Abstract
Sunscreen preparations are cosmetic preparations used as a protection to reduce the impact of sun exposure whose formulations contain active ingredients to absorb or diffuse sunlight, especially in areas of ultraviolet and infrared wave emissions. One of the potential natural ingredients for a sunscreen is parijoto fruit (Medinilla speciosa Blume). It contains flavonoid compounds that are able to prevent the harmful effects of UV rays. The objective of this research is to find out the formula of sunscreen cream of parijoto extract that meets the good physical quality of cream and to find out the result of SPF value test of parijoto fruit extract as sunscreen cream preparation in Vitro. The design of the study was experimental research conducted in the laboratory. The sample used in this research was parijoto made into thick extract by maceration method. Further, the viscous extract obtained was made to be a sunscreen cream and then tested either its physical evaluation or calculation of SPF value. The results of this study indicate that the preparation of sunscreen cream of parijoto fruit extract included in the extra protection category with the value is 6.66 and can be made into the good and stable preparations. The sunscreen cream of parijoto fruit extract has good physical properties and also has activity as UV protection in vitro.
Highlights
Indonesia is a country with high exposure of sunlight
The extract of Medinilla speciosa was chosen as the material used for sunscreen cream formulation
The flavonoid compound found in the Medinilla speciosa fruit has been known to be able to give protection against the exposure of the sunlight it was determined to be the background of this research, concerning the preparation formulation of the sunscreen cream of the Medinilla speciosa extract
Summary
Indonesia is a country with high exposure of sunlight. Human beings need sunlight to create vitamin D which is very useful to the bones. The flavonoid compound found in the Medinilla speciosa fruit has been known to be able to give protection against the exposure of the sunlight it was determined to be the background of this research, concerning the preparation formulation of the sunscreen cream of the Medinilla speciosa extract. Some of them were that it was very effective in producing optimal active ingredients, and the polar solvent such as ethanol was the more effective solvent that could be used for the natural antioxidant extraction It was chosen as the cream preparation because of its spreading ability which was good for the skin, easy to wash with water, and delivers the good medicine (Voight, 1994). To identify the effectiveness for the preparation of sunscreen cream based on Medinilla speciosa ingredient, it was necessary to test the physical quality and in vitro testing of the SPF values of the sunscreen cream preparation which was carried out using the spectrophotometry of UV-VIS
