Liquid concentrated aqueous solutions of salts of alkyl ether carboxylic acid, and a process for preparing such solutions |
摘要 |
This invention relates to liquid concentrated aqueous solutions of salts of alkyl ether carboxylic acid derived from alkanols having at least 10 C atoms, which aqueous solution of the salts of alkyl ether carboxylic acid also contains ethoxylated or ethoxylated and carboxymethylated products or mixtures thereof, derived from polyhydric alcohols, the degree of ethoxylation of those products being at least 0.5. The invention also relates to processes for preparing such liquid aqueous solutions. |
