Abstrak: Industri kosmetik saat ini banyak menggunakan bahan kimia dari minyak bumi yang terbatas dan tidak ramah lingkungan. Bio propilen glikol, yang berasal dari bahan nabati, dapat menjadi alternatif sebagai humektan dan bahan pelarut. PT Ratu Bio Indonesia perlu mengembangkan produk kosmetik untuk memenuhi permintaan konsumen, termasuk handbody lotion yang membantu merawat kesehatan dan kelembaban kulit. Pengembangan formulasi handbody lotion dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan tiga taraf propilen glikol (2%, 5%, dan 8%). Formulasi terbaik ditentukan melalui Composite Performance Index (CPI) dan Analytical Hierarchy Process (AHP). Hasil ANOVA menunjukkan propilen glikol berpengaruh signifikan terhadap pH, viskositas, bobot jenis, dan kelembaban lotion. Formulasi terbaik dengan konsentrasi 5% bio propilen glikol menunjukkan stabilitas fisik yang baik dengan nilai pH 6,71, viskositas 17500 cPs, kelembaban 54%, dan ukuran droplet 4,7 µm, The cosmetics industry currently uses many chemicals from petroleum which are limited and not environmentally friendly. Bio propylene glycol, which comes from vegetable ingredients, can be an alternative as a humectant and solvent. PT Ratu Bio Indonesia needs to develop cosmetic products to meet consumer demand, including handbody lotion which helps maintain skin health and moisture. Lotion formulation development was carried out using a Completely Randomized Design (CRD) with three levels of propylene glycol (2%, 5% and 8%). The best formulation is determined through the Composite Performance Index (CPI) and Analytical Hierarchy Process (AHP). ANOVA results showed that propylene glycol had a significant effect on pH, viscosity, specific gravity, SPF, and lotion moisture. The best formulation with a concentration of 5% propylene glycol showed good physical stability with a pH value of 6.71, viscosity of 17500 cPs, humidity of 54%, and droplet size of 4,7 µm.
