  • Mild skin cleansing soap bar with hydrated cationic polymer skin conditioner
    Patent number: 5064555
    Abstract: Disclosed is a mild skin cleansing soap bar composition comprising: (1) 50-90% soap, and (2) a hydrated cationic polymeric skin conditioner. The physical composition of the bar is such that the hydrated polymer is substantially uniformly distributed and well incorporated in the soap. The hydrated cationic polymer improves the mildness of the soap bar to a level approaching that of bars made with very mild synthetic surfactants, while maintaining the desirable physical characteristics of a pure soap bar without the polymer.The preferred polymer is a hydrated cationic guar gum having a typical aqueous viscosity at 1% of from about 125 cps to about 3500.+-.500 cps.

  • Jumbo particulate fabric softner composition
    Patent number: 5002681
    Abstract: A pouched, detergent-compatible, through-the-wash, dryer-released, jumbo particulate fabric softening composition. The particle size of this particulate is from about 5 mm to about 30 mm, and preferably at least 10 mm. The low viscoisty jumbo particulate fabric softener is made to survive the wash more so than comparable smaller particulates and release more in the dryer than higher viscosity softener. The softener particulate of this invention has a low viscosity at about its melting point for good softener transferability from the pouch to the fabric, superior release in the dryer, and reduced residual pouch staining.
