ABSTRACT:
The present invention is directed to compositions and methods for styling hair. More particularly, the hair styling compositions of the present invention comprise at least one adhesive particle optionally in a cosmetically acceptable carrier. The compositions of the present invention may have at least one adhesive particle present in an amount effective to provide a holding and/or reshapable effect.
Fixing the hairstyle is an important element in hair styling, and involves, for example, maintaining a shaping that has already been carried out, or simultaneously shaping and fixing of the hair.
In accordance with the invention, the term “hair styling composition” relates to any kind of composition that can be used to effect hair styling including, for example, fixing compositions, shampoos, conditioners, permanent waving compositions, hair care products, and hair treatment products.
There are countless products available to the consumer, which enable one to style his/her hair in a particular shape or configuration and result in the desired shape or configuration being retained. The holding or retention of the style is usually accomplished by the delivery of a composition containing a film former or an adhesive that remains on the hair after evaporation of some or all of the carrier. As used herein, the term “carrier” refers to any solvent or other cosmetically acceptable formulation that is useful in delivering a cosmetic agent as described below.
The most prevalent hair styling compositions on the cosmetic market for shaping and/or fixing the hairstyle are spray compositions comprising a carrier, usually alcohol- or water-based, and one or more materials, generally polymer resins. One of the functions of a polymer resin is to form links between the hairs, these materials also being called fixatives, in a mixture with various cosmetic adjuvants. This solution is generally packaged either in an appropriate aerosol container, which is pressurized with the aid of a propellant, or in a pump flask.
Other known hair styling compositions include styling gels and mousses, which are generally applied to the wetted hair before brushing or setting it. In contrast to the conventional aerosol lacquers, these compositions can have the disadvantage that they do not allow the hair to be fixed in a shape created before their application. In fact, these compositions are essentially aqueous and their application wets the hair, rendering it difficult to maintain the initial shape of the hairstyle. In order to shape and fix the hairstyle, therefore, it is necessary to carry out subsequent brushing and/or drying with these types of compositions.
One embodiment of the present invention provides a hair styling composition comprising, optionally in a cosmetically acceptable carrier, at least one adhesive particle, wherein the at least one adhesive particle comprises at least one substrate and an at least partial coating, wherein the at least partial coating comprises at least one adhesive.
The invention further provides for a method of providing a holding effect to the hair by applying to the hair a hair styling composition that comprises, optionally in a cosmetically acceptable carrier, at least one adhesive particle, wherein the at least one adhesive particle comprises at least one substrate and an at least partial coating, wherein the at least partial coating comprises at least one adhesive and wherein the at least one adhesive particle is present in an amount effective to provide a holding effect. The adhesive particle may retain its adhesive properties following evaporation of the cosmetically acceptable carrier.
As used herein, to provide a “holding effect” means to provide a hair styling that retains a desired shape or configuration until water, heat, time, and/or physical contact disrupt the means by which the desired shape or configuration had been retained.
While the hair styling compositions currently on the market are very effective in holding the hair in a desired shape or configuration, generally they are not designed to allow the hairstyle to be later modified to a desired shape, which is other than that formed initially, without reapplying a hair styling composition or heat. Moreover, under various kinds of stress, the hairstyle has a tendency to take on an undesirable permanent set, which cannot easily be modified. For example, as the carrier evaporates, bridging or welding points are formed between and among individual hair strands or groups of hair strands to maintain the desired shape. However, those bridges or weld points may be easily broken by brushing, combing or other mechanical means, such as running one's fingers through the hair. Once broken, the weld points of such compositions cannot be reset and the styling or hold formerly maintained by the weld point is lost. Typically, the user's only recourse for restyling and holding the hair in a newly or previously desired style or configuration is to reapply such a hair styling composition or heat. Unfortunately, in addition to being bothersome, several re-applications of most hair styling compositions result in hair with a rough feel and texture and a stiff and unnatural look.
In attempts to provide a hair styling composition that may be reworked, a composition that applies a flexible film has been used with the hope that it would allow rearrangement of hair without impairing the hair holding capability. See WO 99/00105. This hair styling composition utilizes specific organic adhesive polymers in association with ethoxylated alcohol surfactants and a carrier. The composition can be delivered in the form of a mousse. Similarly, U.S. Pat. No. 5,019,377 describes a flexible film composition for a temporary arrangement of the hair, which comprises the use of a low glass transition temperature adhesive copolymer. At least one of the monomers making up the adhesive copolymer is selected from acrylate amides and methacrylate amides and at least one other monomer is selected from acrylate esters and methacrylate esters.
While the compositions described above result in flexible films that are effective in holding the hair and can allow some reworking of the hair, they are not yet optimized. Specifically, where weld points holding the hair together form and can encompass many strands or clumps of hair, the hair cannot be reworked with ease. This can give an unnatural effect to the hair, such as a helmet appearance. Additionally, these weld points, as in previous hair styling compositions, are easily broken. Once the weld points are broken, the hair cannot be reworked. Consequently, one embodiment of the present invention relates to hair styling compositions that do not rely on such non-reworkable weld points to retain a shape or configuration of the hair and therefore enable a shape or configuration to be easily and repeatedly reworked without re-application of the hair styling composition or heat.
In another embodiment, the present invention provides a reshapable hair styling composition comprising, optionally in a cosmetically acceptable carrier, at least one adhesive particle, wherein the at least one adhesive particle comprises at least one substrate and an at least partial coating, wherein the at least partial coating comprises at least one adhesive and wherein the at least one adhesive particle is present in an amount effective to obtain a reshapable effect.
The invention further provides for a method of providing a reshapable effect to the hair by applying to the hair a reshapable hair styling composition that comprises, optionally in a cosmetically acceptable carrier, at least one adhesive particle, wherein the at least one adhesive particle comprises at least one substrate and an at least partial coating, wherein the at least partial coating comprises at least one adhesive and wherein the at least one adhesive particle is present in an amount effective to provide a reshapable effect. The adhesive particle may retain its adhesive properties following evaporation of the cosmetically acceptable carrier.
