THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE

INVENTION:

FIELD OF THE INVENTION:

The invention particularly relates to a composition for rapid liberation of oxygen in the environment for pest repellent and the process for making the same wherein said composition when mixed with water liberates oxygen with a controlled release mechanism such that the release of oxygen suppresses the percentage volume of carbon dioxide in the surrounding area thus repelling the mosquitoes and other pest that strive for carbon dioxide to live and find their host. Said composition comprises a mixture of oxygen generating compounds, pH buffers, metal catalysts, at least one biopolymer that controls, the release of components and liberation of oxygen. The invention also describes various application of said composition wherein said composition can also be used as a bioremediation in waste waters, a swimming pool water cleanser, as a plant nutrient, and an aquaculture booster etc.

BACKGROUND OF THE INVENTION.

Repelling mosquitoes is a hard task, there are some traditional methods that are followed wherein if the situation has not grown into an overpopulating state then it is easy to compress them into less numbers. Other methods that are used on large scale are classified into physical pest control, biological pest control, chemical pest control, and mechanical pest control. Physical method for prevention of pest growth and management include household cleaning of garbage that may hold water, making banks of holding ponds steeper to discourage emergent vegetation, cleaning rain gutters, periodically changing stored water. People also put mosquito-eating fish into man-made lakes and let the fish eat them until the numbers decreases. People repel mosquitoes using things that counteract with the female mosquitoes environmental cues, such as C02, heat, and water vapor. The most used chemical to repel mosquitoes is Deet (N,N-diethyl-3- methylbenzamide). Another chemical that is used is Ultrathon. This is more likely to be used in the military. Another repellent is citronella. This is a repellent but does not work as well as deet. A formula based on geranoil is also used in this case. US5079868 discloses use of urea peroxide to reduce the population or inhibit the growth of bacteria and protects the aerial parts of the plant such as leaves, fruits, flowers and soft stems. Normal pesticide formulations contain various solvents made mostly from Methanol etc, and there is a wide concern that usage of such solvents in specialty pesticide formulations is to be totally discouraged. The use of such solvents, even at a lower rate, demands large amounts of surfactants and other additives which make the cost of such formulations very high compared to the actives.

Many household insecticide products, such as mosquito coils, have been used for personal protection. Most of them are based on the insecticidal activity (knock-down and mortality) of the active ingredient. Most of these are not safe to Elderly, pregnant, neonatal, patients etc.

US 20130084347 Al describes an alcohol-free insect repellent composition includes: (a) from about 30 to about 60 weight % of lemongrass oil; (b) from about 15 to about 40 weight % of essential oil of lemon eucalyptus; (c) from about 10 to about 30 weight % of rose geranium oil, and (d) from about 2 to about 20 weight % of litsea cubeba oil; the balance of the insect repellent composition to 100 weight % being water; wherein the insect repellent composition is free of non-naturally occurring ingredients. Mosquito repellent compositions comprising an active agent and an oil-soluble, water insoluble acrylate polymer having specific solubility parameters of approximately 6- 10 (cal/cc)^l/2 in poorly hydrogen bonding solvents are disclosed in US

4816256A.

These pest control harms vegetation best disclosed in US5079868 wherein use of urea peroxide to reduce the population or inhibit the growth of bacteria and protects the aerial parts of the plant such as leaves, fruits, flowers and soft stems. Bug spray consists of deet making it repellent to mosquitoes and other bugs. Deet though, is the best repellent, and finding bug sprays with deet in them are sure to work for hours. Biological method of pest control includes use of proteins from Bacillus thuringiensis US 20140072546 disclose use of bacillus thuringiensis as a neonicotinoid insecticide for the control of dipteran larvae and enhancement of efficacy of insecticidal seed treatment.

Problem using chemical methods and others have drawbacks like creating health hazards owing to the presence of the pesticide residues in food, fiber and fodder, environmental pollution, Ecological imbalance by loss of non targeted pests, Development of resistance by the insects. JP62- 103002 discloses use of calcium and magnesium peroxide for improvement of initial growth of the plants, germination and seedling emergence. Thus what is needed is a solution to either overcome this hazardous effect of pesticides or chemical used to repel mosquitoes and/or develop a composition which is not harmful for humans in this process. US7160483 discloses use of calcium and magnesium peroxide as a solid chemical source of active oxygen.

