  • Patent number: 10717894
    Abstract: Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.

  • Patent number: 5221496
    Abstract: 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, ethylene diamine tetracetic acid, isoserine diacetic acid and Beta-alanine diacetic acid; 0.1 to 40% of nonylphenol ethoxylate; 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; 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.
