[0031] BEST MODE FOR CARRYING OUT THE INVENTION

[0032] After diligent research, the inventors have surprisingly discovered that a process for treating keratin fibers, such as hair, and / or scalp, with an aqueous formulation comprising at least one hydrophilic active agent selected from C-glycoside compounds, a greater amount of water and a less amount of water-soluble alcohol as mediums, can impart the keratin fibers and / or scalp with an improved sensation of clean and light feelings, and exhibits an improved application sensation, and thereby completed the present invention.

[0033] Thus, the present invention relates to a process for treating keratin fibers, such as hair, and / or scalp, comprising a step of applying to the keratin fibers and / or scalp a composition comprising:

[0034] (a) at least one hydrophilic active agent selected from C-glycoside compounds;

[0035] (b) at least one water-soluble alcohol in an amount of less than 40% by weight relative to the total weight of the composition; and

[0036] (c) water in an amount of more than 10% by weight relative to the total weight of the composition.

[0037] Hereinafter, the process and the composition according to the present invention will be explained in a more detail.

[0038] [Process]

[0039] The process according to the present invention is for treating keratin fibers and / or scalp. Keratin fibers here means fibers containing keratin as a main constituent element, and examples thereof include hair, eyelash, eyebrow, and the like. Preferably, the keratin fiber in the present invention indicates hair. It is preferable that the process according to the present invention is for a cosmetic process for treating keratin fibers and / or scalp, and more preferably hair and / or scalp. The cosmetic process here can mean a non-therapeutic cosmetic process for caring for and / or conditioning keratin fibers and / or scalp.

[0040] The application step of the composition can be performed by any conventional means such as an applicator, e.g., hands, a spray, a brush, or a comb. The application step can be a topical application step.

[0041] The composition to be applied to the keratin fibers and / or scalp may take various forms, such as a solution, a gel, a lotion, a serum, a suspension, a dispersion, a fluid, a milk, a paste, a cream, a foam, an emulsion (O / W or W / O form), multiple (e.g., W / O / W, polyol / O / W, and O / W / O) emulsions, and the like. It is preferable that the composition according to the present invention be a solution, in particular a homogeneous solution. For the purposes of the present invention, the term “homogeneous” is intended to mean a composition consisting of a single phase.

[0042] The composition to be applied to the keratin fibers and / or scalp includes (a) at least one hydrophilic active agent selected from C-glycoside compounds, (b) at least one water-soluble alcohol in an amount of less than 40% by weight relative to the total weight of the composition, and (c) water in an amount of more than 10% by weight relative to the total weight of the composition.

[0043] Because the composition includes a relatively large amount of water and less amount of water- soluble alcohol with the specific hydrophilic active agent, the process according to the present invention can exhibit better application property with less squeakiness on keratin fibers, such as hair. This property can produce uniform and even coatings on the keratin fibers, such as hair. In addition, since the composition includes a relatively large amount of water and less amount of water-soluble alcohol, the process can impart the keratin fibers, such as hair, and / or scalp, with cleaner, lighter, watery, and fresh sensation.

[0044] The ingredients included in the composition will be described in detail below.

[0045] (Hydrophilic Active Agent)

[0046] The composition used in the process according to the present invention comprises (a) at least one hydrophilic active agent selected from C-glycoside compounds.

[0290] - Additional Previous Step

[0291] The process according to the present invention may comprise an optional step of cleaning the keratin fibers, such as hair, and / or scalp prior to the application of the composition. The cleaning step may be performed by, for example, shampooing the keratin fibers, followed by rinsing off the keratin fibers. The cleansing step is preferably carried out once before the process of the present invention is carried out. After rinsing off, the keratin fibers and / or scalp may be dried. The methods for drying the keratin fibers and / or scalp are not particularly limited, and may include drying with a towel and blowing-drying with a hair dryer.

[0292] When the process according to the present invention includes the step of cleaning the keratin fibers and / or scalp prior to the application of the composition, the keratin fibers and / or scalp may be wet or dried, preferably wet, just before the step of applying the composition to the keratin fibers and / or scalp is conducted.

[0293] - Additional Post Step

[0294] The process according to the present invention may or may not comprise a step of rinsing the applied composition off from the keratin fibers and / or scalp after the application step. Since the composition used in the process according to the present invention is preferably intended to be used as a leave-on (or leave-in) type cosmetic composition, in order to enhance the cosmetic effect, the process preferably does not comprise a rinsing step of the applied composition from the keratin fibers and / or scalp just after the application step.

[0295] The present invention may comprise an additional post step of drying the keratin fibers and / or scalp. The methods for drying the keratin fibers and / or scalp are not particularly limited, and may include drying with a towel and blowing-drying with a hair dryer.

