     2. DESCRIPTION OF THE PRIOR ART 
     Quaternary ammonium compounds and tertiary amine salts of long-chain acid compounds are well known products in the chemical literature. 
     The use of quaternary ammonium compounds has been extensive in hair rinse formulations. A recent literature search does not disclose the use of tertiary amine salts of long-chain acid compounds in any hair rinse formulations. 
     The use of quaternary ammonium compounds in conjunction with tertiary amine salts of long-chain acid compounds was not found in any search involving such a combination for use in skin and hair conditioner formulations. 
     U.S. Pat. No. 30,874 to Dasher et al. describes the use of quaternary ammonium compounds in the pretreatment of hair before useing an anionic shampoo. 
     Hair cream rinse formulations containing quaternary ammonium salts have been described in U.S. Pat. No. 3,959,461 by Bailey et al. 
     U.S. Pat. No. 4,096,243 by Feinland et al. describes a composition for lightening hair using a quaternary amine. 
     Liquid hair rinse containing a quaternary ammonium salt and a synthetic secondary alcohol is described in U.S. Pat. No. 4,165,369 by Watanabe et al. 
     U.S. Pat. No. 4,187,289 by Eckhardt deals with the use of diester/amine adducts and quaternary ammonium salts as after-rinse softeners and after-shampoo hair conditioners. 
     A hair conditioning article and its use is described in U.S. Pat. No. 4,206,195 by Bolich et al. 
     The use of quaternary ammonium compounds in hair conditioner formulations is known in the art. Their blend with tertiary amine salts of long-chaim acid compounds and their blend in varying ratios introduces uniqueness in properties and uses in this invention. 
     OBJECTS &amp; SUMMARY OF THE INVENTION 
     It is the object of this invention to provide novel physical compositions of quaternary ammonium compounds and tertiary amine salts of long-chain acid compounds having a unique property making these compositions uniquely suitable in various hair and skin conditioner formulations. 
     It is the further objects of this invention to provide mixtures of quaternary ammonium commpounds and tertiary amine salts of long-chain acid compounds in varying weight-to-weight ratios of 60/40 to 90/10 respectively. 
     It is believed that the uniqueness of this invention is the use of the combination of quaternary ammonium compounds and tertiary amine salts of long-chain acid compounds which synergistically enhance each component&#39;s unique properties. 
     It is believed that the mixture of the two compounds together uniquely enhance the properties of each other. By mixing a water soluble quaternary ammonium compound with an oil soluble tertiary amine salt of long-chain acids a unique system unknown previously in skin and hair conditioner formulations is formed. The oil soluble salt moiety plasticizes the crisp film left by the water soluble moiety as it adds its own anti-tangle emollient property in synergistic fashion. 
     It is further believed that these self-emulsifiable and self-dispersing compositions in these inventions have the surfactant, emollient, anti-static, anti-tangle, lubricant, and film forming properties which make the compositions particularly suited for hair and skin conditioner formulations. 
     The preferred embodiment of this invention is as follows: 60%/40% weight-to-weight ratio of a quaternary ammonium compound/tertiary amine salts of long-chain acid compounds where the quaternary ammonium compound has the following structure: ##STR5## Where: ##STR6## R 2  =R 21  =CH 3  --; R 3  =R 31  =C 2  H 5  -- and the tertiary amine salts of long-chain acids has the following structure: ##STR7## Where: R 4  =C 12  H 25  --; R 5  =R 6  =CH 3  --; ##STR8## Where p+q=14. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Quaternary ammonium compounds are well known in the literature. Their formation is usually by a reaction of an alkylhalide with ammonia with subsequent reaction of the amine produced with another alkylhalide to produce the amine of the next higher class as follows: ##STR9## 
     In the instant invention, the preferred embodiment of the invention, the quaternary ammonium compound is a sulfate produced as follows: 
     Sunflower Seed Oil or Safflower Oil whose major reactive constituent is linoleic acid (V) is reacted with dimethyl amino propylamine (VI) in the presence of a catalyst (either Sodium Methylate or Sodium Borohydride) to produce the corresponding amide at temperatures between 125°-165° C. at pressures of 1 to 2 atmospheres to produce the corresponding amide (VII). ##STR10## 
     This amide (VII) is then reacted with diethyl sulfate at ambient pressure under nitrogen at a temperature of 60°-75° C. to produce the quaternary ammonium sulfate. ##STR11## Where: ##STR12## R 2  =R 21  =CH 3  --; R 3  =C 2  H 5  --. 
     Tertiary amine salts of long-chain acids are known. They have the formula ##STR13## wherein R 4  is selected from the group consisting of saturated and unsaturated aliphatic groups containing from about 8 to about 22 carbon atoms, ##STR14## RN(CH 3 )CH 2  CH 2  CH 2  --, RN(CH 2  CH 2  OH)CH 2  CH 2  --, ##STR15## CH 3  O[CH 2  CH(CH 3 )O] 1-5  CH 2  CH 2  CH 2  --, H[O(CH 3 )CHCH 2  ] 3-8 , H[O(CH 3 ) CHCH 2  ] 3-8  OHC 2  CH 2  --, RCHOHCH 2 , and ROCH 2  CH 2  CH 2 , wherein R represents a saturated or unsaturated aliphatic group containing from about 8 to 22 carbon atoms; R 6  is selected from the group consisting of saturated and unsaturated groups containing from one to about two carbon atoms and H(OCH 2  CH 2 ) 1-15 , R 5  is selected from the group consisting of saturated and unsaturated aliphatic groups containing from about 1 about 22 carbon atoms, ##STR16## RN(CH 3 ) 2  CH 2  CH 2  CH 2  --, RN(CH 2  CH 2  OH)CH 2  CH 2  CH 2  --,   CH 3  O[CH 2  CH(CH 3 )O] 1-5  CH 2  CH 2  CH 2  --, H[O(CH 3 )CHCH 2  ] 3-8 , H[O(CH 3 )CHCH 2  ] 3-8  OCH 2  CH 2  --, RCHOHCH 2 , ROCH 2  CH 2  CH 2 , saturated and unsaturated groups containing from one to about two carbon atoms and H(OCH 2  CH 2 ) 1-15 , and R 7  is selected from the group consisting of  RCH═CH 2  SO 3  --, RCONHCH(CH 3 )CO 2  --, ROSO 3  --, RC 6  H 5  SO 3  --, RNHCOCH═CHCO 2  --, isostearic acid residue, ricinoleic acid residue, and dimer acid residue, wherein R represents a saturated or unsaturated aliphatic group containing from about 8 to about 18  carbon atoms. 
     The preferred embodiment of the invention uses dimethyl lauramine isostearate but any of the above tertiary amine salts of long-chain acids may be used. 
     Dimethyl lauramine isostearate is produced by reacting dimethyl lauramine (X) with isostearic acid (XI) under high temperature and vacuum to produce a tertiary amine salt. ##STR17## 
     VIII and XII are physically blended by mixing together and stirring in warm environment to give various weight-to-weight ratios of VIII/XII 60/40 to 90/10, the preferred embodiment being 60/40 of VIII/XII. 
     This blending gives formulations using these compositions their unique properties including: self-emulsification, emollient properties, surfactant properties, anti-tangle properties, anti-static properties, film forming properties, and lubricating properties. 
     These unique properties make these compositions in this invention applicable to hair and skin conditioner formulations.
