The aim of the research was to substantiate the technological parameters of cream production with the sapropel extract and work out the technological scheme for its production. In this study, extract of sapropel from the Prybych deposit, emulsion base, containing corn oil, emulsifier No.1, cetylstearyl alcohol, nisin, euxyl K 100 and purified water were employed. To carry out the research, a set of methods to analyse colloidal and thermal stability was used. Rheological properties of the samples were determined. The method of microscopic analysis was carried out to analyse the stability of the emulsion system. It was proved experimentally that, when producing the cream, it is appropriate to use the phase inversion method, and the emulsification needs to be carried out at 5000 r/m for 20 min. Size and shape of the sample drops, obtained at 5000 r/m, were monodisperse and more uniform, most of which range from 2 to 3 microns that indicates the system stability. The following parameters of technological process were determined: mixing temperature conditions, speed of homogenisation and mixing time.
BACKGROUND: The use of sapropel in balneology, cosmetology, and also products of its processing as an active pharmaceutical ingredient for the creation of medicines requires a mandatory assessment of the degree of toxicity. The toxicological and biological characteristics of sapropel (silt deposits) from the Prybych lake of the Shatsky Lakes group of the Volyn region of Ukraine were based on the results of studies of the functional state of the central nervous system (CNS), autonomic reactions, and structural and functional changes in the internal organs (heart, stomach, liver, and kidneys) of white rats with external use of sapropel. An analysis of acute toxicity, locally irritating, and sensitizing action of sapropaste (a product from sapropel) was also carried out. AIM: This study aimed to conduct of toxicological and biological assessment of the effect of sapropel from the Prybych Lake during cutaneous application in rats to justify the prospects for its further use in balneology, medicine, and for the development of new drugs. METHODS: This study was an in vivo experimental study. As many as, 50 rats were grouped into three treatment groups and two groups of controls. RESULTS: In essence, indicators of locomotor activity and orientation-research behavior of animals do not change (p > 0.5). A stimulating effect on the emotional state of animals, characterized by an increase of grooming duration (p < 0.001), was found. Animals feel calm. A moderate stimulating effect on vegetative reactions manifests itself in a slight increase in urination acts (p < 0.05). Microscopic studies confirmed the absence of the damaging effect of sapropels on the structural and functional state of the organs studied, and signs of increased secretory activity of the gastric mucosa were also noted. CONCLUSIONS: It was experimentally established that the sapropel of the Prybych Lake does not have a harmful or toxic effect on the CNSs functional state and the liver, kidneys, heart, and stomach of rats. Sapropaste does not exhibit sensitizing and locally irritating properties and belongs to the class of practically non-toxic substances (toxicity Class V).
Вивчення ефективності антимікробних консервантів у гелях з екстрактом сапропелю Актуальність. Обов'язковою умовою забезпечення якості лікарських препаратів є їх стабільність у процесі зберігання, в тому числі і мікробіологічна чистота, яка в переважній більшості препаратів для нашкірного застосування забезпечується введенням консервантів. Мета роботи. Обґрунтування вибору консерванту при розробці стабiльного гелю з екстрактом сапропелю. Матеріали та методи. В якості об'єкту дослідження використовували гелі з екстрактом сапропелю та низкою консервантів. При дослідженнях використовували методику оцінки ефективності антимікробних консервантів згідно з ДФУ 2.0. Результати та їх обговорення. Мікробіологічними дослідженнями підтверджена різна інтенсивність консервуючої дії обраних в середньо ефективній концентрації консервантів: ніпагіну, натрію бензоату та калію сорбату. Встановлено, що розроблений гель мiсцевої дiї з екстрактом сапропелю потребує додаткового введення консерванту. Висновки. На пiдставi проведених мiкробiологiчних дослiджень в якостi консерванта до складу гелю з екстрактом сапропелю обґрунтоване введення калію сорбату в концентрацiї 0,2 %.
