FORMULATION OF LOTION FROM BLACK TEA EXTRACT (CAMELLIA SINENSIS LINNAEUS) AS SUNSCREEN
Objective: The goal of the project was to explore extracts from black tea leaves (Camellia sinensis Linnaeus) to prove it can give protection against ultraviolet rays (UV) in lotion preparation.
Methods: Black tea extract was made in sunscreen lotion in oil in water (O/W) type emulsion using a combination of PEG-8 and beeswax as emulsifying agent 1, and combination of cetyl alcohol, ceteth-20, and steareth-20 as emulsifying agent 2. Evaluation of lotion including phytochemical screening of black tea leaf extract, measurement of sun protecting factor (SPF) value of extract black tea leaves, measurement of SPF preparation lotion sunscreen extract black tea leaves, physical observation of preparation, qualitative preparation evaluation using thin layer chromatography (TLC) and lotion security testing have been done to ensure the quality of lotions.
Results: The result exhibited the effective SPF that was different to the sunscreen lotion F1, which contained 0.03% w/v and F2 which contain of 0.04% w/v black tea leaves extract with the point of SPF is 20.31 and 24.71 respectively. Both formulas fulfilled the requirements as lotion preparations and did not irritate the skin based on an irritation test on 20 volunteers.Conclusion: Formulas F1 and F2 can be applied as a sunscreen with good physical quality and is safe for topical use in lotion preparation.
