FIELD OF THE INVENTION

The present invention relates to conditioning shampoo compositions which both cleanse the hair and condition the hair These compositions comprise a detersive surfactant a fatr compound selected trom the group consisting of fatty alcohols, fatty acids, fattv alcohol derivatives, fatty acid derivatives, and mixtures thereof, a hair conditioning agent selected from the group consisting of nonvolatile dispersed silicone conditioning agents, hydrocarbon conditioning agents, water soluble cationic poK meπc conditioning agents, canonic surfactants, and mixtures thereof and water The present invention also relates to methods for cleansing and conditioning the hair

BACKGROUND OF THE INVENTION Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scaip The soiling of hair causes it to have a dirty feel and an unattractive appearance The soiling of the hair necessitates shampooing with frequent regularity Shampooing cleans the hair by removing excess soil and sebum However, shampooing can leave the hair in a wet. tangled, and generally unmanageable state Once the hair dries, it is often left in a drv rough, iusterless or frizzv condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components The hair can further be left ith increased levels ot static upon drvuig, which can interfere with combing and result in a condition commonlv referred

A vanety of approaches have been developed to alleviate these after-shampoo problems These approaches range from post-shampoo application of hair conditioners such as leave-m and rinse-off products, to hair conditioning shampoos which attempt to both cleanse and condition the hair from a single product Hair conditioners are typically applied m a separate step following shampooing The hair conditioners are either rinsed-off or left-in. depending upon the type of product used Hair conditioners, however, have the disadvantage of requiring a separate and inconvenient treatment step Conditioning shampoos, I e shampoos which both cleanse and condition the hair, are highly desirable products because they are convenient for consumers to use

In order to provide hair conditioning benefits in a cleansing shampoo base, a wide variety of conditioning actives have been proposed However, many of these actives have the disadvantage of leaving the hair feeling soiled or coated, of interfering with the cleansing efficacy of the shampoo, or of yielding a resultant shampoo with poor shelf stability

It has suφrisingly been found in the present invention that stable shampoo compositions having good cleansing and conditioning ability without leaving the hair feeling soiled or coated can be achieved These compositions provide improved wet hair conditioning benefits such as smoothness and ease of combing compared to conventional conditioning shampoos These compositions also provide improved dry hair conditioning benefits such as leaving the hair feeling soft, smooth, and moistened These dry hair benefits can also result in hair that looks shiny These compositions are achieved by utilizing the combination of a detersive surfactant, a compound selected from the group consisting of fatty alcohols, fatty acids, derivatives of fatty alcohols, derivatives of fatty acids, and mixtures thereof, a hair conditioning agent selected from the group consisting of nonvolatile dispersed silicone conditioning agents, hydrocarbon conditioning agents, water soluble cationic polymeric conditioning agents, cationic surfactants, and mixtures thereof Preferred embodiments include compositions which further comprise a polyalkylene glycol

It is therefore an object of the present invention to provide conditioning shampoo compositions, i e compositions which both cleanse and condition the hair from a single product It is another object of the present invention to provide compositions which do not leave the hair feeling coated, heavy, or soiled

It is another object of the present invention to provide compositions which provide improved wet hair conditioning benefits such as smoothness and ease of combing

It is an object of the present invention to provide compositions which provide improved dry hair conditioning benefits such as leaving the hair feeling soft and smooth and looking shiny

It is another object of the present invention to provide methods for cleansing and conditioning the hair utilizing a single composition

METHOD OF USE

The conditioning shampoos of the present invention are used in a conventional manner for cleansing and conditioning the hair on human heads An effective amount of the shampoo composition, typically from about 1 gram to about 50 grams, and preferably from about 1 gram to about 20 grams, is applied to the hair Preferably the hair has been wetted with water before application of the shampoo Application of the shampoo typically includes working the composition through the hair, generally with the hands and fingers, to generate a lather The shampoo product is then typically πnsed from the hair with water This method for cleansing and conditioning the hair comφises the steps of

(a) wetting the hair with water,

(b) applying an effective amount of the conditioning shampoo of the present invention to the hair,

(c) shampoo the hair with the composition, i e working the composition in contact with the hair and into a lather, and

(d) πnsmg the conditioning shampoo from the hair using water

These steps can be repeated as many tunes as desired to achieve the cleansing and conditionmg benefit sought

EXAMPLES The following examples further describe and demonstrate embodiments within the scope of the present mvention The examples are given solely for the puφose of illustration and are not to be constured as limitations of the present mvention, as many variations thereof are possible without departing from the spirit and scope ofthe invention

Ingredients are identified by chemical or CTFA name Method of Preparation Examples I-X

The conditioning shampoo compositions of the present invention can be prepared by using conventional mixmg and formulatmg techniques The conditionmg shampoo compositions illustrated

in Examples I-X are prepared in the following manner All percentages are based on weight unless otherwise specified

First, a silicone premix is prepared having the following composition by weight at least about 50% dimethicone, from about 5% to about 15% ammonium laureth-3 sulfate, and the remainder water It should be noted that the ammonium laureth-3 sulfate is added in this premix, in the main body of the composition, and after heat processing The premix is formed by high sheer mixing until the desired silicone particle size is achieved

For each of the compositions illustrated in Examples I-X, polyquaternιum- 10 and the polyethylene glycol, when present, are dispersed in water to give a solution This solution, the mineral oil, and approximately one-third of the total ammonium laureth-3 sulfate are combined in a mixing tank and heated to about 75°C with slow agitation to form a solution of the surfactant The cocamide MEA, any fatty alcohols, fatty acids, and their derivatives, as applicable, are added to this tank and dispersed with stirring Next, the ethylene glycol distearate is added to the vessel with mixing After the addition and mixing of the ethylene glycol distearate is completed, usually after about 5 to 20 minutes, any additional cationic surfactants and the preservatives are added with mixing The resultant mixture is passed through a heat exchanger, cooled to about 35°C, and collected in a finishing tank Next, the remainder of the ammonium laureth-3 sulfate, the ammonium lauryl sulfate, any additional surfactants, the silicone premix, and any other remaining ingredients are added with mixing to form a homogeneous mixture As necessary, the viscosity of the resultant composition can be adjusted by the addition of appropriate amounts of ammonium xylene sulfonate or additional sodium chloride Preferred viscosities range from about 2000 to about 9000 centistokes at 25°C, as measured by a Wells-Brookfield viscometer equipped with a cone number CP 41 at a measurmg speed of 1 φm

The compositions illustrated m Examples I-X, all of which are embodiments of the present invention, are useful for both cleansing and conditionmg the hair from a single product In alternative embodiments, the ammonium laureth-3 sulfate and/or the ammonium lauryl sulfate are replaced with equal weights of sodium laureth-3 sulfate and sodium lauryl sulfate, respectively
