Abstract:
A conditioning detergent composition comprised of a surfactant portion comprising at least one of anionic, amphoteric, and nonionic surfactants and a conditioner portion comprising at least one branched cationic polymers and a silicone which is different from said branched cationic polymer and which is matrix soluble. The conditioning detergent composition imparts cleansing, wet detangling, dry detangling and manageability to hair and which is relatively non-irritating and thus suitable for use by young children and adults having sensitive skin and eyes. The conditioning detergent composition is able to provide such benefits in an aesthetically pleasing formulation without the need for suspending agents, opacifiers, or pearlizing agents.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates to conditioning detergent compositions suitable for use in personal cleansing application which not only impart cleansing, wet detangling, dry detangling and manageability properties to hair, but also which are relatively non-irritating and thus suitable for use by young children and adults having sensitive skin and eyes.  
         [0003]     2. Description of the Prior Art  
         [0004]     In the past, it has been considered desirable to cleanse hair and then to condition it after cleansing. For many years, it was necessary to perform these acts in two separate steps. However, with the advent of so-called “two-in-one” conditioning shampoos, it became possible to condition and cleanse simultaneously. Unfortunately, many of these two-in-one conditioning shampoos and body cleansers have proven to be relatively irritating to the eyes and skin and uncomfortable for use with children or sensitive adults. Therefore, it is an object of this invention to create a conditioning shampoo that has good cleansing ability, excellent conditioning properties and has a low degree of ocular and skin irritation.  
         [0005]     One approach to providing hair conditioning benefits to a shampoo is described in U.S. Pat. No. 5,932,202, which discloses a composition comprised of an ethoxylated alkyl sulfate surfactant combined with an amphoteric surfactant; a cationic cellulosic polymer and a water insoluble non-volatile conditioning agent. While this shampoo claims to have optimized the conditioning properties of its cellulosic polymer by selection of a particular surfactant combination, that surfactant combination is not known as being gentle to the eyes and skin. Moreover, cationic cellulosic polymers are often disadvantageously associated with leaving an “unclean” residue to the hair and skin. Further, it is necessary to use a suspending agent for the insoluble conditioning agent in order to produce an aesthetically pleasing formulation. Typically, such formulations that required the use of a stabilizer are prone to separation and are capable of yielding only opaque products.  
         [0006]     It would be desirable to have a conditioning composition that would not only impart cleansing, wet detangling, dry detangling and manageability properties to hair, but would also have a low degree of ocular and skin irritation. It would also be desirable to have such a conditioning detergent composition in a clear or translucent, aesthetically pleasing formulation without the need for adding pearlizers, opacifiers, and suspending agents thereto.  
       SUMMARY OF THE INVENTION  
       [0007]     In accordance with this invention, there is provided a conditioning detergent composition comprising: 
        a surfactant portion comprising at least one of the following: 
            1. a nonionic surfactant;     2. an amphoteric surfactant; and     3. an anionic surfactant; and    
            a conditioner portion comprising: 
            1. at least one branched cationic polymer; and     2. at least one silicone that is different from the branched cationic polymer and is matrix soluble.    
               
 
         [0015]     The composition of this invention, when used in a shampoo or body cleanser, possesses superior conditioning properties as well as one or more of the following properties: cleansing, shine, low dry static, softness, wet detangling, dry detangling, manageability, and low degree of ocular irritation. In addition, the composition may be made into various, aesthetically pleasing consumer cleansing products without the need for pearlizers, suspending agents or opacifiers.  
         [0016]     While not bound by theory, it is believed that the combination of a branched cationic polymer and a matrix soluble silicone is an improvement over current systems containing macro emulsified silicone, such as, polydimethyl siloxane, methyl terminated (dimethicone) and polydimethyl siloxane, hydroxyl terminated (dimethiconol), due to its ability to deposit on hair or skin, yet still demonstrate ease of removal, and therefore reduced build-up, upon subsequent washings. Deposition of the micro emulsified silicon can occur via several mechanisms including electrostatic charge (if the silicone is cationic) or reduced solubility upon dilution resulting in a coating effect of insoluble material on the substrate. To enhance the deposition of silicone to hair and skin, a branched, cationic polymer is added.  
         [0017]     It is believed that the branched, cationic polymer enhances deposition of the silicon via entrapment and, in some cases, association of the silicone. This effect could also occur with linear polymers, however, branched polymers are probably more effective due to their reduced packing density allowing for more physical room for entrapment and/or association. The cationic polymer entrapped or complexed silicone is then preferentially deposited to the negatively charged substrate (skin and hair) due to the attraction of the polymer cationic charge of the polymer. The reduced build-up on hair may be due to the fact that the silicone employed in this technology is soluble in the cleanser matrix (microemulsifiable). Micro emulsions, which because of their small droplet size (typically below 0.10 μm) cannot scatter light and therefore appear transparent, are formed spontaneously in conjunction with a surfactant. Any mechanical means used to mix the micro emulsion has no bearing on formation of the micro emulsion or particle size. In contrast, macroemulsions, which possess a droplet size typically greater than 0.15 μm, will scatter light due to their size and therefore appear opaque. Additionally, macroemulsions require both a surfactant to stabilize the emulsion droplets and mechanical energy to form droplets. Additional mechanical energy has the effect of lowering the droplet size. It is important to note that macroemulsions, unlike microemulsions, require a reasonable amount of mechanical energy to re-emulsify the deposited material from the substrate and wash it away. Microemulsions, on the other hand, require no mechanical energy to re-emulsify the deposited material and, therefore, can remove it easily from a substrate. During a wash cycle, the only means of mechanical action available would be the scrubbing of the hair or body with hand or bath implement. Upon repeated wash cycles that consist of removal of dirt and previously deposited material and deposition of new material, it is easy to see how a microemulsified material that is matrix soluble and requires no mechanical energy to re-emulsify might be easier to remove than a material that requires macroemulsification and the associated mechanical energy required for its removal.

