  • Stabilization of household, body-care and food products by using benzotropolone containing plant extracts and/or related benzotropolone derivatives
    Patent number: 9663442
    Abstract: Disclosed is the use of benzotropolone derivatives of formula wherein R1, R2 and R7 independently from each other are hydrogen; C1-C3alkyl; or COR8; R3 is hydrogen; or COOR9 R4 is hydrogen; or C1-C3alkyl; R5 is hydrogen; hydroxy; C1-C3-alkoxy; or —O—(CO)—R10; R6 is hydrogen; C1-C3alkyl; or COR8; or R5 and R6 together may form a five or six membered ring; or R6 and R7 together form a five or six membered ring; and R8, R9, R10 independently of each other are C1-C30alkyl; for protecting body-care and household products from photolytic and oxidative degradation.

  • Wire cloth
    Patent number: 8889571
    Abstract: A wire cloth includes warp wires and weft wires which cross each other and are interwoven by a weave pattern. The warp wires are formed in at least two different configurations to define warp wires of first and second types. A length of the first type of warp wires deviates from a length of the second type of warp wires in relation to a particular length unit, with pores being formed in interstices between sections of two neighboring warp wires and crossing sections of two neighboring weft wires.

  • MIXTURES COMPRISING BENZOTRIAZOLES AND MEROCYANINES
    Publication number: 20130251650
    Abstract: The present invention relates to the use of a stabilizing composition comprising (a) an effective stabilizing amount of at least one merocyanine derivative having an absorption maximum of 350 to 400 nm, and (b) at least one UV filter selected from benzotriazole derivatives; and optionally (c) at least one excited state quencher; for the protection of body care and household products against the deleterious effects of light, heat and oxygen.
