Abstract: Brighteners for detergents consisting of a mixture of 4,4'-bis-(2-morpholino-4-anilino-1,3,5-triazinylamino)-stilbene-2,2'-d isulfonic acid-di-Na salt and from 5 to 50% by weight, calculated on said brightener, of another brightener of the formula +TR in the above formula, M is an alkali metal cation, preferably sodium, X is a group of the formula -COR2 or -SO2R3, R2 being C1-C8-alkyl and R3 being C1-C5-alkyl, C4-C8-cycloalkyl, phenyl or toluyl, Y is hydrogen or C1-C5-alkyl, A is C3-C6-alkylene, R1 is hydrogen, C1-C5-alkyl, C4-C8-cycloalkyl, or a group of the formula and Z is an anilino group, a chloroanilino group or a morpholino group. Said brightener mixtures are color-stable and do not show any green discoloration even after a prolonged storage in a moist atmosphere.

Abstract: Liq. rinsing and cleansing compsns. contain (a) sec. 8-24(12-18) esp. 14-16C alkane sulphonates and/or alkylaryl sulphonates with 9-18C in alkyl gp. and (b) 8-20(12-16)C alpha-olefin sulphonates, provided component wt. ratio (a):(b) is 90:10-50:50. Compsns. are used esp. for washing dishes by hand. Other uses are washing lacquered and polished hard surfaces and tiles. Compsns. have improved cleaning power and solubility. Tenside components are easily available, do not irritate skin and cause no waste water pollution problems.
