Green Synthesis of Cosmetic Soaps Obtained from Laurel Nobilis

Abstract

In this study, Laurel nobilis oil was obtained from Laurel nobilis fruits. Qualitative analysis of Laurel fixed oil was performed by GC-MS. Additionally, saponification value (SV), acid value (AV), free fatty acid value (% FFA) and peroxide value (PV) values of bay Laurel oil were determined as 140.0 mg KOH/g, 26.5 mg KOH/g, 13.25 mg KOH/g, and 10.28 meq O2/kg, respectively. Activated carbon was obtained as a result of carbonization of the Laurel fruit seeds, which were waste as a result of oil extraction, at 500 oC. Activated carbon was characterized by FT-IR, BET, SEM and TGA. Soap is made of different fatty acid salts, either sodium or potassium. The obtained Laurel fruit oil and activated carbon were used in the preparation of solid soaps with peeling effect by the cold process method. pH, foam test, total alkaline test, and total fatty matter determination (TFM) of the prepared soaps were determined. Thus, the synthesis of activated carbon with peeling effect, which has good cleaning and foaming properties, was carried out.
