Abstract
Cosmetic products vanishing cream and soap were produced using oil from Desmodesmus ultrasquamatus as base mixture and addition of oil from Michelia champaca L. The saponification value of algae oil was estimated to be 210 mg/gram. Formulation of soap using minimal ingredients of algae oil, potassium hydroxide (KOH) and water was determined using this saponification value. Gas Chromatography Mass Spectroscopy helped in identification of fatty acid like 7, 10, 13-Hexadecatrienoic acid; 9, 12, 15-Octadecatrienoic acid; Stearic acid of algae oil and potentially active components like stigmasterol, β-sitosterol, Campesterol, Vitamin E from Michelia champaca L. oil. These compounds are effective for UV protection and are good anti-oxidants. Shelf life these active components for their antibacterial activity was checked using agar cup method on Escherichia coli, which showed a decrease in positive activity till 2 months from preparation. Vanishing cream preparation using coconut and algal oil was compared with changes in composition with respect to borax, KOH and water. The study aims to highlight use of algal oil as alternative for cosmetic production industry with use of natural oils from plants like Michelia champaca for their health benefits.
