Benefits of technology

[0009]A further advantage of the present invention is that in the compositions herein, the particles can be formulated at very low levels, whilst still providing the above benefits. Indeed, in general for other technologies, high levels of abrasive particles are needed to reach good cleaning / cleansing performance, thus leading to high formulation and process cost, incompatibility with many package e.g.: squeeze or spray bottle, low incident usage ergonomy, difficult rinse and end cleaning profiles, as well as limitation for aesthetics and a pleasant hand feel of the cleaning / cleansing composition.

[0010]The present invention is directed to a liquid cleaning and / or cleansing composition comprising abrasive cleaning particles, wherein said abrasive cleaning particles have a mean circularity from 0.1 to 0.4 and wherein said abrasive cleaning particles have a HV Vickers hardness from 3 to 50 kg / mm2.

[0011]The present invention further encompasses a process of cleaning and / or cleansing a surface with a liquid, cleaning and / or cleansing composition comprising abrasive cleaning particles, wherein said surface is contacted with said composition, preferably wherein said composition is applied onto said surface.BRIEF DESCRIPTION OF THE FIGURES

[0013]FIG. 2 is an illustration how to calculate roughness from the particle.

Problems solved by technology

The surface safety profile of such currently known scouring compositions is inadequate alternatively, poor cleaning performances is shown for compositions with an adequate surface safety profile.

Indeed, due to the presence of very hard abrasive particles, these compositions can damage, i.e., scratch, the surfaces onto which they have been applied while with less hard material the level of cleaning performance is insufficient.

In addition, such currently known scouring compositions at least in certain fields of application (e.g., hard surface cleaning) are perceived by consumers as outdated.

Indeed, in general for other technologies, high levels of abrasive particles are needed to reach good cleaning / cleansing performance, thus leading to high formulation and process cost, incompatibility with many package e.g.: squeeze or spray bottle, low incident usage ergonomy, difficult rinse and end cleaning profiles, as well as limitation for aesthetics and a pleasant hand feel of the cleaning / cleansing composition.
