Minyak zaitun memiliki aktivitas antioksidan dan sifat emolien yang dapat melembapkan serta melindungi kulit dari radikal bebas. Penggunaannya dapat diformulasikan dalam bentuk sediaan lotion dengan menggunakan basis gliseril monostearat. Penelitian ini bertujuan untuk menganalisis apakah sediaan lotion minyak zaitun memenuhi persyaratan viskositas dan diameter sebar sesuai standar. Penelitian ini menggunakan metode eksperimental dengan rancangan posttest only design. Sediaan dibuat dalam dua formula, yaitu F1 (lotion tanpa minyak zaitun) dan F2 (lotion dengan minyak zaitun). Pengujian diameter sebar dilakukan dengan tiga kali replikasi, sedangkan pengujian viskositas dilakukan dengan tiga kali repetisi pada setiap formula. Data dianalisis menggunakan SPSS 25 melalui uji normalitas dan homogenitas, kemudian dilanjutkan dengan independent sample ttest dengan tingkat kepercayaan 95%. Hasil penelitian menunjukkan bahwa diameter sebar F1 dan F2 masingmasing sebesar 5,58±0,13 cm dan 5,03±0,03 cm, serta viskositas sebesar 14.039 mPa’s dan 25.050 mPa’s. F1 memenuhi persyaratan viskositas dan diameter sebar, sedangkan F2 tidak memenuhi persyaratan viskositas karena melebihi batas yang ditetapkan. Penambahan minyak zaitun meningkatkan viskositas sehingga menurunkan diameter sebar. Kesimpulan Sediaan lotion minyak zaitun dengan basis gliseril monostearat memenuhi karakteristik fisik pada uji diameter sebar dan uji viskositas.

Green tea leaves contain alkaloid compounds, tannins, saponins, steroids or triterpenoids, flavonoids and polyphenols that can be used as antioxidants. The use of green tea leaves as an antioxidant can be facilitated by being made into lotion preparations. The purpose of this study was to determine the lotion of green tea leaf extract with varying concentrations of glyceryl monostearate meets the physicochemical requirements based on organoleptical testing, homogeneity, pH and diameter spread. The research method used Posttest Only Group Design. Extraction of green tea leaf powder using maceration method using 96% solvent. Green tea leaf extract was made into lotion preparations using glyceryl monostearate base with various concentrations of F1 (7.5%), F2 (10%) and F3 (12.5%). Organoleptic and homogeneity tests were analyzed descriptively while pH and spread diameter were analyzed using SPSS 25. Normality test used Shapiro-Wilk test and homogeneity test used Levene's test. If the data is normally distributed and homogeneous (Sig>0.05) then proceed with the One Way Anova test. If in the One Way Anova test there is a significant difference (Sig 0.05) then proceed with the LSD test. If the data is not normally distributed, the Kruskall Wallis test is performed. If in the Kruskall Wallis test there is a significant difference (Sig 0.05) then proceed to use the Mann Whitney test.

Lotion is a type of skin care cosmetic. Lotion can be formulated with the active ingredient vitamin E. Vitamin E has antioxidant properties. Vitamin E is made in lotion preparations to make it easier to use and comfortable on the skin. The aim of this research is to determine the physicochemical properties of vitamin E lotion preparations based on organoleptic test parameters, homogeneity, pH and distribution diameter.
This research uses an experimental posttest only control design method. The lotion preparation formula consists of a formula without the addition of vitamin E (FI) and a vitamin E formula (FII). The lotion obtained was subjected to physicochemical evaluation including organoleptic tests, homogeneity, pH and distribution diameter. The data from the organoleptic and homogeneity tests were analyzed descriptively, while the pH and distribution diameter were analyzed using SPSS 26. The analysis began with a normality test and a homogeneity test. Data that is normally and homogeneously distributed is followed by an independent t-test, while data that is not normal and homogeneous is analyzed using Mann Whitney.
