Abstract:
This invention provides a crease removing composition which can remove creases in textile products without sacrificing any handle without conducting heat treatment such as ironing and steam pressing. The crease removing composition comprises a specific alkylene oxide adduct (a) represented by general formula (1) or (2) or (3). There is also provided a method for removing creases of textile products which comprises applying this crease removing composition to a textile product.
Abstract:
A liquefying alkaline α-amylase having the following enzymological properties: (1) action: this enzyme hydrolyzes α-1,4-glycoside linkages of starch, amylose, amylopectin and partial hydrolyzates thereof, and forms glucose, maltose, maltotriose, maltotetraose, maltopentaose and maltohexaose from amylose, though it does not act upon pullulan; (2) isoelectric point: it has an isolectric point exceeding 8.5 as measured by isoelectric electrophoresis. This enzyme has such a liquefying activity as to hydrolyze starch and starch polysaccharides at high random and has an optimum pH value on an alkaline side. Since it has a high isoelectric point, it can readily be purified. A detergent composition containing this enzyme has an excellent detergency against especially stains due to spilt food.
Abstract:
The invention provides a soil-releasing agent and detergent compositions containing the same. The invention relates to a crosslinked compound obtained by reacting a compound having 2 to 32 hydroxyl groups (such as triethanolamine) with a compound having at least two hydroxyl-reactive functional groups (such as (poly)ethylene glycol diglycidyl ether); a soil-releasing agent consisting of the crosslinked compound; and detergent compositions containing the soil-releasing agent.
Abstract:
A method for screening a half-dry smell deodorizer, said method comprising contacting a microorganism capable of producing 4-methyl-3-hexenoic acid with test substances in the presence of sebum stain components, detecting the formation of a substance causing the half-dry smell by the microorganism, and thus selecting a test substance having an effect of deodorizing the half-dry smell. A method for evaluating a half-dry smell deodorizer, said method comprising contacting a microorganism capable of producing 4-methyl-3-hexenoic acid with a test substance in the presence of sebum stain components, detecting the formation of a substance causing the half-dry smell by the microorganism, and thus evaluating the half-dry smell deodorization effect of the test substance.

Abstract:
The invention provides a soil release agent and a detergent composition blended therewith. The invention relates to a crosslinked product obtained by reacting a compound having 2 to 32 hydroxyl groups, such as triethanol amine, with a compound having at least two functional groups reacting with hydroxyl groups, such as (poly)ethylene glycol diglycidyl ether, a soil release agent containing the crosslinked product, and a detergent composition containing the soil release agent.
