Cosmetic composition for hair or scalp that enhances the volume of hair {Cosmetic Composition for Hair and Scalp for Enhancing Hair Volume}

The present invention relates to a cosmetic composition for hair or scalp that enhances the volume of hair, and more particularly, to a single hydrophobic composition that exhibits an effect of increasing hair volume by increasing the hydrophobicity of the hair shaft area close to the scalp among hair strands. It relates to a cosmetic composition for enhancing hair volume comprising a polymer as an active ingredient or a mixture of a hydrophobic polymer and a nonionic polymer as an active ingredient.

Hair is a thin and thin protein structure with an average thickness of about 0.07 mm, and can be roughly divided into a hair shaft protruding from the outside of the skin and a hair root from the inside of the skin. The scalp has a basic structure and physiological function similar to that of the skin, and hair follicles of the scalp are more complex than other areas and are characterized by more sebaceous glands. The root of the hair is the part inside the hair follicle, which is buried in the scalp and has a depth of about 2 to 4 mm. The lowest part of the hair root is swollen like a bead, and this part is called the hair bulb, and the thickness of the hair is determined by the size of this part.

When the cross section of the hair is enlarged, it is divided into three parts: the innermost part and the central part, the medulla, the cortex surrounding the medulla, and the outermost part, the cuticle. The epidermis covers the surface of the hair and is a place with strong chemical resistance surrounding the inside of the hair, and consists of three layers called Epicuticle, Exocuticle and Endocuticle from the outside. The cortex exists inside the epidermis and accounts for most of the hair (85-90%). Its main component is keratin protein, and it is composed of cortical cells and intercellular bonding materials. . The medulla exists in the center of the hair and has some melanin pigment particles, and there are many small and large pores in the medulla that contain air.

In general, hair is composed of a protein called keratin, and specifically, hair is a keratin protein containing 14 to 18% of cystine among 18 amino acids. These keratin proteins are a type of protein that is very strong under mild conditions such as water or neutral solvents, but can be easily damaged by excessive physical and chemical treatments such as combing, heat drying, dyeing, and perm. Recently, as hair is damaged by various physical, chemical or environmental factors such as frequent perms and dyeing, the hair becomes rough and loses luster, and the softness and flexibility effect decreases, and friction increases, making it difficult to care for the hair. In addition to problems such as split ends, hair becomes thinner and loses elasticity, resulting in lifelessness and sagging, resulting in loss of volume.

The volume of hair is determined by the total area of the entire hair consisting of one or more strands covering (occupying) the skin. For example, if there are two people with similar hairstyles and hairstyles, and one person's hair is long and the other person's hair is short, the person with long hair prefers short hair due to the larger area of the hair. It can be said that the sense of volume of the hair is greater than the person who has it (the degree of hair volume is high). In addition, the spacing of the hair strands constituting the hair bundle (Hair Bundle, or Hair Tress), especially between the hair strands of the hair shaft at the end of the hair (hair tip) compared to the hair shaft (hair stem, hair stem) close to the hair root. The larger the spacing, the higher the volume of the hair. That is, people who have a large area of the entire hair on the skin and a large spacing between the hair strands of the hair bundle are generally recognized as having fuller hair due to the increased volume of the hair.

The thickness of the hair fiber is due to aging of the skin, especially aging of the skin or hair due to exposure to ultraviolet rays outdoors, or chemical/physical damage due to deficiency of components constituting the hair fiber and/or deformation of the hair fiber structure. Thinning, and the strength of the hair fiber also weakens, so the hair volume tends to decrease.

In particular, even for people with similar hair shapes and hairstyles, the volume of hair may vary depending on the thickness and strength of the hair fibers. The force to support the rest of the hair down to the tip of the hair shaft will be reduced. As a result, the 'sagging' phenomenon occurs in the entire hair, and in a sensual sense, it gives a cosmetically negative feeling such as "the volume looks reduced", "the hair looks weak", "the hair looks old", etc. Hair care, such as styling, can also be difficult.

In order to maintain and increase hair volume, it is important to improve hair elasticity. In particular, by enhancing hair elasticity through strengthening of hair roots (hair roots), it is possible to give an effect of exerting energy to the entire hair style.

