Abstract: Aqueous hard surface cleaner compositions derived from metathesized natural oil feedstocks are disclosed. In one aspect, the compositions comprise at least one anionic surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, 5 octadecene-1,18-dioic acid, or their ester derivatives. In another aspect, aqueous hard surface cleaners comprising at least one nonionic or amphoteric surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. The aqueous cleaners noted above rival or outperform commercial baselines in a Gardner straight-line washability test. Industrial degreasers comprising a C10 or C12 amide solvent and derived from a metathesis-derived C10-C17 monounsaturated acid are superior to commercial standards.

Abstract: A cleaning agent for a silicon wafer (a first cleaning agent) contains at least a water-based cleaning liquid and a water-repellent cleaning liquid for providing at least a recessed portion of an uneven pattern with water repellency during a cleaning process. The water-based cleaning liquid is a liquid in which a water-repellent compound having a reactive moiety chemically bondable to Si element in the silicon wafer and a hydrophobic group, and an organic solvent including at least an alcoholic solvent are mixed and contained. With this cleaning agent, the cleaning process which tends to induce a pattern collapse can be improved.
Abstract: A wash pod is provided that includes unit dose of anhydrous wash concentrate surfactant containing at least one cationic surfactant and at least one nonionic surfactant in water soluble hygroscopic polymeric package containing the concentrate. The film encapsulates the wash formula unit dose and dissolves when placed in a bucket of water while also being chemically and physically strong enough to hold a more preferred alkaline formula as well as to remain stable during storage is provided. A low volatile organic compound (VOC) car wash formula that is highly concentrated with a low water content and contains nonionic and cationic surfactants to promote cleaning, foaming and beading, while also containing a small amount of carnauba wax is also provided. The formulation of the car wash detergent provides a streak free low residue finish on a cleaned surface.

Abstract: The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency.
