Physico-chemical characterization of essential oils of Rosa indica and its application in hand sanitizer

Abstract

Ab ract. This research work documents the isolation, physical and chemical characterization of essential oil of Rosa indica L. and its application in hand sanitizer. R. indica essential oil (REO) extracted from freshly illation method showed 0.057% yield. Some of the physical gravity (0.92), optical rotation (optically active), acid number (14.10), e er number (28.19), consi ency were determined in laboratory using compounds belong to eight major groups. Monoterpene alcohol represented the main characterized group (59%) followed by sesquiterpenes hydrocarbons (21.20%), phthalate e er (9.99%), aldehyde hydrocarbon (1.41%), alkyne hydrocarbons (1.21%), aromatic hydrocarbons (1.21%) and pyrozole derivative (1.21%). However, among the monoterpene alcohol, the 1-phenylethyl alcohol (13.02%); citronellol (10.01%) and 6-octen-1-ol, 3,7-dimethyl (9.55%) were found in mo abundant. Formulated hand sanitizer with REO exhibited physical and microbiological properties that were comparable with the market product. It also had pleasant scent, compatible with skin, easy to apply, and are acceptable to the users. The current udy clearly shows that REO could be utilized as a potential ingredient in hand sanitizer formulation for giving the pleasant smell, acceptable physical and microbial quality parameters.
