Objective: The purpose of this study was to develop a nanoemulgel containing vegetable oil of carrot seed oil as an effective natural sunscreen and skin anti-aging. Methods: Nanoemulgels containing 4% carrot seed oil were formulated in three formulas with different ratios of Tween 80 and Sorbitol and prepared by using the high-energy emulsification method. The nanoemulgels were determined for the organoleptic characteristic, globule size, pH, physical stability during storage for 12 w at three different temperatures (room, high and low temperature), centrifugation, and cycling test. The Sun Protection Factor (SPF) value was determined by UV spectrophotometric method and the effectiveness of anti-aging was evaluated by using a skin analyzer and the results were compared with sunscreen emulgel. Results: Nanoemulgel containing 4% carrot seed oil with a ratio of Tween 80 as surfactant and Sorbitol as co-surfactant 40 and 20 resulted in the smallest mean droplet size of 338.34 nm and the sizes were increased during 12 w of storage at room temperature but still in the nano size and this nanoemulgel did not show phase separation or still stable. These nanoemulgels were also stable after the centrifugation and cycling test. The emulgel preparation was not stable or showed phase separation after the centrifugation test. The SPF value obtained from the nanoemulgel was 20.28±0.22 and these values were higher than the sunscreen emulgel (13.94±0.27). The pore size, spot, and wrinkles of the volunteer skin were reduced after using the nanoemulgel containing 4% carrot seed. Conclusion: The sunscreen and skin anti-aging activity of nanoemulgel preparation containing 4% carrot seed oil with a ratio of surfactant Tween 80 and co-surfactant Sorbitol 40 and 20 were more effective compare with emulgel preparation.

Umbi ubi jalar ungu (Ipomoea batatas (L.) Lam.) dan beras putih (Oryza sativa L.) diketahui memiliki aktivitas antioksidan. Penelitian ini bertujuan untuk membuat sediaan krim lulur scrub dari ekstrak etanol ubi jalar ungu dan mengetahui formula yang paling disukai. Umbi ubi jalar ungu diekstraksi dengan pelarut etanol 70% hingga menjadi ekstrak kental. Ekstrak kental tersebut kemudian diformulasikan menjadi sediaan krim lulur scrub yang terbagi atas 3 formula dengan variasi konsentrasi ekstrak  yaitu konsentrasi 2% (FI), 4% (FII) dan 6% (FIII) yang masing masing formula ditambahkan serbuk beras putih sebagai bahan scrub. Evaluasi krim lulur scrub meliputi evaluasi mutu  fisik (uji organoleptis, homogenitas, tipe krim, daya sebar, viskositas, sifat alir), uji pH, uji stabilitas dipercepat dengan metode cycling test dan uji hedonik (aroma, tekstur, warna, kesan lengket). Hasil evaluasi mutu fisik dan uji stabilitas menunjukkan krim lulur scrub yang diperoleh memiliki mutu dan stabilitas fisik yang baik. Hasil uji hedonik menunjukkan formula I merupakan formula yang paling disukai.

AbstractGreen tea is a plant that contains antioxidants. The content of green tea compounds that act as antioxidants are polyphenols. The addition of natural antioxidants in hydrogel masks has the potential as an alternative to synthetic antioxidants. The purpose of this study was to determine the antioxidant activity of the hydrogel mask preparation of green tea (Camellia sinensis L.) ethanol extract. The method of determining antioxidant activity was carried out by the -Carotene Bleaching (BCB) method. The stability test of the preparation using the cycling test method was carried out for 6 cycles including organoleptic, viscosity, pH, homogeneity tests. The data obtained from the antioxidant activity test is the IC50 value. The IC50 results of the green tea ethanol extract were 27,162 ppm, while the IC50 values for the formulations 1, 2 and 3 were 40,893 ppm, respectively; 35,348 ppm; and 32,270 ppm. The results of the stability test showed that the preparation was stable from the parameters of viscosity, pH and homogeneity but not stable from the organoleptic parameters because there was a color change in the preparation containing the extract after the cycling test process. In conclusion, both extracts and hydrogel mask preparations contain high antioxidants with relatively stable dosage forms.Keywords: Green Tea, Antioxidants, Hydrogel Mask, -Carotene Bleaching (BCB), IC50.
