Studying the ways of stabilization of water extraction from camomile and calendula flowers, yarrow grass

Water extraction from herbs are the part of syrups, lotions, shampoos, creams, agents for baths, impreg-nations for wet napkins, etc. The purpose of the given work is studying the ways of microbiological and chemical stabilization of water extraction from camomile and calendula flowers, yarrow grass. As a re-sult of the lead researches it is established, that by optimum conditions of reception of extraction, stable within two years, are: extraction the raw material by cleaned boiling water, microbiological stabilization by addition nipagin in concentration of 0,15%, chemical stabilization by addition of sodium metabisul-phite (0,5%) and trilonum (0,5%).