US20090075818 discloses use of nano silver colloid for killing of microorganism on seeds and treatment of various diseases in agriculture field and thereby increasing shelf life and quality of agriculture products.

There is still a larger need for a specific and safe formulation for controlling household pests like mosquitoes, termites, bed bugs and other biting/blood sucking pests in a simple, safe, eco friendly and cost effective form without affecting human health. Moreover to maintain ecological balance, use of insecticides and pesticides can be easily replaced by safe and eco- friendly pest repellants. Accordingly, there is a need to develop environmentally safe house hold pest repellant formulations which contain Carbon dioxide diluents (By increasing the volume of Oxygen percentage) and which are further storage stable, efficacious, and economical.

DETAILED DESCRIPTION OF THE INVENTION:

The present invention has been described by way of examples only and it is recognized that modifications are falling within the scope and spirit of the appended claims, and which would be obvious for a person skilled in the art based upon the disclosure herein, are also considered to be included within the scope of this invention.

The invention describes a composition for increasing oxygen levels in a confined area wherein said composition which comprises several oxygen liberating compounds, pH buffers and metal catalyst and at least one biopolymer.

Said composition wherein oxygen liberating compounds are selected from peroxides, perborates, percarbonates, and per sulfates etc. pH buffers are selected from the group of organic acids like lactic acids, tartaric acid, citric acid, formic acid and butyric acid etc. but not limited to those mentioned here.

Also noble metal is chosen from gold and silver, whereas biopolymer is selected from one or more of the collagen, chitosan, hyaluronic acid but not limited to those mentioned here. These noble metals are nano sized and are bioencapsulated.

The main functionality of the invention disclosed is to repel mosquitoes by providing oxygen release into the atmosphere. Normally, the female mosquito attack is recorded frequently and prefers type O blood living beings, or those who breathe heavily, or those whose skin surface includes more colonies of bacteria, pregnant females, and those living forms with lot of body heat.

Researchers have observed that semiochemical; Culex quinquefasciatus that is released by human dermis attracts mosquitoes to humans. Another compound identified in human blood that attracts mosquitoes is Sulcatone or 6-methyl-5-hepten-2-one.

The mosquitoes have specific ways of finding their prey, like chemical, visual, and heat sensors. Normally these insects possess mechanisms to sense carbon dioxide and invade the area where CO2 is high and find the hosts.

In Aedes, a yellow fever mosquito, the search for a host takes place in two phases; first, the mosquito exhibits a nonspecific searching behavior until the perception of host stimulants, then it follows a targeted approach. Thus the invention stated in the specification focuses on diluting the carbon dioxide concentrations by liberating more oxygen into the atmosphere wherein the mosquitoes will fail to find its prey and thus prevent them to bite and suck the blood from the vessels. Said composition also serves as a plant nutrient into the soil with low porosity and less permeable air.

There are few factors that cause mosquitoes to sense the presence of human prey includes Fast metabolism of the cholesterol by which by-products are expelled through skin surface, pregnant people since they exhale large amount of carbon dioxide that attracts mosquitoes and can be detected up to 164 feet away, people and particularly pregnant women with higher body temperature, Increased amount of certain bacteria on the skin, especially Staphylococcus epidermidis, those who release more steroid by-products, uric acid, lactic acid and ammonia through skin via sweating and/or other natural compounds through breading, type O blood people, as type A blood are the least attractive to mosquitoes, type B are moderately attacked by mosquitoes.

Above all mentioned these insects possess mechanism to sense carbon dioxide and invade the area where there is carbon dioxide and find their host.

In addition to the above mentioned features of the invention, said invention also have additional implementations in various fields such as listed below:

Promote soil fertility by making oxygen bio available to the soil micro flora and the plants, improve survival of the plants and micro flora and the plants, improve survival of the plants and soil micro flora in water clogged conditions and thus aid to increase plant growth and crop yield. Also protects plants from the attack of pest by serving as a soil friendly bacterium pesticide.
