COMPOSITIONS WITH CLOTH SOFTENER, WHICH ARE STABLE UNDER CONDITIONS OF FREEZING-UNFREEZING Russian patent published in 2010 - IPC C11D1/62 C11D3/00 C11D3/22 C11D3/20 C11D1/835 

FIELD: textile industry.

SUBSTANCE: lightproof composition added in process of cloth rinsing has viscosity of less than 500 mPas after at least one cycle of freezing-unfreezing and contains from approximately 5 to approximately 30 wt % of active component, more than 5 wt % of polyol, which represents polyatomic alcohol that is not ethylene glycol, propylene glycol, diethylene glycol or dipropylene glycol and 0.1-10 wt % of additional softener selected from hydrophobised ether of saccharose, cationic starch, aminofunctional silicon or their mixtures. Active component represents compound or mixture of compounds, having the following formula: {R_4-m-N⁺-[(CH₂)_n-Y-R']_m}X^-, (a), where each R is hydrogen, short chain C₁-C₆, poly(C_2-3 alkoxy), benzyl, or their mixtures; m = 2 or 3; n = 1-4; Y = -O-(O)C- or -C(O)O; sum of carbon atoms in each R¹=C¹¹-C²¹, for each R¹, which represents hydrocarbyl or substituted hydrocarbyl group; and X-anion compatible with softener; or {R_4-m-N⁺-[(CH₂)_n-Y-R']_m}X^-, (b), where each R is hydrogen, short chain C₁-C₆, poly (C_2-3alkoxy), benzyl, or their mixtures; m = 2 or 3; n =1-4; Y=CH₂, -NR-C(O)-, or -C(O)-NR- and each Y is same or different; sum of carbon atoms in each R¹ minus (n+1), when Y is CH₂, is equal to C₁₂-C₂₂, for each R¹, which represents hydrocarbyl or substituted hydrocarbyl group; and X- any anion compatible with softener; or (c), where each R, R¹, and A^- have values given above; each R² -C₁-C₆ alkylene group; and G - atom of oxygen or -NR-.

EFFECT: softener has good dispersive ability and spreading property when stored at low or high temperature.
