Abstract:
A fabric softener concentrate composition in the form of a water-in-oil emulsion containing at least about 2% by weight water and comprising a mixture of at least one non-ionic surfactant and at least one water insoluble oil containing a polar proton sharing group and having a melting point below about 30.degree. C., said non-ionic surfactant being the condensation product of an aliphatic alcohol having from about 6 to 26 carbon atoms with ethylene oxide, said oil being selected from the group consisting of saturated aliphatic alcohols or acids containing from about 6 to 12 carbon atoms and unsaturated liquid fatty C.sub.16 to C.sub.18 acids or alcohols, said fabric softener concentrate containing from about 1 to about 25% by weight of a cationic or nonionic fabric softener compound, said concentrate characterized by a viscosity of at least about 10 cps and further characterized that, upon dilution with at least about one volume of water per volume of concentrate, the concentrate is at least partially converted into a liquid crystal phase dispersion providing a diluted concentrate having a viscosity of at least about 50 cps.
