Vegetable Oils Selection Guide: New insights on the sensorial scientific studies

Synopsis

Vegetable oils applied directly to skin, or incorporated to cosmetic formulations provide a different sensory effect, depending on their respective texture. Texture and, subsequently, physical behaviour of a vegetable oil on skin is determined by its fatty acid composition and physico-chemical properties. Characterizing the sensory behaviour of vegetable oils applied on skin through objective measurements is key to obtain reliable results to be used in building evidence-based cosmetic claims. To this aim, we studied a collection of ten cosmetic vegetable oils through an in-vivo sensory study conducted on a panel of human volunteers. Studying several attributes upon application on skin allowed us to generate a sensory profile for the natural oils investigated. Comparison among them could assist in formulation design and ingredient selection based on certain sensory properties or desired applications.
