It has been found that certain polyhydroxy alkyl amines are very readily soluble in water, alcohols and mixtures thereof. The concentrated solutions described consist essentially of water, alcohols, preferably C1 to C3 alcohols, or water/alcohol mixtures as solvents and at least one dialkyl aminopropyl glucamine of the following formula (1), Z-NH-CH2CH2CH2-NR1R2 in which R1 and R2 are the same or different and are C1 to C4 alkyl or hydroxyalkyl with 2 to 4 carbon atoms and Z is a linear polyhydroxy hydrocarbon radical with at least three possibly oxalkylised OH groups. The concentrated solutions are particularly suitable for the production of the corresponding polyhydroxy alkyl carboxylic acid amides.
