Fabric softening composition |
(57) A fabric softening composition comprising at least 1% by weight of a water insoluble
cationic fabric softening agent and a nonionic stabilising agent wherein the water
insoluble cationic fabric softening agent is a quaternary ammonium material which
comprises a compound having two C₁₂₋₂₈ alkyl or alkenyl groups connected to the quaternary
nitrogen atom via an ester link wherein the nonionic stabilising agent is selected
from predominantly linear C₈ to C₂₂ alcohols alkoxylated with 10 or more moles of
alkylene oxide and the nonionic stabilising agent has a clear phase at a 1% concentration
in water somewhere in the range of 0°C and 45°C and a Krafft point less than 30°C.
