Description

[Detailed description of the invention] The present invention relates to a vehicle cleaning composition.

There has been a remarkable trend in recent years to shift from iron-based surface-coated vehicles to aluminum, aluminum alloy, or stainless steel vehicles due to aesthetics, vehicle lifespan, and energy savings associated with weight reduction. These aluminum, aluminum alloy, and stainless steel vehicles are said to be less susceptible to contamination than vehicles with iron-based surface coatings, and are also useful in terms of maintenance measures.

It is highly regarded as a new vehicle.

However, aluminum, aluminum alloy, and stainless steel vehicles have surfaces treated to prevent reflections (accidents), and their surfaces are uneven, and due to their structure, they are subject to many stains that are difficult to clean.

Vehicle pollution can be roughly divided into: ■ Mineral oil-based or animal/vegetable oil-based pollution ■ Metal [mainly iron] oxide-based pollution ■ Others include silicon oxide-based pollution, dust, dirt, etc. Cleaning with a chemical composition is carried out.

Conventional cleaning agents include: ■Alkaline cleaners made mainly of alkaline salts and surfactants ■Weakly alkaline cleaners made mainly of chelating agents ■Acidic cleaners made mainly of organic acids such as oxalic acid and citric acid ■Neutral detergents based on surfactants are used.

Although these existing cleaning agents may be effective against individual contaminations listed in (1) to (4) above, no cleaning agent has yet been found to be effective against multiple contaminations.

For example, the alkaline cleaning agent described in (1) above is particularly effective against mineral oil or animal and vegetable oil-based contamination (2), but it is not practical for cleaning metal oxide-based contamination (2), and the weak alkaline cleaning agent described in (3) Agents are not practical for the metal oxide contamination described in (1) above, or the other contaminations described in (2) above.

The acidic cleaning agent (@) above is not practical for cleaning mineral oil-based or animal/vegetable oil-based contamination ((2) above).

Furthermore, the neutral cleaning agent (2) above is hardly effective against metal oxide contamination (2) and other contamination (2).

Furthermore, for strong alkaline and strong acid type cleaning agents,
There is a strong demand for cleaning agents in the neutral range because it poses a risk of corrosion to aluminum or aluminum alloy vehicles and causes deterioration of some paints and glass backing resins.

Note that cleaning may be carried out using physical means such as brushing with the detergents listed in ■ to ■ above, but strong alkaline and strong acid type detergents pose problems in work safety, and neutral detergents may not be used. However, the improvement in effectiveness is insufficient. Furthermore, it is known that surface roughening, which is carried out as an anti-reflection measure, can be damaged, and cannot be said to be an effective means.

The present inventors have arrived at the present invention as a result of intensive research to solve these problems. That is, the present invention provides (1) one or more compounds selected from oxycarboxylic acids, their alkali metal salts, and amine salts, and/or (2) aminopolycarboxylic acids, these (3) nonionic, anionic, amphoteric, and cationic surfactants. one or more surfactants [0.5 to 40% by weight, one or more compounds selected from ocarboxylic acids, their alkali metal salts, ammonium salts and amine salts [
Consisting of 5-70% by weight water and one or more of fragrances, deodorants, solubilizers, thickeners, pH adjusters, antifoaming agents, and rust preventives [0-30% by weight] A vehicle cleaning composition is provided.

The cleaning composition of the present invention is suitable for vehicles that are composed of: - Mineral oil-based or animal and vegetable oil-based contamination; - Metal [mainly iron] oxide-based contamination; - Other silicon oxide-based contamination, dust, dirt, etc. It exhibits excellent cleaning effects against complex contamination, and can be cleaned by hand, spray, and in some cases soaked or brushed, and is effective against resins such as aluminum, aluminum alloy alumite, paint, and glass backing. This is an excellent detergent composition for vehicles in a neutral range that is safe and can be used in a wide range of cleaning temperatures from room temperature to high temperatures.

Next, the constituent components of the composition of the present invention will be explained.

■Ingredients include citric acid, glycolic acid, malic acid,
Examples include tartaric acid, gluconic acid, lactic acid, and their alkali metal salts and amine salts.

Examples of the component (2) include aminopolycarboxylic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, or their alkali total salts and amine salts.

■Ingredients include polyoxyalkylene (ethylene) alkyl phenyl ether type nonion, polyoxyalkylene (ethylene) alkyl ether type nonion, polyoxyethylene polyoxypropylene block polymer type nonion, polyoxyethylene glycol alkyl ester type nonion, Nonionic surfactants such as sorbitan fatty acid ester type nonion, sucrose fatty acid ester type nonion, fatty acid salt type, alkylbenzene sulfonate type, alkyl l & acid ester salt type, linear secondary sulfonate type, dialkyl sulfosuccinate ester salt anionic surfactants such as polyoxyethylene alkyl or alkylphenyl ether sulfate salt type, polyoxyethylene alkyl or alkylphenyl ether phosphate ester or salt type, alkylcarboxybetaine type, alkylaminocarboxylic acid type, alkylimidase Examples include amphoteric surfactants such as phosphorus, cationic surfactants such as alkylpicolinium chloride types, alkyltrimethylammonium chloride types, and other quaternary ammonium salt types.

Examples of the component (2) include thiocarboxylic acids such as thioglycolic acid and thiomalic acid, or alkali metal salts, ammonium salts, or amine salts thereof.

■Ingredients include fragrance ingredients, deodorizing ingredients, solubilizers such as xylene sulfonate and toluene sulfonate, thickeners such as carboxymethyl sululose and methyl cellulose, and p.
H21! ! Acid or alkali components, antifoaming agents,
There are rust preventives, etc.

The pH of the cleaning composition of the present invention is preferably 4-10, more preferably 6-9.

In addition, in the constituent components of the present invention, if component (1) and/or component (2) exceeds 80% by weight, the above-mentioned (1) metal [mainly iron] oxide contamination is inferior, and if it is less than 1% by weight, (2) mineral oil It is not preferable because it is less resistant to contamination by system or animal and vegetable oils, and (2) other contaminations such as silicon oxide contamination, dust, and sand.

■ If the component is less than 0.5% by weight, it is inferior to the above-mentioned ■ mineral oil-based or animal and vegetable oil-based pollution, and Exceeding the level is undesirable as it is inferior to metal [mainly iron] oxide contamination.

■If the component is less than 5% by weight, ■Inferior to metal [mainly iron] oxide-based pollution, and if it exceeds 70% by weight, ■Mineral oil-based or animal/vegetable oil-based pollution, and ■Other silicon oxide-based pollution. , dirt, sand, etc., and is not preferable.

The cleaning composition of the present invention can be prepared by appropriately mixing the above-mentioned components.

As mentioned above, the cleaning composition of the present invention can be used to prevent vehicle contamination from: ■ Mineral oil-based or animal and vegetable oil-based pollution, ■ Metal [mainly iron] oxide-based pollution, and ■ Other silicon oxide-based pollution. ,
It has extremely excellent cleaning performance against complex contamination such as dust and dirt, and cleans the vehicle itself [aluminum, aluminum alloy, etc.] in the neutral range.
This vehicle cleaning composition is safe for alumite and resinous backings such as paint and glass, is easy to handle in liquid form, and can be washed by hand, sprayed, brushed, or immersed.

Furthermore, the cleaning composition of the present invention may be used by diluting the cleaning composition of the present invention with water as appropriate depending on the intended use.
