  • Patent number: 6270780
    Abstract: Resveratrol, a component of a variety of common edible plants, including peanuts and red grapes, is a phytoestrogen. Resveratrol inhibits proliferation of skin epidermal cells (keratinocytes) and stimulates their differentiation. Resveratrol was also found to inhibit melanin production by skin cells and to alleviate skin irritation that may be caused by alpha-hydroxy acids. Resveratrol is useful in improving the appearance of wrinkled, lined, dry, flaky, aged or photodamaged skin and improving skin thickness, elasticity, flexibility, radiance, glow and plumpness.

  • Patent number: 6262010
    Abstract: A particulate free-flowing laundry detergent composition comprises at least two different granular components: a granular component containing anionic surfactant, and a granular nonionic surfactant component comprising from 20 to 30 wt % of nonionic surfactant on a non-spray-dried particulate carrier material comprising sodium sesquicarbonate. The nonionic surfactant component is preferably prepared by in-situ neutralisation of sodium carbonate with a water-soluble organic acid in the presence of the nonionic surfactant, in a high- or moderate-shear mixer.

  • Patent number: 6225462
    Abstract: A polysaccharide conjugate comprises a polysaccharide with an attached entity having a molecular weight of at least 5000, the polysaccharide conjugate being capable of binding to cellulose. Preferred polysaccharides include tamarind seed xyloglucan, locust bean gum and enzyme modified guar. The attached entity is suitably a protein such as an enzyme, antibody or antibody fragment, or a particle possibly having a benefit agent such as a fragrance associated therewith. Because the polysaccharide conjugate binds to cellulose, which is present in cotton and other fabrics, paper, etc., binding of the conjugate to cellulose brings the attached entity into close proximity to a surface of or containing cellulose. The invention thus enables targeting of attached entities to such surfaces. The invention also provides a product incorporating the polysaccharide conjugate of the invention. The product is conveniently a laundry product such as a fabric washing product, e.g.
