Intsia bijuga wood, also known as Merbau in Indonesian, is a commercial wood with high economic value primarily found in Indonesia. The study aimed to select the best extraction solvent and phytosome formulation for I. bijuga heartwood extract for topical antiaging cosmetics, taking into consideration antioxidant, antityrosinase, and sun protection factor (SPF) values. The results showed that 50% ethanol extract and phytosome formulation had promising antiaging properties, making them suitable for development as active ingredients in cosmetics.
Intsia bijuga (Colebr.) wood (Indonesian: Merbau) is commercial wood with high economic value and is most commonly found in Indonesia. Intsia wood extractives have biological activities related to their potential as natural active ingredients for antiaging cosmetics This study aimed to select the best extraction solvent and phytosome formulation of I. bijuga heartwood extract as an active ingredient for topical antiaging cosmetics. There were five and three variations on extraction solvent and phytosome formulation, respectively. Three main antiaging activity parameters, namely antioxidant, antityrosinase, and sun protection factor (SPF) values, were considered in selecting the best extract and phytosome formula. The results showed that 50% ethanol possessed good antioxidant and antityrosinase activity, but was lower in SPF value, which was significantly different than in other extracts. The phytochemical profile revealed robidanol and robinetin as the main constituent in five I. bijuga extracts. Phytosome F3 possessed high antioxidant, antityrosinase, and SPF values compared to other 50% ethanol phytosome extracts. It could be concluded that I. bijuga ethanol extracts and its phytosome are potent enough to be developed as an antiaging active ingredient in topical use cosmetics.
