Abstract
An antioxidant is a compound that can neutralize free radicals by donating elektrons to it. Antioxidant compounds can prevent damage from free radicals in normal cells, proteins and fats. A newly developed form of cosmetic preparation is a serum containing natural antioxidant. This study was an experimental laboratory research. The purpose of this study were to find out the good formulation, to make good quality standards for the physical evaluation of serum preparations and to identifiy of antioxidants activity categories in the Ipomoea carnea Jacq. leaves extract serum (Ipomoea carnea Jacq). I. carnea macerated by ethanol 96%. DPPH ((1,1- Diphenyl-2-Picrylhydrazyl) was a simple and fast method where it can be inhibited by moderate antioxidant on 139,71 ppm. The resulting formula (0) 360 ppm was obtained by having no antioxidant activity, formula I was obtained by the IC₅₀ value of 181,15 ppm of weak activity, formula II was obtained by the IC₅₀ value of 129,45 ppm moderate antioxidant activity and formula III II was obtained by the IC₅₀ value of 122,01 ppm was moderate antioxidant activity. In all four formulations they had moderate antioxidant activity and had a slightly viscoun texture, with green tea aroma, serum pH had met SNI standards and didn’tt show any irritations to the skin.
