to 60% by mass of a component corresponding to a surfactant as prescribed in JIS K 3362:1998, wherein a mass ratio of the component (b) to the component (c) [component (b)/component (c)] is from 3/4 to 20/1. The softening detergent composition is suitably used as a softening detergent for fibrous manufactured articles such as clothes.

  • Patent number: 6372704
    Abstract: The present invention provides a detergent composition which is excellent in enzyme stability and exhibits excellent detergency particularly to protein-related dirt of socks and other items even under laundering conditions at a lower temperature. That is, the present invention provides a detergent composition comprising specific proportions of (a) an anionic surfactant, (b) a chlorine scavenger, (c) a protease whose &agr;-keratin-hydrolyzing activity at 10° C. is not less than 0.09×10−3 &mgr;g/mPU·min and (d) a protease whose &agr;-keratin-hydrolyzing activity at 10° C. is less than 0.09×10−3 &mgr;g/mPU·min.
