Field of the invention:
The present invention relates mustard oil based hard surface cleaner formulation and the process for manufacture.
Background of the invention:
Cleaners, also known as wetting agents, lower the surface tension of a liquid, allowing easier spreading. The term cleaner is a compression of "Surface active agent". Cleaners are usually organic compounds that contain both hydrophobic and hydrophilic groups, and are thus semi-soluble in both organic and aqueous solvents. By lowering the surface tension of water, cleaners enable the cleaning solution to wet a surface more quickly, so soil can be readily loosened and removed (usually with the aid of mechanical action). Cleaners also emulsify oily soils and keep them dispersed and suspended so they do not settle back on the surface. To accomplish their intended jobs effectively, many cleaning products include two or more cleaners. Cleaners are also known as amphipathic compounds, meaning that they would prefer to be in neither phase (water or organic). For this reason they locate at the phase boundary between the organic and water phase, or, if there is no more room there, they will congregate together and form micelles. The concentration at which cleaners begin to form micelles is known as the critical micelle concentration or CMC.
Cleaners are also known as wetting agents. They may be liquids or powders. Cleaners are used in aqueous medium to provide detergency, emulsification, and wetting action. Cleaners used in aqueous cleaners are usually biodegradable. The various soils and parts used in the process and the concentrations of the cleaner affects biodegradability. Lowering the surface tension of the cleaning solution helps the solution drain from the part being cleaned. Cleaners have several roles: they modify or "wet-out" the surface being cleaned or the soil being
removed, and they help form an emulsion of solvent in water for cleaning or of soil in water for flushing away.
A large number of formulations for commercial cleaners and all of the hard surface cleaners are present which have acids, ethoxylates or triethanol amines. Contrary to the commercially available cleaners the cleaner of instant invention is contains oil-based gel in which oil is converted into fatty alcohols and its ionic concentration is increased by chelatins.

Detailed Description of the Invention:
For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
It will be understood by those skilled in the art that the foregoing general description and the following detailed description are exemplary and explanatory of the invention and are not intended to be restrictive thereof.
The instant invention provides for a process and formulation for obtaining mustard oil based hard surface cleaner for domestic application purpose. The process involves reaction of mustard oil with metallic salt to form fatty salt /salt of fatty acids in presence of alcohol (esterification) and water in the ratio of 1-20:0.1-15:1-20 respectively at a temperature from 50-100°C. The fatty alcohol obtained from step 1 is then mixed with di-amine salt of ammonia and sulphate of fatty salt of lauric acid and is set to second reactor number. In this reactor the temperature and pressure ranges from 50-110°C and 10-25 psi respectively. The reaction takes place for about SOminutes to 2 hour depending upon the alcohol gelation properties. The designed surface-active compound is having one end of lipophillic and other end of hydrophilic capacity. The complete process takes about 1hour-6hours for complete reaction process. The next step of this process is the aging of the cleaner. In aging process the atmospheric air is allowed to polymerize the liquid cleaner with a stirrer with addition of water in the ratio of 1:1-20. The time for aging of liquid takes about 20 minutes to 2 hours. The
cleaning efficiency of the formulation of present invention is 2-6 times more than existing commercial products.
In this process there are at least two reactors, one aging tank and three source tanks and a plurality of supply line and electric motors. The first reactor where mustard oil, alcohol and catalyst are added for making fatty alcohol the temperature and pressure remains between 50-110°C and 10-25 psi. At this stage the critical role of reaction is the working ratio of all the mentioned products and the time at which they are added to the base mustard oil. The next critical part of the reaction is the addition of ammonium salt and gelling agent. If the reaction takes place with minimum gelling agent and maximum ammonium salt it will become thin like water, now if the gelling agent is more then it will loose its cleaning efficiency and pH balance.
The aging process is a critical of all the processes, if maximum air is incorporated it the liquid it will turn white and will solidify, however if less air is incorporated it will remain in semi gel form.
The purpose of adding metallic salt to mustard oil is to enhance its etherification with alcohol and at the same time to make alcoholic soap with certain amount of moisture. The glycerol part of the oil remains dissolved in the entire phase and makes the liquid cleaner transparent and also prevents its solidifying. The role of ammonium salt is to increase its ionic concentration and balance the pH of the entire liquid.
The purpose of two reactors and one aging tank is to maintain the consistency and cleaning efficiency of the entire liquid. The first reactor has a stirrer with constant stirring ranging from 5-20 rpm, the second reactor also has a stirrer with 10-50 rpm and both the reactors have digital temperature control and also pressure safety control, which is adjustable.
There are at least three liquid source tanks and three solid source tanks. The liquid tanks contain mustard oil in one tank, ethyl alcohol in second tank and water in third tank. All these tanks are connected to a primary reactor through control pipeline where any pipe outlet can be diverted to any other side. All these tanks are fitted with pressure safety, pressure gauge and liquid leveler. The primary reactor is stainless steel body with acid and base resistant sheet, it has a stirrer with changeable RPM, it is fitted with digital temperature controller, pressure gauge and variable pressure safety. The temperature can be varied from 50-110°C; it is also fitted with liquid leveler. In this reactor mustard oil, alcohol and water is mixed and reacted and then transferred to reactor number two. The reactor number two is also a stainless steel body acid and base resistant. In this reactor volume makeup reaction is conducted, the reacted material from reactor one is mixed with water and other salts and gelling agents and heated at 50-100°C and then transferred to aging tank. The secondary reactor is fitted with digital temperature controller, pressure gauge and pressure safety. The aging tank makes the consistency of the entire liquid in gel form with the passage of time ranging from 30 minutes to 2 hours and is then packed.

The present invention will now be explained with the help of following examples for the purposes of illustration and are not to be construed as limiting the scope of the claimed invention.
Example 1
The hard surface cleaner is manufactured by first mixing mustard oil with any of the alcohol in the ratio of 1:1-10 and catalyst can be any metallic salt varying from 0.1-5% in percentage. After mixing these the whole mixture is then heated for almost 1-2hours. Water is added during the heating in the ratio of 1:1-15 of mustard oil. The mixture is further heated until a uniform transparent solution is formed. The solution is then taken into second tank where it is mixed with di-amine salt of ethylene, quaternary salt etc. in the ratio of 1:2-5% and lauryal sulfate of dodecyl, stearyl etc. in the ratio of 1:0.5-2%. The solution is again heated for 1/2-1hour at 60- 120°C. the whole mixture becomes transparent. Then the mixture is transferred to the aging tank where further alcohol and water is added to make-up the whole cleaner up to 3-times of it. The whole mixture is heated below 100 °C for 1-2 hour to form a gel by incorporating atmospheric air into it by constant stirring. The completed mixture is then cooled and packed in bottles
