BACKGROUND OF THE INVENTION

The present invention relates to compositions such as cleaning compositions comprising a mix of enzymes. The invention further relates, use of compositions comprising such enzymes in cleaning processes and/or for deep cleaning of organic soiling, methods for removal or reduction of components of organic matter.

DESCRIPTION OF THE RELATED ART

Enzymes have been used in detergents for decades. Usually a cocktail of various enzymes is added to detergent compositions. The enzyme cocktail often comprises various enzymes, wherein each enzyme targets it specific substrate e.g. amylases are active towards starch stains, proteases on protein stains and so forth. Textiles surface and hard surfaces, such as dishes or the inner space of a laundry machine enduring a number of wash cycles, become soiled with many different types of soiling which may compose of proteins, grease, starch etc. One type of soiling may be organic matter, such as biofilm, EPS, etc. Organic matter composes different molecules such as polysaccharides, extracellular DNA (eDNA), and proteins. Some organic matter composes an extracellular polymeric matrix, which may be sticky or gluing, which when present on textile, attracts soils and may course redeposition or backstaining of soil resulting in a greying of the textile. Additionally, organic matters such as biofilms often cause malodor issue as various malodor molecules can be adhered by the polysaccharides, extracellular DNA (eDNA), and proteins in the complex extracellular matrix and be slowly released out to cause consumer noticeable malodor issue. There is still a need for cleaning compositions, which effectively prevent, reduce or remove components of organic soiling, an effect described in the present application as “deep cleaning”. The present invention provides new compositions fulfilling such need.

SUMMARY OF THE INVENTION

The present invention relates to a cleaning composition comprising a DNase, a Glyco_hydro_114 glycosyl hydrolase and a cleaning component. The invention further relates to compositions in particular to cleaning compositions comprising at least 0.001 ppm DNase and at least 0.001 ppm glycosyl hydrolase and a cleaning component, wherein the cleaning component is selected froma. 0.1 to 15 wt % of at least one a surfactant;b. 0.5 to 20 wt % of at least one builder; andc. 0.01 to 10 wt % of at least one bleach component

The invention further relates to the use of a composition comprising a DNase, a Glyco_hydro_114 glycosyl hydrolase and a cleaning component for deep cleaning of an item, wherein the item is a textile or a surface. The invention further relates to a method of formulating a cleaning composition comprising adding a DNase, a glycosyl hydrolase, preferably a Glyco_hydro_114 glycosyl hydrolase, and at least one cleaning component. The invention further relates to a kit intended for deep cleaning, wherein the kit comprises a solution of an enzyme mixture comprising a DNase, glycosyl hydrolase, preferably a Glyco_hydro_114 glycosyl hydrolase and optionally a protease. The invention further relates to a method of deep cleaning on an item, comprising the steps of:a) contacting the item with a cleaning composition comprising a DNase, a Glyco_hydro_114 glycosyl hydrolase and a cleaning component; andb) optionally rinsing the item, wherein the item is preferably a textile.

The invention further relates to a method of deep cleaning of an item, comprising the steps of: a) contacting the item with a solution comprising an enzyme mixture comprising a DNase and a glycosyl hydrolase and optionally a protease; and a cleaning component, wherein the cleaning component is selected from 0.1 to 15 wt % of at least one a surfactant; 0.5 to 20 wt % of at least one builder; and 0.01 to 10 wt % of at least one bleach component; and b) optionally rinsing the item, wherein the item is preferably a textile. The invention also relates to a kit intended for deep cleaning, wherein the kit comprises a solution of an enzyme mixture comprising a DNase and a Glyco_hydro_114 glycosyl hydrolase.
