  • Publication number: 20020142935
    Abstract: A kit provides improved use of a consumer product by including a consumer product composition and a hand-held conductivity meter calibrated to the consumer product composition. The hand-held conductivity meter has a user-perceivable indicator which is used to indicate when a consumer product solution formed with the cleaning composition has the appropriate concentration of cleaning composition. A method of use employs the hand-held conductivity meter to measure the conductivity of a consumer product solution.

  • Patent number: 6017865
    Abstract: The present invention relates to detergent compositions comprising: a) a hydrophobic bleaching system selected from i) hydrogen peroxide or a source thereof in amount of from 0.1% to 60% by weight and combined with a hydrophobic peroxyacid bleach precursor in amount of from 0.1% to 60% by weight, ii) a preformed hydrophobic peroxyacid in amount of from 0.1% to 60% by weight, and iii) mixtures of i) and ii), wherein a hydrophobic peroxyacid bleach precursor is defined as a compound which produces under perhydrolysis a hydrophobic peroxyacid whose parent carboxylic acid has a critical micelle concentration less than 0.5 moles/liter measured in aqueous solution at 25.degree. C. and pH 7, and wherein a hydrophobic preformed peroxyacid is defined as a compound whose parent carboxylic acid has a critical micelle concentration less than 0.5 moles/liter measured in aqueous solution at 25.degree. C. and pH 7; b) up to 5% by weight of a perfume composition; and c) at least 0.
