  • Liquid cleansing composition
    Publication number: 20070027050
    Abstract: A mild, aqueous, liquid crystalline structured cleansing and moisturizing composition with low levels of surfactants that include monoalkyl sulfosuccinate surfactant(s) and high levels of hydrophillic emollients is provided that provides a low in-use slip, tight skin feel, and a fast, clean-feel rinse in the absence of substantial levels of soap. Substantial amounts of persistent and fine quality lather are produced with the inventive composition even in the presence of high levels of emollients.

  • Liquid composition with enhanced low temperature stability
    Patent number: 6174846
    Abstract: The invention relates to liquid cleansing compositions in lamellar phase. Use of minimum amounts of defined polymeric hydrophilic emulsifier in combination with a lamellar phase inducing structurant has been found to enhance both initial viscosity and free thaw (low temperature) viscosity/stability.

  • Liquid cleansing composition comprising soluble, lamellar phase inducing structurant and method thereof
    Patent number: 5952286
    Abstract: The present invention relates to lamellar phase compositions comprising defined surfactant systems and a structurant selected from the group consisting of liquid fatty acids liquid alcohols and derivatives thereof which structurant is responsible for inducing the lamellar phrase. The invention also relates to a method of inducing said lamellar phase in such compositions by adding the defined structurant.

  • Personal cleansing system comprising polymeric diamond-mesh bath sponge and liquid cleanser with deodorant composition
    Patent number: 5916586
    Abstract: In one embodiment the present invention relates to a personal bath or shower gel system comprising (A) a light weight polymeric meshed sponge and (B) a liquid cleanser comprising (1) an effective amount of surfactants(s) and (2) a deodorant perfume. In a second embodiment, the invention relates to a method for enhancing delivery/dispersion of deodorant perfume on skin or substrate by either applying liquid to sponge and applying sponge to substrate and/or applying liquid to skin/substrate and then rubbing skin/substrate with said sponge.

  • Mild antimicrobial liquid cleansing formulations comprising buffering compound or compounds as potentiator of antimicrobial effectiveness
    Patent number: 5681802
    Abstract: A liquid skin cleansing composition comprises (1) mild surfactant systems; (2) 0.1 to 10% by wt. of a compound or compounds which buffer the pH of the composition; and (3) 1% to 99% water to potentiate the bactericidal activity. In a second embodiment of the invention, the buffering compound or compounds potentiates antibacterial effect in compositions already containing an antibacterial agent.

  • Method for detecting detergent compositions for enhanced silicone deposition comprising silicone and cationic polymers
    Patent number: 5422280
    Abstract: This invention involves a method for determining silicone deposition enhancing cationic polymers to be formulated into silicone-containing formulations which comprises the steps of preparing a composition having an anionic surfactant, an amphoteric surfactant, silicone, and a cationic polymer, diluting that composition, and making a positive determination if flocculation occurs within three days.
