Abstract
Detergent builder/activators which can be produced from renewable resources are provided. The detergent builder/activators are obtainable by a process comprising subjecting a poly(saccharide) comprising a vicinal diol moiety to the independent steps of a) oxidative cleavage of a vicinal diol moiety with an oxidizing agent for vicinal diols to introduce carboxylic acid functionality, and b) acylation with an acylating agent.
