  • Patent number: 5532023
    Abstract: The present invention relates to a wrinkle reducing composition for use on fabrics, particularly clothing. The composition comprises a wrinkle reducing active, which is made up of an effective amount of silicone and an effective amount of film-forming polymer, and a liquid carrier. The composition is substantially free of starch, modified starch, and mixtures thereof, and results a Loss Modulus Difference of greater than about 3.3.times.10.sup.7 Pascal on fabric.The composition can be incorporated into a spray dispenser that can create an article of manufacture than can facilitate treatment of fabric with the wrinkle reducing composition. The wrinkle reducing actives in the composition can be determined through Dynamic Mechanical Analysis using a 100% cotton broadcloth swatch and a fixed volume of a sample of wrinkle reducing active.

  • Patent number: 5500138
    Abstract: The present invention relates to liquid and solid biodegradable fabric softener compositions combined with highly enduring substantive perfumes. These compositions are naturally, or synthetically, derived perfumes which are hydrophobic, defined by having a low rinse water solubility (ClogP is greater than or equal to 3.0). These perfumes also have low volatility, a boiling point of 250.degree. C., or greater. These compositions provide better perfume deposition on treated fabric, and consequently are not substantially lost during the rinse and drying cycle for less impact on the environment. Also, these perfumes improve the physical stability of the softener composition.

  • Patent number: 5498373
    Abstract: Amine oxide surfactants contaminated with nitrite are treated under acidic conditions with materials such as maleic acid and diethylenetriaminepentaacetate (DTPA) to reduce nitrite levels below 1 ppm. Thus, C.sub.12-13 dimethyl amine is oxidized with hydrogen peroxide in the presence of maleic acid and DTPA to reduce nitrite levels. The resulting nitrite-free amine oxide is employed in various detergent compositions.
