  • Patent number: 4682982
    Abstract: N-higher alk(en)yl neoalkanamides are new compounds which unlike many other amides, are oily at washing temperatures, in the 10.degree. to 90.degree. C. range, and are capable of being adsorbed from wash and rinse waters by fibrous materials, such as laundry of synthetic, e.g., polyester, fabrics, which laundry is susceptible to being electrostatically charged, and decrease any electrostatic charge or inhibit accumulation thereof on such materials. Such neoalkanamides, e.g., N-coco-alkyl neodecanamide, can be incorporated in detergent compositions and in compositions for addition to laundry rinse waters, and in some instances it may be desirable for bentonite powder or agglomerate to also be included in such compositions to contribute fabric softening and other useful physical properties. Washing and rinsing operations are described in which N-higher alk(en)yl neoalkanamide is present in the waters, with and without supplementing small proportions of quaternary ammonium salt.

  • Patent number: 4678594
    Abstract: Granular detergent additives contain finely divided powders of both acyloxybenzene sulfonate (AOBS), e.g. nonanoyloxybenzene sulfonate, bleach activator and an oxygen containing bleach, e.g. sodium perborate, encapsulated in a water soluble organic binder, especially a nonionic ethoxylated alcohol surfactant. The bleach and bleach activator do not react with each other until the granules are added to water at which time the reaction is substantially instantaneous and complete due to the close proximity of the reactants to each other. The granular detergent additives can be used alone or as a component of a full detergent composition to provide storage stable, low temperature effective bleaching activity.

  • Patent number: 4668398
    Abstract: A continuous extraction apparatus and a continuous extraction process for extracting an extractable component of a liquid or particulate feed material with an immiscible liquid solvent for the extractable component thereof, which apparatus and process are both especially useful for extracting glycerine from soap, utilize an extraction column with oscillatably movable contact promoting means therein which move in a horizontal plane and have openings therein through which the immiscible feed and the extracting liquid, in different phases, may pass during oscillations, at which time the contact promoting means make repeated contacts with the different phases to renew contact surfaces of the liquids and to bring them into intimate contact with each other, whereby extraction of extractable material from the feed by the extracting liquid is promoted.

  • Patent number: 4664909
    Abstract: A novel fast drying stable pituitous powder suspension in an alcoholic/aqueous medium having a high alcohol content and a low water content, containing hydroxyethyl cellulose as the essential suspending agent, said alcohol content exceeding the upper solubility of hydroxyethyl cellulose in said alcohol and the water content being sufficient to prevent precipitation of said suspending agent and at least 5% by weight; having utility in the preparation of viscous liquid, semi-solid or solid suspension products such as creams or sticks, more specifically, roll-ons or stick deodorants and medicated lotions which may also be pump activated. The alcohol utilized herein is monohydric such as ethanol, methyl or isopropyl alcohol. However, a polyhydric alcohol such as propylene glycol, glycerine and/or polypropylene glycols may be partially substituted for the monohydric alcohol.

  • Patent number: 4663152
    Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to the main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavoring and surface active agents, which may controllably soften the speckles on storage.

  • Patent number: 4661280
    Abstract: A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant in which the stability of the composition is improved by the addition of small amounts of an aluminum salt of higher fatty acid, especially aluminum tristearate. The yield stress of the compositions can be improved with the same or lower plastic viscosity, especially at low concentrations of the aluminum salt. The aluminum salts also exhibit an antifoaming effect and can be used to boost softening.

  • Patent number: 4648983
    Abstract: A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant in which the stability against settling of the composition is improved by the addition of small amounts of urea. The yield stress of the compositions can be improved with the same or lower plastic viscosity, especially at low concentrations of the urea. The addition of small amounts of urea also improves the dispersibility of the suspension of builder salt when the composition is added to water.
