Abstract

The Sun Protection Factor (SPF) indicates the level of protection that a sunscreen formulation provides against ultraviolet (UV) radiation. The heavy fraction patchouli oil obtained via molecular distillation contains 90.48% patchouli alcohol, which exhibits antioxidant activity. This study aimed to determine the SPF value of the heavy fraction patchouli oil and to evaluate the characteristics and SPF values of emulgel-based chemical sunscreens. Patchouli oil demonstrated an in vitro SPF of 37.63, classified as ultra-protection. Sunscreen formulations were prepared using the beaker method, with patchouli oil incorporated at varying concentrations, including 0% (control), 0.25% (F1), 0.5% (F2), and 1% (F3). The formulations were evaluated for physicochemical characteristics, stability, and skin safety. They exhibited an opaque white to ivory color, with a pH range of 5.2 to 6.4, viscosity between 2011 and 2924 cPs, spread ability of 4 to 6 cm, adhesion time of 5.38 to 8.28 seconds, and an oil-in-water (O/W) emulsion type. The SPF values of the sunscreen formulations ranged from 8.85 to 29.02, with F3 achieving an SPF of 29.02 and classified as ultra-protection. All formulations met the established quality standards, remained stable during storage, and caused no irritation in human volunteers. These findings indicate that the heavy fraction of patchouli oil has great potential as an active ingredient for chemical sunscreen products.

Abstract

Patchouli oil and citronella oil are Aceh’s leading commodities that produce essential oils with various benefits, including natural antibacterial properties. However, their utilization in household products remains limited, while most communities still rely on chemically based floor cleaners at relatively high prices. In response to this potential, a community service program was conducted in Pango Deah Village by empowering beneficiaries of the Family Hope Program (PKH) to innovate in producing antibacterial floor cleaning soap based on patchouli and citronella oils. The activities included socialization on household hygiene, technical training on soap production, hands-on practice through a learning-by-doing approach, and evaluation using pre-test and post-test assessments. The evaluation results showed an increase in the average score from 78.50% to 99.00% after the training, indicating a significant improvement in participants’ understanding and practical skills. All participants (100%) expressed high satisfaction with the content, methods, and overall benefits of the program. The resulting floor cleaning soap exhibited a distinctive aroma of patchouli and citronella, as well as good product stability, making it a promising environmentally friendly household product with market potential. Participants’ enthusiasm was demonstrated by their intention to further develop the product as a home-based business. This program is expected to enhance community skills, promote economic independence, and encourage the sustainable utilization of local resources.
