  • Patent number: 4590065
    Abstract: A dentifrice composition that reduces the migration/absorption of flavor into plastic packaging materials, containing a flavor oil in combination with about 5.0%-50.0% and preferably 12.0% by weight of the total flavor oils of polyvinyl pyrrolidone (PVP), dispersed in a dental vehicle. The dentifrice composition may be in the form of a paste, cream or gel. It is essential that the flavor oil and PVP be premixed prior to its addition to the dentifrice composition, preferably as a final step in its formulation.

  • Patent number: 4585447
    Abstract: A disposable diaper having elasticized crotch seals and an elasticized waist seal formed from elastic members secured to the backing sheet. The elastic members physically intersect each other and are under such tension so as to provide an initial stretching of the elastic members extending substantially at right angles to each other thereby maximizing the comfort of an infant wearing the disposable diaper while maintaining a boat-like shape before application on an infant with the ears in a raised position. The elastic members may be spaced from the edge of the pad or may overlie the front or back surface of the pad to minimize leakage.

  • Patent number: 4585449
    Abstract: A disposable product, such as a diaper, sanitary napkin or underpad, provided with a water impervious lower layer, an absorbent pad and a top sheet. The top sheet contains 0.1 to 0.6% by weight of a surfactant. The surfactant may be applied by spraying, printing, roller coating, etc., on the entire surface or, preferably, in limited areas such as in the central areas of the top sheet, or pay be line or spot printed thereon to improve fluid penetration, while retaining optimum fluid wetback and fluid retention characteristics. The top sheet is a hydrophobic sheet of excellent fluid penetration but resists fluid wetback.

  • Patent number: 4584126
    Abstract: Translucent soap cakes, which preferably are transparent, are made from mixed tallow and coconut oil soaps (or equivalents), lanolin soap and/or lanolin fatty acids and/or lanolin and/or other suitable derivative(s) thereof, and mixtures thereof, and water. Soap cakes or tablets of improved translucency (transparency) result when the lanolin soap, lanolin fatty acid, lanolin or suitable derivative thereof, or any mixture thereof is mixed at elevated temperature with substantially all of other soap cake components, except perfume (and possibly some other relatively minor constituents), and the resulting mixture is partially dried at elevated temperature, worked, extruded, cut into blanks and pressed to shape. The translucent soap cakes resulting, which may preferably be superfatted and contain a suitable antibacterial component, lather well, are of stable translucency on storage and are desirably mild to the skin.

  • Patent number: 4582615
    Abstract: Agglomerated particles of finely divided fabric softening bentonite and sodium sulfate particles have been found to possess improved fabric softening properties, compared to agglomerated bentonite, especially when employed in the hand washing of laundry which is subsequently line dried. Such agglomerates are also of excellent particle strength and are readily dispersible in water. The described product may be made by agglomerating finely divided bentonite and sodium sulfate powders with the aid of excess moisture, after which the agglomerated particles resulting are dried and those of desired size, preferably in the No's. 30 to 100 sieve size range (U.S.), are obtained. The fabric softening agglomerate made may be mixed with spray dried synthetic organic anionic detergent composition beads of about the same or higher bulk density, preferably in the 0.3 to 0.5 g./cc.

  • Patent number: 4573989
    Abstract: A disposable diaper comprising an absorbent pad or dual absorbent pads positioned between a top sheet and a waterproof backing sheet without the presence of wadding sheets to increase the suppleness of the diaper. A binder is sprayed between said pad or the lower of the dual pads and the backing sheet, the binder penetrating the material of the pad to stick the pad to the backing sheet to render the pad highly tear resistant.

  • Patent number: 4571303
    Abstract: Polyethylene terephthalate-polyoxyethylene terephthalate soil release promoting polymers, which have been found to be subject to losses of soil release promoting properties on storage in contact with alkaline materials, such as builder salts for synthetic organic detergents, are stabilized by melting them together with a water soluble polyacrylate and subsequently converting the melt to solid particles which contain the PET-POET polymer and polyacrylate in intimate contact. The stabilized PET-POET polymer may then be added to a synthetic organic detergent composition, very preferably one based on nonionic detergent, the builder(s) for which may be polyphosphate, non-phosphate or a mixture.

  • Patent number: 4571299
    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: 4569773
    Abstract: A particulate fabric softening detergent composition comprises certain proportions of synthetic organic detergent, builder salt, bentonite (preferably a swelling Wyoming bentonite) and water insoluble soap (preferably aluminum stearate). The detergent composition preferably comprises spray dried built detergent beads with which are blended agglomerated beads of the bentonite and water insoluble soap. The combination of water insoluble soap and bentonite greatly increases the softening action of the composition when it is employed for hand washing of laundry.
