This invention relates generally to hair care compositions and, more particularly, to shampoos and conditioners for dyed or color-treated hair. The shampoos and conditioners provide enhanced effectiveness in retaining the dye or colorant in the hair and protecting the dye or colorant from fading or washing-out.
Various compositions and methods for color treating hair by applying artificial colorant or dye are well known and employed by many women, and also some men. Retaining the as-applied color of the treated hair is a common problem. For instance, as a result of applying colorant or dye, the hair exhibits a particular color and/or shine. However, this color and/or shine exhibited immediately after applying the colorant or a short time thereafter begins to fade or wash-out as a result of applying shampoo and conditioner to the color-treated hair during washing and conditioning. Generally, surfactants which are typically present in many known shampoo and conditioner formulations perform a wetting function that provides moisture into the hair shaft and facilitates removal of the dye molecules during the rinsing process. Thus, the artificial dye applied to the hair in the color treatment process is disrupted and subsequently has a tendency to be removed during washing, rinsing and conditioning of the hair over a period of time.
Retaining artificial dye applied to hair and minimizing color fading are highly desirable features in hair care products. Several anti-fading products are commercially available including anti-fading shampoos and conditioners. Some of these products contain silicones such as dimethicone and amodimethicone, which are believed to improve color retention.
Certain shampoos and conditioners known in the art are formulated for use by commercial salons and the professionals employed by these salons. It is typically believed by the consumer that hair care products targeted for use by the professional salon industry are a special and improved category of shampoos and conditioners as compared to shampoos and conditioners sold “over the counter” directly to the consumer. However, in both categories, e.g., direct-to-consumer and salon professionals, there are a wide variety of shampoo and conditioner products designed, formulated and targeted for use with color-treated hair. These products which are particularly useful for color-treated hair typically contain one or more ingredients that may be effective to enhance the retention of artificial dye which has been applied to color-treated hair. It is a desire and objective of both the consumer and the product manufacturer to retain for as long as possible the initial color exhibited immediately following color treating of the hair. Thus, there is a need in the art for compositions and methods to prevent the artificial dye from washing-out or fading as a result of subsequent washing and conditioning steps applied to color-treated hair.
It is further understood that many of the products that are advertised and sold specifically for color-treated hair are not as effective as desired at color or dye retention. Thus, there is room for improvement and a desire to develop hair care products, such as shampoos and conditioners, that are even more effective at reducing fade and wash-out, and improving color retention.
These needs and others which will become apparent from the following description are achieved by the invention. In one aspect, the invention provides a hair care composition including a cationic terpolymer of vinylpyrrolidone, dimethylaminopropyl methacrylamide, and methacryloylaminopropyl lauryldimonium chloride, quinoa and a first silicone.
The color-treated hair has applied thereto an artificial dye and the hair care composition may be effective to at least partially prevent the artificial dye from fading and washing out.
In certain embodiments, the hair care composition is selected from the group consisting of shampoos and conditioners.
The first silicone can be an anionic silicone and in certain embodiments, may be selected from the group consisting of silicone quaternium-16, undeceth-11, butyloctanol, undeceth-5, and mixtures thereof.
The composition further can include a second silicone, such as but not limited to a silicone amine which may include bis-isopropylamino-PG-propyl dimethicone/bis-isobutyl PEG-14 copolymer and polysorbate 20. In certain embodiments, the second silicone includes a mixture of bis-isopropylamino-PG-propyl dimethicone/bis-isobutyl PEG-14 copolymer, polysorbate 20 and butyloctanol.
In certain embodiments, the first silicone includes a mixture of silicone quaternium-16, undeceth-11, butyloctanol, undeceth-5, and the second silicone includes a mixture of bis-isopropylamino-PG-propyl dimethicone/bis-isobutyl PEG-14 copolymer, polysorbate 20 and butyloctanol.
In another aspect, the invention provides a method of preparing a hair care composition for application to color-treated hair, the composition having improved color retention. The method includes combining the following components: a cationic terpolymer of vinylpyrrolidone, dimethylaminopropyl methacrylamide, and methacryloylaminopropyl lauryldimonium chloride, quinoa and a first silicone.
