Abstract:
The invention relates to a process for conditioning and cleaning hair, which comprises contacting the hair with an effective conditioning amount of a series of novel salt complexes. These complexes provide outstanding conditioning effects to the hair and are very mild to the eye. The complexes are made by neutralizing a fatty ammonium compound that is cationic with an anionic compound, producing a salt complex. Optionally, the complex can be combined with dimethicone copolyol to produce extremely mild products suitable for use in shampoos, body washes, and cleanser. The mildness makes these compounds of particular interest in baby shampoos.

RELATED APPLICATION 
     This application is a continuation in part of co-pending Ser. No. 09/483,899 filed Jan. 11, 2000. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a process for conditioning and cleaning hair which comprises contacting the hair with an effective conditioning amount of a series of novel salt complexes. These complexes provide outstanding conditioning effects to the hair and are very mild to the eye. The complexes are made by neutralizing a fatty ammonium compound that is cationic with an anionic compound, producing a salt complex. Optionally, the complex can be combined with dimethicone copolyol to produce extremely mild products suitable for use in baby shampoos. The compounds of the present invention are water soluble, non-irritating to the eye and skin and are well suited to personal care applications. 
     2. Arts and Practices 
     Fatty quaternary compounds commonly called quats, are tetrasubstituted ammonium compounds where each of the four groups on nitrogen are a group other than hydrogen. If any hydrogen groups are present, the compounds are not quaternary amines, but rather are primary or secondary amines. 
     The most commonly encountered substituents are alkyl and alkyl amido groups. There are several classes of quats. The most important are (a) alkyl tri methyl quats for example cetyltrimonium chloride, (b) alkylamidopropyl dimethyl quats like stearylamidalkonium chloride and (c) di alkyl, di methyl quats for example dicetyldimonium chloride and (d) alkyl, benzyl, Di methyl quats like stearalkonium chloride. 
     There are several undesirable attributes of fatty cationic products. 
     1. Fatty Quaternary compounds are incompatible with anionic surfactants since an insoluble complex frequently is formed when the two types of materials are combined. 
     2. Many fatty Quaternary Compounds are eye irritants. The material is minimally irritating to the eyes at concentrations of 2.5%, which limits the concentration which is useful if low irritation is a requirement. 
     3. Fatty quats are generally hydrophobic and when applied to substrate can cause a loss of absorbance of the substrate. It is not an uncommon situation for a traveler to a hotel to encounter a very soft towel that totally fails to absorb water. This is because the fatty quaternary gives softness but being hydrophobic also prevents re-wet. This situation also can be observed on hair, the conditioner becomes gunky on the hair and has a tendency to build up. 
     We have learned that many of these negative attributes can be unexpectantly mitigated by making fatty complexes with carboxy fatty alcohol alkoxylates. The preferred complex has to have a molecular weight of over 1000 molecular weight units to obtain the most effective irritation mitigation. The mitigation of irritation, the improved water solubility and the skin feel make the compounds of the present invention highly desirable in personal care applications, Thus the present invention relates to a process for conditioning and cleaning hair which comprises contacting the hair with an effective conditioning amount of said series of novel salt complexes. Optionally, the complex can be combined with dimethicone copolyol to produce extremely mild products suitable for use in baby shampoos. The effective conditioning concentration for the process of the present invention runs between 0.01 and 10.0% by weight of the shampoo. The preferred is 0.2 to 2.0% by weight.

     Complexation 
     The carboxy fatty alcohol alkoxylate (examples 9-32) and the cationic compound (examples 33-52) are blended into water to make up a concentration of between 20-70%. The preferred range is 30-50% by weight. The pH of the resulting mixture is then adjusted to between 5 and 9. The lower pH is preferred for skin care products, the higher for hair care products. The complex forms in aqueous solution and the counter ion on the cationic material remains in the solution as inorganic salt. 
     Example 53 
     suitable vessel is added 840.0 grams of water. Next 491.0 grams of anionic pound Example 9 is added under agitation Next 209.0 grams of cationic pound 33 is added. The pH is adjusted to 7.0 with KOH. The complex is as prepared. 
     Examples 54-76 
     Example 53 is repeated, only this time the specified amount of water. Next the specified amount of the specified anionic compound is added. Next the specified amount of the specified cationic compound is added. The pH is adjusted to 7.0 with KOH. The complex is used as prepared.

     Applications Evaluation 
     Control Compounds 
     Stearalkonium Chloride is an excellent conditioning agent having outstanding substantivity to hair. It has detangling properties, improves wet comb when applied after shampooing. The FDA formulation data for 76 reports the use of this material in 78 hair conditioners, eight at less than 0.1%, eighteen at between 0.1 and 1.0% and 52 at between 1 and 5%. 
     Cetyltrimonium Chloride, or CTAC, is a very substantive conditioner which in addition having a non-greasy feel, improves wet comb and also provides a gloss to the hair. It is classsified as a severe primary eye irritant. Therefore its use concentration is generally at or below 1%. 
     Eye Irritation 
     Eye irritation is a major concern in the formulation of personal care products, particularly when working with quats. Primary eye irritation using the protocol outlined in FHSLA 16 CFR 1500.42 The products were tested at 25% actives. The results were as follows:
