Press Release Summary = Holi is a festival in India which begins on Duwadashi - on
the twelfth day of the waxing moon of the month of Phalgun. Phalgun arrives with the
promise of warm days and new life - Spring is the season of rejuvenation and
rebirth. Holi comes alive with the colours of 'gulal'. These gulal are made from
Chemical dye. Some of these chemical dyes are toxic, create allergic reaction to
skin. These chemical dye-based colours are prepared from toxic dyes such as
'Auramine (yellow), Malachite (green), Rodamine (orange), Methylene (blue) and a
blend of these colours which are harmful chemicals and beside it, this gulal also
contain sand, starch and salts which causes irritation in the eyes, skin allergies
and respiratory diseases. The starch used to make gulal are wasted quality, and so
it also creates problem to human health.

Scientist from the Industrial Toxicology Research Centre (ITRC) claimed
that the toxicity of synthetic colours could lead to problems like cancer
of the liver and urinary bladder, anaemia, allergies, disturbed organ
functioning and growth inhibition. Due to this problem of Chemical Gulal
on our body and eyes have forced us to do a turn-about to the natural
colors. A process is going at laboratory scale as well as in a pilot plant
at Chemical Engineering Department, Jadavpur University, Kolkata with
collaboration of Moromi (a NGO) where in spite of chemical dye, floral dye
are used. Flowers like Marigold, China rose, Butterfly Pea, Flame of the
Forest etc are used for the extraction of colourful dye. These dyes are
non-toxic, do not cause any harm to skin or to the face. The production of
herbal gulal is also very easy. The floral dye are extracted from
colourful flowers by aqueous extraction process of fixed flower – water
ratio. Then this dye is mixed with powder and a fixed amount of starch. The cost of the production is not so high and the procedure
is too easy so that village unemployed people also can earned money for their
survival. Depending on it a Large scale Industry also can set up.
