Rheology control agent

A method of controlling the rheology of a liquid composition, the method comprising:

• mixing a liquid composition with a rheology control composition,
• the rheology control composition comprising a mixture of compounds according to formula (I)
• wherein IC1 and IC2 independently of one another and of each occurrence represent a hydrocarbyl group,
• AM independently of each occurrence represents a hydrocarbyl group,
• m is the average number of repeating units from 0 to 20,
• RP1 and RP2 independently of one another and of each occurrence represent an organic group selected from RP3, RP4, RP5,
• wherein RP3 represents a hydrocarbyl group,
• RP4 represents an organic group according to formula (II)
• RP41-(AO)n- (II)
• wherein RP41 represents a hydrocarbyl group having 1 to 24 carbon atoms,
• AO represents an alkylene oxide repeating unit and
• n is the average number of repeating units from 6 to 30,
• RP5 represents an organic group according to formula (III)
• RP51-(AO)p- (III)
• wherein RP51 represents a hydrocarbyl group having 1 to 24 carbon atoms,
• AO represents an alkylene oxide repeating unit and
• p is the average number of repeating units from 1 to 5,
• wherein the mixture comprises compounds of formula (I) wherein
• (A) RP1 is RP3 and RP2 is RP4,
• (B) RP1 is RP4 and RP2 is RP5,
• (C) RP1 is RP3 and RP2 is RP5.
