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 roughness from 0.10 to 0.3 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compositions at least in certain fields of application (e.g., hard surface cleaning) are perceived by consumers as outdated.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.

examples

[0157]These following compositions were made comprising the listed ingredients in the listed proportions (weight %). Examples 1-43 herein are met to exemplify the present invention but are not necessarily used to limit or otherwise define the scope of the present invention.

[0158]Abrasive particle used in the examples below were ground from rigid polyurethane foam (controlled foam structure e.g.: foam density, cell size, strut aspect ratio and % cell size content). Polyurethane foam is synthesized from reaction of a diisocyanate (e.g.: base on polymeric methylene diphenyl diisocyanate) and polyols (e.g.: polyether or polyester-based polyol). Wherein the diisocyanate is for example Lupranate M200R from BASF and the polyol is for example Lupranol 3423 from BASF. Foam were ground into small particles and sieved using a rotary mill and particle selection was done with used of air jet sieving instrument from Retsch.

are made the following way:

[0160]Add Carbopol® to de-ionized free water of the formulation. Add all surfactants except cationics and betaines. If the pH is less than 6 then add a neutralizing agent (typically a base i.e., Triethanolamine, sodium hydroxide) to adjust to a pH greater than 6. If necessary, apply gentle heat to reduce viscosity and help minimize air entrapment. Add betaine and / or cationic surfactants. Add conditioning agents, additional rheology modifiers, pearlizing agents, encapsulated materials, exfoliants, preservatives, dyes, fragrances, abrasive particles and other desirable ingredients. Lastly, if desired reduce the pH with an acid (i.e. citric acid) and increase viscosity by adding sodium chloride.
