“…The definitions were adopted from ASTM D1490 Standard Guide for sensory descriptive analysis of creams and lotions and the authors used them in the paper as a proposition of a tool for testing the quality of the PCs for occupational skin diseases. [6] All assessors were also asked to evaluate the attribute intensity on 5-point scale, where 1 was the lowest score and 5 was the highest. The score point of the assessed PC sample was calculated as the average from all assessors.…”

“…The sensations felt on the skin during product application can be also correlated with rheological parameters. [6,[54][55][56] In the case of ointments (anhydrous systems with high content of fatty substances), it is important that the preparation showed plasticity, adequate fluidity, and spreadability at human body temperature. These properties can be determined with the analysis of spreadability by parallel-plate method, consistency (cone penetration depth), or by determining the apparent viscosity at specified shear rates.…”

“…It can also be a locally-applied medical device. [5,6] One of the types of PCs available on the market are the hydrophobic BCs for the works in wet environment. [7] Such works include activities where the workers have their hands in a wet environment regularly for more than 2 h/day.…”

“…[10] If the product does not adhere correctly to the skin, its effectiveness is reduced. [6,11] Therefore, the human factor is important here. The person exposed to irritant and harmful factors must want to and know how to apply the preparation on the skin of hands, face, neck, and neckline to maximize its effectiveness.…”

“…In order to protect the skin appropriately, the user cannot spread the PC for too long or wait for extended time before starting the work. [6] It can be then clearly concluded that users' acceptance of the product is closely related with their view of how it can be spread on the skin. [12] Spreadability of a cosmetic product can be defined as its capability to cover an area of skin more or less quickly on the skin.…”

The aim of the study is 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. The research hypothesis assumes 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 is determined using instrumental analysis and sensory analysis. Also, TEWL tests are used to evaluate their occlusal properties. For protective preparations based on them, the distribution capacity is tested by in vitro methods as well as in vivo tests and sensory analyses are performed. The effectiveness of the tested preparations is measured by tests concerning absorbability, occlusion capacity and washability. The results are analyzed and compared, and a correlation matrix is 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. Practical Applications: For hydrophobic preparations of ointment type, there is a possibility to implement such instrumental techniques as: determination of preparation consistency by means of a cone, ability to distribute by means of parallel plates, but also determination of preparation viscosity by rheological methods. Viscosity, spreading ability, and oil occlusion ability are the most important parameters that should be taken into account when we design hydrophobic skin protection preparations intended for the works in the wet environment.
