Description

CROSS-REFERENCE TO RELATED APPLICATIONS The application corresponds to PCT/EP2021/075774, filed Sep. 20, 2021, entitled “A HARD SURFACE CLEANING COMPOSITION”, which claims priority to EP20197227.0 filed Sep. 21, 2020, the entirety of both are incorporated herein by reference. FIELD OF THE INVENTION The present invention relates to a cleaning composition, in particular, it relates to an aqueous hard surface cleaning composition providing enhanced antimicrobial benefit. BACKGROUND OF THE INVENTION Consumers involve in various cleaning activities in their day-to-day life, such as, laundering, washing utensils, cleaning house-hold items etc. The common goal of the cleaning activities is to wash off foreign elements such as, particulate, dust, dirt, oily soil, microbes etc. residing on a surface. Literature suggests that these elements, particularly microbes may cause serious health issues. Hence it is important for consumers to clean themselves and their surroundings. Consumers may use water to clean their belongings and it is observed that dust or particulates may be cleaned by washing with water. But certain foreign elements, like oily soil, microbes etc., may not be cleaned by water wash. Hence for better cleaning and enhanced removal of these foreign elements, consumers prefer to use cleaning compositions. There are different types of cleaning compositions available for cleaning different surfaces or applications, such as, laundry detergent, hard surface cleaners etc. Hard surface herein includes dishes, tableware, cooking utensils, tabletop, ceramic surface, glass surface etc. These compositions differ in terms of quantity of surfactant, types of surfactants, emulsifier, emollient, thickener, sequestrant, builder, perfume etc. For example, dishwash compositions are used for cleaning dishes and kitchen utensils which are having high amount of oily soil deposition. Hence most of the dishwash compositions are rich in surfactant content. US 2015/0252310 (Ecolab USA Inc., 2015) discloses a hard surface cleaning composition including an anionic surfactant salt, a saturated C8 to C10 alkyl amide solvent, a cosolvent and water that works at least as well as well as d-limonene. The document further discloses that the composition can remove red food soils with up to 20 percent protein and works as an asphalt removal composition. U.S. Pat. No. 5,281,354 (Amway Corporation, 1994) discloses a liquid cleanser composition for hard surface cleaning. The composition comprises a terpene selected from mono- and sesquiterpenes and mixtures thereof, a water miscible solvent, an amide surfactant and abrasive. However, consumers desire to have an improved hard surface cleaning composition which is capable of cleaning microbes along with oily soil, dust and particulates from a surface. Therefore, there is a need for an improved hard surface cleaning composition for providing antimicrobial benefit. It is an object of the present invention to provide a composition for cleaning a hard surface, in particular, the composition should be able to provide antimicrobial benefit in addition to cleaning. Surprisingly, the present inventors have found that a hard surface cleaning composition comprising a combination of alkene amide and glycol ether provides significant antimicrobial benefit. SUMMARY OF THE INVENTION Accordingly, in a first aspect, there is provided an aqueous hard surface cleaning composition comprising: a) 0.01 to 20% by weight alkene amide;b) 0.01 to 20% by weight glycol ether of formula (I): R1O(R2O)nR3; where, R1 is a linear or branched alkyl or phenyl group having 1 to 8 carbon atoms;R2 is ethyl or isopropyl;n is 1, 2, 3;R3 is hydrogen or a linear or branched alkyl or phenyl group having 1 to 10 carbon atoms; c) 0.1 to 50% by weight surfactant; andd) at least 10% by weight water. Accordingly, in another aspect, there is provided a method for cleaning a hard surface, comprising steps of: optionally wetting the surface;applying a composition according to the first aspect on the surface using an applicator; and,rinsing the surface with water. Accordingly, in another aspect, there is provided a use of a composition according to the first aspect for cleaning a hard surface. These and other aspects, features and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description. For the avoidance of doubt, any feature of one aspect of the present invention may be utilized in any other aspect of the invention.
