COMPLETE SPECIFICATION

1. Title of the invention: -
A super spreading silicon base non ionic surfactant and process for making the same.Visilon 8083 Grade.
2. Field of the invention: -
The present invention relates to spreaders more particularly to the non ionic super spreaders for plants for reducing cultivation cost of crop..
3. Back ground of Invention with regard to the drawback associated
with the known art-
Surfactants (surface active agents) are a type of adjuvant designed to improve the
dispersing/emulsifying, absorbing, spreading, sticking and/or pest-penetrating properties
of the spray mixture. Surfactants are used to increase the resistance of a component
added to the compositions of the present invention from being removed by rain, dew or
irrigation. Surfactants are particularly useful when applying a pesticide to a plant with
waxy or hairy leaves. Surfactants that are used as dispersing agents have the ability to
adsorb strongly onto a particle surface and provide a charged or steric barrier to
reaggregation of particles. Water-repellent wax (cuticle) on a plant surface is the major
barrier to the spreading, retention and penetration of pesticides. Surfactants are mostly
used to overcome this barrier by, for example, forming bridges between water and wax
on a leaf surface, or altering the permeability of the leaf cuticle.

The Super spreader is used in the product to promote distribution of the hydrocolloid suspension, and decrease the surface tension present on both the leaf surface and the insect cuticle. The super spreader action maximizes spray coverage on the leaf surface in spite of the hydrophobic nature of the leaf and insect exoskeleton. Further, when ionic ally charged, the high molecular weight polysaccharide micelles have a greater attraction to the insect exoskeleton rather than the leaf surface. This attraction causes the active ingredients to gather around and adhere to the insect body, enhancing effectiveness.
In case fertilizer mix, due to the high spreading capacity of super spreader, fertilizers get spread and penetrated in soil deeply, so reach early to roots of plant, before it get absorbed by weeds and also before it get evaporated in air.
The most commonly used surfactants are anionic, non-ionic, or mixtures of the two types. Spreaders change the surface tension of a spray droplet. Super spreaders are used for adding to herbicide spray solutions.
Non ionic surfactants are useful when it is desired to increase the transport of such an additive through plant cuticles and are recommended for use with systemic herbicides, nutrients and the like. As Non ionic surfactants have no electric charge. Non ionic surfactants are often used with systemic pesticides and help pesticide sprays penetrate plant cuticles. Non ionic surfactants are compatible with most pesticides.
Organo silicone surfactants are a group of surfactants that are used in place of traditional surfactants. They reduce surface tension, increase spreading ability and improve rainfastness (the amount of time between a pesticide application and rainfall)
One of the prior art means is disclosed in patent no 5552/DELNP/2008.The present embodiment is a disinfectant and bacterial aqueous compositions. The present invention provides a disinfectant and/or bactericidal aqueous composition containing an olanexidine acid addition salt, and at least one polyoxyethylene-based nonionic surfactant selected from the group consisting of polyoxyethylene higher alkyl ethers and polyoxyethylene alkylphenyl ethers; a disinfectant and/or bactericidal aqueous composition containing an olanexidine acid addition salt at a concentration of 0.05 to 0.5

WN%, and an alcohol at a concentration of 20 to 80 WN%, and not containing any surfactants; and a disinfectant and/or bactericidal aqueous composition containing an olanexidine acid addition salt , and at least one member selected from the group consisting of ester-based nonionic surfactants and cyclic oligosaccharides.
Another one prior art means is disclosed in patent no. 92/CHENP/2008 A. The present embodiment is a immunological adjuvant emulsion. The invention relates to a thermo reversible oil-in-water adjuvant emulsion corriprising at least: squealing; an aqueous solvent; a nonionic surfactant which takes the form of a polyoxyethylene alkyl ether; and a hydrophobic nonionic surfactant, in which 0% of the volume population of the oil drops measures less than 200 nm in size. The invention also relates to a method of preparing an immunogenic composition, in which at least one vaccine antigen is mixed with an oil-in-water emulsion. The invention is characterized in that the oil-in-water emulsion is obtained using a method involving phase inversion by means of temperature variation.
Another one prior art means is disclosed in patent no. US 2007/0037711 A1 titled as film forming spreading agents. The present composition comprises a)99.80 % by wt or less of at least one particle; b)fi!m forming spreading agent present in an amount of i)equal to or greater than 0.20% by weight if a spreader inhibitor is not present or ii)equal to or greater than about 0.35 % by weight if a spreader inhibitor is present ;and optionally c)at least one volumization agerit The present composition is used in agricultural compositions and in non agricultural uses.
So the agricultural spreaders present in the prior art means are mainly ionic in nature, many are non ionic also but having emulsifier base. They are toxic to the plants and reacts with other pesticides /fertilizers. They may stick to fruit, thus causes toxic spot in fruit. These spreaders are not cost effective to farmers as more quantity per litre of spreader is required. (0.25 ml to 5ml per litre of water).Its spreading diameter is 5 to 25 mm and it penetrates the soil upto 5 cm. So these spreaders are not recommended in drip irrigation due to its ionic nature and use of chemical emulsifiers. So there is a need

for a emulsion free non ionic, cost effective spreader for plants. The present invention is non toxic to the plant as well as ecology system.
Disadvantages of the prior art are as follows.
1) Toxic to plants and costly.
2) Harmful chemical emulsion to the product.
3) Sticks to fruits and causes spots on fruits. Advantages of the present embodiment are as follows.

