The study of possibility of magnetic microparticle deposit in skin at superficial application

The depth of penetration and localization of magnetic microparticles in skin under action of magnetostatic field was studied experimentally. In the study magnetic powder made from intermetallic composition SmCo$_5$ consisting of 37$\%$ of samarium and 63$\%$ of cobalt was used. Sizes of the particles varied in the range 3-5 $\mu$m. As a carrier propylene glycol was used. The experiments were carried out with human skin samples in vitro. It was shown that the magnetic suspension on the basis of magnetic microparticles SmCo$_5$ applied on the skin surface, accumulated in skin appendages (sweat and sebaceous glands, hair follicles) in the depth up to 1 mm.
