  • Patent number: 6905520
    Abstract: According to the invention, a metal salt and an oxygen source are applied to penetrate or impregnate a suitable substrate sequentially in effective amounts so as to react in contact with the substrate and produce a mineral compound fixed within the surface of the substrate. The inventive combination of a mutually compatible metal salt, oxygen source, and substrate brings about an in situ reaction, and modifies the substrate to bring about a lasting desired effect. The mineral compound that is produced according to the invention is linked to the substrate, is stable and long-lasting or permanent, and is immobilized or insolubilized in the substrate. The mineral compound is bound or contained within and on the surface of the substrate, so it may be said to be ingrained in the fibers or matrix of the substrate, or embedded within the substrate. The desired effect is preferably a color. A wide variety of metal salts may be used depending on the desired effect.

  • Patent number: 6482240
    Abstract: Collagen membranes are formed from porcine rinds (i.e., pig skins) for us in a variety of applications and, most preferably, for wrapping food products, such as hams and the like. First, after removing skins from the porcine, the skins are promptly frozen. In later processing, the rinds are thawed and then enzymatically defatted. Then, a quick alkalinic hydrolyzation is performed on the rinds. Then, an acidic hydrolyzation is performed on the rinds. The rinds are then ground into a gel-like fluid mass. Finally, the fluid mass is extruded, sheeted and dried into a collagen membrane. The collagen membrane produced can be, in preferred embodiments, used for wrapping food products, such as hams.

  • Publication number: 20020157189
    Abstract: A method for the treatment of a non-finished textile component in a cold batch process is provided. The method comprises the steps of treating a non-finished textile component in an aqueous bleaching solution of hydrogen and a hydrophobic bleach activator or hydrophobic peracid followed by a treatment time of from about 1 hour to about 15 hours at a temperature of 35° C. or less. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method provides acceptable whiteness and superior fiber protection and fabric strength benefits in significantly reduced treatment times versus conventional.

  • Patent number: 6440177
    Abstract: In the present invention there is provided a single-step process and composition of hair bleach, which can simultaneously lighten the hair up to seven levels and effectively neutralize any undesirable warmth, provide natural tones or deposit fashion shades. This is achieved by including in the bleach mixture a solution containing basic dye molecules, which in the present invention have been found to be both, stable in the bleach, and capable of depositing the desired amount of tone on the hair. The dyes fall into the class of water-soluble basic azo compounds.

  • Publication number: 20020046427
    Abstract: An amino acid-N,N-diacetic acid (AADA) or its salt with an equivalent or less of an alkali metal is produced by reducing, through electrodialysis, alkali metal ions from an aqueous solution of the alkali metal salt of an AADA. By this configuration, an AADA salt can be produced in a much higher yield than conventional equivalents without requiring a regeneration operation of a resin as in the use of an ion exchange resin or without requiring crystallization-separation of crystals of the AADA salt as in the addition of an organic solvent.
