Abstract:
Film-forming compositions are disclosed that can comprise, on a dry solids basis, 25 to 75 % by weight of certain starch derivatives and 25 to 75 % primary external plasticizer. The starch derivatives can be chemically modified starches that range in molecular weight from 100,000 to 2,000,000. The high levels of plasticizer in the films give excellent film flexibility and integrity.
Abstract:
Waste water discharged from septic tanks and toilets into sewage contains salts contained in feces, chlorine compounds contained in toilet cleansers, and other salts and chlorine compounds contained in daily waste water. Since these salts and chlorine compounds inhibit the proliferation of microorganisms in the waste water, microbial degradation of organic and inorganic contaminants cannot well proceed in septic tanks and sewage disposal plants. Further, there arises an environmental problem due to the offensive smell. To solve these problems, toilet paper containing pineapple enzyme and at least one powder selected from among slag, porous ores and active carbon is provided. Each time the toilet paper is used, the substances capable of degrading chlorine compounds and eliminating offensive smell (i.e., pineapple enzyme and slug, porous ores or active carbon) are discharged into a stool together with feces and fed into the waste water or sewage in a septic tank. Thus, salts and chlorine compounds in the toilet sewage are reduced and the offensive smell is eliminated, thereby reliving the load in the processing of the waste water in the septic tank or a sewage disposal plant.
Abstract:
A thermoplastic film is comprised of an admixture of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and a functional amount of a cellulose ester plasticizer. The film has an opacity in the range of 10 to 85 percent, a thickness in the range of 0.05 to 0.25 mm (0.002 to 0.010 inch), a porosity in the range of 0.0 to 50 ml/min/cm at a 1.0 centibar pressure drop and a compostability of less than 65 days fragmentation. The film is prepared by making a paper comprised of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and saturating the paper with a functional amount of a cellulose ester plasticizer. The saturated paper is subjected to heat and pressure for a period of time to obtain the thermoplastic film. The thermoplastic film is prepared without the use of solvents and is economically attractive since it is compatible with conventional paper printing materials and techniques.

Abstract:
A method of producing a filler, for high-performance liquid chromatography for preparing optical isomers separately, inexpensively and easily. The method contributes to improvement of the quality of the product prepared separately, maintains the separation power of the chromatography and minimizes the quantity of eluate. A material filler prepared by coating a supporter with a polysaccharide derivative is rinsed with a solvent to produce the title filler which produces little eluate derived from the polysaccharide derivative.
Abstract:
The disclosure provides a tissue product comprising at least one multi-layered tissue web that includes a first fibrous layer and a second fibrous layer. The first fibrous layer comprises wood fibers and the second fibrous layer comprises cotton fibers. Cotton fibers are present within the second fibrous layer in an amount from about 1 to about 2 percent by weight of the layer, in some embodiments from about 5 to about 20 percent by weight of the layer, and in some embodiments, from about 10 to about 15 percent by weight of the layer. The selective incorporation of cotton fibers in the tissue web results in a web having improved handfeel without negatively effecting strength and durability.
Abstract:
The invention provides systems and methods for removing a target oil from an aqueous fluid stream using a capture medium. In embodiments, the capture medium can comprise an anchor substrate and a modifier technology supported on the anchor substrate, where the modifier technology complexes with the oil to form a removable complex.
