Abstract

Coffee grounds are residues from brewing coffee powder with hot water, and their utilization remains limited. This study aims to develop a cream scrub based on coffee grounds with additional chemical ingredients such as stearic acid, cetyl alcohol, olive oil, TEA, glycerin, phenoxyethanol, vanilla fragrance, and propylene glycol. Two formulations were developed with different concentrations of coffee grounds: 2.4% (F1) and 3.9% (F2). The tests included pH analysis, water content, spreadability, homogeneity, Total Plate Count (TPC) testing, and organoleptic evaluation. The results showed that the cream scrub had a pH of 6, with water content of 52.3% for F1 and 46.5% for F2, and a spreadability of 5 cm. Both formulations were homogeneous without phase separation. Moisturizing tests scored 4 (good), with F1 achieving 53.3% and F2 46.7%. The aroma of F1 scored 4 (good) at 66.7%, slightly higher than F2 (63.3%). In terms of texture, F1 obtained 66.7% at a score of 4 (good), while F2 reached 56.7%. The color parameter of both formulations was similar, with a score of 5 (very good) at 26.7%. Irritation tests showed negative results for 93% of participants for F1 and 96% for F2.

Abstract

Bidara leaves (Ziziphus mauritiana) contain active compounds such as flavonoids, tannins and saponins which function as antioxidants and antibacterials for healthy skin. This research aims to develop a body lotion formulation made from bidara leaf extract with tests including phytochemical, pH, spreadability, homogeneity, water content and organoleptic tests. Phytochemical results showed the presence of flavonoids, alkaloids, terpenoids, saponins and tannins. Three formulations were tested with different concentrations of bidara leaf extract, namely F1 (1%), F2 (3%), and F3 (5%). Test results show that the pH of all formulas (F1: 5.7; F2: 5.5; F3: 5.4) is within the SNI standard range (3.5–8.0). Spreadability decreases as concentration increases, namely F1 (7 cm), F2 (6.4 cm), and F3 (5.7 cm). All formulas met the homogeneity criteria, while the highest water content was found in F1 (49.05%) compared to F2 (26.3%) and F3 (25.6%). Organoleptic tests show that aroma resistance reaches 100% and there is no irritation in all formulas. The preferred aroma was higher in F3 (63.3%) compared to F2 (46.7%) and F1 (43.3%). Fragrance levels were similar for F1 and F3 (53.3%) as well as F2 (50%). The preferred humidity was highest in F2 (53.3%) followed by F3 (50%) and F1 (33.3%), while the permeability was highest in F3 (50%) compared to F1 (43.3%) and F2 (40%).
