The aim of the study was to demonstrate the effect of the addition of vegetable oils rich in EFA on the effectiveness of hydrophobic skin protection preparations intended for work in the wet environment. Our research hypothesis assumed that the increase in the concentration of vegetable oils in the formula of protective preparations improves their spreadability on the skin, thus translating into acceptance of the preparations by users, improving their quality of life, strengthening the barrier functions of the skin without reducing the effectiveness of the protective action. The distribution capacity of pure vegetable oils was determined using instrumental analysis and sensory analysis, also TEWL tests were used to evaluate their occlusal properties. For protective preparations based on them, the distribution capacity was tested by in vitro methods as well as in vivo tests and sensory analysis were performed. The effectiveness of the tested preparations was measured by tests concerning absorbability, occlusion capacity and washability in aqueous medium. The results were analyzed and compared, and a correlation matrix was developed to establish the relationship between sensory and instrumental measurements. The effectiveness of the preparations depends on the type of oil (its spreadability and viscosity) and the amount in the formulation.
