Abstract

The skin of the  pear (pyrus bretschneideri) contains f  lavonoid compounds which are efficacious as antioxidants,  which are able to inhibit or prevent oxidation of the substrate caused by free radicals. Pear peel extract can  be used as a repellent or antioxidant so that it can be developed into an antioxidant lotion. To maintain the stability of pear peel extract in the form of lotions, it is necessary to formulate appropriate lotions. The purpose of this study was to find out the lotion formulation of the active ingredient oleum rosae to find out the results of the evaluation carried out on the pear peel extract lotion. The method used is experimental using 6 lotion formulations with a concentration of pear peel extract of 3 and 4%, vitamin C variations of 2, 4, and 6%. The results of the lotion from pear peel extract were evaluated for 1 week. Ephysical quality valuation includes organoleptic test, pH test, vit amin C content test. From the results of the study, lotions with the formulation F4 are the best preparations, namely a slightly viscous dosage form, soft texture, white color, oleum rosae fragrance, homogeneous, stable at pH 6 and dispersion power 5-7 cm. The conclusion of the study is that pear peel extract can be made lotion preparations with a wide variety of concentration variations. Keywords: lotion, pear peel (Pyrus bretschneideri), physical quality

Abstract

Hand body lotion is a cosmetic used to moisturize skin in order to reduce dehydration. The coffee extract contains bioactive compounds that can provide high antioxidant activation. The purpose of this research is to study the effect of concentration on coffee extract and the addition of olive oil on organoleptic, hedonic, pH, and dispersive properties and to determine the value of the Sun Protection Factor (SPF) in the lotion. The research method involved extracting coffee grounds, heating the oil and water phases to 65°C, and mixing the two phases till it becomes an emulsion. Then add the oil and water to the mixture. The lotion that’s already in the container is ready for testing. This research used 8 formulas with coffee extract concentrations of 2% and 4%, and variations of olive oil from 0, 1, 2, and 3%. Organoleptic and hedonic tests were tried out on 25 respondents for 2 weeks. The pH test was carried out using a universal indicator. The spreadability test was carried out using a petri dish and the SPF test using a UV-visible spectrophotometer. The results showed that 25 respondents preferred formula 4 over the rest, which was white in color, thick in texture, soft scent and the aftertaste was moisturizing. All formulas have good spreading ability and all in the pH range of 5 – 8. The SPF test results were obtained for each formulation in the range of 6.78 – 12.95 and the highest SPF value was owned by F8 of 12.95.
