6. Conclusion and Outlook

Oil foams are emerging as a key component for developing innovative, multifaceted formulations rich in oils. Their potential lies in their ability to transform formulations based on vegetable oils in particular—whether for food, cosmetics, or pharmaceuticals. They enable the reimagining of formulations by reducing traditional fats and limiting the use of often-controversial chemical additives. They contribute to the creation of healthier, more natural products, in line with growing consumer expectations regarding transparency, naturalness, and clean labeling. Their cross-cutting applications – —from functional foods to sensory cosmetics, including the topical delivery of active ingredients – —make them a prime area of research for water-free formulations. However, despite their many advantages, oil foams still present certain challenges. A deeper understanding of the stabilization mechanisms—which...