1. Chemical emulsion free non ionic super spreader.
2. Very low quantity use per lit of water (Dose - just 10ml per lit of water)
3. Reduces cultivation cost of crop.
4. Reduces use of pesticides by 20-30%.
5. Can be used in drip irrigation fertilizers.
6. Can be used for dipping process of grapes and other fruits.
7. Improves spreading and penetration of spray solution by reducing spray volume.

8. Detailed description of the Invention with the reference to drawing:-
The foregoing objects of the invention are accomplished and the problems and shortcomings associated with prior art techniques and approaches are overcome by the present invention described in the present embodiment.
Detailed descriptions of the preferred embodiment are provided herein; however, it is to be understood that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or matter.
The present embodiment is a silicon base non ionic super spreader which reduces the surface tension of water The present embodiment is non toxic to plants. It reduces use of spreader by 50 %.lt improves the result of pesticides and fertilizers by 20-30%.So the quantity of chemical pesticides and fertilizers is small which results in considerable reduction in soil pollution and other adverse efforts on nature. As it is non ionic in nature and very stable at long temperature range, it does not react with other pesticides and fertilizers. So fertilizer capacity is kept intact and toxic harmful ingredients are not formed. So crop yield increases and it also reduces use of harmful chemical pesticides and fertilizers. This super spreader is a good dispersing agent, stable in cold water and have low toxicity to plants and animals.
The present embodiment is formed by acidification of polyether trisiloxane with EDTA (ethylene diamine tetracetic acid )at specific temperate in between 70 to 80° c where CMC point of silicon compound is achieved which act as super spreader of grade 8083, termed as- Visilon8083.
The chemical structure of silicon surfactant makes super spreading property compared with regular spreaders. The content of trisiloxane is the key which guarantees the

spreading ability. VISILON-8083 has the trisiloxane content 80%-85%, concentration 100%, it is a super spreading surfactant.
Agricultural silicon synergistic agent VISILON-8083 gives an aqueous surface tension of 20.5mN/m. After the mixture with the agrochemical solution at the certain proportion, the contact angel of spray solutions on leaf surfaces is reduced, leading to an increase in spray coverage.
Additional, VISILON-8083 promotes rapid uptake of agrochemicals into plants via stomata infiltration. Spray solutions taken into plants in this way become rain fast, thereby improving application reliability.
Best mode of performing the invention-
Many trials are carried out for the exact percentage of acidified polyether trisiloxane in visilion 8083.
Example 1
In first sample, 45% of polyether trisiloxane is taken for formation of visilion 8083 and when visilion 8083 is used as a spreader .It spreads 20 mm on leaf while its penetration in soil is 85 mm.
Example 2
In second sample, 65% of polyether trisiloxane is taken for formation of visilion 8083 and when visilion 8083 is used as a spreader, it spreads 35mm on leaf. It penetrates in soil about 130mm.
Example 3
In third sample, 85% of polyether trisiloxane is taken for formation of visilion 8083 and when visilion 8083 is used as a spreader, it spreads 35mm on leaf. It penetrates in soil about 130mm.
The percentage of polyether trisiloxane cannot be taken more than 85% because it spreads more at higher percentage will reduce sticking property of the product.(except

in some cases in which sticking is necessary to keep pesticide on p!ant).The spreading and soil penetration result achieved at 85% is more than sufficient for foliar and fertilizer applications. If more than 85%of polyether trisiloxane is used, it is costly.
Comparative study for fixing the application dose of super spreader visilion 8083 in percentage of fertilizer/pesticide used
This comparative study is carried out in the grape farm of farmer Mr. ajay dhakane,A/p-talegaon dindori.Tal -dindori.Dist-nashik.
Temperature: 24°C Average
Pesticide / Fungicide - COC (Cupper oxy chloride)
Additive - Visilon8083 as hitech super spreader
Observation Period - 10days . Daily twice a day.

Sample Area Fungicide Qty Visilon8083 Result/Control
Trial Area A as per label claim Nil 70%
Trial Area B as per label claim 0.05ml per lit 80%
Trial Area C as per label claim 0.1ml per lit 90%
Trail Area D as per label claim 0.2ml per lit 91%
Trial Area E as per label claim 0.3m! per lit 91%
Observation shows that even very small quantity of the visilion 8083 ,0.05 ml per litre increases the result of pesticide considerably but it reaches highest peak at 0.1 ml per litre but does not increases propionates at higher quantity and application of higher quantity may reduce sticking property of solution which is essential in some application of fungicides and pesticides.
So 0.1 ml per litre application dose of the present embodiment is correct and most economical.i.e. 10 ml per 100 lit of water.

This super spreader can be used through spraying as well as through drip irrigation and it never sprayed as single compound. It is always used with other agro inputs such as insecticides, pesticides and other groups so its individual effect does not count any measurable act on environments. The studies reveals that the formulated product does not leave any harmful residues in food or environment. As VISILON-8083 is not pesticide or fertilizers and its pH balances to near by 7 so it does not do any harm to environment as well as animals. This proves that this product is safe, even though it is a natural organic compound.
