Compositions of this type have unexpectedly demonstrated superior softening performance and stability compared to the prior art compositions. Fabric softener compositions suitable for providing fabric softening and static control benefits during laundry are well known in the art. Such compositions generally contain softener as a component. quaternary ammonium compounds substantially insoluble in water having two long alkyl chains.

In addition, the use of several quaternized ester-amines as fabric softening agents is also well known in the art. The patent of E.U.A. No. 4.339.39I of Hoff annr et al. Per example describes a series of quaternized ester-amines having co-utility or fabric softeners. The patent of E.U.A.

EP 0 550 361 to Stepan discloses cationic compositions for treating fabrics comprising quaternary ammonium compounds which are the reaction product of a long chain fatty acid and a tertiary amine wherein the ratio of the fatty acid to the amine is from 1.T5 and 1.4. W0 91/01295 to Henkel discloses useful quaternary ammonium compounds or textile treatment agents? which are prepared by reacting fatty acids with alkanolamine and then renting them to give the quaternary compounds. The esterification reaction is carried out in the presence of an acid catalyst such as hypophosphorous acid. The final product comprises "allegedly" mono-r di-r and triester components in a ratio of 10-62-28%, but there is no publication of a process for the preparation of a final product having a high diester content. That is to say »of mass approximately 557% by weight» and low content of »tries» that is to say »of menoß of approximately 20% by weight. Finally »WO 94/14935 to Henkel discloses concentrated textile softening dispersions containing quaternary amino compounds derived from triethanolamine containing» 1 »2 or 3 fatty acyl loxieti groups. When the proportion of compounds having two fatty acyloxyethyl groups is greater than 50% by mol, these compounds have allegedly a particularly low viscosity. However, no method was disclosed in this document to achieve this level of diester and gives an indication of the triéeter content of the final product. It is therefore evident that the prior art considered hereinabove does not contemplate or suggest the quaternized diester-based softening composition containing high diester content and low trieeter content. A process for the preparation of such products is also not contemplated. According to the above »it is an object of the present invention to provide a quaternized diester product having high diester content and low triester content.

The quaternary ammonium salt mixtures of the present invention can also be used in products other than fabric softening compositions. These products can include hair care formulations »skin care formulations and the like» by the softening »lubrication» softening and the condition of said hair and / or skin when applied in effective amounts. These and other uses will be immediately apparent to one of ordinary skill in the art. Although the stability of the fabric softening composition of the present invention is such that no surfactant co-surfactants are required, these may nevertheless be included together with a wide variety of other optional ingredients. A brief limiting description of some of the optional ingredients that may be employed in the textile softening compositions of the present invention is provided below.

I.) Viscosity / Dispersability Auxiliary Materials As previously mentioned, the relatively concentrated compositions of the quaternary steres of the present invention can be prepared so that they are stable without the addition of concentration aids. Furthermore, the compositions of the present invention may require organic and / or inorganic concentrating auxiliaries to achieve even higher concentrations and / or to satisfy higher stability standards depending on the other ingredients. These auxiliary concentration materials which are typically viscosity modifiers may be needed or preferred to "ensure stability under extreme conditions" when particular active softener levels are present in the reaction to the VY.

Surfactant Assistive Materials Surfactant Assistive Materials typically fall into four categories- (1) cationic surfactants such as long chain alkyl. (2) nonionic surfactants; (3) amine oxides »and (4) fatty acids. It is also possible, of course, to use mixtures of the aforementioned auxiliary surfactant concentrates. (1) Cationic surfactants nona alkyl chain laccase Cationic surfactant agents soluble in water long chain alkyl or ester which are preferred fall generally within the following general formula - [R «| \ | < < R3) 3 > (~ wherein the group R2 is a Cß-Caa hydrocarbon group, preferably C ?a-Clβ alkyl group or the corresponding ester interrupted linking group with a short chain alkylene group (0, - C *) between the ester bond and N »and having a similar hydrocarbon group. Each R is an alkyl unsubstituted or substituted for C ^ - ^, (for example by hydroxy) or hydrogen, preferably methyl, and the counter anion) < an anion compatible with the softener such as "chlorine bromide" methyl sulfate "etc. The cationic surfactants "if present" are usually added to the solid compositions at a level from 0% to about 157% by weight, preferably from about 3% to about 15%, more preferably from about 57%. imadamente 15%. In liquid compositions, they are usually employed at a level from 0% to approximately 15%, preferably from about 0.5% to about 10%. In general, the total amount of single long chain cationic surfactant is added in an amount effective to obtain a stable composition.

