ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to styling shampoo compositions which contain select combinations of cationic deposition polymer and cationic styling polymers to improve the styling performance of the composition, especially when used in select surfactant matrices such as combinations of zwitterionic and anionic surfactants.
BACKGROUND OF THE INVENTION
Many hair shampoo compositions provide acceptable cleaning but provide little or no styling benefits, e.g., body, hold, curl retention, stiffness. To realize such benefits, separate cleaning and styling products are often used.
Recently, hair shampoo compositions have been developed which can provide cleaning and styling performance from a single product. Many of these products contain styling polymers in a compatible shampoo base. To prepare such products, styling polymers can be incorporated into the shampoo base by first dissolving the polymer in a liquid carrier and then adding the polymer/liquid carrier premix to the surfactant phase of the composition. Alternatively, the styling polymer can be dispersed in the surfactant phase of the shampoo composition, and deposited onto the hair to form a thin film on the hair shaft. The polymers provide improved hairstyle benefits such as body, hold, and curl retention. However, some styling polymers, whether deposited onto the hair via a liquid carrier or by dispersion, leave the hair feeling sticky or tacky.
It has now been found that a combination of cationic deposition polymers and select organic cationic styling polymers can be incorporated into shampoo compositions containing select surfactant matrices to improve the styling performance of such compositions. This combination is especially effective in providing both conditioning and styling performance without leaving the hair feeling unduly coated, dirty, sticky, or tacky to the touch. The organic cationic styling polymers defined herein are especially effective in helping provide wet hair conditioning as well as hair styling performance when used in combination with the shampoo matrix defined herein.
In view of the foregoing, it is therefore an object of the present invention to provide a styling shampoo composition with improved styling performance. It is a further object of the present invention to provide improved hairstyle benefits such as hold, body, and curl retention from a styling shampoo composition containing a combination of cationic deposition polymer and organic cationic styling polymer. It is yet another object of the present invention to provide such a composition that also provides some hair conditioning benefits without leaving the hair feeling unduly coated, dirty, sticky or tacky to the touch.
SUMMARY OF THE INVENTION
The present invention is directed to styling shampoo compositions which comprise from (a) from about 5% to about 50% by weight of a surfactant component selected from the group consisting of a combination of an anionic surfactant and an amphoteric surfactant, and a combination of an anionic surfactant and a zwitterionic surfactant; (b) from about 0.025% to about 3% by weight of a cationic deposition polymer having a cationic charge density of from about 0.2 meq/gram to about 2 meq/gram and which is selected from the group consisting of cationic cellulose polymers, cationic guar gum derivatives, and mixtures thereof; (c) from about 0.5% to about 10% by weight of an organic cationic hair styling polymer having a cationic charge density of greater than about 2 meq/gram to less than about 4.75 meq/gram; and (d) from about 27% to about 94.5% by weight water.
It has been found that select organic cationic styling polymers, preferably Polyquaternium-16, can provide improved styling performance from a shampoo composition when used in combination with a cationic deposition polymer, especially when the cationic polymer combination is also used in combination with select surfactant combinations in the shampoo composition defined herein. The organic cationic styling polymers provide styling benefits such as improved body, hold, and curl retention.
DETAILED DESCRIPTION OF THE INVENTION
The styling shampoo compositions of the present invention comprise organic cationic styling polymers which provide the composition with improved styling performance. The styling polymers herein are soluble in water or dispersible in the surfactant phase of the shampoo composition.
The term “water-soluble” as used herein refers to any material that is sufficiently soluble in water to form a substantially clear solution to the naked eye at a concentration of about 0.2% by weight, preferably at about 0.5% by weight, even more preferably at about 1.0% by weight of the material in water at 25° C.
The term “water-insoluble” as used herein refers to any material that is not sufficiently soluble in water to form a substantially clear solution to the naked eye at a concentration of about 0.2% by weight, preferably at about 0.1% by weight of the insoluble material at 25° C.
The styling shampoo compositions of the present invention can comprise, consist of, or consist essentially of the elements and limitations of the invention described herein, as well as any of the additional or optional ingredients, components, or limitations described herein.
All percentages, parts and ratios are by weight of the total composition, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the specific ingredient level and, therefore, do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified.
Surfactant Component
The styling shampoo compositions of the present invention comprise a surfactant component to provide cleaning performance to the composition. The surfactant component in turn comprises a combination of an anionic surfactant and a zwitterionic surfactant, or a combination of an anionic surfactant and an amphoteric surfactant. Such surfactants should be physically and chemically compatible with the essential components described herein, or should not otherwise unduly impair product stability, aesthetics or performance.
Suitable anionic surfactants for use in the styling shampoo composition herein include those which are known for use in hair care or other personal care cleansing compositions. The concentration of the anionic surfactant in the styling shampoo composition should be sufficient to provide the desired cleaning and lather performance, and generally ranges from about 5% to about 50%, preferably from about 6% to about 30%, more preferably from about 7% to about 25%, even more preferably from about 8% to about 18%, by weight of the composition.
Preferred anionic surfactants suitable for use in the styling shampoo compositions are the alkyl and alkyl ether sulfates. These materials have the respective formulae ROSO

M, wherein R is alkyl or alkenyl of from about 8 to about 18 carbon atoms, x is an integer having a value of from 1 to 10, and M is a cation such as ammonium, alkanolamines, such as triethanolamine, monovalent metals, such as sodium and potassium, and polyvalent metal cations, such as magnesium, and calcium. Solubility of the surfactant will depend upon the particular anionic surfactants and cations chosen.
Preferably, R has from about 8 to about 18 carbon atoms, more preferably from about 10 to about 16 carbon atoms, even more preferably from about 12 to about 14 carbon atoms, in both the alkyl and alkyl ether sulfates. The alkyl ether sulfates are typically made as condensation products of ethylene oxide and monohydric alcohols having from about 8 to about 24 carbon atoms. The alcohols can be synthetic or they can be derived from fats, e.g., coconut oil, palm kernel oil, tallow. Lauryl alcohol and straight chain alcohols derived from coconut oil or palm kernel oil are preferred. Such alcohols are reacted with between about 0 and about 10, preferably from about 2 to about 5, more preferably about 3, molar proportions of ethylene oxide, and the resulting mixture of molecular