Hair can absorb liquid/gaseous water up to 40% of the weight of hair, and the moisture content of hair is greatly affected by the surrounding environment. For example, it is known that the moisture content of hair increases when exposed to an environment in which a high temperature condition persists, an environment in which pH changes significantly, and an environment in which hydrogen bonds of hair are broken due to hair damage.

Changes in hair hydration are known to affect fiber elasticity. For example, it is known that when the moisture content of hair increases by 15 to 10%, the diameter of the hair strand increases by about 0.5 to 1% (Maria et al. , Brazilian jr of pharm. , Vol45, n.1, 2009 ).

In particular, the chemical characteristics of hair are different between the hair part adjacent to the scalp and the hair part far from the scalp. It exists in almost non-existent state (Bhushan et al. , Progress in Materials Science , 53:585-710, 2008).

On the other hand, hair or scalp cleaning compositions represented by shampoo usually have the function of cleaning hair and scalp, but recently, various products that have additional functions in addition to the original cleaning purpose have been released. Specifically, silicon By prescribing, products that prevent hair from flying after drying and improve softness, products for the purpose of arranging and repairing damaged hair by hair procedures such as dyeing or perm are being developed. However, existing products are advantageous in providing conditioning effects such as softness, moistness, flexibility, and ease of combing to the hair by using silicone, but in the case of hair with weak force such as thin hair or damaged hair, it rather sinks and hits the hair too much. There was a problem in giving the hair a sense of volume by losing it. In order to solve these problems, continuous research has been conducted on cosmetics for hair to improve the softness of hair during washing or after washing, and to restore and strengthen damaged hair. As a result, various methods have been tried, developed, and put into practical use to provide a strong and lasting hair conditioning effect.

According to the prior art, there is an example in which the formation of hair volume is cosmetically expressed and appealed through the prescription of a hair coating component in a cleaning/hair product, but it is clearly reported which prescription component causes the hair volume to be formed. there is no bar In addition, in the existing hair cosmetic composition, polyquaternium-11, polysilicon, polyurethane, etc. were used alone to give a sense of volume to the hair, but the actual volume enhancement effect was not satisfactory.

First, it is treated with BMAS-AP (Isododecane/Butyl Acrylate/Hydroxypropyl Dimethicone Acrylate Copolymer), which gives a sense of volume by varying the number of strands of the hair trasse, and then the point where the hair trasse starts to tilt at an angle of 45° By measuring the distance to the hair volume, it was confirmed whether the hair volume was increased or decreased, and the number of strands of the hair tracing, which was easy to evaluate the level of hair volume increase or decrease by a small amount of the test substance, was confirmed. The specific test method is as follows.

(1) A long hair trap composed of 5, 10, 20, 40, 80, and 100 hair strands by attaching about 1 cm of hair starting from the tip of the hair root to about 25 cm in length with instant adhesive. ([Option 1]: Of the hair shaft (hair stem) protruding out of the skin from the hair root, the hair part except for 4-6 cm (5 cm hair shaft) was bleached (with bleach (1 Agent: Treatment with 2 agents = 3: 1) for 30 minutes).By reducing the original volume of the hair trasse by bleaching treatment, the hair after the test substance treatment, in particular, the 4-6 cm hair part close to the hair root among the hair shafts of the hair [Option 2]: Dyeing treatment of the tip region of the hair tracing corresponding to the end of the hair shaft protruding out of the skin from the hair root. The hydrophilicity of the tip of the tresses increases, and the hydrophobicity of the hair part relatively close to the hair root increases, so the effect of the hydrophobic/hydrophilic properties of the hair part close to the hair root on the hair volume can be accurately evaluated. has exist).

(2) The test substance (control group: distilled water) was treated with an appropriate amount (e.g., 2 g) to the hair shaft area about 5 cm away from the tip of the hair root of the long hair tresses, and then rubbed and applied about 20 times (see FIG. 2).

(3) The hair shaft of the long-haired trasse coated with the test substance was washed with running water, completely dried (using a dryer), and left at room temperature (18 to 25 ° C) for about 30 minutes.

(4) After the step (3) is completed, the hair shaft is 4 to 6 cm from the end of the hair while the hair tracing is parallel to the horizontal plane Hair area) point (just outside the area where the adhesive exists) was fixed so that it could be read as O, the starting point.

