Abstract: A wiping sheet includes a patterned part of a fiber assembling base material and a non-patterned part of the fiber assembling base material. The patterned part includes cellulose nanofiber; and the non-patterned part does not include the cellulose nanofiber.

Abstract: A wet-sheet laminated body includes multiple folded wet sheets that are stacked such that an end portion of one wet sheet among the wet sheets is sandwiched by a folded-back portion of another wet sheet among the wet sheets. Each of the wet sheets includes a base material sheet impregnated with a chemical solution such that impregnated portions that are impregnated with the chemical solution and non-impregnated portions that are not impregnated with the chemical solution are provided. The impregnated portions and the nonimpregnated portions are formed in a stripe pattern in which the impregnated portions and the non-impregnated portions are alternately arranged.

Abstract: A wiping sheet having a plurality of nonwoven fabrics that are stacked and bonded together includes cellulose nanofiber that is included in an applied part where adjacent nonwoven fabrics among the nonwoven fabrics are bonded. At least one of the adjacent nonwoven fabrics is a spunlace nonwoven fabric.

Abstract: A process for producing a glycolipid having a high eicosapentaenoic acid (EPA) content is provided, which process comprises fractionating the whole lipids of marine chlorella by means of a combination of solvent-fractionation with column chromatography, which glycolipid has platelet agglutination-inhibiting effect, serum cholesterol-increase-inhibiting effect, etc. of EPA and also having a higher absorption rate in intestinal canal than EPA triglyceride or ethyl ester.

Abstract: A fatty acid composition is produced by subjecting a lipid composition extracted from marine chlorella to solvent fractionation to remove neutral fats, chlorophyll, sterols and majority of phospholipids, thereby providing a polar lipid composition. The polar lipid composition is then subjected to hydrolysis to liberate fatty acids. Finally, the fatty acids are recovered, thereby providing a fatty acid composition with not less than 60% by weight of eicosapentaenoic acid.
