Utilization of Green Tea Extract on Anti-aging Cream with Butylated Hydroxytoluene (BHT) and Tertiary Butylhydroquinone (TBHQ): Physical Stability Aspect

Green tea ( Camellia sinensis (L.) Kuntze) is a potent natural ingredient with flavonoid content that can be used as an antioxidant and anti-aging for skincare products. The formula containing green extract usually formulated oil in water emulsion or cream. active components of are catechins which characterized less stable against oxidation. Therefore, it needed to add other antioxidants such ButylatedHydroxy Toluene (BHT) Tertiary–Butyl Hydroquinone (TBHQ) protect the product from degradation. aim this study was obtain physically antiaging cream formula. Each tested physical stability by measuring several variables including organoleptic, pH, relative density, viscosity, flow properties, well droplet size. Accelerated testing carried out 3 mo at 40 °C 75 % humidity. results found BHT more than TBHQ terms parameters density While only gave better both formulas remain mo. It concluded TBHQ.
