Sodium salts of citric, glycolic, diglycolic and three sugar acids, directly derived from D‐glucose, were evaluated as builders in a formulation for a linear alkylbenzene sulfonate detergent. Only sodium citrate and diglycolate were at least 60% as effective as sodium tripolyphosphate in building action in hard water. Detergency appeared to be related to calcium sequestration by the salts at pH 10.
