Creams are designed as topical compositions for care or therapeutic purposes. Apart from oils and water they contain a variety of biologically active and fragrant components. All components are also responsible for physicochemical properties of the preparations. The latter jointly with sensory properties have an essential impact to the quality, shelf-life and mode of application of the creams. Aim. It is likely that exposure of either creams or skin covered with cream to magnetic field (MF) can improve care effects and facilitate application of the creams.. Materials and methods. Nivea universal cream for every skin, Soraya oil based antiwrinkle cream and Ziaja natural olive based cream for normal and dry skin were subjected to magnetic field at room temperature for 1, 15 and 30 min and the effects of those operations were examined rheologically by running mechanical spectra of exposed and unexposed samples. Also spreadibility of the exposed and original creams was qualitatively compared. Results. Elasticity and plasticity of Nivea and Soraya creams are stable to the influence of magnetic field whereas these parameters for Ziaja creams decrease when placed in MF. After initial 1 min action of MF which produces the most noticeable decrease in elasticity and plasticity, and further up to 30 min exposure to MF resulted in an irregular in time decrease in the elasticity and plasticity. Spreadibility of Nivea cream after exposure to MF was better and the adhesiveness and absorption were closely identical. MF distinctly improved spreadibility and absorption of Soraya cream and the adhesiveness is reduced but not removed. Absorption of Ziaja cream is insensitive to MF, and its adhesiveness is essentially lowered by MF and spreadibility is slightly improved. Conclusions. Magnetic field influences rheology of some cosmetic creams and improves their spreadibility, absorption and adhesiveness.
