Abstract
Disclosed is a highly effective detergency builder system comprising the combination of particular ether carboxylate sequestering agents and particular types of dispersing/anti-redeposition agents. Such selected ether carboxylates can include oxydisuccinate, tartrate monosuccinate and/or tartrate disuccinate. Such particular dispersing/anti-redeposition agents can include salts of acrylic acid-based polymers and co-polymers or can include certian ethoxylated amine materials. This selected combination of particular ether carboxylate sequestering agents and particular dispersing/anti-redeposition agents provide an especially useful builder system for use in phosphorus-free detergent or laundry additive products.
