AN EMULSION FROM ALOE VERA

Abstract Aloe Vera pieces were first cleaned. They were cut into pieces and ground in a mixie. The Juice was then filtered through a nice cloth, Exactly 130 mL of the syrupy liquid was taken in a l000mL beaker for the preparation of the emulsion Since it is water soluble1, exactly 500mL of zero ppm (pH 3.54) water was added to it. Exactly 12.000 grams of powdered Sodium stearate (Stabilizer) and 15.000 grams of powdered Di-phenyl amine (Anti oxidant) were added. 20mL of castor oil (Plasticizer) was also added. The mixture was then heated. When the syrupy mixture was hot, 34.950 grams of Starch paste (Adhesive) was slowly added with constant stirring. Finally exactly 5mL of liquid ultramarine (colorant) was added. The above contents of the beaker was kept inside a Tempo' digital hot air oven(S.L.No.273.9.02) and was heated for an hour continuously at a constant temperature of 120°C. The Emulsion thus prepared was subjected to further analysis. Note : 1. Apart from Diphenyl amine, other antioxidants like urea and thiourea were also used. But they were not found to be useful. 2. An attempt was also made to use Palm oil as a plasticizer. But the sample of the Emulsion prepared was non sticky in nature when it was coated on the surface of a porcelain tile. So using of Palm oil was avoided. 3. 15 grams of powdered Starch was dissolved in 20 ml of zero ppm water (Which weighed 19.950 grams) and was made as a paste. 4. Apart from ultramarine, red oxide powder was also used as a colourant.

CLAIM -I
We claim the following for the invention we have made which is titled as
“AN EMULSION FROM ALOE VERA”
Preparation of an Emulsion from Aloe Vera
An emulsion from Aloe Vera was prepared by adding the following compositions of various constituents of it.
1. Weight of Aloe vera juice (130mL) -139.048gms
2. “ water (500 mL) - 498.750“
3. “ Sodium stearate - 12.000“
4. “Di-phenyl amine - 15.000“
5. “ Starch paste - 34.95 “
6. “ Castor oil (20mL) - 19.54 “
7. “Ultramarine liquid (5mL) - 3.780“
Total Weight -723,068 gms
The method of preparation of this Emulsion is given in detail in the abstract.
Note :
1. The exact compositions of various constituents given above were found out only by the methods of trial and error.
2. Powdered Sodium stearate and powdered Diphenyl amine were used.
3. All the above constituents were accurately measured in Anamed digital balance model: MX -7205A.
4. Water with zero ppm was used throughout the preparation and analysis.
5. The pH of the zero ppm water was found to be 3.54
6. The pH of water was measured by Advantech digital pH meter after calibrating the meter with known solutions of pH 7 and 9.2.

ABSTRACT
Method of preparation of the Emulsion from Aloe Vera.
Aloe Vera pieces were first cleaned. They were cut into pieces and ground in a mixie. The Juice was then filtered through a nice cloth, Exactly 130 mL of the syrupy liquid was taken in a l000mL beaker for the preparation of the emulsion Since it is water soluble1, exactly 500mL of zero ppm (pH 3.54) water was added to it. Exactly 12.000 grams of powdered Sodium stearate (Stabilizer) and 15.000 grams of powdered Di-phenyl amine (Anti oxidant) were added. 20mL of castor oil (Plasticizer) was also added. The mixture was then heated. When the syrupy mixture was hot, 34.950 grams of Starch paste (Adhesive) was slowly added with constant stirring. Finally exactly 5mL of liquid ultramarine (colorant) was added.
The above contents of the beaker was kept inside a Tempo' digital hot air oven(S.L.No.273.9.02) and was heated for an hour continuously at a constant temperature of 120°C.
The Emulsion thus prepared was subjected to further analysis.
Note :
1. Apart from Diphenyl amine, other antioxidants like urea and thiourea were also used. But they were not found to be useful.
2. An attempt was also made to use Palm oil as a plasticizer. But the sample of the Emulsion prepared was non sticky in nature when it was coated on the surface of a porcelain tile. So using of Palm oil was avoided.
3. 15 grams of powdered Starch was dissolved in 20 mL of zero ppm water (Which weighed 19.950 grams) and was made as a paste.
4. Apart from ultramarine, red oxide powder was also used as a colourant.

CLAIM -II
1. Determination of pH of the Aloe Vera Emulsion
A small amount of the emulsion from Aloe Vera was dissolved in an optimum amount of zero ppm water (pH-3.54) and was made as a syrupy liquid. The pH of the emulsion was measured using a Advantech digital pH meter. The pH of it was found to be 9.49.
The pH value of the emulsion paint manufactured by Pidilite Industries Pvt Ltd, Bombay -59 ranges from 8.5 to 10 .Therefore pH values of the synthetic emulsion and emulsion from Aloe Vera are found to be identical with one another.
If the emulsion is acidic in nature (i.e., if it's pH value is below 7), it could not be coated on the walls of the houses because it would corrode the walls in due course. Hence the emulsion must be basic in nature and the pH value must be in between 7& 14. Since the emulsion from Aloe Vera is made alkaline (pH 9.49) it could be safely used to coat the walls of the houses.
2. Determination of stability temperature of the emulsion.
A known quantity of the emulsion prepared as above was placed in a beaker and kept inside the Tempo hot air oven, which was already maintained at a constant temperature of 150°C. The emulsion was kept inside the oven for an hour. It was then removed to find out whether there was any change in the original colour of the emulsion.
Since there was no change in its colour, the temperature of the oven was raised gradually. At an interval of every 10°C increase of temperature the emulsion was taken out and it was found that there was no change in the colour of it till the temperature was raised to 220°C. When the temperature was just
increased above 220°C the emulsion kept in the beaker started charring. The

colour of the emulsion was also blackened. Therefore it is inferred that the stability or withstanding temperature of the emulsion we have prepared is 220°C.
3. Observations.
Even after a lapse of a period of two years it is found that
a) There is no crack on the surfaces of the porcelain tiles coated with this emulsion.
b) There is no peeling on the surfaces of the porcelain tiles coated with this emulsion.
