FIELD OF THE INVENTION
The present invention relates to an improved natural hair dye and method of preparing the same,
from natural ingredients.
The present invention particularly relates to a method of preparing natural dye by using
mordant, natural gum and gum binders and thus reducing the time for colour development. The
mixture of natural dyes derived from the method of present invention can be used in coloring the
hairs.
BACKGROUND OF THE INVENTION
The synthetic dyes used for coloring of hair have been known for many years. Colorants are classified as being temporary or permanent. In temporary coloring the color can be washed from hair relatively easily so called permanent coloring of hair, typically involves the formulation of aromatic diamine or hydric phenols polycompounds such as para phenylene diamine on the hair fiber but they are raising many side effects such as skin cancer, loss or damage of hair etc hence these synthetic dyes, which are used for coloring hair, are very toxic and thus hazardous to human health as well as to the environment.
To color human hair using oxidative dye technology, the hair is generally treated with mixture of oxidative hair colouring agents and an oxidizing agent. Hydrogen peroxide is the most commonly used oxidizing agent. However, in addition to oxidizing the oxidative coloring agents, hydrogen peroxide treatment of the hair can also solubilise and decolorize the colored melanin component in the hair, which can lead to undesirable hair qualities, such as brittleness and hair damage.
Thus, it would be desirable to develop a hair coloring composition which exhibit reduced quality in terms of fadedness and roughness, provides improved resistance to wash out during a daily devising regimen; can deliver substantially homogeneous consistent hair colour results throughout the hair, which has reduced irritant effect on skin which has reduced staining on skin, which has reduced adverse effects on the hair of the user and also to develop a convenient, eco-friendly and easy to use method for the delivery of such a hair coloring formulation to the hair.
Over the years significant efforts have been directed towards elimination of many problems associated with the dyeing of human hair. Various approaches to hair dyeing have been developed. These include direct action dyes, natural dyes and oxidative dyes. Composition of herbal dyes and hair coloring mordants can be used to deliver a variety of hair color to the hair. However, substantial improvement is needed in the areas of color saturation,

color development time, precise initial colours consistency, improved wash fastness, improved hair condition and level of hair damage.
A method of preparing herbal dye from plant is well known natural dyes and vegetable dyes included in the coloring compositions of the present invention such as Juglans regia, Indigofera tinctoria, Terminalia chebula, Acacia sinuata, Lawsonia inermis, Trigonella foenum-graecum, Sapindus mukorossi, Eclipta alba, and Embelica officinalis, dye extract. The method comprises extracting the dye using water and drying and now powder form of the dye t can be easily mixed with each other. The black dye prepared in this way is often used in coloring of hair. The method of obtaining dye from plant material is eco-friendly sound because water is used in the extraction.
Reference may be made to USSR certificate no. 1784623 (1992), wherein a brown dye of natural origin can be prepared from the rind of the ripe walnut. This dye is often used in the food -processing industry to stain confectionery products so that they resemble chocolate. However, this dye tends to degrade over time.
A black dye used in food products is derived from drying and refining tealeaves. Thus there exists a need for black dye produced from natural materials that may be used in wide variety of context including hair color products. There is additional need for a method of producing such a dye in high yield manner.
Reference may be made to US Patent 7186279, wherein a herbal dye has been reported by us having the following ingredients Juglans regia, Indigofera tinctoria, Terminalia chebula, Acacia sinuata, Lawsonia inermis, Trigonella foenum-graecum, Sapindus mukorossi Eclipta alba and Embelica officinalis, and Piper betel and mordants. But this dye has a problem of time taken in development of colour, which is approximately 24 to 48. This is a long time for colour development.
Reference may be made to Application no.01038DEL2008, wherein an improved dye which have variable colour development time and all ingredients of this dye is also not of natural in origin. Because some inorganic oxidizing agent like KMNO4 is used which solubilise and decolorize the colour melanin component in the hair which can lead to undesirable hair quality such as brittleness and hair damage and also prepared from two component in double packed so applying two times ,first component 1 and after short duration component 2. Thus there is a need for natural hair coloring compositions, which colour the hair effectively and avoid reduce damage to hair, irritation and or staining to the skin of the user. Thus the novelty of present invention lies in preparing natural dye by using mordant, additional gum and gum binders and thus reducing the time for colour development to 8-12 hours or overnight from 24-48 hrs.

OBJECTIVES OF THE INVENTION
The main object of the present invention is to prepare natural dye for coloring hair, which is made homogenous in application, non dripping, and prevents or/and reduce damage hair, skin irritation and staining of skin, dandruff, condition hair with over night (8-12 hrs) time of development.
Another object of the present invention is to prepare natural dye with addition of specific gums, gum binders and mordant in different ratio to better characterize the process, suspend, apply, development and stabilize the dye in terms of time and affectivity.
Yet another object of the present invention is to prepare a composition that has no side effects. Still another object of the present invention to provide a single pack fast acting hair coloring composition which is simple to use.

