Description:TECHNICAL FIELD

[0001] The present invention relates to the field of hair coloring compositions. More particularly the present invention relates to a liquid herbal hair dye Formulation coloring composition containing a decoction of a natural dye for applying to hair is disclosed in the present invention by using the plant species Woodfordia fruticosa.

BACKGROUND ART
[0002] The hair dye industry is one of the fastest-growing in the beauty and personal care industries since both men and women frequently change their hair color for the purpose of enhancing their youth and beauty as well as following fashion trends.
[0003] The hair colorant industry is a rapidly growing industry worth over $7 billion worldwide. In hair dyeing, different chemical compounds are used to treat the hair primarily for cosmetic purposes. People dye their hair regardless of their economic or educational status to emphasize the importance given on appearance.
[0004] The majority of dyes on the market for coloring hair are synthetic in nature and contain chemical properties that are toxic, allergic, or carcinogenic. Even though these synthetic dyes are inexpensive, they can be hazardous to human health over time. In addition, these synthetic products are unfriendly to the environment. Synthetic dyes are criticized for causing pollution in water and problems with waste disposal because they are almost always derived from coal. Chemicals used in synthetic dye production and use are released into the environment in large quantities. Human skin and health are adversely affected by synthetic dyes and other chemicals used during the manufacturing process. Numerous harmful health effects, particularly allergic contact dermatitis, have been linked to hair colouring products. Additionally, there has been evidence of its link with more severe and systemic diseases, such as cancer. Due to the negative consequences of synthetic hair dyes, it was deemed necessary to create a herbal dye composition with negligible or no negative impact on human health.
[0005] For centuries, color has been a key factor in determining the acceptance of textiles, cosmetics, food, and other products. The availability of natural dyes has increased due to a renewed interest in them. Eco-friendliness, non-allergic properties, and non-toxicity are some of the reasons why natural dyes are valued worldwide. Currently, herbal dye products are in high demand on the global market.
[0006] Natural hair colourants, as opposed to synthetic dyes, are not only simple to apply but also free from any unfavourable side effects.
[0007] ES2651270T3 A method for permanent hair coloring without the peroxide raw material ingredient, comprising the steps of: (a) providing a color base composition containing at least one primary dye intermediate chosen from ortho aminophenols, for aminophenols, ortho phenylenediamines, for phenylenediamines, double bases, heterocyclic bases, acid addition salts thereof and mixtures thereof; (b) apply the base color composition to the hair; (c) optionally, rinse the hair color base composition; (d) provide a developer composition containing at least one oxidizing agent selected from persulfates, perborates, percarbonates, their salts and mixtures thereof, wherein the developer composition does not contain hydrogen peroxide and contains no more than 1% by weight of water , based on the weight of the developer composition; and (e) applying the developer composition on the hair to develop a color, in situ, on the hair, wherein the developer composition is applied up to 60 minutes after application of the base color composition.
[0008] Therefore, the colour used in products for naturally colouring hair comes from organic sources. The dye manufactured from plant ingredients is a simple-to-use product that require no professional succor.

[0010] An object of the present invention is to provide a liquid herbal hair dye formulation employing the natural source Woodfordia fruticose.

[0011] Another object of the present invention is that it can be used for colouring the hair instead of synthetic hair dyes in order to avoid the downsides of synthetic colourants.

[0012] Yet another object of the present invention is to develop a herbal dye formulation which is natural, eco-friendly, non -toxic and non-allergic to the human skin and can be used safely for long period.

[0033] Methodology
Collection & Authentication of plant material
[0034] Field surveys were conducted to find out the populations Woodfordia fruticosa in Madhya Pradesh state. The flowers of the species were collected from the forest areas with the permission of Divisional Forest Officers and Range Officers of respective Forest Divisions and ranges. The plant specimen was authenticated by Forest Ecology and Climate Change (FE & CC) Division of Tropical Forest Research Institute, Jabalpur and Herbarium of the plant specimen was submitted in FE & CC Division (Accession no. 73).
Preparation of decoction of Woodfordia fruticosa flowers dye
[0035] Steps involved in preparation of decoction of dye are given below:
[0036] The flowers of Woodfordia fruticosa were collected, dried in shade, and powdered.
[0037] For standardization of optimal extraction method for natural dye from flowers of Woodfordia fruticosa, the dye extraction parameters material to liquor ratio (MLR), pH of extraction medium (water) and extraction time were optimized. First, dyes from flowers were extracted using neutral, acidic, and alkaline mediums, and optical densities of the dye extracts were assessed at absorption maxima 415nm which was obtained by screening the dye solution between 200 – 800 nm in UV- Visible spectrophotometer. The alkaline medium had been found to be the most profitable for floral dye extraction based on the highest value of absorbance. By changing one extraction parameter at a time while holding the other two constant, the aforementioned three extraction parameters were optimized, which was followed by an absorption measurement. The ideal material to liquid ratio (MLR), pH, and extraction time for extracting dye from flowers were determined based on the maximum value of optical density for a given set of experiments.
[0038] Response surface methodology (RSM) simplifies the number of experiments while also identifying the best process configurations to achieve maximum efficiency. In order to design the experiment, a Box-Behnken Design technique with three factors (variables) was chosen. Three process parameters—concentration (M/L ratio), pH, and extraction time—were used as input variables, and the dye's absorbance was selected as the system response. The lowest and maximum limits of each factor (duration ranging from 5 to 25 minutes, pH 2 to 8, and M:L ratio ranging from 2 to 14 g/100 mL) were entered into the model based on prior studies. Three levels of each factor were selected for the experiment in the current Box-Behnken Design, as detailed below:
(1) Material (2, 8 and 14 gm)
(2) pH (2, 5, 8)
(3) Extraction time (5, 15 and 25 minutes)
[0039] There were 45 runs (15 runs each with two genuine replicates) of various combinations created for this optimization. The design of dye extraction trials was followed while conducting the experiments. Absorbance was recorded and Optical density (OD) was calculated (Table 1).
[0040] The significance of effects of the factors was tested using Analyses of Variance (ANOVA). Both Linear and quadratic effects were tested along with the general effect (both linear and quadratic combined) of the factors. The statistical software STATISTICA was used for designing the experiment and analyzing the resulting data. By using analysis of variance, significant conditions were found in the model for response (Table 2A – C).
[0041] From the above experiments and using Box-Behnken Design, the optimized protocol for extraction of maximum natural dye from Woodfirdia flowers were found to be flowers powder – 14 gm, pH - 8 and extraction time – 25 minutes (Table 2D – E). Among the three pH medium used, the decoction prepared from flower powder in alkaline medium with pH 8 provided highest value of optical density (OD) indicating maximum extraction of natural dye. This may be a result of media's enhanced effect on floral phenolic extraction.
[0042] Based on the above optimized conditions, the natural dye was extracted by heating the 14 gm of flowers powder with 100 ml of distilled water, by maintaining a material to liquor ratio of 1 : 7 on water bath for 25 minutes. The dye solution was filtered through Whatman filter paper no. 1 and evaporated on rotatory evaporator under vacuum to get the concentrated form which was further lyophilized for 10-12 hrs to get the red brown dye. The optimized method of dye extraction resulted in maximum dye yield (19.85%) from Woodfordia fruticosa flowers.
