摘要:
An aqueous laundry prewash stain remover composition, has on a weight basis 0.1 to 20% of at least one chelating agent from the group of citric acid, tartaric acid, and ethylene diamine tetracetic acid; 0.1 to 40% of a mixture of nonionic surfactants from the group of ethoxylated alcohols and propoxylated alcohols; 0.1 to 10% of propoxylated ethylenediamine known as N,N,N',N'-tetrakis (2-hydroxypropyl) ethylenediamine; 0.1 to 5% of alpha-olefin epoxide modified polyether thickener; 0.1 to 19.9% of an additional chelant from the group of isoserine diacetate and Beta-alanine diacetate; with the remainder of the composition being water. The composition provides enhanced stain removal on both oil and water-borne stains on a variety of fabrics. These formulations are solvent free, freeze/thaw stable, and do not precipitate on standing at room temperature.
