This study presents an analytical and biological evaluation of selected vegetable oils and their unsaponifiable compounds,which are of crucial importance for the cosmetic and pharmaceutical industries, with the aim of ensuring their targeted use in dermalproducts. Methods: Vegetable oils were selected based on their dominant fatty acid composition: pomegranate seed oil (punicicacid), linseed oil (α-linolenic acid), coconut oil (lauric acid), olive oil (oleic acid), poppy seed oil (linoleic acid), linden seed oil (linoleicacid), and marigold seed oil (α-calendic acid). Pharmacopoeial chemical values, fatty acid profiles, and unsaponifiable compoundswere analysed. Antioxidant activity was measured using DPPH assay. Results: Chemical values indicated good oxidative status andminimal hydrolysis. Fatty acid analysis revealed expected compositions, with rare linden and marigold seed oils exhibiting distinctivefatty acid composition, featuring sterculic and α-calendic acids. Marigold seed oil showed the richest profile of unsaponifiable com-pounds. Antioxidant activity was highest in olive oil and lowest in coconut oil. No significant correlation was found between the fattyacid composition, unsaponifiable matter, and antioxidant activity suggesting the synergistic or antagonistic interactions of oilcomponents. Conclusion: The study highlights the complex interactions among oil components that influence antioxidant activity.These findings deepen the understanding of the complex mechanisms determining the antioxidant properties of vegetable oils,crucial for informed decisions in dermal product formulation as demand for natural, effective cosmetic and pharmaceutical ingre-dients rises.
