    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: A peracid precursor characterised in that it corresponds to the following general formula: wherein R represents C1-C20 alkyl, alkoxylated alkyl, cycloalkyl, aryl, alkylaryl or substituted aryl; R' and R'' independently represent hydrogen, C1-C20 alkyl, aryl, C1-C20 alkylaryl, substituted aryl or NR @@ wherein R represents C1-C30 alkyl; and L represents a leaving group, is disclosed. A peracid characterised in that it corresponds to the following general formula: wherein R, R, and R'' are as defined above; or an alkali metal or alkaline earth metal salt thereof, is also disclosed. A bleaching composition which may comprise such a peracid precursor and a bleach-effective amount of a source of hydrogen peroxide is further disclosed. New, proficient and cost-effective compounds for fabric bleaching are provided.

    Abstract: The activation of glycerol ester hydrolases, toward triglyceride oils, is correlated to the molar ratio of total triglyceride to surfactant concentrations in the test solution. This ratio dependency, when considered in laundry compositions, allows for predictable and improved utilization of these enzymes in the hydrolysis of triglyceride stains. A particularly preferred enzyme for this use is isolatable from Pseudomonas putida ATCC 53552. This enzyme, or hydrolase, has sufficient hydrolysis activity in a laundering solution to hydrolyze at least about 5 wt. % of total triglyceride stains in a laundering solution within about 15 minutes at about 25.degree.C.
