  • Patent number: 7119060
    Abstract: The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, fabric care products, such as fabric softeners, laundry detergents, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention is a solid, substantially spherical particle comprising hydrophobic cationic charge enhancing agents in conjunction with cationic fabric softening agents that assist in adhering the particles onto fabric. The particles can also include a fragrance. The particle can have an average particle diameter of from about 1 micron to about 500 microns. The controlled delivery system of the present invention can be utilized to deliver a broad range of fragrance ingredients onto fabric and prolong fragrance release from the dry laundered fabric over an extended period of time, or yield a high impact fragrance “burst” upon ironing the fabric.

  • Patent number: 6379394
    Abstract: A soil-repellent treatment method for articles based on woven cotton, wherein an amphiphilic soil-repellent agent soluble or dispersible in the treatment medium is deposited on the article during one or more washing, rinsing and/or softening or dying steps, is disclosed. Said soil-repellent agent comprises at least one unit with a function (FAd) capable of being absorbed onto the surface of the cotton by electrostatic interaction; and at least one hydrophobic unit (MH) capayble of configuring said agent at the cotton/water interface. A soil-repellent agent comprising at least one unit with a cationic function (MC) capable of being absorbed onto the surface of the cotton, and the counter-ion thereof, as well as at least one hydrophobic unit (MH) containing at least four carbon atom chemically bonded to the unit having said cationic function (MC) via an oligomeric, polymeric or copolymeric vinyl alcohol chain, is also disclosed.

  • Patent number: 6376456
    Abstract: The present application relates to the inclusion of one or more wrinkle reducing ingredients in a laundry fabric softening product. The benefits are delivered to the laundered item either during the rinse step of the washing procedure or in the dryer. The need for further wrinkle reducing steps when the items are taken from the dryer or after hang drying are thereby reduced.

  • Patent number: 6369025
    Abstract: The present invention discloses an aqueous, concentrated, stable, translucent, or preferably, clear, rinse added liquid fabric softening compositions which provide excellent water dispersibility in rinse water, comprising a fabric softening active and a principal solvent having a ClogP of from about 0.15 to about 0.64, and an asymmetric structure. In order to achieve the main object of the invention, namely excellent water dispersibility, the molar ratio of a principal solvent of a fabric softening active should be not less than 3, preferably from about 3.6 to about 100.

  • Patent number: 6323172
    Abstract: Principal solvents, especially mono-ol and diol principal solvents, having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, are disclosed that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of fabric softener actives having ester linkages in their long, hydrophobic chains. The fabric softener actives are either unsaturated, or have intermediate length chains (˜C12-14) and the said principal solvents are used at levels of less than about 40%. Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.

  • Patent number: 6296670
    Abstract: Rinsing dyed or white fabrics in a chelator-containing rinse bath restores color and brightness. Rinse added compositions comprising chelators such as diethylenetriaminepentaacetate or ethylenediamine disuccinate are used to restore the appearance of colored and white fabrics whose drab appearance has been caused by interactions with metal ions, especially copper and nickel. Compositions comprising the chelators in combination with fabric care auxiliaries such as fabric softeners, cellulase enzymes and chlorine scavengers are provided.

  • Patent number: 6255271
    Abstract: A fabric care composition comprises an amine or amide-epichlorohydrin resin or derivative thereof, a silicone component and, optionally, a textile compatible carrier. The textile compatible carrier facilitates contact between the resin and a fabric. The composition is adapted for use in the rinse cycle of a laundering process and may be used, as part of such a process, in the treatment of fabric to reduce creasing of the fabric.

  • Patent number: 6093691
    Abstract: The present invention relates to a fragrance delivery system for use in laundry detergent compositions which provides a long lasting "freshness" or "clean" scent to fabric. The compositions described herein deliver highly fabric substantive pro-accords to the fabric surface during laundering wherein the pro-accords release their fragrance raw materials over a period of up to two weeks. The present invention also relates a method for delivering a pleasurable scent to fabric which has a lasting freshness quality by contacting the fabric with a laundry detergent composition which comprises the fragrance-releasable pro-accords.
