METHOD OF PRODUCING PERSONAL HYGIENE COMPOSITION USING COMPACTED RHEOLOGY MODIFIERS Russian patent published in 2019 - IPC A61K8/04 A61Q11/00 B01J13/00 

FIELD: hygiene.

SUBSTANCE: group of inventions relates to personal hygiene means and methods of producing personal hygiene compositions. Method comprises producing a premix in the mixing tank having a lower viscosity than the packaged personal hygiene composition, wherein the viscosity of the premix is in range of 0.01 Pa · s to 10 Pa · s, as measured by the AR2000 rheometer during sampling at 10 s^-1; compacted powdered mass of rheology modifier into a premix, wherein compacted rheology modifier is at least one selected from a group consisting of xanthan gum, carboxymethyl cellulose, carrageenan, carbomer, hydroxyethyl cellulose, guar gum or thickening silica, wherein the rheology modifier is sealed by a roller compactor, wherein the force used for compaction lies in range of 300 kgf/pg cm of the roll width to 4,000 kgf/pg cm of the roller width; transfer of premix from mixing tank into high-energy dispersing device, suitable for transfer of energy density from 5 kW/kg/s to 25 kW/kg/s; and premix packing to produce personal hygiene composition.

EFFECT: group of inventions provides delayed release of rheology modifiers into a premix in order to slow the process of increasing viscosity of the composition and to realize the main part of the process of preparing the personal hygiene composition at considerably lower viscosities.
