Abstract: Methods for treating surfaces with lipase to provide an enzyme-surface complex and surfaces so treated facilitate oil removal. One such treated surface is a fabric with lipase sorbed onto the surface. A preferred sorbed lipase is isolatable from a Pseudomonas organism or clone. Treated fabrics have substantial hydrolysis activity for oil stains and perhydrolytic activity for oil stains, have altered surface wettability, and retard oil and hydrolysis by-produce redisposition in the presence of aqueous solutions. The sorbed lipase is resistant to removal during fabric laundering and retains substantial hydrolytic activity even with exposure to drying at elevated temperature. The hydrolytic activity of the lipase-fabric complex persists during storage or wear. Hydrolysis by-products are removable during laundering at basic pH or in the presence of surfactant.

Abstract: Conc. non-phosphate detergent compsn. rapidly soluble in cold water, comprises (by wt.): (a) 10-50% nonionic surfactant(s); (b) 5-70% water-insoluble non-phosphate builder(s); (c) 0-70% water-soluble non-phosphate builder(s); where the ratio (b+c): a is at least 1.0, and the ratio b:a is below 2.0. The surfactant is pref. an opt. branded, prim. or sec. ave. 6-16C alcohol ethoxylated with 2-10 moles ethylene oxide or ethoxylated-propoxylated with 1-10 moles ethylene oxide and 1-10 moles propylene oxide; opt. branched alkylphenoxy polyethoxy alcohol of ave. chain length 8-16C and ave. 1.5-30 moles ethylene oxide, and corresp. ethoxylated-propoxylated derivs. contg. 1-10 moles each of ethylene oxide and propylene oxide; or mixts. of these.

Abstract: A PVA film modified with anionic comonomers is provided for use as a water-soluble seal or pouch for alkaline or borate-containing cleaning compositions. The films comprise copolymers of 90-100% hydrolyzed vinyl alcohol with a nonhydrolyzable anionic comonomer, and have molecular weights characterized by a viscosity range of 4-35 cPs. The films are resistant to insolubilization caused by alkaline or borate-containing additives, are storage stable over a wide range of temperature and humidity storage conditions, rapidly and fully solubilize in a wash solution, and do not significantly impair cleaning performance of an additive enclosed within.

Abstract: In one embodiment, the invention provides novel low-temperature-effective non-phosphate detergent paste compositions which comprise a concentrated non-phosphate, detergent paste composition which is rapidly soluble in cold water. The composition by weight comprises, about 10-50% of at least one nonionic surfactant, about 5-70% of at least one water insoluble non-phosphate builder, about 0-70% of at least one water soluble non-phosphate builder, wherein the ratio of (b+c): a is greater than or equal to about 1.0; and the ratio of b:a is less than about 2.0.
