The physico-chemical parameters of detergents with the anionic nature, namely sodium myreth sulfate and sodium lauryl sarcosinate used most often when developing domestic foaming products for personal hygiene, at the cosmetic enterprises of Ukraine have been studied and analyzed. The indicators of the foaming ability (foam number, foam stability) of the test samples at different pH values, namely at the neutral pH (5.5-6.0) and at the acid рН (3.5-4.0), have been determined and studied. The study of the foam structure at the pH intervals under research has been also conducted using the method of microphotography. According to the results of the study, the conclusion has been made that different pH values do not affect the foaming ability; however, they affect the foam structure.
Contact lenses are the most convenient and common means of vision correction worldwide. Soft contact lenses in the world are used by a vast majority of contact vision correction enthusiasts (about 90 % of patients) because the lenses are easy-to-use at the very first application and require almost no adaptation, they have high flexibility, small thickness, and as a result the users feel they have a high comfort level immediately after wearing and also the soft lenses are suitable for correction of all major refractive errors of the eye. The analysis of the range and basic commodity characteristics of soft contact lenses, which are present in the pharmaceutical market of Ukraine has been performed. On the basis of Ukrainian market analysis it has been found that dominant positions of soft contact lenses market have: South Korea, Indonesia, joint v entures of EU countries (UK, Italy, Spain), the US and Singapore, and Australia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
