Description
BIODEGRADABLE ECOLOGICAL CLEANER
FIELD OF THE INVENTION
The present invention generally relates to solvents or cleaning compositions.
More particularly, the invention relates to a novel cleaning formulation comprising esters, more specifically methyl or ethyl esters, more specifically long chain fatty acid methyl and/or ethyl esters.
BACKGROUND OF THE INVENTION
For decades industrial and household cleaning products have been utilized to provide certain tasks such as paint removers, cleaners, etc. Solvents are also used to clean, maintain, and prepare wood, metal, masonry, natural and synthetic fabrics, and plastic components. Although providing the needs of these many mission-critical tasks, most solvents generally, are toxic, thus posing a threat to health and to the environment.
These environmental and health threats include ozone depleting air pollutants and water pollution that threaten aquatic organisms and drinking water supplies.
Many of these solvents are carcinogenic and hazardous to health in general.
Although the government, industry and the community at large are all relatively well informed to the dangers of toxic solvents, the need to use such solvents has not dramatically diminished their use. Safer handling, disposal, recycling, recovery and other responsible methods of dealing with toxic substances is improving.
However, the availability of safer alternative solvents is still not widespread, which is due, primarily, to the high cost of the solvent alternatives and because the majority of the environmentally safer solvent alternatives do not provide a satisfactory performance.
In order for an "environmentally friendly" cleaner alternative to gain widespread acceptance, the cleaner should meet several criteria. First, it should perform effectively.
Second, it should be economically viable and affordable. Third, it should be widely available and, of course, it should be non-toxic to the environment generally and to humans specifically.
Several alternative cleaners or solvents have been introduced by industry for decades, but in general they do not meet the criteria stated above. Furthermore, many of these solvents are not completely biodegradable, just less toxic. Various compositions of esters in conjunction with other solvents have been used as cleaners or solvents as well as paint removers known as paint strippers.
US patent 6,613,158 discloses composition of a chewing gum remover. Its composition consists of a C1-C 4 alkyl ester of a C6-C 22 saturated or unsaturated carboxylic acid, a terpene and an oil-soluble surfactant.
US patent 6,191,087 discloses composition of an environmentally friendly solvent. It consists of mixture of C1-C 4 ester of C16-C 20 fatty acid and ester C1-C 4 of lactic acid.
US patent 6,096,699 teaches environmentally friendly paint stripper or fat and grease remover, which consists of mixture of C1-C 4 ester of C16 -C20 fatty acid, C1-C 4 ester of lactic acid, a surfactant and a thickener in different weight proportions.
US patent 5,340,495 teaches compositions for cleaning ink from a printing press consisting of a methyl ester of a C8 -C22 fatty acid and a non-ionic surfactant which is an ethoxylated C4-C 10 alcohol.
None of the discussed patents teaches use of fatty acid esters without addition of other chemical compounds as a cleaner.
SUMMARY OF THE INVENTION
The present invention contemplates an environmentally friendly cleaner. It is biodegradable in normal sewerage treatment plants, and has no volatile content so that it can be used indoors with minimal ventilation.
A contemplated cleaner composition comprises C1 - C2 ester of C14- C24 of fatty acid, which leaves a grease residue on a treated surface after use.
The invention is also defined as use of composition comprising C1 -C2 ester of C14-C 24 of fatty acid as cleaner, which leaves a grease residue on a treated surface after use.
A cleaner comprising methyl and/or ethyl ester or mixture in any proportion of two or more methyl and\or ethyl esters yield in a transesterification process of long chain fatty acids C14-C24.
The invention is also defined as use of methyl and/or ethyl ester or mixture in any proportion of two or more methyl and\or ethyl esters yield in a transesterification process of long chain fatty acids C14-C24 as a cleaner.
The cleaner as defined above wherein said fatty acid ester is an ester of an oil selected from the group consisting coconut oil, palm oil, olive oil, canola oil, peanut oil, hemp oil, safflower oil, sunflower oil, corn oil, cotton seed oil, flax seed oil, rapeseed oil, soy bean oil, jojoba oil, recycled fryer oil, fish oil and tallow.
Use of the cleaner as defined above wherein said cleaner is used to remove rubber or rubber composition stains from any surface.