In still another aspect, the invention provides a method of improving the retention of artificial color for color-treated hair during washing and rinsing of the color-treated hair. The method includes preparing a composition by combining the following components: a cationic terpolymer of vinylpyrrolidone, dimethylaminopropyl methacrylamide, and methacryloylaminopropyl lauryldimonium chloride, quinoa and a first silicone; wetting the color-treated hair; applying the composition to wetted color-treated hair and then rinsing with water to at least partially remove the composition from the color-treated hair.
The invention relates generally to compositions for keratin fibers, in particular for human keratin fibers and more specifically, for human hair. The invention also includes methods for preparing the compositions and uses of the compositions for hair care. In particular, the compositions, methods and uses of the invention are directed to hair that is treated with artificial dye or colorant to produce color-treated hair. The application of artificial dye or colorant to human hair is widely known and practiced in the art. For example, there are a wide variety of known oxidation-dyeing compositions for hair which typically include an oxidation dye in a medium suitable for dyeing hair. Further, it is known that subsequent washing and rinsing of the color-treated hair can result in fading and washing out of the artificial dye from the hair. Furthermore, it is known in the art that there is a desire and need to develop hair care products that minimize the extent and effects of fade and wash-out. The hair care compositions, methods and uses of the invention are effective to increase or improve retention of artificial dye in hair even after subjecting the color-treated hair to multiple washing and rinsing steps, as compared to dye or color retention exhibited by known hair care compositions.
The hair care compositions in accordance with the invention include shampoo and conditioner compositions. These compositions are typically applied to wetted hair and subsequently rinsed with water to remove at least a portion of the compositions from the hair. Shampoo compositions are typically employed for cleansing the hair. Conditioner compositions are typically employed to render hair more healthy and manageable. It is known to use these compositions separately or in combination. It is typical for a shampoo composition to be applied and rinsed, followed by the application and rinsing of a conditioner composition.
The hair care compositions according to the invention include a combination of a polymer component, a quinoa component and a silicone component. The polymer component includes a cationic terpolymer of vinylpyrrolidone, dimethylaminopropyl methacrylamide, and methacryloylaminopropyl lauryldimonium chloride.

In certain embodiments wherein the hair care composition is a conditioner, both first and second silicone compounds are preferably employed.
Further, it is understood that other silicone compounds known by one having ordinary skill in the art to exhibit properties similar to the silicone compounds described herein may be used in the compositions according to the invention.
The compositions are typically in the form of a liquid.
As previously described, the fading of oxidative color or dye in hair as a result of frequent shampoo washing is a common problem for manufacturers and consumers of hair care compositions formulated for color-treated hair. There are known physical and chemical factors that influence fading of artificial dye during the hair washing and rinsing processes. In particular, it is known that fading occurs primarily through hair dye solubility in water. That is, the artificial dye that is applied to hair, e.g., the hair shaft, can be faded and/or eroded as a result of washing and rinsing the hair. It is contemplated that polymers with hydrophobically-modified and cationic functionalities are effective in preventing hair dye dissolution in water. Without intending to be bound by any particular theory, it is believed that there is a synergistic effect of the polymer's hydrophobic moieties and cationic charges that are effective to protect hair dye during shampoo washing and rinsing processes. It has been found that the prevention of color fading is improved, e.g., there is a color protection benefit, when the compositions according to the invention are employed as compared to employing known hair care compositions formulated for color-treated hair. In particular, it has been found that hair care compositions including a combination of Polyquaternium-55, quinoa and the first silicone applied to color-treated hair during the washing and rinsing processes are effective to enhance color retention.
Further, there are various components and ingredients that are generally known in the art of hair care compositions that may be included in the shampoos and conditioners according to the invention. Suitable examples include, but are not limited to, fragrances, vitamins, pH adjusters (e.g., citric acid), gelling agents and surfactants. It is contemplated that one or more of these adjuvants may also be present in the compositions of the invention in conventional amounts.
A person skilled in the art will take care to select any optional additional additives and/or amount thereof such that the advantageous properties of the compositions according to the invention are not, or are not substantially, adversely affected by the addition. These substances may be selected variously by the person skilled in the art in order to prepare a composition which has the desired properties, for example, consistency or texture.
All of the ingredients for use in preparing the compositions in accordance with the invention can be combined in any order.
The following examples are illustrative only and are not intended to be interpreted as limiting the invention.
A shampoo in accordance with certain embodiments of the invention was prepared by conventional mixing of the ingredients identified in Table 1 in the specified amounts.
