Natural muds have therapeutic effect on the human body that makes them to be a promising raw material for the cosmetics production. Methods. The research work covers physico-chemical characteristics, toxicological and microbiological properties of lacustrine-spring mud from the depths of the lake “Utinoe” in Kamchatka Territory. The irritant action of the mud has been studied in the experiment on guinea pigs. Results. Physico-chemical, mineral, microbiological and toxicological properties of the mud samples meet the standards for perfumes and cosmetics. No signs of irritation of the skin as well as mucous membranes caused by mud applications have been registered. Conclusions. Considering the data obtained, for the cosmetics production it is necessary to prepare the mud from the depths of the lake “Utinoe” by refining it through a sieve No. 05 and diluting to the right consistency. The authors developed the following types of cosmetic forms: bottles with dried mud and mineral water, tubes with liquid cosmetic mud, cosmetic mud masks, sprays and bottles with mineral water.
