Description

DESCRIPTION PASTE COMPOSITION FOR CLEANING HARD SURFACES Field of Invention The invention refers to deposits of liquid or oil stains that have encrusted on a hard surface. pertains to a composition for removal.

Known Issues of the Invention Hard surface cleaning compounds include kitchen tiles, sinks, stovetops, chimneys, platforms and soiled items such as kitchen utensils, cutlery and crockery It is intended for cleaning surfaces such as Such surfaces are often liquid or solid. to heavy contamination as they come into contact with fatty substances, eg cooking environments. they tend. Over a period of time, these deposits tend to harden or crust. shows. Remove oil stains and grease when they do not harden or crust. It is usually easy to remove, but once the shell has been removed, for example, by standing or cooking. When they are attached, it is very difficult to remove the stains. As long as it doesn't crust, the stain it is easier to clean. If not removed immediately, encrusted liquid or fat It adheres firmly to the hard surface. By removing solid oil stains in document US 5849105 A liquid crystal detergent composition is disclosed for cleaning hard surfaces. The subject compound is a nonionic surfactant, an alkyl benzene sulfonic acid magnesium salt, an amorphous siliceous abrasive, a co-surfactant, a water-insoluble It contains organic compounds and water. Hard-surface cleaning compositions are generally high It has pH. However, low lead formats are also known. with high pH The compositions are more effective in removing stains, largely thanks to their superior alkaline structure. is good. However, such compositions are rigid. On the other hand, neutral to slightly acidic pH Although the compounds with it are not as harsh, they are not as effective as the others.

Thus, such compositions often contain hard abrasive particles, typically 3.5 in. More include those with the Mohs index on it. anionic surface formed by reacting dolomite with its stoichiometric excess Compositions in the form of detergent bars with active ingredient are disclosed. Reaction, a calcium that leaves a significant portion of the free dolomite to undergo a corrosive heat LAS and magnesium lead to a mixture of LAS.
