Hair treatment composition

Technical Field

The present invention relates to a method for improving the drying time of hair after moisture, e.g. bathing, shampooing, swimming, etc. In a preferred embodiment, the present invention relates to hair styling compositions applied to damp hair as a leave-on treatment to the hair, additionally reducing the time to dry the hair during the hair styling process.

Background

A common complaint among women, particularly long-haired women, is that it takes too long to dry and style their hair. In addition, hair is often damaged by prolonged exposure to the heat of a hair dryer. One proposed solution to these problems is described in U.S. patent No. 5,567,428, which discloses a composition containing (a) a silicone-grafted adhesive polymer, (b) a volatile, water-insoluble solvent for the polymer, and (c) a non-volatile drying aid for the polymer that is soluble in the solvent, which can form a film on the hair.

Paul Mitchell's Super Skinny claims to reduce hair drying time by penetrating deeply into the hair shaft, which allows drainage of water and allows the hair to shrink to a tighter diameter, thus helping to reduce drying time. The tighter diameter is said to enhance the surface area per volume and thus the rate of evaporation of water to reduce drying time.

Object of the Invention

The object of the present invention is to provide a method for improving hair drying after showering, bathing, swimming, shampooing, etc., by changing the hydrophobicity of the hair shaft to cause hair dewetting.

It is another object of the present invention to provide novel hair treatment compositions which reduce the drying time of the hair, which compositions contain a wetting agent to cause dewetting and sheeting of water from the hair, without the wetting agent sticking to the hair.

It is a further object to provide a hair treatment composition that reduces the time to dry wet hair and to style the hair.

It is a further object of the present invention to provide hair treatment compositions which reduce the time to dry wet hair and condition the hair.

It is a further object of the present invention to reduce damage to the hair by reducing the time to dry the hair.

It is a further object to improve hair suppleness and manageability by maintaining the hair in a partially hydrated condition.

These and other objects and advantages of the present invention will become apparent from the following detailed description.

Summary of The Invention

The compositions of the present invention are aqueous or hydroalcoholic hair treatment compositions comprising at least one wetting agent. The presence of the wetting agent imparts hydrophobicity to the hair when it is to be applied to wet hair. As a result, water present on the hair tends to bead up and be more easily removed, such as by gravity, by towel rubbing, by brushing, or by combing. Applicants have further found that the time to dry the hair is reduced, whether by airing, towel drying or blow drying. Suitable wetting agents may be selected from silicone polyether surfactants, fluoropolymers, fluorosurfactants, gemini surfactants, and combinations thereof.

In another aspect of the invention, the composition of the invention is a hair styling composition applied to wet hair, for example, to hair that has been partially dried by air drying, towel drying or blow drying. Wet hair to which a styling composition comprising at least one wetting agent has been applied dries more easily and is found to set more easily and faster.

In another embodiment, the composition of the present invention is an aqueous or hydroalcoholic hair treatment composition comprising: (a) at least one wetting agent; (b) at least one hair treatment ingredient; (c) water, and optionally (d) at least one volatile solvent.

The hair treatment composition may contain about 10 to 99% by weight of water, 0.05 to 10% by weight of a wetting agent; 0.01 to 10% by weight of a hair treatment ingredient selected from hair styling agents, hair conditioning agents and mixtures thereof, and 0 to 55% by weight of a volatile solvent. The hair treatment composition may be in the form of a gel, a mousse as an aerosol or pump, a cream, a spray as an aerosol or pump, a spray wax, a pomade, a hair liquid, a pomade, a stick, a solution, a dispersion or an emulsion. The products are leave-on products for application to wet hair, any product that can be used to treat hair, for example, styling products and fixative products; products that provide shine to the hair, or products that condition the hair to make it easier to handle.

Detailed Description

It was determined that the compositions of the present invention are applied to wet hair, particularly human hair on the head of a user, as a leave-on product. Wet hair includes hair such as damp hair, for example, hair that has been dried to remove some or all of the surface moisture from the hair shaft, but remains substantially hydrated, i.e., moisture has penetrated the hair shaft and remains in the hair shaft. The composition is formulated so as to reduce the time required for subsequent drying of the hair. For this purpose, the composition contains a wetting agent. When applied to wet hair, wetting agents reduce the surface tension of the hair and impart substantial hydrophobicity to the hair. This increased hydrophobicity causes the moisture present on the hair to bead up on the hair and also causes water droplets to drip from the hair, which can be attributed to gravity or other forces, such as combing, brushing, or air forces from a hair dryer. This process is referred to as sheeting. By removing excess moisture, hair treated with a wetting agent will dry more easily, i.e., in less time, whether it be air dried, towel dried, or air blower dried. In particular, the compositions and methods of the present invention are particularly suitable for hair longer than about three inches, and especially longer than about six inches.

