RosSalacca: A Natural-based Ingredients Soap from the Extract of Salacca Fruit Seeds and Skin

Salak seeds contain high phenolics. Phenolic has antioxidant properties and works to prevent free radicals (Alaras, 2010). In fact, salak fruit skin also contains phytochemicals that have anti-aging potential (Girsang et al., 2019). Salak fruit seeds contain nutrients such as β-Sitosteryl-3β- glucopyranoside-6'-O-fatty and acid Esters while the seeds contain Gallic acid Peel, Caffeic acid, Ferulic acid, Chlorogenic acid, Quercetin and Rosmarinic acid (Salleh et al., 2018). With that, salak fruit becomes a good source of antioxidants with bioactive content. An extensive exposure to free radicals from air pollutants and sun UV rays often leads to skin damage and other health problems. Therefore, green chemist and cosmetic expertise are expected to develop and innovate products that have great potential to overcome these problems. Seeds and skin of salacca fruit have excellent antioxidant properties which can prevent deterioration of skin cells. Recognizing their high nutritional and medicinal value, we aim to synthesize an effective and eco-friendly soap derived from the extract of rose and salacca fruit’s seeds and skin and. The extraction process was conducted via solid-liquid extraction technique in which a mixture of ethyl acetate and hexane (1:1) was used as extractable solvent. Then, the extracted oil was mixed with 0.1 M NaOH for saponification process. The soap produced has a smooth texture, soft foams and liberate soothing fragrant smell. After that, the presence of antioxidant compound of the soap was validated from Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) spectrum. This innovation not only opens the idea to the reduction of food and agricultural waste, but also to the utilization of highly nutritious ingredients in producing a product that is beneficial for skin health.
