Cationic group-containing cellulose ether

Provided is a cationic group-containing cellulose which, when incorporated in a hair wash composition, is able to give an excellent smootheness feeling and its sustained feeling in rinsing and give a good coat feeling, and which, when incorporated in a skin cleanser composition, is able to give an excellent moist feeling to the skin after washing and drying, and also provided are a surfactant composition, a hair wash composition, a skin cleanser composition, a hair conditioner composition and a hair treatment composition containing the cellulose ether. [1] A cationic group-containing cellulose ether, which has a main chain derived from an anhydroglucose, and in which the degree of substitution with a cationized oxyalkylene group per the anhydroglucose unit is from 0.01 to 1.0, the degree of substitution with a glycerol group is from 0.5 to 5.0, and the degree of substitution with a group that contains a branched hydrocarbon group having from 8 to 18 carbon atoms and has a specific structure is from 0.001 to 0.2; [2] a surfactant composition containing the cationic group-containing cellulose ether, a surfactant and water; [3] a hair wash composition, a skin cleanser composition, a hair conditioner composition and a hair treatment composition containing the cationic group-containing cellulose ether, a surfactant and water.

Strategies for reducing leaching of water-soluble metal biocides from treated wood products

Strategies that dramatically reduce leaching of water-soluble metal-containing biocides from treated biodegradable products. Aqueous, preservative compositions of the present invention incorporate one or more water-soluble metal species having biocidal activity and one or more agents that increase the leaching resistance of these metal species when impregnated into biodegradable products. Using one or more of these agents allows usage rates of the biocide impregnants to be dramatically lowered at the time of impregnation of the products. Because less of the metal biocide leaches in the presence of these agent(s), less biocide has to be added in order to meet desired loading goals. Generally, an agent of the present invention that reduces leaching of metal biocides is water soluble, is substantially nonionic in aqueous media, has a molecular weight greater than about 100, and has a vapor pressure less than that of water at standard temperature. Preferred agents are those including at least 10 weight percent, more preferably at least 16 weight percent, and even more preferably at least 20 weight percent oxygen. Examples of these preferred agents include (poly)ethers and/or nonionic surfactants including one or more oxyalkylene units in the backbone and/or as substituents of the molecule.
