Abstract

Sunscreen is widely used in cosmetics as protection to reduce or prevent damage caused by ultraviolet (UV) radiation from the sun. The formulation of sunscreen containing compounds to absorb and reflect UV light. One natural ingredient that has potential as sunscreen is galangal which has anti-UV properties. Galangal contains flavonoid compound which has a big role in warding off UV rays while it also contains other compositions that have an anti-UV such as phenolic, saponin, alkaloids and terpenoids. The purpose of this research is to determine the optimal composition and conditions of galangal extract and to determine the effectiveness of galangal extract as an ingredient in sunscreen. The sample is Alpinia galangal which was extracted by the microwave-assisted extract (MAE) method with ethanol as a solvent. The resulting extract is then used for sunscreen cream and physical tests and the effectiveness of sunscreens such as SPF and irritation tests. The results indicate that the yield obtained is around 5.5% with a composition of phenolic components around 31.49 mgGAE / g and flavonoids around 13.78 mgCE / g. For sunscreen cream by adding galangal extract has an SPF value of around 15 and is included in the high protection category and the physical properties are stable. In this study, it was concluded that galangal extract has anti-UV properties and the irritation test showed that sunscreen with galangal extract showed no irritation symptoms and was considered safe for use on normal skin.
