Embodiment

[0077] Preparation of Example Compositions

[0078] Typical compositions illustrating certain preferred embodiments of the compositions of the present invention can be formulated according to the following schemes and are detailed in Table 1.

[0079] In a suitable sized container add weighed water and then add the ingredients in the following order: thickener, surfactant, solvent, acid and lastly the color and fragrance components. All ingredients were added at room temperature and the components were mixed using a mechanical stirrer with a small diameter paddle at the end of the stirrer shaft. Mixing is continued for 5-120 minutes until the specified composition is homogeneous. This exemplary composition is easy to pour and maintains good mixing properties (ie, forms a stable mixture) over extended periods of time (even greater than 120 days). It should be noted that the ingredients can be added in any order, but it is preferred to add the water first to the mixing vessel ...

Abstract

Alkaline aqueous hard surface cleaning compositions which exhibit good cleaning efficacy against hardened dried or baked on greasy soil deposits. They are storage stable, and are not undesirably irritating to the skin or mucous tissues of the user. These compositions comprise in percent by weight (based on 100% total weight of a composition): 0.01-0.85% wt. nonionic surfactant compound based on an amine oxide; 0-1.5% wt. chelating agent; 0.01-2.5% wt. caustic; 3.0-9.0% wt. glycol ether solvent system comprising one glycol ether or glycol ether acetate solvent having a solubility in water of not more than 20% wt., and a second glycol ether or glycol ether acetate having a solubility of approximately 100% wt., wherein the ratio of the former to the latter is from 0.5:1 to 1.5:1; 0-5.0% wt. of a water soluble amine containing organic compound; 0-2.5% wt. soil anti-redeposition agent; 0-2.5% wt. optional constituents. The compositions according to the invention contain no anionic or cationic type surfactant constituents, and include no more than 10% wt. of volatile organic constituents (VOCs). Methods for the use of such cleaning compositions, and processes for their production are also disclosed.

Description

technical field [0001] This invention relates to hard surface cleaners which are particularly useful for cleaning greasy surfaces. In particular, the present invention relates to cleaning compositions which are particularly suitable for cleaning hard surfaces having hardened or baked on greasy soils. Background technique [0002] Various cleaning compositions are known in the art that are effective for cleaning hard surfaces such as those commonly found in kitchens and bathrooms. Many such compositions have specific cleaning benefits for specific types of stains deposited on the hard surface. Types of these stains include mineral and salt deposits also known as hard water scale. Other types of stains that are particularly difficult to remove are aged, dried or baked-on stains (which are often the residue of cooking grease). When such deposits are rare and / or the substances have not dried or hardened over time, they are generally not difficult to remove. In contrast, most...
