Abstract

To meetout the growing consumer demand for cosmetic preparations that incorporate biologically active and natural ingredients, this study utilized lemongrass essential oil to create the main scent for body wash products in place of artificial fragrances on the market. Lemongrass essential oil is distilled by the method of hydrodistillation with the optimum yield of 0.29%. The process of developing a body wash formula is based on the survey of parameters affecting the product qualities. Multiple parameters including detergent, humectants, skin emollient, foaming agent, preservative, essential oil content were investigated. The product was evaluated based on the criteria of the foamability, the durability of the emulsion and the storage of samples in different storage conditions (room temperature, heat shock, acceleration). The results indicate that lemongrass essential oil body wash formulae are on par with some other shower gel products on the market, opening up the development trend for new research products to enter the market.
