FIELD OF INVENTION
This invention relates to the festival colours. More particularly, the invention relates to a non-explosive and non- inflammable organic composition of festival color powder.
BACKGROUND OF THE INVENTION
Festivals are celebrated all over the world. To celebrate joy of festivals, using colours is very common practice in India which has now spread in other countries as well. People make the celebrations colorful by sprinkling either colored flowers or colours in powdered or liquid form.
Apart from festival use, these colours can also be used in scientific use such as latent fingerprinting.
Commonly used term in India for festival colours is "GULAL". Hence further to this, the term GULAL or FESTIVAL COLOUR OR HOLI COLOUR OR COLOUR OR ABEER may be used in same sense. Another term is Vermilion but normally it is referred to only RED colour which the Indian women put in their hair partition to indicate their marital status. This is also a festival colour and is sprinkled during celebrations.
COMPOSITION OF FESTIVAL COLOURS:
1. Containing Flowers- Ancient colours were prepared using the flowers of Coral Trees. Advantage of using these were multiple such as their benefit to the skin. Slowly with growing civilization, this method of production became very tedious. Number of trees started reducing due to urbanization and thus the industrial scale production became very difficult.
Containing Chemicals- Developing Synthetic colours became the need of the hour to feed the demand of colours in the society. Hence use of dyes and chemicals produced by chemical methods became inevitable. For example while red colour is prepared by using mercury sulphate, black colour is lead oxide, green is copper sulphate and malachite green and blue colour is prepared with either prussian blue, indigo, cobalt nitrate, or zinc salts. And to give all these colours a shinier look, certain additives, such as glass particles and mica dust, are added but such colours, being toxic in nature, can cause irritation in skin and eyes, infections and allergies and can even lead to asthma.
Herbal Colours- Above problems led to a solution in the form of Herbal Colours from natural sources only. These colours use not only flowers but also colours available in our normal household use such as curcumin (Haldi) and Indigo (Neel powder) etc.

Further various commercial terms used for types of festival colours are as below:
- Non toxic colours Organic colour powder
- Food grade colour powder Cosmetic grade colour powder
- Neon colour powder etc.
Limitations of existing compositions of festival colours
Although the problems of using synthetic and chemical compositions have been overcome by using herbal, food grade or organic compositions, yet these herbal colours are made from flowers which are commercially grown by using pesticides and fungicides. Such harmful chemicals are not completely eliminated while making colours from these flowers.
Even more substantial underlying danger which is always existing in these colours is that they are EXPLOSIVE and INFLAMMABLE and can easily catch fire. After throwing the colour in air while using, a dust cloud is formed which contains Oxygen in it and when exposed to any source of ignition, it may explode like a bomb causing irritation to skin and eyes or even some serious injuries. One such incident was reported in TArWAN where the organizers threw the colour powder with the help of an electric blower, which created a huge dust color cloud that caught fire from cigarette being smoked in the party.
Hence a need was felt by the inventors to develop a composition of festival colours which is non inflammable, non-explosive and non-toxic too.

INNOVATIVE SOLUTION PROPOSED BY THE INVENTOR
The inventors of present invention have developed festival colours using additional ingredients other than corn starch to make the colours non- flammable, non- explosive and friendly to the skin. The choice of ingredients is based on their chemical compositions and their safe use on humans. Thus ingredients Corn starch, Tricalcium Phosphate, Sodium bi carbonate, Common Salt and Methyl paraben and their ratios are carefully selected.
OBJECTS OF THE INVENTION
The primary object of the invention is to disclose a composition of festival colours which is non-inflammable and non-explosive.
Another object of the present invention is to disclose a composition of festival colours which is friendly to the skin of the user.
Yet another object of the present invention is to disclose a composition of festival colours which can be easily removed from skin by using plain water.
One more object of the present invention is to disclose a composition of festival colours which is smooth in texture, has attractive aroma and has shining appeal to eye.
One more object of the invention is to disclose a composition of festival colours which is economical.
SUMMARY OF THE INVENTION
Normally Cornstarch is blended with Food grade dyes and water to make Gulal (HOLI COLOURS). In corn starch process, corn starch does not catch fire if comes in contact with ignite source directly. But when gulal is blown in air and it goes high in the air, this creates a dust cloud. This dust color clouds holds an ample amount of oxygen inside and when this cloud comes into

any ignite source, this gets a big blast. This blast may cause very severe harm to the people, playing with such kind of colours, and to stop such accidents, we have invented such a process which may not cause any harm to anyone playing with it on any occasion.
Present invention discloses a non-explosive and non- inflammable composition of festival color powder containing 60 % corn starch, 15 % Tricalcium Phosphate, 20% Sodium Bicarbonate, 4.9% NaCl and 0. l%Methyl Paraben. The dust color cloud of Corn starch which holds an ample amount of oxygen inside is contained due to the use of Tri Calcium phosphate, Sodium Bicarbonate, and NaCl which makes the composition non explosive even though it contains Corn Starch as used in earlier available festival colours.
BRIEF DESCRIPTION OF DRAWINGS NIL
DETAILED DESCRIPTION OF THE INVENTION
The following description is of the best-contemplated mode of carrying out the invention. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense.
Various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the claims. The specification and drawings are accordingly, to be regarded in an illustrative rather than a restrictive sense. Thus, without analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
The present invention meets the criteria of preparation of natural and non-flammable holi colours which will not affect health and will also prevent accidents happened due to artificial industrial colours.
Ingredients of the composition
The following table describes the composition and the ratios of its various ingredients

