HERBAL BLACK DYE USED IN BEAUTIFYING THE HAIR AND ITS

APPLICATIONS

FIELD OF THE INVENTION

The present invention relates black hair dye and method of preparing the same, from natural materials. The mixture of dye derived from the method of present invention can be used in coloring the hair.

BACKGROUND AND PRIOR ART OF THE INVENTION

The synthetic dye used for coloring of hair has 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 fibre. But they are raising so many side effects such as skin cancer, loss or damage of hair, etc. So these synthetic dyes, which are used for coloring hair, are very toxic and thus hazards 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 fade provides improved resistance to wash out during a daily devising regimen; can deliver substantially consistent hair color 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 includes direct action dyes, natural dyes and oxidative dyes. Composition of herbal dyes and hair coloring mordents 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 precise initial colours consistency improved wash fastness, improved hair condition and level of hair damage.

Thus there is a need for natural hair coloring composition which effectively dye the hair but avoid or reduce damage to the hair which can colour the hair effectively and avoid reduce irritation and or staining to the skin of the user.

Thus it is another object of the present invention to provide single packed hair coloring composition, which is fast action simple to use.

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, lndigofera tinctoria, Terminalia chebula, Acacia sinuata, Lawsonia inermis, Trigonella foenum-graecum,

Sapindus mukorossi, Eclipta alba, Embelica officinalis, Acacia catechu and Piper betle etc dye extract. The method comprises extracting the dye using water and drying and powder form the dye that 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. '

A brown dye of natural origin can be prepared from the rind of the ripe walnut. Such dye is described in USSR certificate no. 1784623 (1992). This dye is often used in the food -processing industry to stain confectionery products brown so that they resemble chocolate. However, this dye tends to degrade over time. This dye cannot be used in hair because it is unsuitable for cosmetic such as hair color products.

A black dye used in food products is derived from drying and refining tea leaves. 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.
