Abstract: Compositions comprising (A) a total of from 2 to 30% by weight, based on the total composition (A)+(B), of one or more amino alcohols of formula (1) herein R1, R2, R3 and R4 are each independently of the others hydrogen, 1-C12alkyl,C5-C24aryl or C6-C36aralkyl, and R5 and R6 are each independently of the other hydrogen or C1-C4alkyl; and (B) from 70 to 98% by weight, based on the total composition (A)+(B), of a fluorescent whitening agent of formula (2) herein X is hydrogen, an alkali metal ion, an ammonium ion or a hydroxyalkylammonium radical derived from the amino alcohol of formula (1), and R7, R8, R9 and R10 are each independently of the others —OR11, —NR11R12 or a group of formula (3) wherein R11, and R12 are each independently of the other hydrogen, alkyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl, H2N—CO-alkyl or alkylthio, are distinguished by high solubility in water and by high storage stability of the aqueous solutions.
