Abstract:
PROBLEM TO BE SOLVED: To provide a slipping property-improving agent for washing which makes hand-washing easy by the improvement of slipping properties between objects to be washed in hand-washing and achieves hand care effects and clothes care effects of avoiding shape deformation, a slipping property-improving agent for hand-washing, detergent composition comprising these slipping property-improving agents, and a hand-washing method improved in slipping properties at the time of scrubbing objects to be washed each other in hand-washing. SOLUTION: The slipping property-improving agent comprises potassium metaphosphate having a viscosity in an aqueous solution of 200 mPas or more which is measured under the below condition. The condition is that adding 2 g of potassium metaphosphate with 50 ml of water, agitating for one minutes, adding 4 g of sodium tripolyphosphate with 50 ml of water, agitating for three hours and measuring viscosity with a condition B type viscosimeter at 25°C. The detergent composition comprises the slipping-improving agent for washing and a solubilizing agent. The hand-washing method comprises washing under a condition of the concentration in water of potassium metaphosphate of at least 30 mg/L and a bath ratio of at least 2. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide qualitative and quantitative analyzing methods enhanced in reliability with respect to a water soluble compound having a sugar skeleton in a surfactant-containing sample wherein the presence of the water soluble compound having the sugar skeleton is estimated. SOLUTION: The qualitative analyzing method has a process (1) for mixing the surfactant-containing sample with a mixed liquid of heavy water and a strong acid or a heavy strong acid, a process (2) for hydrolyzing the water soluble compound having the sugar skeleton in the mixture obtained in the process (1) and a process (3) for measuring the mixture passing through the process by an H-NMR method. The quantitative analyzing method for the water soluble compound having the sugar skeleton in the surfactant-containing sample wherein the presence of the water soluble compound having the sugar skeleton is estimated has a process (1) for mixing the surfactant-containing sample with the mixed liquid of heavy water and the strong acid or the heavy strong acid, a process (2) for hydrolyzing the water soluble compound having the sugar skeleton in the mixture obtained in the process (1), a process (3) for adding an internal standard substance before or after the process (3) and a process (4) for measuring the mixture passing through the process (2) and containing the internal standard substance by the H-NMR method.