TABLE 1:
1. Corn starch- It is non- inflammable substance and does not catch fire when in contact with any of the ignite sources and also friendly to the skin and is non- explosive which passes the "GO/NO GO EXPLOSIVITY TEST".
2. Tricalcium Phosphate- It is a concentrated source of calcium, which may not cause any harm to the skin when used in holi colours and may also not cause any skin irritation and itching, also an inflammable substance.
3. Sodium bi carbonate- It is also one of the ingredient to be used which even if one intakes the colour while playing with it and so if accidently one consumes the colour, then also because of this ingredient, it will not harm anyone, as it contains such properties which makes its use as antacid to treat heartburn, indigestion, and upset stomach. Sodium bicarbonate is a very quick-acting antacid.
4. Common Salt- It helps to cleanse pores deeply, balance oil production and thwart bacteria that can instigate breakouts and acne. This is one of the skin friendly products and does not lead to any harm to the skin . This is also not considered to be inflammable.
5. Methyl paraben- It is an anti-fungal agent often used in a variety of cosmetics and personal-care products. It is also used as a food preservative and is generally recognized as safe by the USFDA for food and cosmetic antibacterial preservation. Methylparaben is readily metabolized by common soil bacteria, making it completely biodegradable. Methylparaben is readily absorbed from the gastrointestinal tract or through the skin and

so that it will not leave any bad impacts on the skin and will not lead to any bad reactions and infections which the other available cheap quality products are leaving on the skin of the people and also leads to irritation and itching.
Thus the advantages of using the above ingredients are as below:
• Non Toxic - It will not harm skin or the hair and also the environment.
• Non Explosive- Although the present invention also uses Corn starch which can form a cloud containing Oxygen yet it is non inflammable due to the presence of Tri Calcium Phosphate, Sodium Bicarbonate andNaCl.
• Safe to use- The composition of present invention has passed the safety test and EN71 certificate is issued after considering it safe and non -inflammable
• Easy to remove- These colours do not stick to the skin and are not be hard to remove from the skin once applied. One can wash them away simply with plain water.
• Available in shades- The colours are available in different shades, one may buy different shades depends on their choices and preferences which are available in different packaging of different sizes and shapes and also export of products manufactured in bulk quantity done.
Process of manufacturing
The process to manufacture Non-flammable/ non-dust explosive festival Color Powder (Gulal) is as below:
Step-1: Sourcing the Best quality Raw Materials
Raw Materials are the foundation of the finished products. As such they must meet the regulatory requirement and the specifications that contribute to the functionality and quality of the process and product for ensuring best finished products.
Due to increased access to unique and complex materials and global sourcing, choosing and buying best quality raw material is now tough task. It is very important to select the appropriate raw materials based on the functionality.
Step- II: Testing of raw material
The raw material collected for manufacturing the finished product, i.e., Gulal, are first tested, as Quality assurance is the crucial part of producing products that meet their specifications, we have

many systems that work together to ensure that our finished product meet and/or exceed their specifications. All the testing of the raw materials is conducted in In house lab before processing for the manufacturing of the Finished Product and by ensuring that all needed testing is completed, the raw materials then, processed for the manufacturing of Gulal.
Step- III: Blending
After the testing of raw material used for the manufacturing of Gulal, then all the ingredients essential for the manufacturing of Gulal like Cornstarch, Tri calcium phosphate, Sodium bi carbonate, Common Salt, Methyl paraben are blended with 20% demineralized water and FDA Certified dyes to form a consistent thick cake after the blending.
Step- IV: Drying
The prepared mixture is then left to dry with the help of the automated drying machine at a temperature of 90 to 110 degree centigrade.
Step-V: Grinding
This dried material is then grinded using specific grinder machine to achieve a uniform particle size, preferably 13-16 microns of the festival colour powder such that if blown in air it does not hurt anyone in eyes or cause irritation in skin.
Step- VI: Packaging
After grinding, Gulal i.e., Holi colour powder comes into its proper powder form. Strict inspection of finish goods the products is done and the colours are ready for packaging in air tight sealing. The finished product are weighed and sealed in moisture proof food grade poly bag then packaging of the product is to be done into the required size of packets as per the demand. Manual Packaging has also been done for less quantity of products to be sold.
Hence the NOVELTY of the present invention lies in disclosing a composition of festival colours which is nontoxic, non-inflammable and non-explosive. Only five easily available ingredients are taken in adequate and well thought of ratios. No other similar festival colour composition is available in any existing patents. Hence the inventors claim NOVELTY.
The choice of ingredients is made such that the effect of corn starch powder when blown in air is negated. Although corn starch itself is not flammable but when blown in air, it forms a cloud capturing good amount of oxygen within, which makes it explosive when exposed to any ignition source. Inventors have solved this problem in an innovative manner by adding Tri claim phosphate, Sodium Bicarbonate and NaCl which due to their fire resistant properties, consumes the oxygen present in the cloud and thus the festival colour becomes non explosive. Thus the invention duly qualifies for INVENTIVE STEP

Regarding Industrial application, the present invention is applicable in industry as it can be made at commercial and industrial scale and has a demand in the world over. It is easy to manufacture as ingredients are easily available in bulk quantities. Thus the invention duly qualifies for INDUSTRIAL APPLICATION as well.
