Antimicrobial hard surface cleaner

The invention provides an aqueous, antimicrobial, no-rinse hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:

A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed including a protease enzyme, a source of hydrogen peroxide and an ester substrate having the general structure ##STR1## where R and R' are alkyl groups unsubstituted or substituted with at least one functional group. Preferred substrates are defined which are preferably chemically non-perhydrolyzable. Processes for bleaching and peracid production are also disclosed.

Proteolytic perhydrolysis system and method of use for bleaching

A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed including an esterase or lipase enzyme, a source of hydrogen peroxide, and a functionalized ester substrate having the structure ##STR1## wherein R is a substituent having at least one carbon atom and X is a functional moiety or group. Preferred substrates include glycerides, ethylene glycol derivatives and propylene glycol derivatives. The system is adapted for use in both high and low temperature wash conditions. In one embodiment, a lipase enzyme is employed with an insoluble substrate and an emulsifying agent. In another embodiment, an esterase and/or lipase enzyme, a glyceride substrate and hydrogen peroxide produce a peracid with active oxygen from a peracid of at least about 0.5 ppm. Bleaching processes and stain removal capabilities are also disclosed.

Enzymatic perhydrolysis system and method of use for bleaching

The invention provides a liquid composition for deodorizing animal wastes by contact therewith. The composition comprises an aqueous dispersion which contains an ammonia-controlling-effective amount of pine oil and a dispersion aid. The dispersion aid is selected from anionic, nonionic, cationic, amphoteric surfactants, and mixtures of these surfactants.

Odor controlling animal litter with pine oil

The invention provides, in one embodiment, an odor controlling animal litter comprising:

Combined odor controlling animal litter

The invention provides a liquid composition for deodorizing animal wastes by direct application thereto. The composition comprises an aqueous dispersion which contains an ammonia-controlling-effective amount of pine oil and boric acid.

An enzymatic perhydrolysis system, useful for bleaching, has a novel enzyme, a substrate, and a source of hydrogen peroxide, and provides in situ formation of peracid in aqueous solution. The substrate is selected for enzyme catalyzed reaction, and preferably is an acylglycerol with two or three fatty acid chains. The enzyme is hydrolytically and perhydrolytically active even in the presence of anionic surfactants, has lipase activity, and is isolatable from Pseudomonas putida ATCC 53552.

Enzymatic peracid bleaching system

The invention provides, in one embodiment, an odor controlling animal litter comprising: (a) adsorbent or absorbent particles; and (b) an ammonia-controlling-effective amount of (i) pine oil and (ii) boric acid applied onto the particles. The litter can also include further adjuncts, such as fragrances, other antimicrobial additives, and the like.

A stable, cooperative enzyme system which is stable under use conditions is disclosed which comprises at least two enzymes having activity towards a relatively complex substrate with at least partial activity over the same pH range, wherein their combined activities are greater than the sum of their individual activities as determined by the formula: ##EQU1## wherein E.sub.1 and E.sub.2 are said enzymes. No additional chemical stabilizers, modifiers or activators are added to the enzymes of this invention. Particularly preferred enzymes in this invention are proteases having optimal activity in acidic, neutral or alkaline media, and mixtures of the same. A method of making this cooperative enzyme system is also disclosed. The enzyme systems of this invention have a wide variety of uses in cleaning and other applications.
