DESC:FIELD OF THE INVENTION
The present invention relates to a cooling hair oil composition. More particularly the present invention relates to an herbal cooling hair oil composition with enhanced cooling effect and relaxation and strengthens hair follicles promoting hair growth.

BACKGROUND OF THE INVENTION
Healthy hair is considered as an important factor reflecting the good health of a person. In Indian tradition, hair oiling is a long-standing custom that has been passed down through the centuries for getting healthy hair. Hair oiling helps in utilizing the regenerative powers of natural oils by working them into the scalp and hair for moisture, nourishment, reducing dryness and hence providing hair with strength, shine, thickness, and softness. Hair oiling also helps to exfoliate, moisturize, and improve circulation in the scalp.

Healthy hair is considered as an important factor reflecting the good health of a person. A variety of hair problems arise throughout the summer, as the hair are exposed to harmful UV rays, heat, humidity and sweating in summer.

Various cooling hair oil for summers are available in the market which provides cooling effect during and after application of the cooling hair oil. However, it has been observed that said cooling hair oil provides cooling effect only for a short period of time and the cooling intensity is also low.

Hence, there remains a need for an improved cooling hair composition which provides an improved cooling effect in terms of cooling intensity, relaxation effect for longer duration of time, fragrance intensity and provides other benefits of a regular hair oil composition like strengthening hair follicles, promoting hair growth and making hair shiner and lustrous.

Likewise, the terms "include", "including" and "or" should all be construed to be inclusive, unless such a construction is clearly prohibited from the context. However, the embodiments provided by the present disclosure may lack any element that is not specifically disclosed herein. Thus, a disclosure of an embodiment defined using the term "comprising" is also a disclosure of embodiments "consisting essentially of” and "consisting of” the disclosed components. Where used herein, the term "example," particularly when followed by a listing of terms, is merely exemplary and illustrative, and should not be deemed to be exclusive or comprehensive. Any embodiment disclosed herein can be combined with any other embodiment disclosed herein unless explicitly indicated otherwise.
The present invention provides a cooling hair oil composition exhibiting the properties of enhanced cooling effect, relaxation, darkening of hair and promotion of hair growth upon continuous use of the hair oil by the user.
The present invention provides a hair oil composition comprising a vegetable oil comprising herbal decoction, additional herbs, mineral oil, antioxidant, fragrance (Sughandhit dravyas), cooling actives, optionally coloring pigments and other required agents for different functions.
The hair oil composition of the present invention comprises an herbal decoction comprising different herbs incorporated for providing the cooling and warming benefits. Cooling actives are also introduced in the hair oil composition to boost the cooling sensitivity.
Vegetable oils are excellent hair conditioners. They can penetrate the hair shaft, nourish the hair from within and smoothen the raised cuticles for softer and smoother hair. Vegetable oil is also beneficial for maintaining and moisturizing processed and colored hair. The vegetable oil is preferably selected from a mustard oil, a rice bran oil, a coconut oil, an olive oil, a sesame oil, a palm oil, a sunflower oil, an almond oil, an argon oil or a mixture thereof. Vegetable oil is preferably present in a range from 20 to 50% by wt. of the composition. It has been observed that when vegetable oil is present in high concentration the obtained hair oil gives user a stickier feeling and too low concentration of vegetable oil does not give the desired amount of nourishment to the hair and the hair oil rheology is not desirable. Preferably, the vegetable oil suitable for the present invention is rice bran Oil.
Mineral oils are clear oily liquids obtained from petroleum oil, from which waxes have been removed, and the more volatile fractions removed by distillation. The fraction distilling between 250° C to 300° C is termed mineral oil, and it consists of a mixture of hydrocarbons, in which the number of carbon atoms per hydrocarbon molecule generally ranges from C10 to C40. Mineral oil may be characterised in terms of its viscosity, where light mineral oil is relatively less viscous than heavy mineral oil.
In an embodiment of the present invention, the mineral oil preferably comprises light liquid paraffin oil (LLPO). Light liquid paraffin oil is a clear and odourless oil. The light liquid paraffin oil increases hair thickness and promotes growth as well. Its conditioning properties make it ideal for maintaining the texture and shine of hair. The LLPO is preferably present in a range of 50 to 80% by wt. of the composition. The LLPO concentration is suitably selected to balance the stickiness often encountered with high concentration of vegetable oils. It has been observed that using a concentration of mineral oil (LLPO) higher than the said amount range makes the composition "too-light" where the consumers find the composition to be very free-flowing. Using a concentration of mineral oil (LLPO) lower than the said amount range makes the composition suffer from stickiness which is one of the problems which is sought to be solved by way of the present invention.
The hair oil composition comprises fragrance. Fragrance may be in form of Sughandhit dravyas (Fragrance concoction) present in a range from 0 to 3% by wt. of the composition. A person skilled in art is well aware of the fragrances or fragrance concoction suitable for use in the present invention. Any fragrance or fragrance mixture can be used in the hair oil composition of the present invention provided that it does not alter the properties of the hair oil composition. Suitable fragrance known in the art are but no limited to lavender, rose, tea tree, jasmine, ylang ylang, lemongrass, peppermint, rosemary and other commercial fragrance mixtures.
The hair oil composition of the present invention comprises cooling actives like menthol (pudina satva), ethyl menthane carboxamide, camphor and thymol. The cooling agents are present in the base oil in a range from 0.001% to 20% by wt. of the composition.
The compositions of the present invention may comprise of other ingredients which are usually used in hair oil formulation. These other ingredients may include coloring agents such as Quinazarine Green SS (CI 61565), Cos Oil Toney Red (CI 26100), and Quinoline yellow antioxidants such as Tertiary Butyl Hydro Quinone (TBHQ). Other ingredients may be added in a range from 0.01 to 5% by wt. of the composition. A person skilled in art knows these ingredients and is aware of the said ingredients use in a hair oil composition in an amount effective to accomplish its purpose.

Example 1: Process for manufacturing cooling hair oil composition
The cooling hair oil composition of the present invention is prepared by process comprising following steps:
Step 1: Preparation of herbal decoction: The required herbs listed in table 2 except cardamom oil, coriander oil, Pudina Satva and camphor are powdered to required mesh size. A predefined amount of powdered herbal mix is taken in a suitable container, and DM water is sprinkled in required amount followed by mixing by hand for 30 min. The powdered herbs are allowed to get conditioned for approximately 2 hrs.
Step 2: Required amount of vegetable oil is charged in the main vessel fitted with a stirrer and antioxidant is added and mixed well. The temperature of oil is increased to 45° C and conditioned powdered herbs from Step 1 are added. The temperature is maintained at 60-65°C with continuous stirring for 30 mins. This is followed by increasing the temperature of the oil to approx. 102°C under a controlled process. The temperature of the oil is maintained at 102+/-2°C with continuous stirring to remove the moisture of the oil. After this the temperature of the resultant oil is lowered to around 45°C under stirring. The oil obtained is tested for in-process quality checks.
Step 3: The oil from Step 2 is mixed with Mineral oil and cooling agents like menthol.
Step 4: In a suitable SS vessel coloring pigment, Sughandhit dravyas, cooling actives Ethyl Menthane Carboxamide, thymol, kapoor (Camphor) etc. are mixed and the mixture is transferred to Step 3 oil mixture followed by addition of cardamom oil and coriander oil under stirring.
The hair oil obtained is filtered through a sparkler filter and is checked for quality testing.