The resulting levels represent the activity of the single long chain alkyl cationic surfactant agent which is added to the composition of the present invention. The ranges do not include the amount of monoester which is already present in the quaternary ammonium compound of diester. The long chain group Rz of the single long chain alkyl cationic surfactant generally contains a group having the about 10 to about 22 carbon atoms, preferably about 12 to about 16 carbon atoms for the solid compositions, and preferably about 12 to about 18 carbon atoms for the liquid compositions. This group Ra can be attached to the cationic nitrogen atom behind a group containing one or more ester, amide, ether, amine, etc., linking groups. preferably ester, which may be desirable for their hydrophilicity, biodegradability, etc. increased. Such linking groups are preferably within about 3 carbon atoms of the nitrogen atom. In the patent of E.U.A. No. 4,840,738, which is incorporated herein by reference, are disclosed to suitable biodegradable single long chain alkyl cationic surfactants. If the corresponding non-quaternary amines »any acid (preferably a mineral or polycarboxylic acid) which is added to keep the ester groups stable will also keep the amine catalyzed in the compositions and preferably during the rinsing» so that the amine has a cationic group . The pH composition is regulated (pH from about 2 to about 5, preferably from about 2 to about 4) to maintain an appropriate and effective loading density in the aqueous liquid concentrate and then in higher dilution, eg to form a less product. concentrate and / or after the addition to the rinse cycle of a laundry washing process. The main function of the water-soluble cationic surfactant is to decrease the viscosity and / or increase the dispersibility of the diester softener and it is therefore not essential that the cationic surfactant itself has substantial softening properties, although this may be the case . Also, the surfactants having only a single long chain alkyl, presumably because they have a higher solubility in water, can protect the diester softener so that they do not interfere with the anionic surfactants and / or detergency builders and are transferred to the rinse. Other cationic materials with ring structures such as alkyl imidazoline »imidazolinium» pyridine and pyridinium salts having a single alkyl chain of Ci St-C3ct can also be used. A very low pH is required to stabilize »for example the ring structures of imidazoline. Some alkyl imidazolinium ealees useful in the present invention have the general formula? wherein Y * is -C (0) -0- »-0- (0) C-» -C (0) -N (Rβ) »or -N (Rβ) -C < 0 > - in which R89 is hydrogen or an alkyl radical of Cx-C ^ RA is an alkyl radical of Ct-C ^? each of R "7- and R * are independently selected from R and R * as defined herein above for a single long chain cationic surfactant with only one R *. Some salts of alkyl pyridinium useful in the present invention They have the general formula- where R * and X ~ are as defined above. A typical material of this type is acetyl pyridinium chloride. (2) Alkoxylated nonionic surfactants Nonionic surfactants suitable as viscosity / dispereability modifiers include the addition products of ethylene and / or propylene oxide with fatty alcohols, fatty acids, fatty amines, etc. Any of the alkoxylated materials that are described < hereinafter as a nonionic surfactant.

More preferably, the chain length of the hydrocarbyl to the liquid compositions is from about 16 to about 18 atoms and for the solid compositions they form from about 10 to about 14 carbon atoms. Of the general formula for the ethoxylated nonionic surfactants of the present »Y is typically -0-» ~ C (0) - »~ C (0) N < R) - »or -C (0> N (R) R-» where R »when present» have meanings given hereinabove »and / or R can be hydrogen» and z is at least about 8 » preferably at least about 10-11.The yield and usually the stability of the softening composition decreases when less ethoxylate group is present.
