Abstract

Rice abrasive merupakan alternatif bahan eksfoliasi alami yang ramah lingkungan untuk produk perawatan kulit, namun memiliki daya serap air tinggi sehingga memicu resiko kontaminasi mikrobiologi. Penelitian ini mengevaluasi pengaruh variasi konsentrasi dan jenis wax, terhadap karakteristik fisik dan kemampuan penyerapan air rice abrasive. Tujuh formula disiapkan F0 (kontrol), F1–F3 dengan cetyl alcohol (1%, 5%, 10%), dan F4–F6 dengan cetyl stearyl alcohol (10%, 20%, 30%). Evaluasi mencakup distribusi ukuran partikel, densitas sejati, laju alir, sudut istirahat, kompresibilitas, dan daya serap air. Formula terbaik diuji mikrobiologi dan morfologi SEM. Hasil menunjukkan F1 (cetyl alcohol 1%) memiliki kinerja optimal dengan distribusi partikel dominan 180–150 μm, densitas sejati 1,22 g/mL, laju alir 6,10 detik, sudut istirahat 10,75°, kompresibilitas rendah (10,37%), serta penurunan daya serap air sebesar 10,3% dibanding kontrol. Peningkatan konsentrasi wax justru menurunkan kualitas, sementara cetyl stearyl alcohol menghasilkan densitas tinggi namun laju alir lambat dan kurang efektif. Uji mikrobiologi F1 memenuhi standar BPOM (ALT dan AKK < 10³ CFU/mL), dengan SEM menunjukkan lapisan coating merata. Disimpulkan, cetyl alcohol 1% adalah formulasi optimal yang memberikan karakteristik fisik terbaik, daya serap air terendah, dan memenuhi standar keamanan mikrobiologi. ----- Rice abrasive is an eco-friendly natural exfoliating material for skincare products; however, its high water absorption increases the risk of microbiological contamination. This study evaluated the effect of varying concentrations and types of wax on the physical characteristics and water absorption capacity of rice abrasive. Seven formulations were prepared: F0 (control), F1–F3 with cetyl alcohol (1%, 5%, 10%), and F4–F6 with cetyl stearyl alcohol (10%, 20%, 30%). Evaluations included particle size distribution, true density, flow rate, angle of repose, compressibility, and water absorption. The best formulation underwent microbiological testing and SEM morphological analysis.Results showed that F1 (cetyl alcohol 1%) exhibited optimal performance with a dominant particle size distribution of 180–150 μm, true density of 1.22 g/mL, flow rate of 6.10 seconds, angle of repose of 10.75°, low compressibility (10.37%), and a 10.3% reduction in water absorption compared to the control. Higher wax concentrations reduced quality, while cetyl stearyl alcohol produced higher density but slower flow and lower effectiveness. Microbiological testing confirmed that F1 met BPOM standards (ALT and AKK < 10³ CFU/mL), and SEM confirmed a uniform coating layer. In conclusion, cetyl alcohol 1% is the optimal formulation, providing superior physical characteristics, the lowest water absorption, and meeting microbiological safety standards.
