  • Patent number: 6540881
    Abstract: This invention relates to a method for preventing (meth)acrylic acid from polymerizing during the course of distillation. The method provides for refining (meth)acrylic acid by a procedure including the steps of feeding a mixed gas obtained by catalytic gas phase oxidation of propylene and/or acrolein with a molecular oxygen-containing gas or a mixed gas obtained by catalytic gas phase oxidation of at least one compound of isobutylene, t-butyl alcohol, or methacrolein with a molecular oxygen-containing gas, to a (meth)acrylic acid collection column, collecting a (meth)acrylic acid-containing solution from the mixed gas, and feeding the (meth)acrylic acid-containing solution to a distillation column while maintaining the total concentration of aldehydes of 2-4 carbon atoms and acetone in the solution at a level of not more than 2000 ppm based on the amount of (meth)acrylic acid.

  • Patent number: 6531444
    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: 6521794
    Abstract: For the production of an aromatic compound by hydrolyzing and decarboxylating a corresponding aromatic cyano compound in the presence of an acidic substance, this invention provides a method for the production of the aromaic compound, characterized by carrying out the reactions of hydrolysis and decarboxylaion in multiple steps. Particularly when the aromatic cyano compound contains a halogen, this method effectively prevents the reaction vessels from being corroded by the by-produced hydrogen halogenide and enables the target compound to be produced in a high yield.

  • Patent number: 6517822
    Abstract: A formulation is described for straightening hair comprising alkanoic acids and a diluent, wherein the diluent is advantageously present at greater than 5% by volume, and more preferably greater than 20% by volume. The inventive formulation is acidic and does not use an effective amount of an alkaline hair-straightening agent to perform the hair straightening function. Instead, the step of hair straightening is accomplished by applying the non-alkaline formulation to the hair and then either leaving the formulation in the hair without rinsing or rinsing the formulation out of the hair followed by optional shampooing and/or conditioning. Consequently, a safe and surprisingly effective solution is provided for hair-straightening including hair-straightening maintenance, relaxation of curl, and reduction of frizziness (e.g., in humid weather).

  • Patent number: 6518484
    Abstract: The present invention provides a nucleic acid molecule isolated from the 5′ untranscribed region of a translationally controlled tumor protein (TCTP) gene from Arabidopsis. The nucleic acid molecule, referred to as TCTP promoter in the present invention, directs the high-level expression of a reporter gene that is properly placed under its control. The TCTP promoter initiates and regulates the gene expression to a level that is comparable to those by the currently available promoters in plant genetic engineering. A minimum of 300-bp region is enough for fill regulatory activity. The TCTP promoter is functional in all plant tissues tested with the highest activity in the meristem tissue of root tip. The present invention can be utilized to express useful genes to a high level in agronomically important plants.

  • Patent number: 6491902
    Abstract: The present invention is a controlled delivery system that can be incorporated in hair care products such as shampoos, conditioners, hair styling products, and other hair care products to effectively deliver a broad range of active agents and sensory markers, such as fragrances or cooling agents onto the hair. The system also prolongs the release rate of the active agents or sensory markers over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance “burst” upon blow drying the hair or other types of heat treatment. The controlled delivery system of the present invention is a nano-particle, having an average particle diameter of from about 0.01 microns to about 10 microns. The nano-particle comprises hydrophobic polymers and co-polymers, cationic charge boosters in conjunction with cationic surface-active conditioning agents that assist in adhering the particles onto hair.

  • Patent number: 6491955
    Abstract: A &bgr;-D-galactosidase which is encapsulated with fatty acid ester, does not exert its hydrolysis function in milk but hydrolyze lactose in the human body. Hence, the milk containing the encapsulated &bgr;-D-galactosidase, does not change in sweetness with storage and is digestible to the &bgr;-D-galactosidase-deficient people. In addition, the milk can maintain its characteristic taste without off-flavor by virtue of the excellent feature of fatty acid ester.
