description	FIELD: chemistry. ^ SUBSTANCE: invention relates to stabilisation of dispersed aqueous systems which are used in pharmaceutics and cosmetology. Disclosed is a method of stabilising an aqueous dispersion with microencapsulated hydrophobisated nanosilica, involving addition of polyvinyl alcohol with concentration of not less than 5 wt % as a stabiliser into the aqueous dispersion. ^ EFFECT: low power consumption and costs when producing a stable aqueous dispersion which is resistant to freezing and thawing. ^ 1 cl, 1 tbl Изобретение относится к области стабилизации дисперсных водных систем, которые применяются в фармацевтике и косметологии. Предложен способ стабилизации водной дисперсии, микрокапсулированной гидрофобизированным нанокремнеземом, включающий введение в нее в качестве стабилизатора поливинилового спирта с концентрацией не менее 5 вес.%. Технический результат - снижение энергетических и экономических затрат при получении стабильной водной дисперсии, устойчивой к замерзанию и оттаиванию. 1 табл.
