ABSTRACT:
FIELD OF THE INVENTION
The present invention is directed to hair care compositions. In particular, the present invention is directed to hair care compositions which include polyalkylene glycol styling agents and which exhibit an advantageous combination of improved hair restyling performance and improved hair look and feel without reapplication of the composition and/or application of additional hair care aids.
BACKGROUND OF THE INVENTION
Hair styling compositions are well known and are commercially available in a variety of forms including mousses, gels, lotions, pumps, or hair sprays. Many of these products contain various hair styling agents to provide temporary hair styling benefits such as body, hold, luster, improved hair feel, and good style retention.
One method of providing temporary hair styling benefits from a styling product involves the use of a hair gel. Many hair gel products have been formulated such that the hair gel composition can be applied to wet or damp hair before styling or “setting” the hair. Typically, the hair gel compositions are aqueous formulations which contain water-soluble styling agents that provide adhesive properties to the hair while the hair is wet and being styled. These styling agents, however, can form hard breakable films on the hair as the styling process nears completion, and this can result in an unacceptable hair style or in a hair style that cannot be restyled unless additional water and/or supplemental styling products are added to the hair. Moreover, the use of aqueous hair gel compositions which contain water-soluble styling agents can leave the hair feeling unduly sticky and stiff.
Various other aqueous hair gel compositions have been employed in attempts to improve hair styling performance and hair feel. Oftentimes, however, these hair gel compositions are applied to wet or damp hair to achieve the desired hair conditioning benefits and generally require reapplication of the composition or application of another styling product to maintain or modify the original hairstyle.
A recent method of making a hair styling composition that can be applied to wet and/or dry hair during the styling process is described in JP 8-346608, published Jun. 23, 1998. The hair styling compositions disclosed in this publication contain polyalkylene glyceryl ether styling agents to provide for sustained hair styling performance and aesthetics such as luster to the hair. These polyalkylene glyceryl ether styling agents typically do not readily penetrate into the hair and can remain on the hair fibers to provide hair styling benefits. The polyalkylene glyceryl ether-containing compositions disclosed in this particular publication, however, tend to provide minimal or no hold to the hair, and this can result in poor style achievement and poor style retention performance.
Another hair styling composition that can be applied during the styling process is described in WO 98/38969, published Sep. 11, 1998. The compositions disclosed in this publication use certain styling agents which deliver hair style performance to dry hair, and provide for the dry hair to be restyled without having to reapply the composition and without requiring the use of another styling product. The styling agents described in this reference include anionic, cationic, amphoteric, and nonionic styling polymers, preferably sulfonated anionic styling polymers which have an average molecular weight of from about 500 to about 5,000,000. These styling agents, however, have exceptional cohesive strength which provides for the hair fibers to be firmly held together, and this can cause the dry hair to feel coarse and to be difficult to comb, style and restyle.
Recently, it has become known to utilize hair styling compositions containing polyalkylene glycol styling agents. These hair styling compositions are described in U.S. application Ser. No. 09/305,502 and are advantageous in that they provide for improved dry hair restyling performance without the need to reapply the composition and/or apply additional styling aids.
In order to provide such compositions with further improved performance, it would be advantageous to improve the styling strength delivered by the polyalkylene glycol styling agents, without having to increase to level of the polyalkylene glycol styling agents in the compositions.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide improved hair care compositions. It is a more specific object of the invention to provide hair care compositions which provide desirable wet and/or dry hair restyling performance. It is a further object of the invention to provide such compositions which also provide good hair look and feel. It is yet another object of the present invention to provide compositions which provide desirable wet and/or dry hair restyling performance and good hair look and feel for extended periods of time without the need to reapply the composition or apply any other styling aids. It is a further object of the present invention to provide leave-on hair styling compositions which do not feel unduly sticky or stiff after the composition has been applied and allowed to dry on the hair.
These and additional objects and advantages are provided by the present invention. In a first embodiment, the present invention is directed to hair care compositions which comprise (a) a water-soluble polyalkylene glycol having a number average molecular weight of from about 200 to about 900 and from about 4 to about 18 repeating alkylene oxide radicals, wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; (b) a film forming polymer, wherein the film forming polymer is soluble in the polyalkylene glycol and wherein the weight ratio of the polyalkylene glycol to the film forming polymer ranges from about 5:1 to about 50:1; and (c) a liquid carrier.
Another embodiment of the present invention is directed to hair care compositions which comprise (a) from about 5% to about 20% by weight of a water-soluble polyalkylene glycol having a number average molecular weight of from about 200 to about 900 and from about 4 to about 18 repeating alkylene oxide radicals, wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; (b) a film forming polymer, wherein the film forming polymer is soluble in the polyalkylene glycol and wherein the weight ratio of the polyalkylene glycol to the film forming polymer ranges from about 10:1 to about 40:1; and (c) a liquid carrier.
The present invention is also directed to hair care compositions which comprise (a) from about 5% to about 12%, by weight, of a water-soluble polyalkylene glycol having a number average molecular weight of from about 200 to about 900 and from about 4 to about 18 repeating alkylene oxide radicals, wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; (b) from about 0.25% to about 1.5%, by weight, of a film forming polymer, wherein the film forming polymer is soluble in the polyalkylene glycol and wherein the weight ratio of the polyalkylene glycol to the film forming polymer ranges from about 10:1 to about 40:1; and (c) from about 85% to about 95%, by weight, of a liquid carrier.
Yet another embodiment of the present invention is directed to hair care hair care compositions which comprise (a) from about 5% to about 12%, by weight, of a water-soluble polyalkylene glycol having a number average molecular weight of from about 200 to about 900 and from about 4 to about 18 repeating alkylene oxide radicals, wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; (b) from about 0.25% to about 1.5%, by weight, of a film forming polymer, wherein the film forming polymer is soluble in the polyalkylene glycol and wherein the weight ratio of the polyalkylene glycol to the film forming polymer ranges from about 5:1 to about 50:1; (c) from about 85% to about 95%, by weight, of a liquid carrier; and (d) from about 1% to about 5%, by weight, of a non-volatile silicone with a molecular weight greater than abou
