Abstract: PROBLEM TO BE SOLVED: To scrape a cake of contents caused in a discharging passage and prevent in advance the discharging passage from being blocked, by providing the discharging passage of a discharging container, such as an aerosol container, with a scraping member that rotates sliding against its wall. SOLUTION: In an aerosol container, contents are discharged by depressing a button part 1, thereby opening an aerosol valve. A boss part 5 is formed on the center part of the bush-mounting hole 4 of the button part 1, and a bush 6 is fitted into the bush-mounting hole 4. On the round inside of the bush 6, large diameter parts 7 and 9 and a small diameter part 8 are formed to compose a discharging opening A. In the case, in the discharging opening A, a scraping member 12, which rotates sliding against the round inside faces of the small diameter part 8 and large diameter part 9, is provided. The scraping member 12 is held by nipping the small diameter part 8 by its own springing force. Therefore, by holding the outer end 12A of the scraping member 12 with fingers and rotating the scraping member 12 round a virtual axis B, stuff caking after sticking to the discharging opening A can easily be scraped.

Abstract: PURPOSE:To produce the subject high-quality sulfobetaine having an ester bond and useful as a bleaching-activator in an oxygen-based bleaching agent in a high yield. CONSTITUTION:A omega-halogenated fatty acid ester of phenolsulfonic acid represented by formula II is synthesized by sulfonating a omega-halogenated fatty acid phenyl ester represented by formula I (X is a halogen; R is a 1 to 3C alkylene which may be a branched chain). The resultant compound of formula II is reacted with an amine of formula III [R is a 1 to 20C alkyl, alkenyl or a (1 to 20C alkyl-substituted)aryl; R and R are each a 1 to 3C alkyl; Y is a 1 to 10C alkylene, B-(BO)n (B is 2 to 3C alkylene; n is 0 to 10); X is O, NH-CO, CO-NH, CO, O-CO, CO-O] and a polar solvent is added to the resultant reaction product. Or, the above-mentioned reaction is carried out in a polar solvent. The resultant sulfobetaine of formula IV is subsequently crystallized and separated so as to obtain the objective compound of formula IV in the form of fine crystals. As the polar solvent, one having 8 to 22, especially 10 to 12 (cal/cc) polarization parameter (PS value) is preferable.

Abstract: PURPOSE:To produce the subject compound at a low cost by directly reacting a sugar with a higher alcohol, etc., and treating the reaction product with a spontaneous liquid film evaporator, etc., while recycling the recovered unreacted higher alcohol to the alkylglycoside production process. CONSTITUTION:An alkylglycoside containing unreacted higher alcohol is produced by reacting a sugar with a higher alcohol or reacting a sugar with a lower alcohol and reacting the product with a higher alcohol. The reaction product is separated into recovered higher alcohol and a crude alkylglycoside containing 30-60wt.% of unreacted higher alcohol using a spontaneous liquid film evaporator. The alcohol is removed from the crude alkylglycoside with a forced thin film evaporator to obtain the objective compound containing