PLANTS USED AS DYE SOURCE ARE
Juglans Linn distributed in North and South America and from South Europe to East Asia. Six
species are known but here Juglans regia used in the context of the present invention. The rind
of unripe wild walnut is used as source material in the method of present invention. It is rich
source of proteins.
Indigofera tinctoria belongs to genus of leguminous plants originally native to India, China and
other tropical subtropical regions. The coloring matter is present in the leaves of the plant in the
form of indigotin also known as Indigo blue.
Eclipta alba a small genus of herbs distributed in tropical and subtropical regions of the world
one of mention above species occurs in India. The herb is used as tonic and skin diseases. It
contains a large amount of resin and alkaloidal principal ecliptine. The herbs also contain new
poly thienyl compound (alpha - terthienyl methanol) Beta - amyrin and Stigmasterol.
Emblica officinalis is indigenous to a large area ranging from the Southern Himalayas of Nepal,
North India to South India, Sri Lanka, Burma, Thailand, China and Malaysia . Fruits, barks and
leaves are rich source of tannin. Dried pulp of unripe fruits contains 18-30% tannin. Sometimes

even more (upto 35%) the fresh fruit is used for cooling, diuretic, laxative and stomachic. The fruit contains phyllemblic acid, lipids, gallic acid, pyrogallic acid and emblical. The seeds also contain fixed oils (Yield 16%).
Acacia sinuata is a common, princkly scandent shrub, occurring in tropical jungels throughout India. The pods known as shikakai, are extensively used as a detergent. A decoction of the pods relieves biliousness and acts as a purgative. It is used to remove dandruff. An ointment prepared from the ground pods is good for skin diseases. The pods yield saponins (20.6%). The alcoholic extract of the pods on acid hydrolysis gave a sapogenin, acacic acid.
Lawsonia inermis is a glabrous, much branched shrub or small tree with greyish brown bark. It is cultivated in many tropical and warm temperature regions. Large-scale cultivation for the sake of the leaves, which yield the dye, is confined to India, Egypt and Sudan and to some extent, Persia, Madagascar, Pakistan and Australia. Henna has long been used in India and Middle East Countries for colouring- palms of hands, soles of feet, finger nails and hair. It is harmless and causes no irritation of skin. Alcoholic extracts of henna leaves show mild antibacterial activity with 10.21% tannins, the tannin content appears to be variable, a sample from Jammu and Kashmir contained 4-5% tannin. The principal colouring matter is lawsone, 2-hydroxy-l:4 naphthaquinone which present in dried leaves. Besides lawsone other constituents present in henna are gallic acid, glucose mannitol, fat resin and traces of an alkaloids. Sapindus mukorossi a deciduous tree, native of China, Japan and India found in Himalayas from Himachal Pradesh eastwards and in Assam ascending to an altitude of c. 1500 m. The tree requires deep well-drained soil for optimum development. Fruits are credited with expectorant and emetic properties and are used in the treatment of excessive salivation, epilepsy and chlorosis. They are also reported to act as fish poison. Powdered seeds are said to possess insecticidal properties. Fruit is valued for the saponin (10%) present in the pericarp which constituent up to 56.5% of the drupe. A crystalline saponin mukorosside has been isolated from the pericarp. Extract of the pericarp mixed with DDT are used as a fungicide and insecticide. Trigonella foenum-graecum is an aromatic annual 30-60 cm in tall, found wild in Kashmir, Punjab and upper Gangetic plains and widely cultivated in many parts of India. Seeds are eaten, boiled or roasted as a vegetable in dyspepsia, diarrhea, and dysentery colic, enlargement of liver and spleen and chronic cough. A paste of the seeds is used as a cosmetic to keep the skin smooth and clean. Seeds contain alkaloid trigonelline, choline, saponin, gums, essential oil, fixed oil, bitter extractive and colouring substance is also used as gum.
Terminalia chebula is a large tree found in the sub Himalayas tract of west Bengal, Assam. It is also found in south India. Sri Lanka Burma and Malaysia. The dried fruits give natural dyes. It is very rich source of tannin (up to 30-35%). Myrobalans are used in fever, cough, asthma,

urinary diseases, piles and worms. The fruits contain about 30% of an astringent substance, which is due to characteristic principle chebulinic acid also contains tannic acid, gallic acid, resins and some natural anthraquinones.
The present invention is based on finding particularly effective methods for preparation of natural dye .The methods and products involve the use of a dye, gums, gum binders and mordants in specific ratio.
