Novel methods and compositions for treating textiles and other materials are disclosed in which persistent odor or other symptoms of biofilm presence can be reduced through the use of compositions comprising N-acetyl cysteine or other agents in combination with certain enzymes.

The invention provides a method of inhibiting lipase activity in a detergent composition, said method involving incorporation of from 0.25 to 40 wt. % of a saponin into said lipase containing composition, wherein said detergent composition preferably is a home care detergent composition, more preferably a laundry detergent composition; and to the use of saponin to inhibit lipase activity in a detergent composition, preferably a laundry detergent composition, wherein the saponin is present in the detergent formulation at a level of from 0.25 to 40 wt. %, wherein said detergent composition preferably is a home care detergent composition, more preferably a laundry detergent composition.

Cleaning compositions comprising variants of an alpha-amylase, methods of making such cleaning compositions and methods of treating surfaces such as fabrics with aqueous liquor comprising such compositions.

A substrate or coating is provided that includes a protease with enzymatic activity toward a component of a biological stain. Also provided is a process for facilitating the removal of a biological stain is provided wherein an inventive substrate or coating including a protease is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from the substrate or said coating.

The disclosure relates to hard surface cleaning compositions, methods of making the hard surface cleaning compositions, and methods of using the hard surface cleaning compositions. The hard surface cleaning compositions are enzymatic and near neutral in pH. In particular, the hard surface cleaning compositions have reduced surface tension for cleaning surfaces with low surface free energy. Preferably, the hard surface cleaning compositions have low contact angles on a variety of surfaces. In a preferred embodiment, the hard surface cleaning compositions comprise a biocide.

Described herein is a detergent composition including (A) at least one polymer including (a) a core that includes one to 3 moieties of general formula (I),

##STR00001## where Z are different or the same and are selected from the group consisting of C.sub.2-C.sub.12-alkylene and C.sub.3-C.sub.12-cycloalkylene A.sup.1 are different or the same and are: selected from the group consisting of C.sub.1-C.sub.12-alkylene, C.sub.6-arylene, and C.sub.3-C.sub.12-cycloalkylene, or based on citric acid, X.sup.1 is selected from the group consisting of hydrogen, methyl, ethyl, and combinations of at least two of the foregoing, n is in a range of 1 to 100; and (b) polyalkylene oxide chains.

Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C.sub.14-C.sub.30 alkyl chain and a polar group bonded to a central zone carbon of the C.sub.14-C.sub.30 alkyl chain. The alkylene-bridged surfactants comprise a C.sub.12-C.sub.18 alkyl chain, a polar group, and a C.sub.1-C.sub.2 alkylene group bonded to the polar group and a central zone carbon of the C.sub.12-C.sub.18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

The present disclosure is in the field of enzyme technology, in particular the lipolytic action of enzymes on fats and oils, as used, for example, in washing agents or cleaning agents. The present disclosure relates to an agent, in particular washing or cleaning agent, which contains a lipase as defined herein. Furthermore, the present disclosure relates to a method for the cleaning of textiles and the use of the agent as contemplated herein for the removal of soilings.

The present invention relates to compositions, methods and use of a mixture of enzymes having DNase activity and an enzyme having hexosaminidase activity.

Amides of an aliphatic polyamine with two or three molecules of 12-hydroxyoctadecanoic acid, wherein the polyamine comprises at least one primary amino group for each molecule of 12-hydroxyoctadecanoic acid and additionally at least one secondary and/or tertiary amino group, can be used in a lipase stable thickener composition comprising from 50 to 95% by weight of one or more of the amides, from 5 to 50% by weight of one or more diluents and from 0 to 10% by weight water, and such thickener compositions can be prepared by a step of heating a starting mixture comprising hydrogenated castor oil and one or more aliphatic polyamines and adding one or more diluents before or after the heating step.
