This R¹Base of the parent fatty acid The average iodine value (hereinafter referred to as IV) is preferably from about 40 to about 140, More preferably from about 60 to about 130, most preferably from about 70 to about 105.   The above counter ion X^-Is any softener compatible anion, preferably a strong acid ON, such as chloride, bromide, methyl sulfate, sulfuric acid, nitric acid, etc., more preferably Is chloride or methyl sulfate.   These biodegradable quaternary ammonium fabric softening compounds include canola oil, safflower -Oil, peanut oil, sunflower oil, corn oil, soybean oil, tall oil, rice bran oil, etc. Unsaturated fatty acids obtained from such vegetable oils and / or partially hydrogenated vegetable oils, For example, oleic acid and / or fatty acids and / or hydrogenated and / or Is a group C (O) R mainly derived from partially hydrogenated fatty acids¹Can have You. Non-limiting examples of DEQAs made from fatty acids have the following approximate distribution: RU:  Other non-limiting examples of the DEQA of the present invention are as follows:  DEQA⁶Is made from soybean fatty acids and DEQA⁷Is a slightly hydrogenated beast Manufactured from fatty fatty acids.   DEQA⁸~ DEQA^TenAre made from different commercial isostearic acids.   A suitable DEQA is a separate final product made from different parts of the total fatty acid blend. All different fats represented, not only from blends of mixtures of DEQA Can also be manufactured as a single DEQA from a blend of acids (all fatty acid blends) it can. Low IV soft activators also include branched chain fatty acids such as isostearic acid. May be used if available.   Unsaturated fatty acyl groups, including polyunsaturations, exhibit surprisingly effective softening As well as good rewet properties, good antistatic properties, especially for polyunsaturated fatty acids Thanks to its excellent recovery after freezing and thawing.   Highly unsaturated substances are easier to formulate in concentrated premixes that maintain low viscosity, Therefore it is easy to process without large amounts of solvent, for example pumping, mixing etc. No. These highly unsaturated substances are present in only small amounts, such as those normally associated with such substances. About 7 to about 25% by weight of the total softener / solvent mixture, preferably about 10 to about 15%. If used together with a low molecular weight solvent, even at ambient temperature, the concentrated stable composition of the present invention is already used. It is easier to prescribe. However, when such solvents are at high levels, Shrink premix is flammable. Flammability is defined as about 100 ° F (about 38 ° C) A lower closed cup flash point. As described herein Higher boiling water-soluble solvents can be used in the preparation of the activator.   Low IV activators (40-70) typically require large amounts of high boiling water-soluble solvent B.   This ability to safely process activators at low temperatures means that it minimizes degradation. Thus, it is particularly important for polyunsaturated groups. Additional protection against degradation And softener compositions contain effective antioxidants and / or reducing agents as described below Obtained when you are.   Substituents R and R¹Are various groups such as alkoxyl or hydroxyl groups Optionally substituted, R¹Groups retain their basic hydrophobic character It will be understood that they may be linear or branched as long as possible. Branch is good To reduce the viscosity while still providing good stability, especially in mixtures of fatty acids, Highly desirable. However, in this development, more readily available linear and saturated Sum and unsaturated fatty acids can be used. Preferred compounds are general-purpose fabric softeners. A softener, ditallow dimethyl ammonium chloride (hereinafter “DTDMAC”) ) Is considered to be a biodegradable diester variation. Appropriate length Chain DEQA is a DEQA produced from a source having a high level of polyunsaturation, N, N-di (acyloxyethyl) -N, N-dimethylammonium chloride Wherein the acyl is a fatty acid having sufficient polyunsaturation, such as tallow fatty acid and And a mixture of soybean fatty acids.   The fatty acyl groups are, for example, about 50-100%, preferably about 60-98%, furthermore Preferably about 65 to about 95% unsaturated, the total level of polyunsaturated fatty acyl groups (TPU) is about 1 to about 30%, preferably about 3 to about 25%, more preferably about 5 Less than about 18%, even more preferably greater than about 10%, use less solvent. May be. The cis / trans ratio of the unsaturated fatty acyl group is important, Ratios are from 1: 1 to about 50: 1, with a minimum of 1: 1 to minimize solvent usage, preferably 1: 1. It is at least 3: 1, more preferably from about 4: 1 to about 30: 1. Low IV fat The acid can be used if it is blended with a branched chain fatty acid, e.g., isostearic acid. You.   These biodegradable fabric softeners may have a certain percentage, preferably lower, For example, it typically contains less than about 5% free fatty acids. Free fatty acids will be disclosed later Acts as a viscosity modifier as well as adding some softening effect it can.   These premixes may be used at ambient temperature and / or using high shear mixing. Without (i.e., simple mixing is sufficient), low concentrations (about 2 to about 50 % By weight, preferably about 3 to about 30%, more preferably about 4 to about 26%) It is desirable to formulate the composition as a product. However, high shear mixing and It has been found that higher temperatures and / or higher temperatures can be used if desired.   When the premix is used to formulate a highly concentrated composition, an additional advantage is The shrink composition is not flammable. Activator concentration of about 13 to about 60%, preferably About 18 to about 52% of the final composition has no risk of fire hazard, Less than about 500 cps, preferably less than about 400 cps, more preferably less than about 200 cps. It can be made to have a viscosity of less than cps. Such a composition is about 5% Less than about 4%, more preferably less than about 3%, more preferably less than about 3%. Should be.   A preferred compound is the general purpose fabric softener, ditallow dimethyl ammonium chloride. Biodegradable diester variation of Loride (hereinafter referred to as "DTDMAC") It is thought that it is. Preferably, at least about 80% of the DEQA is a diester 0 to about 20% is a DEQA monoester (eg, in Formula (1) Where m is 2 and YR¹Is an H or -C (O) OH group). Highly preferred New long chain DEQAs have relatively high levels of georail DEQA, ie, N, N-di ( Containing oleyloxyethyl) -N, N-dimethylammonium chloride It is.

The compounds used in the present invention are It is highly desirable to be relatively pure. Therefore, such failures Treating the source of fatty acids in a manner known to remove pure, e.g., controlled Before and / or after chemical modification, such as by hydrogenation and / or oxygenation Undesirable substances due to filtration, adsorption, etc., processed under atmospheric pressure with little oxygen Is desirably separated. However, the purity of the substance is Notwithstanding, this applies equally to less pure substances, with a trade-off between purity and cost. Comparisons are always made in light of the wishes and needs of consumers.   When a diester is described, as used in the present invention, it is present May be contained. For softening, no / low detergent carrier -Under bar washing conditions, the percentage of monoester is as low as possible, Preferably it should be less than about 5%. However, high anionic detergent surfactant Under detergent or detergent builder carryover conditions, small amounts of monoester are preferred. Good. The overall ratio of diester to monoester is from about 100: 1 to about 2: 1, preferably From about 50: 1 to about 5: 1, more preferably from about 13: 1 to about 8: 1.