[0296] In one embodiment of the present invention, after the application of the composition, the keratin fibers and / or scalp may be left as they are for a certain amount of time; typically from 1 second to 30 minutes, preferably from 30 seconds to 20 minutes, and more preferably from 1 minute to 15 minutes, if necessary, in order to let the composition penetrate into the keratin fibers and / or scalp.

[0297] [Composition]

[0298] The present invention relates to a composition for treating keratin fibers, such as hair, and / or scalp, comprising:

[0299] (a) at least one hydrophilic active agent selected from C-glycoside compounds,

[0300] (b) at least one water-soluble alcohol in an amount of less than 40% by weight relative to the total weight of the composition, and

[0301] (c) water in an amount of more than 10% by weight relative to the total weight of the composition.

[0302] The composition according to the present invention can be a cosmetic composition. In a particular embodiment, the composition according to the present invention is intended for topical application, especially to keratin fibers, preferably hair, and / or scalp.

[0303] The composition used according to the present invention is preferably intended to be used as a leave-on (or leave-in) type cosmetic composition. The term “leave-on” means a composition that is not intended to be washed / rinsed out or removed immediately after application. A leave- on composition is different from a rinse-off type composition, which is intended to be rinsed off after being used on keratin fibers and / or scalp.

[0304] In one preferred embodiment of the present invention, the composition is for caring for and / or conditioning keratin fibers, preferably hair, and / or scalp.

[0305] The composition according to the present invention may take various forms, such as a solution, a gel, a lotion, a serum, a suspension, a dispersion, a fluid, a milk, a paste, a cream, a foam, an emulsion (O / W or W / O form), multiple (e.g., W / O / W, polyol / O / W, and O / W / O) emulsions, and the like. It is preferable that the composition according to the present invention be a solution, in particular a homogeneous solution. For the purposes of the present invention, the term “homogeneous” is intended to mean a composition consisting of a single phase.

[0306] The ingredients (a) to (c) in the composition are the same as those explained in the process according to the present invention above. In addition, the composition according to the present invention can include other optional ingredients those explained in the process according to the present invention above. Also, the composition according to the present invention can be prepared as explained in the process according to the present invention above.

[0307] EXAMPLES

[0308] The present invention will be described in more detail by way of examples which however should not be construed as limiting the scope of the present invention.

[0309] [Processes according to Examples 1 and 2 and Comparative Examples 1 and 2]

[0310] The process according to Examples 1 and 2 and Comparative Examples 1 and 2 were conducted by the following protocol.

[0311] Three hair swatches (1 g, 27 cm) were prepared for each experiment. Each of the hair swatches was washed with Plain Shampoo shown in Table 1. After shampooing, the hair swatch was rinsed with water and then towel-dried. 0.20 g of each of the compositions shown in Table 2 were applied onto each hair swatch and left for 5 minutes, followed by blow-drying.

[0312] Each of the compositions used in the processes according to Examples 1 and 2 (Ex. 1 and 2) and Comparative Examples 1 and 2 (Comp. Ex. 1 and 2) was prepared by mixing the ingredients listed in the following Table 2. The numerical values for the amounts of the ingredients shown in Table 1 are all based on “% by weight” as raw materials, relative to the total weight of the composition. The hydroxypropyl tetrahydropyrantriol product of MEXORYL SCN® was obtained from NOVEAL.

[0313] [Evaluation]

[0314] (Sensory Assessments)

[0315] Sensory assessments were conducted with respect to "squeakiness during application" of each of the composition, "coating lightness / clean feel" and "coating uniformity" on the dried hair swatches by five experts under the following criteria with a five-level scale (very bad, bad, fair, good, and very good).

[0316] The scores thus obtained were averaged. The results are shown in following Table 2. Table 1. Composition of the plain shampoo.

[0317] Table 2

[0318] As can be seen from the results shown in Table 2, the process according to Examples 1 and 2, which used the composition comprising at least one hydrophilic active agent selected from C- glycoside compounds (Hydroxypropyl Tetrahydropyrantriol) and a specific amount of the water- soluble alcohol and water, exhibited an improved sensation during the application on the hair, and was able to provide the hair with better sensation after coating, such as improved coating lightness and a clean feel as well as improved coating uniformity.

[0319] In contrast, the process according to Comparative Examples 1 and 2, which did not use compositions comprising the specific amount of the water-soluble alcohol and water, caused more squeaky feelings during the application on the hair, and the sensory aspect of the hair after the coating was not very good with respect to coating lightness and clean a feel as well as coating uniformity compared to the process according to the invention.

[0320] Accordingly, it can be concluded that the process according to the present invention is very preferable for caring for and / or conditioning keratin fibers, in particular the hair, and / or the scalp.