(5) Let it naturally tilt toward the horizontal plane, but record the point (A) at an angle of 45 ° to the horizontal plane, and the length from the starting point 0, the point of the hair shaft, to the point (A) at an angle of 45 ° to the horizontal plane (O-A) ) was measured to confirm the number of strands of hair tracing suitable for hair volume evaluation.

As a result, as shown in Table 1 and FIG. 3, the O-A length of the hair tras treated with BMAS-AP was generally longer than that of the hair trasses treated with distilled water, and the change in hair volume was clearly visible to the naked eye. It was found that it could be confirmed, and in particular, when the number of hair strands was 100 to less than 150, the change in hair volume could be best confirmed.

For 7 types of raw materials among the test materials in Table 2 below, the level of increase or decrease in hair volume was evaluated by setting the number of hair strands in the hair tracing to 100.

[ reference example One]: hair tras Establishment of a method for evaluating hair volume and a method for screening substances that increase hair volume

Since the shape of a human head is a gentle oval shape, the slope of the hair growing out of the pore varies, except for the crown. For example, when a person is standing in an upright posture, the inclination (angle) formed between the skin surface of the crown and the hair (root area) is 90°, but the inclination (angle) formed between the skin surface of the side of the head or the skin surface of the back of the head and the hair (root area) is 0°. close. Therefore, in order to evaluate the hair volume using the hair trace, it is necessary to consider the slope formed by the scalp surface and the hair. The hair inclination needs to consider the influence of the position of the hair, the point where the inclination (bending) starts, and the length from the hair root to the point where the inclination starts. In addition, since hair volume is inevitably affected by the volume and weight of the entire hair, these factors also need to be considered.

[Evaluation method 1 of hair volume]: close to the scalp hair shaft Method for evaluating hair volume in the area

First, a method for evaluating hair volume in the hair shaft area close to the scalp was established.

1) Based on the results of Test Example 1, the number of hair strands was set to 100.

2) As a result of confirming the appropriate point for fixing the hair tracing, it is preferable to attach and fix the hair shaft at a position about 1cm away from the hair root among the hair shafts of the hair tracing so that it is perpendicular to the floor (horizontal plane). did

3) As a result of checking the tilt angle that can minimize the spreading effect caused by the volume and weight of the hair itself, it is desirable that the hair tracing form an angle of about 45° with the horizontal plane.

4) When the hair tracing is at an angle of about 45° with the horizontal plane, from the inner hair portion about 1 cm away from the tip of the hair root of the hair tracing, parallel to the horizontal plane with this inner hair portion as the reference point (1) Measure the length (RS1) to the inner hair part (reference point (2)) of the hair trace on the extension line in one direction,

5) Measure the length (RS2) from the reference point (2) of the hair trace to the outer hair part (reference point (3)) of the hair trace on the extension line perpendicular to the reference point (2) ,

6) Regarding hair volume, by calculating RS3 (= RS2 / RS1), it was possible to confirm a significant change in volume in the hair part of the hair shaft 4 to 6 cm close to the hair root (see FIG. 4).

[Evaluation method 2 of hair volume]: Volume evaluation method of the whole hair

A method for evaluating the volume of the entire hair was established.

1) In the same way as in the hair volume evaluation method 1, the number of hair strands was set to 100.

2) The hair tress was placed on a horizontal surface with the hair root facing upward.

3) A specific hair position (point) was defined.

R0: 0.5 to 1.5 cm, preferably 0.8 to 1.2 cm, more preferably 1 cm;

R1: 1.8 to 2.2 cm, preferably 1.9 to 2.1 cm, more preferably 2 cm away from R0;

R3: 2.5 to 3.5 cm, preferably 2.8 to 3.2 cm, more preferably 3 cm away from R0;

M6: 5.5 to 6.5 cm, preferably 5.8 to 6.2 cm, more preferably 6 cm from R0; and

M9: A point 8.5 to 9.5 cm away from R0, preferably 8.8 to 9.2 cm, more preferably 9 cm.

4) In order to represent the overall change in hair volume by the test substance, the following index values were calculated.

dR: value obtained by subtracting the diameter of the hair trace at the R1 point from the diameter of the hair trace at the R3 point; and

dM: value obtained by subtracting the diameter of the hair trace at the M6 point from the diameter of the hair trace at the M9 point.

