  • Publication number: 20160060582
    Abstract: The present invention relates to a method of laundering fabric using a laundry washing liquor containing a relatively low Through-The-Wash (TTW) dosage of a diphenyl ether anti-microbial agent. Such relatively low TTW ranges from about 0.25 to about 1 ppm, but it surprisingly and unexpectedly exhibits antimicrobial effect that is comparable with higher TTW dosage. The present invention also relates to anti-microbial laundry detergent compositions designed for delivering, or laundry washing liquors that contain, such a low TTW dosage of the diphenyl ether anti-microbial agent.

  • Publication number: 20050201971
    Abstract: The present invention is directed to a method for advertising a deodorizer. The method has the steps of using a color indicator and a color change reaction caused by the color indicator; and visualizing the malodor removal performance of the product by the color change. The advertising method also has the steps of preparing a promotion product and a comparative product; preparing at least two separate closed spaces; and then, in any order: placing the promotion product inside one of the closed spaces; placing a material inside each closed space, wherein the material comprises a color indicator; adding a malodor substance to each of the closed spaces to thereby cause a color change to the color indicator. Finally, the last step is that of showing the difference of the material color between the promotion product and the comparative product. These steps are visually recorded to form an advertisement and wherein the advertisement is transferred electronically.
