A fabric softening product which is a composition or an article for application to fibrous materials so that a fabric softening component thereof is deposited on the fibrous materials and softens the same, the fabric softening component comprising at least one higher aliphatic acid ester selected from the group consisting of: I. an ester having the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be the same or different and are H, (--H.sub.2).sub.x OR.sub.5 or (--H.sub.2).sub.y CH.sub.3 ; R.sub.5 is H, --OCR.sub.6, [--(--CH.sub.2 --].sub.n H or [--(--CH.sub.2 --).sub.m O]--.sub.n OCR.sub.6 and --OCR.sub.6 is a higher fatty acid acyl group having 8 to 24 carbon atoms; x is an integer from 0 to 3, y is an integer from 0 to 4, m is an integer from 1 to 3, and n is an integer from 1 to 10; with the proviso (1) that only two of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be H or --(CH.sub.2).sub.y CH.sub.3 and (2) that there be at least 2 higher fatty acid acyl groups; II. an oligomer of I; and III. an ester having the formula: ##STR2## wherein R.sub.7 and R.sub.6 may be the same or different and are H or --OCR.sub.6, a is an integer from 1 to 3, b is an integer from 1 to 20 and --OCR.sub.6 has the meaning ascribed above; with the proviso that only one of R.sub.7 and R.sub.8 may be H; and a dispersing agent therefor.

Fabric softening composition based on higher fatty acid ester and

The pourability and softening performance of amidoamine fabric softeners, such as bis(tallow amidoethyl)-2-hydroxyethyl amine) is improved by blending with a quaternary diester fabric softener, such as N-methyl, N,N,N-triethanolamine ditallow ester quaternary ammonium salt. The amidoamine fabric softener includes at least 5% by weight of unsaturated higher alkyl groups. The compositions are concentrated with amounts of active softener compounds in excess of 25% by weight and, as such, may be used at low levels or maybe further diluted prior to use.

Concentrated liquid fabric softening composition

The stability and softening performance of amidoamine fabric softeners, such as bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine) is improved by protonating the amine with a neutralizing inorganic or organic acid and incorporating certain stabilizing emulsifiers, such as, N,N',N'-tris(2-hydroxyethyl)-N-tallow-1,3-diaminopropane, dimethylhydrogenated tallow amine, methyl dihydrogenated tallow amine, and oleic imidazoline). Mixtures of bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine and bis(tallow amidoethyl)-2-hydroxyethyl amine also provide improved softening and form stable aqueous dispersions. The compositions may be highly concentrated for use at low levels or for further dilution prior to use.
