This research examines the quality and stability of three types of vegetable oils—Argan, Almond, and Jojoba—through a comprehensive series of physicochemical analyses. The evaluations yielded essential insights regarding the stability, purity, and authenticity of argan, jojoba, and almond oils, with results compared against reference standards and technical specifications to verify adherence to the quality criteria required for cosmetic products. The results indicated that all three oils complied with the data outlined in their respective technical sheets, meeting the necessary quality control standards. Following the Romanian Pharmacopoeia, polyphenols were detected through a chemical reaction, revealing that argan oil contained the highest concentration of phenolic compounds, as evidenced by a vibrant blue-green hue, while jojoba and almond oils exhibited a less pronounced coloration. The antioxidant capacities of the oils were assessed utilizing the spectrophotometric FRAP method. Argan oil displayed the highest antioxidant activity, achieving a value of 11.12 M /L in the FRAP test, indicating a superior ability to neutralize free radicals and reduce ferric ions. This research underscores the potential of argan oil as a potent antioxidant, next to its quality as a cosmetic ingredient.
