Fabric conditioning compositions
View Patent ↗A fabric softening composition comprises a cationic fabric softening compound comprising 2 or more long hydrocarbyl chains, an oil comprising from 8 to 40 carbon atoms, a nonionic stabiliser comprising a nonionic alkoxylate having an average alkoxylation number of from 10 to 40 wherein the composition is in the form of a macroemulsion. A method for softening fabrics comprises adding the fabric softening composition to a laundry operation.
1. An aqueous fabric softening composition comprising:
(i) about 11% to about 21% by weight based on the weight of said composition of a cationic fabric softening agent comprising at least two long hydrocarbyl chains;
(ii) about 10% to about 35% by weight based on the weight of said composition of one or more hydrocarbon oils comprising from 11 to 30 carbon atoms; and
(iii) one or more nonionic stabilisers comprising 0.5% to 2.7% by weight based on the weight of said composition of an alkoxylated alcohol having an average alkoxylation number of from 11 to 40; and
(iv) a single long hydrocarbyl chain cationic surfactant;
wherein the weight ratio of said oil to said nonionic stabilizer is about 60:1 to about 1:10; and
wherein the composition is in the form of a macro-emulsion.
2. An aqueous fabric softening composition according to claim 1 in which the fabric softening compound comprises a quaternary ammonium group and at least one ester link.
3. A fabric softening composition according claim 1 where the single long chain hydrocarbyl cationic surfactant is present at a level from 0.01 to 5% by weight, based on the total weight of the composition.
4. A fabric softening composition according to claim 1 further comprising perfume.
5. A process for producing an aqueous fabric softening composition comprising mixing one or more cationic fabric softening agents comprising two or more long hydrocarbyl chains with about 10% to about 35% by weight based on the weight of said composition of one or more hydrocarbon oils comprising from 11 to 30 carbon atoms and with one or more nonionic stabilisers comprising 0.5 to 2.7 by weight based on the weight of said composition of an alkoxylated alcohol having an average alkoxylation number of from 11 to 40 so as to form a fabric softening composition in the form of a macro-emulsion comprising about 11% to about 21% by weight of the cationic fabric softening agent based on the weight of the composition.
