摘要:
A transparent detergent bar possessing good foaming power and detergency in hard water is formulated consisting essentially of at least one salt of a N-long chain acyl-optically active acidic amino acid neutralized with a basic amino acid in the ratio of 1 mol of the former to 1 to 2 mols of the latter and water in the range of 5 to 35% based on the weight of the bar apart from water. Other adjuvents may be present.
摘要:
Monosaccharides are oxidized by an oxygen-containing gas in the presence of a special palladium-carbon catalyst which is prepared by adsorbing palladium on active carbon at a temperature lower than 60.degree. C while the active carbon is suspended in an aqueous solution of an alkali metal hydroxide or carbonate and then reducing the palladium with formaldehyde.

A refined product of a polyoxypropylene fatty acid isopropanolamide surfactant, having a high stability in storage and a very small change in smell thereof, is obtained by heat-treating an addition-reaction mixture prepared from a compound of the formula (III) and propylene oxide in a molar amount of 0.5 to 10 times that of the compound of the formula (III), and containing the target compound of the formula (I) and an oxazoline compound of the formula (II) produced as a by-product with water or an alkaline aqueous solution at 50 to 100° C., to hydrolyze the oxyazoline compound and to control the content of the oxyazoline compound to 0.1% by mass or less; and a detergent composition containing the refined product in a content of 1 to 50% by mass, exhibits enhanced thickening, foaming, emulsifying, dispersing and dissolving properties. [R1═C1–C19alkyl or alkenyl group, X=oxypropylene group, n=average number of addition-reacted X groups of 0.5 to 10]
