Highly concentrated acidic mixed products

摘要

It is desired, in order to save storage and transport capacity, to have available mixed surfactant mixtures whose content of active substance is as high as possible. Anionic surfactants of not more than 70%, and free-flowing mixtures of only 40% of active substance are known. The highly concentrated acidic mixed products are intended not to display these disadvantages and moreover be stable on storage for a long period and form no dioxane. For this purpose, mixed products consisting of paraffinsulphonic acid of the general formula R-SO3-H and alkyl polyglycol ether carboxylic acid of the general formula R'-O(AO)x-B-COOH are now proposed. The dry content of the mixtures is at least 70%, and the mixing ratio can be from 1:10 to 10:1. The mixtures are stable on storage and do not form dioxane. The highly concentrated acidic mixed products are used in surfactant solutions.
