Coconut Oil Based Low Temperature Hair Oil Formulations

Abstract

The coconut oil based hair oil solidifies in winter. To get Solidification Point (S.P.)below 50C &good oxidative stability, the interesterification with monounsaturated fatty acid group oils was planned. Thus coconut oil on interesterification with castor oil gave product of S.P. below 50C at optimum ratio (Table 2) using immobilized enzyme from Thermo-MycesLanuginosus (TLIM),. But the lower ratio of coconut oil in this formulation led us to evolve alternative methods. The melting points of methyl esters of coconut oil &of the products of interesterified coconut oils and liquid oils suggested us to go for trans-esterification and interesterification. Trans-esterification of coconut oil with methanol using chemical catalyst was experimented as per reaction conditions of Table 3 gave Methyl esters of 2°C S.P. though viscosity was low. So, it was interesterified with coconut oil(Table 3), detailed study is underway) to improve viscosity. The interesterified Castor Oil & coconut oil was re-interesterified with MECCNO & (IE, CCNO+MECCNO) (table 4), process optimized to get product with 75% coconut oil.