While not wishing to be bound by any theory or mechanism of action, it is also believed that the wetting agent, especially in cooperation with the hair styling agent, provides a film on the hair such that some of the water that penetrates into the hair cuticle is retained within the hair shaft. This additionally reduces the amount of moisture to be removed from the hair and thus reduces the drying time. In addition, residual moisture in the hair (i.e., hydrated hair) will impart greater suppleness and manageability to the hair and reduce split ends. Reducing the time to dry the hair by blow drying also results in reduced damage to the hair.

In one aspect of the invention, there is provided a method of reducing the time to dry wet hair, for example, after drying a shower, shampooing, bathing, swimming, etc., the method comprising applying an aqueous or hydroalcoholic composition containing a wetting agent to the wet hair and subsequently drying the hair. The hair may be mechanically treated to aid in the formation of a thin layer of moisture on the hair prior to or during the drying step. Such treatments include brushing, combing, toweling, and the like. In the case of towel wiping, the mechanical action is generally seen in combination with the absorption of the moisture present on the hair. In the case of hair drying, it is seen that the force of the hot air from the dryer also causes the moisture to form a thin layer on the hair. In this embodiment, the composition includes a wetting agent in an aqueous or hydroalcoholic carrier. Surprisingly, the time to dry the hair is reduced, although additional water is also applied to the hair.

In another aspect of the invention, compositions and methods for styling hair are provided, while reducing the time to dry the hair. As previously mentioned, a method of reducing the time to dry wet hair, e.g., after drying a shower, shampooing, bathing, swimming, etc., comprises applying an aqueous or hydroalcoholic hair styling composition comprising a wetting agent, a styling ingredient, water, and optionally a volatile solvent, to the wet hair and then drying the hair. The hair may be mechanically treated to aid in the formation of a thin layer of moisture on the hair prior to or during the drying step. Such treatments include brushing, combing, toweling, and the like. In the case of towel wiping, the mechanical action is usually seen in combination with the absorption of the moisture present on the hair. In this embodiment, the composition includes a wetting agent in an aqueous or hydroalcoholic carrier. Surprisingly, the time to dry the hair is reduced, although other moisture present in the composition is also applied to the hair.

In another aspect of the invention, the compositions of the present invention are hair styling compositions that are applied to wet hair, for example by air drying, towel drying or blow drying partially dried hair. Wet hair to which a styling composition comprising at least one wetting agent has been applied dries more easily and is found to set more easily and more quickly. Such compositions are characterized by containing, in addition to a humectant, one or more hair treatment agents for assisting in hair styling.

All concentrations in the specification and claims are in weight percent of the total composition based on the active ingredient, unless otherwise indicated.

Wetting agent

The wetting agents used in the compositions of the present invention are characterized by their ability to reduce the surface tension of the hair. Thus, wetting agents typically have a surface tension of about 15 to about 26 dynes/cm (mN/m), and preferably about 17 to about 23 dynes/cm (mN/m). The surface tension of the wetting agent is the equilibrium surface tension at 25 ℃, which is independent of the concentration above the critical micelle formation concentration (CMC). Equilibrium surface tension is measured, for example, by the Wilhemy plate, DuNouy ring or pendant drop shape analysis method. See www.kruss.info/techniques/surface _ tension _ e. html.

The wetting agent used in the composition of the present invention is further characterized as having a Draves wetting value of less than 100 seconds, preferably less than 30 seconds, and most preferably less than 20 seconds. Draves wetting values were determined according to ASTM D2281-68. In this test, 0.5g of wetting agent was added to one liter of tap water in a 1000ml beaker and mixed thoroughly. A45 cm (5g) Drave 40/2 cotton thread doubled to a length of about 22cm was taped with a wire loop having a 40g plumb attached to an "s" copper hook. The other section of the cotton thread is cut off by scissors. The plumb was then gently placed on the surface of the water and dropped into a beaker while measuring the time it took for the thin wire between the plumb and the metal hook to relax. The procedure was repeated with two additional cotton threads and the average of three tests was taken.

Further, in some cases, the wetting agent is a superwetting agent (wetting agent). The super wetting agent is defined by the ability of a 1% aqueous wetting agent solution to be distributed on a paraffin matrix without mechanical means. A time below 10 seconds, preferably below 8 seconds, is indicated as a super-wetting of the wetting agent. See Randal m.hill, surface Science Series, v.86(Marcell Dekker 1999).

When present in an effective amount, forms a thin film of wetting agent on the hair and causes the water to bead up on the hair and drain from the hair by gravity. It has been found that the compositions of the present invention containing a wetting agent, particularly a super wetting agent, reduces the time to dry hair by 15% or more, preferably 25% or more, most preferably 50% or more.

The wetting agent is typically present in the composition in an amount of about 0.05 to 10 wt%, preferably about 0.1 to 5 wt%, most preferably about 0.5 to 2 wt%. In the case of super wetting agents, the wetting agent content tends to approach the lower end of the range.
