Abstract
Abstract Shelf-stable/biodegradable fabric softening compositions are provided comprising mixtures of a quarternary ammonium salt containing at least one ester linkage, a linear alkoxylated alcohol, and a liquid carrier. These biodegradable compositions have improved product stability and dispersability, as well as excellent fabric softening characteristics.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
160 words
A liquid fabric softening and antistatic composition comprising a quaternary ester-amine softening compound and a liquid carrier, which composition is characterized in that the composition contains: (a) from 1% to 25%, preferably 11% to 25%, by weight of a quaternized ester-amine softening compound having the formula and mixtures thereof; wherein each R substituent is a C I -C G alkyl or hydroxyalkyl group, or mixtures thereof; R I is or a C 13 -C 19 hydrocarbyl group; R 2 is a C 13 -C 21 , hydrocarbyl group; and X- is a softener compatible anion; (b) from 0.1% to 10% of a linear alkoxylated alcohol selected from the group consisting of the condensation products of C 8 -C 18 , preferably C 10 -C 15 , linear fatty alcohols, with from 1 to 10 moles, preferably from 2 to 5 moles, of ethylene oxide or propylene oxide, and mixtures thereof; and (c) from 60% to 98% of the liquid carrier.
Claim 2
Dependent Claim
160 words
A liquid fabric softening and antistatic composition comprising a quaternary ester-amine softening compound and a liquid carrier, which composition is characterized in that the composition contains: (a) from 1% to 25%, preferably 11% to 25%, by weight of a quaternized ester-amine softening compound having the formula and mixtures thereof; wherein each R substituent is a C I -C G alkyl or hydroxyalkyl group, or mixtures thereof; R I is or a C 13 -C 19 hydrocarbyl group; R 2 is a C 13 -C 21 , hydrocarbyl group; and X- is a softener compatible anion; (b) from 0.1% to 10% of a linear alkoxylated alcohol selected from the group consisting of the condensation products of C 8 -C 18 , preferably C 10 -C 15 , linear fatty alcohols, with from 1 to 10 moles, preferably from 2 to 5 moles, of ethylene oxide or propylene oxide, and mixtures thereof; and (c) from 60% to 98% of the liquid carrier.
