LIQUID TREATMENT COMPOSITION Russian patent published in 2012 - IPC C11D3/40 C11D3/37 C11D17/00 

FIELD: chemistry.

SUBSTANCE: composition contains an inorganic pearlescent agent, 0.99 of the total particle volume of which comprises particle size less than 50 mcm, and an external rheology modifier which ensures thinning of the composition during shear, and a surfactant. The composition contains 0.01-2.0% of the weight of the composition of 100% active inorganic pearlescent agent selected from a group consisting of mica, mica coated with a metal oxide, mica coated with bismuth oxychloride, bismuth oxychloride, glass, glass coated with a metal oxide, and mixtures thereof. The rheology modifier is selected from non-polymeric crystalline hydroxy-functional materials, polymeric rheology modifiers which impart viscosity to the composition under high shear load (20 s^-1 and 21°C) from 1 to 1500 cP, and viscosity at low shear load (0.05 s^-1 and 21°C) higher than 5000 cP.

EFFECT: high stability of the suspension and preventing deposits on treated surfaces.
