摘要： Biodegradable fabric softener compounds that contain ester linkages a substantial level of polyunsaturation in the hydrophobic chains. The compounds can be used to form fabric softening compositions that are aqueous dispersions of the compounds or clear compositions. These compositions have a desirable low viscosity and recover, after freezing and thawing to have a stable low viscosity.
摘要翻译：含有酯键的可生物降解的织物柔软剂化合物在疏水链中具有相当程度的多不饱和度。这些化合物可用于形成作为化合物或透明组合物的水性分散体的织物柔软组合物。这些组合物具有所需的低粘度，并且在冷冻和解冻之后恢复以具有稳定的低粘度。

摘要： Fabric softener compounds having the formula: [RC(O)]nN+(R1)mX− wherein each R in a compound is a C6-C22 hydrocarbyl group, preferably having an IV from about 70 to about 140 based upon the IV of the equivalent fatty acid, n is a number from 1 to three on the weight average in any mixture of compounds, each R1 in a compound is a C1-3 alkyl or hydroxy alkyl group, the total of n and the number of R1 groups that are hydroxyethyl groups equaling 3, n+m=4 and X is a softener compatible anion, preferably methyl sulfate, the compound, or mixtures of such compounds, having (a) either a Hunter “L” transmission of at least about 85, typically from about 85 to about 95, preferably from about 90 to about 95, more preferably above about 95, if possible, (b) only non-detectable levels, at the conditions of use, of odorous compounds selected from the group consisting of: isopropyl acetate, which should be, less than about 5, preferably less than about 3, and more preferably less than about 2, &eegr;g/L.; 2,2′-ethylidenebis(oxy)bispropane, which should be less than about 200, preferably less than about 100, more preferably less than about 10, and even more preferably less than about 5, &eegr;g/L.; 1,3,5-trioxane, which should be less than about 50, preferably less than about 20, more preferably less than about 10, and even more preferably less than about 7, &eegr;g/L.; and/or each short chain fatty acid (4-12, especially 6-10, carbon atoms) ester, especially methyl esters, which should be less than about 4, preferably less than about 3, and more preferably less than about 2, &eegr;g/L. or (c) preferably, both. The fabric softener actives are preferably prepared in the presence of chelating agent and/or antioxidant, as disclosed herein. Such materials are new. Solvents can be present.
