Antioxidant Activity and Development of Hair Serum Containing Essential Oils From Pomelo Peel

Abstract

This research aims to 1) study the antioxidant properties of essential oil of pomelo peel, 2) develop hair serum products containing essential oil from pomelo peels and 3) evaluate the satisfaction of users of hair care serum containing essential oils from pomelo peels. The results of the research are presented below: -
In testing the antioxidant activity, the free radical scavenging ability at 50 percent (IC50) of Vitamin E was 133.28 ± 13.97g/ml. while of essential oil extracts from pomelo peels was an IC50 value of 1.10 ± 0.26g/ml. Development of hair in 4 formulas contained an essential oil in concentration levels of 0, 1, 3, and 5 percent. Result of stability test was examined by method Heating/Cooling cycle for 6 cycles at a temperature of 4 ºC and 45 ºC in accelerated condition. It was found that the pH values were 5.04, 5.56, 5.55 and 5.55 respectively. Formula 1 showed odorless. But the scent of essential oil from pomelo peel was found in the others. Testing for skin allergies using the closed patch test method, no allergic reactions were found in any of the volunteers. The results of testing satisfaction with the use of hair care serum in 20 volunteers, it was found that volunteers were overall satisfied with all 4 formulas at a high level. Arranged from highest to lowest, they are Formula 4, Formula 2, Formula 1, and Formula 3. The best and most satisfying formula is Formula 4. However, analyzing the results of satisfaction of hair serum had no statistically significant difference at the 0.05 level (p>0.05).
