  • Publication number: 20100129302
    Abstract: A composition includes at least one antimicrobial agent; a possible solvent system with either hydrophobic or hydrophilic nature, selected according to the target of usage; as well as possible surface active agent. The compound mixture is obtained by pulverizing wood or plant material and/or by extracting the possibly pulverized wood or plant material, so that the compound mixture contains at least two different polyphenolic compounds selected from the following group: lignans, stilbenes, juvabiones and flavonoids; the compound mixture further containing oligomers of the polyphenolic compounds, so that the compound mixture preferably has the following properties: the compound mixture has an antimicrobial effect in the composition; the cytotoxicity of the polyphenols contained in the compound mixture is at least 10 times lower with respect to BHT; the compound mixture does not irritate the skin in a so-called single patch test with contents of 0.1 wt %.

  • Publication number: 20090208767
    Abstract: Described is a method and a composition for preparing wood, to its use and to the wooden product obtained by the method. The method and the composition use liquid or water-soluble organic ammonium carboxylate of formula (1): [NR1R2R3R4]+ n [R5(COO)n]?n (1), in which R1, R2 and R3 are selected from hydrogen, substituted alkyls containing 1-6 carbon atoms and unsubstituted alkyls containing 1-6 carbon atoms, R4 is a substituted alkyl or an unsubstituted alkyl containing 1-6 carbon atoms, R5 is hydrogen, a substituted hydrocarbyl containing 1-6 carbon atoms or an unsubstituted hydrocarbyl containing 1-6 carbon atoms, and n is an integer 1-6. This substance has good absorption into and high retention in wood.
