FIELD: medicine, pharmaceutics.

SUBSTANCE: invention relates to field of cosmetology and therapeutic and preventive medicine and represents method for obtaining hygienic preparation with anti-inflammatory and antiseptic action for foot skin care, which includes preparation of mixture of components in form of powder, with zinc oxide, boric acid, salicylic acid being used as components, characterised by the fact that chitosan and acetic acid are additionally used; first zinc oxide, boric acid and salicylic acid are mixed and dispersed in water for 30-60 minutes, after that, said components are subjected to mechanical activation in rotary-pulse apparatus for 4-10 s at gradient of shift rate (10-20)⋅10⁴ s^-1, and then, 2-8 parts of 1% chitosan solution with molecular weight 100-250 kDa and degree of deacetylation not less than 80% in 1% acetic acid are introduced into 100 volume parts of processed dispersion, and re-processing is realised in rotary-pulse apparatus for 5-10 s at the same intensity.

EFFECT: invention ensures high degree of dispersion of hygienic preparation, as well as extension of sphere of preparation applicability due to enabling it to soak fibrous material and remain on them without additional fixing preparations, which provides convenience of application As well as even and prolonged transfer of active substances in contact with skin.
