Петровская в докторанты

Ludmila Petrovskaya is working on a doctoral thesis on the topic: “Development of сomposition and technology of foam cleaning gel with complex antimicrobial activity”, the specialty 15.00.01 – “Technology of drugs pharmacy organizations and judicial pharmacy” scientific adviser – Doctor of Pharmacy, professor. I. Baranova. The aim of the research is to develop modern foam cleaning bases for further development foam cleaning products (for children, for intimate hygiene). Currently known that the most promising anion activ surfactants are oxyethylated with 2-3 moles sodium and magnesium alkyl ether sulphates or disodium salt of lauryl sulfo succinates. Also,it is rational to use and mix lauryl sulfo succinates and decyl glucosides. The latter are the least irritating to mucous membranes. Abroad, when developing soft foam cleaning products are used a mixture of three different classes of surfactants – lauryl ether sulfate, coco amido propyl betaine (amphoteric surfactant) and alkyl polyglycoside (nonionic surfactant). This mixture has optimal dermatological properties. Equally important is the choice of auxiliary substances that affect the developed product quality. Primarily this are the thickening agents and substances that affect the foaming process. It is planned to conduct a comprehensive and systematic research on study gel carriers’ properties with different complexes of modern surfactants (anionic, nonionic, amphoteric). With the use of pharmacotechnological, structural, mechanical, physical, chemical and other scientific research methods to prove the creating principles of foam cleaning products which are meant for skin cleansing.
