Ethyl alcohol and butyl alcohols were used for trans-esterification of the Coconut Oil using sodium methoxide chemical and Eversa Transform 2.0 Lipase enzyme catalysts. The sodium methoxide catalyst used was 0.4% for interesterification of the ethyl and butyl esters with coconut oil at115ºc for 1 hours. The Ethyl Esters (E.E.) obtained had 0°C Solidification Point (S.P.) and butyl Esters (B.E.) (-2ºC) S.P. by using chemical catalyst. The enzymatic Method resulted (-2ºC, S.P.) Ethyl Esters and (-5º C, S.P. ) Butyl Esters products. The ester-ester interchange reaction of Coconut Oil with E.E. and B.E. yielded the hair oil formulations of the required S.P. of below 5ºC at optimum ratio. The physical properties of the low temperature hair oil formulations were analysed and compared with the market samples of the leading brands of the coconut oil based hair oils for winter use.

INTRODUCTION Air pollution cause considerable harm to our hairs and scalp. Regular Hair Oil application can protect health of our hairs and scalp by keeping hairs and scalp moisturized. Hair oils also maintains scalp clean. Certain hair oils and especially addition of suitable essential oils keeps fungus away, help consistent hair growth. Hair oils make the hairs healthy and prevent hair loss along with the lubrication of hairs. Coconut oil helps hair lustre and imparts emollient properties and also the glow to skin. Certain hair oils viz. N. Sativa, Hemp Seed, Rice bran, Sesame, Castor, Coconut etc prevent hair loss also (15-20). Coconut oil is scientifically highly recommended hair oil due to its fatty acid composition and nutraceuticals present. Its low molecular straight chain fatty acids penetrate in to the hairs and scalp maximum in comparison to other available hair oils (2). Babassu oil and palm kernel oil, cohune and cupea oils belong to the coconut oil family and act almost similarly. Coconut oil is most easily able to fill the gap between hair follicles and stops the entrance inside scalp of the low molecular weight surfactants like Sodium lauryl sulphate (SLS), a major foam booster in shampoo if applied as massage oil prior to washing. SLS can dissolve hair proteins and weaken hairs. As such, repetitions for a long time can result in hair fall (3). The mono unsaturated fatty acids penetrate inside hairs and scalp slower and poly unsaturated fatty acids still slower and preferably after slight heating as compared to saturated and especially low molecular straight chain fatty acids (3). So, the
