Problems solved by technology

Therefore, in the eyes of consumers, plastic dishes are still unclean
[0004] Furthermore, grease and oil present in hard-to-reach areas of dishes such as corners or narrow crevices often cannot be removed using currently available dishwashing compositions, as is often the case with plastic containers, for example

Embodiment 1

[0126] Example 1 : Prepare the following compositions A to G (the weight percent of the value given in the total composition), and test according to the above test method:

[0127] combination

[0128] 1 SB99 from Rhodia, 2 Available from Alco Chemical, 3 Obtained from BASF, 4 Acquired from Reilly

[0129] For each composition, the table below shows the average difference in gloss rating for each slide, and the number of clean slides out of the 8 slides tested:

[0130] slide number

[0131] From this data it is shown that compositions A and B (without the polymer of the invention) do not provide cleaning benefits on plastic dishware, whereas compositions C to G provide significantly better cleaning performance.

Embodiment 2

[0132] Example 2 : The following compositions are examples of microemulsions according to the invention. These compositions provide good grease and oil removal from plastic dishes.

Abstract

The present invention relates to the use of a copolymer comprising at least one first monomer and at least one second monomer, said first monomer being selected from the group of acrylate, substituted acrylate, maleate, or substituted maleate, and said second monomer being selected from styrene or substituted styrene, wherein the weight ratio of said first monomer to said second monomer is from 80:20 to 20:80; polyvinyl pyrrolidone; polyvinyl pyridine N-oxide; lignin-sulphonate; polyethylene-imine alkoxylates; and mixtures thereof; in dishwashing cleaning compositions for the removal of grease and oil from plastic dishware. The present invention also relates to a dishwashing cleaning composition, comprising from 0.0001% to 5% by weight of the composition of a copolymer comprising at least one first monomer and at least one second monomer, said first monomer being selected from the group of acrylate, substituted acrylate, maleate, or substituted maleate, and said second monomer being selected from styrene or substituted styrene, wherein the weight ratio of said first monomer to said second monomer is from 80:20 to 20:80, and from 10% to 60% by weight of the composition of a surfactant system, the surfactant system comprising at least 0.5% by weight of the composition of an amine oxide. The present invention also relates to a kit comprising a container and the dishwashing composition, and to a process of cleaning dishware using the dishwashing cleaning composition.

Description

field of invention [0001] The present invention relates to hand dishwashing compositions. In particular, the invention relates to more effectively removing grease and oil from plastic dishes. Background of the invention [0002] The removal of grease and oil from dishes has long been a research goal in the field of dishwashing. While many current dishwashing products have improved the removal of the aforementioned oils from various surfaces such as metal, glass or porcelain, there is still a need for improved grease and oil removal from plastic dishes. [0003] It has now been found that when current dishwashing compositions are used to clean plastic dishes, a film of grease or oil remains on the plastic surface. As such, plastic dishes can still feel greasy and / or have a dull appearance after cleaning. Therefore, in the eyes of consumers, plastic dishes are still not clean. [0004] Furthermore, grease and oil present in hard to reach areas of dishes such as corners or ...