Examples of suitable volatile silicones nonexclusively include trimethylsilylamodimethicone, phenyl trimethicone, polydimethylsiloxane having a viscosity less than about 5 cSt, polydimethylcyclosiloxanes, hexamethyldisiloxane, cyclomethicone fluids such as such as those available commercially from Dow Corning Corporation of Midland, Mich. under the tradename, “DC-345” and mixtures thereof.  
         [0114]     Examples of suitable nonvolatile silicone conditioning agents nonexclusively include organo-substituted polysiloxanes, which are either linear or cyclic polymers of monomeric silicone/oxygen monomers and which nonexclusively include cetyl dimethicone; cetyl triethylammonium dimethicone copolyol phthalate; dimethicone copolyol; dimethicone copolyol lactate; hydrolyzed soy protein/dimethicone copolyol acetate; silicone quaternium 13; stearalkonium dimethicone copolyol phthalate; stearamidopropyl dimethicone and mixtures thereof; polyaryl siloxanes such as phenyl trimethicone; polyalkyl siloxanes such as the amino substituted amodimethicones; polyalkylarylsiloxanes; and derivatives there of and mixtures thereof.  
         [0115]     Particularly suitable matrix soluble silicones for use in the invention include trimethylsilylamodimethicone, dimethicone copolyol, and amodimethicone, such as, DOW Corning 2-8566 Aminio Fluid available from Dow Corning Corporation and mixtures thereof.  
         [0116]     Preferably, the conditioning detergent composition of the present invention is visually clear and is free of or substantially free of pearlizing agents, opacifiers, or suspending agents. By “substantially free of,” it is meant that the conditioning detergent compositions contains, based upon the total weight of the conditioning detergent composition, no more than 1.0 percent, preferably no more than 0.5 percent, and more preferably no more than 0.1 percent of a pearlizing agent, opacifier, or suspending agent. We have unexpectedly found that the conditioning detergent composition of the present invention results in an aesthetically pleasing formulation that possesses improved detangling and conditioning properties in the absence of pearlizing agents, opacifiers, and suspending agents. Without wishing to be bound by theory, we believe that the resulting formulations do not phase-separate as a result of the interaction between the surfactants and the silicones with the unique structure of the branched quaternary cationic polymer. By not having to use such stabilizing agents, et al., the conditioning detergent composition of the present invention may be colorless, clear, or translucent.  
         [0117]     In embodiments wherein an opaque composition may be desired, the composition of the present invention may also include one or more optional ingredients nonexclusively including a pearlescent or opacifying agent, or a thickening agent. Other optional ingredients include secondary conditioners, humectants, chelating agents, and additives which enhance their appearance, feel and fragrance, such as colorants, fragrances, preservatives, pH adjusting agents, and the like. The pH of the conditioning detergent compositions of this invention is preferably maintained in the range of from about 5 to about 7.5, and more preferably from about 5.5 to about 7.2.  
         [0118]     Commercially available pearlescent or opacifying agents which are capable of suspending water insoluble additives such as silicones and/or which tend to indicate to consumers that the resultant product is a conditioning shampoo are suitable for use in this invention. The pearlescent or opacifying agent is present in an amount, based upon the total weight of the composition, of from about 0 percent to about 3 percent, preferably from about 0.25 percent to about 2.5 percent, and more preferably, from about 0.5 percent to about 1.5 percent. Examples of suitable pearlescent or opacifying agents include, but are not limited to mono or diesters of (a) fatty acids having from about 16 to about 22 carbon atoms and (b) either ethylene or propylene glycol; mono or diesters of (a) fatty acids having from about 16 to about 22 carbon atoms (b) a polyalkylene glycol of the formula

         [0123]     In a preferred embodiment, the pearlescent or opacifying agent is introduced to the conditioning detergent composition as a pre-formed, stabilized aqueous dispersion, such as that commercially available from Henkel Corporation of Hoboken, N.J. under the tradename, “Euperlan PK-3000.” This material is a combination of glycol distearate (the diester of ethylene glycol and stearic acid), Laureth-4 (CH 3 (CH 2 ) 10 CH 2 (OCH 2 CH 2 ) 4 OH) and cocamidopropyl betaine and preferably is in a weight percent ratio of from about 25 to about 30: about 3 to about 15: about 20 to about 25, respectively.  
         [0124]     Commercially available thickening agents which are capable of imparting the appropriate viscosity to the conditioning detergent compositions are suitable for use in this invention. If used, the thickener should be present in the conditioning detergent compositions in an amount sufficient to raise the Brookfield viscosity of the composition to a value of between about 500 to about 10,000 centipoise. Examples of suitable thickening agents nonexclusively include: mono or diesters of 1) polyethylene glycol of formula
