摘要：
FIELD: hygiene.SUBSTANCE: group of inventions relates to methods for preparing personal care compositions, such as dentifrices. Methods include the steps of a) forming in a mixing tank, a premix having a lower viscosity than a packaged personal care composition, wherein the viscosity of the premix in the mixing tank is in the range from 0.01 to 10 PA⋅s at sampling rate of 10 s-1； b) transferring the premix from the mixing tank to a high-energy dispersing device suitable for transferring energy density from 0.5 to 11 kW / kg / s； c) introducing a rheology modifier into the premix； d) deaerating the premix and e) packaging the premix to obtain a personal care composition. In one embodiment of the method for preparing a personal care composition, the premix is deaerated using an integrated deaeration device； wherein the integrated deaeration device is located in the immediate vicinity of the high-energy dispersing device, and the pressure difference between the high-energy dispersing device and the integrated deaeration device is less than the pressure head of the high-energy dispersing device. Introduction of rheology modifiers at a late stage in the process of obtaining a personal care composition makes it possible to minimise losses from flushing the mixing tank due to the thickened premix and, accordingly, to reduce downtime between batches.EFFECT: low rheology of the premix provides high throughput in the mixing tank and also increases the efficiency and rate of deaeration.19 cl, 3 tbl, 1 ex, 4 dwgГруппа изобретений относится к способам получения композиций для личной гигиены, таких как средства для ухода за зубами. Способы включают стадии, на которых a) получают в смесительном резервуаре премикс, имеющий более низкую вязкость, чем упакованная композиция для личной гигиены, при этом вязкость премикса в смесительном резервуаре находится в диапазоне от 0,01 до 10 Па⋅с при отборе проб при 10 с-1； b) переносят премикс из смесительного резервуара в высокоэнергетическое
