A gel obtainable by contacting the anhydrous suspension with water is also disclosed. Applications of the suspension and gel are also disclosed.||12-18-2014|
|20110180746||METHOD FOR PREPARING FREEZING POINT DEPRESSANT COMPOSITION - A method for preparing a composition with low corrosive effect and low freezing point, by mixing an ammonium cation source with a carboxyl anion source in an appropriate molar or weight ratio, either without a medium or by using an appropriate medium for obtaining liquid or water-soluble organic ammonium carboxylate of formula (1):||07-28-2011|
|20110088590||METHOD FOR TREATING WOOD - Described is a method for treating wood, in which the wood is brought into contact with a mixture of liquid or water-soluble organic ammonium carboxylate and an active ingredient which repels invertebrates, characterized in that the organic ammonium carboxylate has the formula (1):||04-21-2011|
|20100129304||METHOD FOR PREPARING A COMPOSITION COMPRISING A COMPOUND MIXTURE AND A CARRIER AGENT - In a method for preparing a composition including a compound mixture and a carrier agent, the compound mixture is obtained by pulverizing the wood material and/or by extracting the wood material so that the compound mixture contains at least two different compounds, selected from a first specified group, at least one compound selected from a second specified group, the compound mixture is mixed with the carrier agent, the amount of the compound mixture is kept in a range of 0.1-5 wt % from the total weight of the composition, providing that the range is also such that the total cytotoxicity of compound mixture dissolved in ethanol, measured for a HaCat cell culture after 24 h incubation period, is lower than the cytotoxicity of 0.02-0.1 wt % butylated hydroxy toluene (BHT) dissolved in ethanol for a HaCat cell culture after 24 h incubation period.||05-27-2010|
|20100129302||ANTIMICROBIAL COMPOSITION WITH LOW CYTOTOXICITY - 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 %.||05-27-2010|
|20100047294||SEMI-FINISHED PRODUCT IN THE MANUFACTURE OF A COMPOSITION FOR SKIN OR HAIR CARE - A semi-finished product is manufactured from raw liquid, extract or powder obtained from wood material, an end product composition for skin or hair care being obtained from the semi-finished product by adding one or more components thereto. The semi-finished product optionally contains a UV protector, and is a liquid, emulsion, microemulsion or nanoemulsion or a dispersion, suspension, wax, lotion or gel or a solid substance. The semi-finished product further contains an active ingredient mixture which contains phenolic compounds having antioxidative and/or microbicidal properties and/or abilities to capture free radicals. The active ingredient mixture contains as phenolic compounds at least one oligolignan, and at least two lignans, tannins or flavonoids selected from a group consisting of hydroxymatairesinol, matairesinol, oxomatairesinol, lariciresinol, cyclolariciresinol, secoisolariciresinol nortrachelogenin, pinoresinol, pinosylvine, conidendrine, melacasidine, teracasidine, ellaga-tannin or a reaction product, stereoisomer or derivative of these compounds.||02-25-2010|
|20090208767||Method For Treating Wood - 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): [NR||08-20-2009|
