  • Patent number: 7186275
    Abstract: The present invention relates to hair care compositions comprising an oxidizing agent and chelants having log ? ? K CuL log ? ? K CaL ratio calculated at pH 10 of at least 3.20 wherein log KCuL is the common logarithm of the Conditional Stability Constant of said chelant with Cu2+ and log KCaL is the common logarithm of the Conditional Stability Constant of said chelant with Ca2+. Suitable chelants are diamine-N,N?-dipolyacids or monoamine monoamide-N,N?-dipolyacids. The compositions according to the present invention contribute to reducing the oxidative damage sustained by a keratinous fiber such as hair during bleaching, dyeing, perming or other oxidative treatments. Especially preferred diamine dipolyacid is ethylenediamine-N,N?-disuccinic acid (EDDS).

  • Patent number: 6559113
    Abstract: Detergent compositions comprise a water-soluble builder, an enzyme and a polymeric dye transfer inhibiting agent, wherein a means is provided for delaying the release of the enzyme relative to the release of the water-soluble builder to the wash solution. The time to achieve a concentration that is 50% of the ultimate concentration of the water-soluble builder is less than 60 seconds, and the time to achieve a concentration that is 50% of the ultimate concentration of the enzyme is more than 90 seconds.
