Sunflower oil is derived from the seeds of the sunflower plant, Helianthus annuus, a widely cultivated crop across the globe [1]. The oil is valued for its light texture and health benefits, due to its rich composition of unsaturated fatty acids and vitamin E [2]. It is extracted through pressing or solvent extraction methods, which are then refined to meet cosmetic-grade standards, and resulting in a clear, pale yellow liquid [3].

The production process of sunflower oil begins with harvesting sunflower seeds; then the seeds are cleaned and dehulled [4]. After dehulling, the seeds undergo pressing, either through mechanical expellers or cold-pressing methods, to extract the crude oil [5]. The crude oil is then refined through processes, such as degumming, neutralization, bleaching, and deodorization, to remove impurities, color, and odor, and ensuring the oil meets the requirements for cosmetic applications [6]. Quality control measures are implemented throughout the process to maintain consistency and purity [7].

Sunflower oil is primarily used in cosmetics for its emollient and skin-conditioning properties; it helps to moisturize and soften the skin without leaving a heavy or greasy feel [8]. The high content of linoleic acid helps to maintain the skin barrier function and reduce transepidermal water loss [9]. Vitamin E in sunflower oil acts as an antioxidant, protecting the skin from free radical damage and environmental stressors [10].

Sunflower oil is a versatile ingredient, incorporated into formulations, like creams, lotions, serums, and hair care products [11]. It can be used in massage oils due to its light texture and moisturizing effect [12]. Sunflower oil is also suitable for sensitive skin formulations, given its mild and non-irritating nature [13].

Sunflower oil is typically stored in tightly sealed containers, away from direct sunlight and heat, to prevent oxidation and maintain its quality [14]. During transportation, containers should be handled carefully to avoid physical damage; temperature control may be necessary, particularly in extreme climates, to prevent changes in viscosity or degradation of the oil [15]. Proper labeling and documentation are essential for compliance with regulatory requirements and to ensure safe handling throughout the supply chain [16].
