Abstract

Formulation of black rice extract (Oryza sativa L.) microemulsion and evaluation of its anti-wrinkle effect in vivo have been investigated. The results showed that black rice extract microemulsion has composition as black rice extract of 4%, VCO of 28.8%, Croduret-50-SS of 28.8%, glycerol of 28.8%, and citrate-phosphate buffer pH 3.0 of 9.6%. The anti-wrinkle effectivity of black rice extract in microemulsion form was more than in emulsion form. The average decrease of wrinkle level by black rice extract microemulsion was 44.46%19.7%, and by black rice extract emulsion was 36.6%19.5%.
