Abstract
Sequestrant compositions comprising combinations of an alkali metal or ammonium borate with an adduct formed by reaction of an .alpha., .beta. unsaturated polycarboxylic acid with a mono- or dicarboxylated sugar, in which the adduct has at least two hydroxy groups in a vicinal configuration. The sequestrants can be used to complex alkaline earth and transition metal ions and are especially useful for complexing calcium and magnesium in aqueous laundry solutions. They also are effective for soil dispersion and for inhibiting the deposition of soil on fabric.
