A BUILDER FOR AN ALKALINE DETERGENT

摘要

The invention relates to a builder for an alkaline, water-based detergent, the purpose of which is to bind into a complex form the polyvalent metal ions present in the washing water and to act as a deflocculant and dispersant of the aggregates formed by the dirt particles detached during the wash and the tenside of the detergent. Approximately 20-100 % of the dry matter content of the builder according to the invention consists of hydroxycarboxylic acids formed as byproducts in alkaline pulping, possibly together with a lignin having a low molecular weight and/or lignosulfonate, and approximately 0-80 % consists of a builder or builders known per se.
