Description

Cleansing composition

Technical field

The present invention relates to the washing of tableware, in particular refers to dishwashing methods suitable for removing dirt from cooked foods, Baked or burned kitchen utensils and crockery, cutlery and glassware.

Background of the invention

Dirt from cooked, baked or burned food is among the types of dirt that are harder to remove from surfaces. Traditionally, removing dirt from cooked, baked or burned food from kitchen utensils and crockery, cutlery and glassware requires soaking the dirty object before a mechanical action. Apparently, the dishwasher process alone does not provide a satisfactory removal of dirt from cooked, baked or burned foods. The manual dishwashing process requires a huge rubbing effort to remove dirt from cooked, baked or burned food and this can adversely affect the safety and condition of kitchen utensils / crockery, cutlery and
glassware.

The use of cleaning compositions that contain solvents to facilitate the removal of dirt from Cooked, baked or burned food is known in the art. For example, the patent US-A-5,102,573 provides a method to treat hard surfaces stained with residues of cooked, baked or dried food that includes applying a Pretreatment composition on the dirty article. The applied composition comprises surfactant, reinforcing additive of the detergency, amine and solvent. The patent US-A-5,929,007 provides a aqueous cleaning composition for hard surfaces to remove hardened dirt deposits of dried or baked fat. The Composition comprises non-ionic surfactant, chelating agent, caustic alkali, a glycol ether type solvent system, organic amine and anti-redeposition agents. In WO-A-94/28108 describes a aqueous concentrated cleaning composition that can be diluted to form a more viscous use solution comprising an amount thickener effective of a micelle thickener composition of bacilli, glycol alkyl ether solvent and agent hardness sequestrant. The request also describes a method to clean a food preparation unit that has the least a practically vertical surface that has a Baked food dirt coating. In practice, no However, none of the techniques have proved very effective for remove polymerized dirt from baked food from substrates Metallic and other substrates.

The use of solvents in the context of the dishwasher. In JP-A-10.017.900 describes a auxiliary dishwashing composition comprising non-surfactant Low foaming ionic, organic solvent and water. The composition offers advantages of detergency and drying. In JP-A-11,117,000 describes a auxiliary dishwashing composition comprising surfactant, high molecular weight organic polyelectrolytes, water soluble solvent and water. The claimed auxiliary composition contributes to the cleaning of persistent dirt such as due to oil or lipstick.

There is still a need for a method and products that have improved efficacy for the elimination of dirty food cooked, baked or burned utensils of kitchen and crockery, cutlery and glassware using a dishwasher and avoiding the use of a pretreatment stage.

Summary of the invention

According to a first aspect of the present invention, a method is provided for removing dirt from cooked, baked or burned foods (such as fat, meat, Dairy products, fruit, pasta and any other specialty food difficult to remove after cooking process) kitchen utensils and crockery, cutlery and glassware (including stainless steel, glass, plastic, wood and objects ceramic).
