  • Patent number: 8067350
    Abstract: A cleansing composition is disclosed that changes color during use. The cleansing composition contains a plurality of thermochromic dyes that cause a color change to occur at a threshold temperature and continue to cause a color change over a temperature range. The range of temperatures corresponds to approximately the amount of time sufficient to properly wash or scrub using the product.

  • Patent number: 7642395
    Abstract: The present invention provides a topical composition for application to the perianal and/or labial areas of the skin which helps prevent viscoelastic fluids, such as menses and feces, from attaching to the skin and aids in the reducing the viscoelastic properties of the fluid so that the fluid can flow into absorbent articles. The composition contains at least one viscoelastant material and at least one an anti-adherent material. the composition may be applied with a wipe, including mitts and gloves, a solid stick composition, an aerosol dispenser, a pump spray, a trigger spray, a squeeze bottle, as a foam, as a cream, as an ointment, as a salve, as a gel, as a wash or as a lotion. In addition, absorbent articles, such as pads or pants, diapers and the like may also be used as a means to transfer the composition to the skin.

  • Patent number: 6610314
    Abstract: Antimicrobial formulations, which may be essentially free of an antimicrobial active, comprising one or more proton donating agents and an alkyl phosphate anionic surfactant comprising a mono alkyl phosphate having the chemical structure: wherein R1 is a saturated or unsaturated straight chain or branched alkyl group having from about 8 to about 22 carbon atoms, x is a number from 0 to about 20, and R2 and R3 are independently selected from hydrogen, an alkali metal, or an alkanol amine, are provided and described herein. The formulations may be incorporated into wet wipes or various other personal care items such as facial tissue, bathroom tissue or feminine care products, or may be incorporated into lotions or soaps which may be applied directly to the skin. The antimicrobial formulations of the present invention have been found to have surprisingly high activity against numerous bacteria and other microorganisms.
