TRANSPARENT CONCENTRATED LIQUID COMPOSITIONS FOR FABRIC SOFTENING Russian patent published in 1999 - IPC

FIELD: compositions for fabric softening. SUBSTANCE: proposed transparent microemulsion composition for fabric softening in rinsing cycle includes fabric softener (A) which is surface-active agent based on diester of quaternary ammonium having formula (1) where R is alkylene radical having from 2 to about 4 atoms of carbon, R′ is alkyl or alkenyl group having from 8 to about 22 atoms of carbon, "n" is integer, from 1 to 4 and R″ is lower radical having from 1 to about 4 atoms of carbon and/or fabric softener which is surface-active agent based on diamido-ammonium having formula (2), where "n", R and R′ are determined above; R′ is lower alkyl radical having from 1 to about 4 atoms of carbon or hydrogen and "X" is R″SO-4

, Br or C1, where R″ is lower alkyl radical having from 1 to about 4 atoms of carbon. Composition includes also organic solvent (/Б/), water-insoluble optional oil perfume and optional secondary fabric softener (/Г/) selected group consisting of fatty alcohols, fatty acids, fatty esters, fatty amines and/or amines/amides; above-mentioned microemulsion may change into milk-like microemulsion after diluting with water. EFFECT: improved characteristics of composition. 28 cl, 9 tbl, 32 ex
