FORMULASI KRIM TABIR SURYA EKSTRAK KULIT NANAS (ANANAS COMOSUS L MERR) DAN UJI IN VITRO NILAI SUN PROTECTING FACTOR (SPF)

Abstract

This research aims to determine the value of sun protecting factor (SPF) of pineapple skin
extracts (Ananas comosus L Merr) in the form of cream with variant concentration of 2%,
4% and 8%. The pineapple skin contains flavonoids and tannins substances that can give the
effect as a sunscreen. The formulation of pineapple skin extract cream using the phase of oil
in water. The ingredients that was use in the cream formulation are stearic acid, liquid
paraffin cera alba, cetyl alcohol, stearyl alcohol, propylene glycol, triethanolamine, distilled
water and nipagin. Cream of pineapple skin extract then giving a variety of specified quality
testing and SPF value. Each concentration cream diluted using 96% ethanol. Creams that has
been diluted read it’s absorbance value at UV-Vis Spectrophotometer instrument then
calculated the SPF values. The results showed that the cream of pineapple skin extract has
met the requirements after conducting various quality of cream tests and the SPF value of
each cream concentrations are very low. It’s been Concluded that the concentration of
pineapple skin extract cream 2% has shown a very small SPF value and increasing the
concentration of 4% and 8% demonstrate higher SPF values but still does not meet the
standards as a good sunscreen cream.