Through the dR and dM values, it was possible to confirm a significant change in volume in the hair shaft area of 4 to 6 cm close to the hair root and in the hair area excluding it (see FIG. 5).

test example 2: Confirmation of hair volume increasing effect according to hair volume evaluation methods 1 and 2 according to the present invention

Based on the above hair volume evaluation methods 1 and 2, six raw materials (BMAS-AP, KSP-101, Styleze W-10, ADM 8301 E, BELSIL PF 200 and SC-200) among the test substances in Table 2 The level of increase and decrease in hair volume for the hair trace was evaluated and the sensory evaluation for the feeling of use was performed. Here, the hydrophobicity index used in evaluating the level of increase or decrease in hair volume is required until it is completely absorbed by dropping distilled water (approx. It is expressed by measuring the time (s) in seconds to be measured at the hair root and hair tip.

[ 1] Roughness: 0 points - no roughness, 5 points - very roughness; [2] Residual feeling: 0 points - no residual feeling, 5 points - strong residual feeling; [3] Coating feeling: 0 points - no coating feeling , 5 points - strong coating).

As a result, as shown in Table 4, BMAS-AP, KSP-101, Styleze W-10 and SC-200 are effective in improving hair volume based on the criteria of evaluation method 1 and evaluation method 2 described above. It was confirmed that it was appropriate, and a satisfactory level was obtained in terms of reduction in use.

Regarding Table 4, in the case of BMAS-AP, KSP-101, Styleze W-10, and SC-200 having an RS3 value of 1 or more according to Evaluation Method 1, the hair area of 4 to 6 cm close to the hair root was considered to have high volume. In the case of distilled water with an RS3 value of less than 1, ADM 8301 E, and BELSIL PF 200, it was confirmed that the hair part of 4 to 6 cm close to the hair root had low volume.

On the other hand, BMAS-AP, KSP-101, Styleze W-10, and SC-200 with a dR value of 10 or more according to evaluation method 2 showed a clear increase in volume in the hair area of 4 to 6 cm close to the hair root, and a dR value of 10 It was found that ADM 8301 E and BELSIL PF 200, which are less than the hair root, showed a great effect of increasing hair volume according to the hair part other than the 4-6cm hair part close to the hair root. These results were also consistent with the results in Table 3.

test example 3: Hair volume enhancement efficacy, stability and feeling of use evaluation

[ reference example 2]: Determination of Shampoo Base Composition

After applying the shampoo base candidate to the hair of 20 seniors aged 40 to 50 years old, a sensory evaluation on the feeling of use was performed on a 9-point scale (the evaluation score standard for the 9-point scale was '[1 point'). ]very low - [5 points] so-so - [9 points] confirmed as 'very high') (data not presented).

As shown in FIG. 6, as a result of the sensory evaluation according to the average score of 20 seniors, the shampoo was found to be excellent in 8 items (foam level, rinse degree, softness when rinsing, detergency, softness when drying, calmness, styling, volume) The base candidate was selected as a basic formulation (Comparative Example 1) for future experiments. Accordingly, shampoo compositions commonly containing the main components of the selected shampoo base were prepared as shown in Tables 5 to 8 below.

Specifically, isododeca/butyl acrylate/hydroxypropyl dimethicone acrylate copolymer (BMAS-AP), which is the hydrophobic polymer finally selected in the shampoo base and Test Examples 1 and 2, vinyl dimethicone/methicone seal A shampoo composition containing sesquioxane crosspolymer (KSP-101) and polyquaternium-55 (PQ-55; Styleze W-10) in different combinations is prepared, and the shampoo base, the hydrophobic polymer and the nonionic polymer Shampoo compositions containing phosphorus polyquaternium-11 (PQ-11) in different combinations were prepared and it was confirmed whether each composition had an effect of improving hair volume and feeling of use.

Polyquaternium-11 used in the present invention among the test substances in Table 2 and Tables 5 to 8 is a copolymer of vinylpyrrolidone and quaternized dimethylaminoethyl methacrylate, mainly vinylpyrrolidone and N,N- It is a 20% aqueous solution of a copolymer of diethyl sulfate of a copolymer of dimethylaminoethyl methacrylate.
