Description

A hair or scalp cosmetic composition for increasing the volume of hair

The present invention relates to a hair or scalp cosmetic composition for enhancing the volume of hair, and more particularly, to a hair or scalp cosmetic composition which increases the hydrophobicity of a hair region adjacent to a scalp of a hair strand, The present invention relates to a cosmetic composition for enhancing the volume of hair containing 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. It can be roughly classified into a hair shaft that goes outside the skin and a hair root inside the skin. The scalp has a basic structure and physiological functions similar to the skin, and the hair follicle is more complex than the other parts and has many sebaceous glands. The hair follicle part is the part inside the hair follicle which is buried in the scalp and the depth is about 2 ~ 4mm. The bottom part of the root is bulge like a bead, and this part is called a hair bulb, and the thickness of the hair is determined by the size of this part.

The enlarged section of the hair is divided into three parts: Medulla, which is the innermost part and the center, Cortex, which surrounds the water quality, and Cuticle, which is the outer part of the hair. The skin coat covers the surface of the hair and has a strong chemical resistance surrounding the inside of hair. It consists of three layers from the outside called Epicuticle, Exocuticle and Endocuticle. The follicle is located in the inner part of the eye patch and occupies the majority (85 ~ 90%) of the hair. The main component is keratin protein and consists of cortical cells and intercellular binding material. . The quality of the water exists in the center of the hair, it has some melanin pigment particles, and the water contains air because it has many big and small fears.

In general, the hair is composed of a protein called keratin. Specifically, hair is a keratin protein containing 14 to 18% cystine among 18 kinds of amino acids. These keratin proteins are a very strong protein in mild conditions, such as water or neutral solvents, but can easily be damaged by excessive physicochemical treatments such as combing, dry heat, dyeing, perming, and the like. In recent years, due to various physical, chemical or environmental factors such as frequent perms, dyeing, etc., the hair is damaged, and the hair becomes rough and loses its gloss and the softness and softening effect are lowered. There is a problem that hair tends to become thin and elasticity is lost, and there is no volume feeling as it is struck.

The volume of hair is determined by the total area of the hair consisting of one or more strands covering (occupying) the skin. For example, if you have two people with similar hair styles and hairstyles, and one person has a long hair length and the other has a short hair length, a person with long hair may have hair that has a short hair length The volume of the hair is larger than that of the person having the hair (the volume of hair is high). It is also known that the distance between the hair strands constituting the hair bundle (Hair Bundle or Hair Tress), especially between the hair strands at the hairpin end (the end of the hair) The larger the gap, the higher the volume of the hair. That is, a person with a large area of hair on the skin and a large distance between the hair strands of hair bundles is generally recognized to have more abundant hair due to the volume increase of the hair.

The hair has a thickness of the hair fiber due to deficiency of the constituent of the hair fiber and / or deformation of the hair fiber structure due to aging of the skin, especially aging of skin or hair due to aging of the skin or chemical / And the strength of the hair fiber is also weakened, and the feeling of hair volume tends to decrease.

Particularly, even a person having a similar hair shape and hair style may have a different volume of hair depending on the thickness and strength of the hair fiber. For example, when the strength of the hair fiber is weakened, hair coming out from the scalp The force to support the rest of the hair to the end of the hairy area of the hair will be reduced. As a result, the hair becomes 'stuck' in the whole, and in sensual sense, it gives a negative feeling of cosmetics such as "the volume seems to decrease", "the power does not seem" Hair care such as styling may also be difficult.

In order to maintain and increase the volume of hair, it is important to improve the elasticity of the hair. In particular, by strengthening the hair roots (hair roots), the hair elasticity can be enhanced to give the effect to the whole hairstyle.

Hair can absorb liquid / gaseous water up to 40% of hair weight, and the moisture content of the hair is highly affected by the surrounding environment. For example, it is known that the moisture content of the hair increases when exposed to a high temperature state, an environment with a high pH change, and an environment in which the hydrogen bonding of the hair is broken due to hair damage.

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

Particularly, the chemical characteristic of the hair is that the hairs adjacent to the scalp and the hairs far away from the scalp are different, and the hair near the scalp is in a state of perfect cuticle, but the tip of the hair has a cuticle (Bhushan et al. , Progress in Materials Science , 53: 585-710, 2008).

On the other hand, hair or scalp cleansing compositions typified by shampoos generally have hair and scalp cleansing function. However, recently, various products having additional functions other than the original cleaning purpose have been introduced. Products that prevent the hair from falling off after drying the hair and improve the softness, and products for the purpose of arranging and repairing hair damaged by the hair treatment such as dyeing or polishing are being developed. However, the conventional products are advantageous for providing conditioning effects such as softness, moistness, flexibility, and combability by using silicone, but in the case of weak hair such as thin hair or damaged hair, There was a problem in giving a volume feeling to the hair. To solve these problems, there has been a continuous study on cosmetics for hair to improve the softness of hair after washing or washing and to restore and strengthen damaged hair. As a result, various methods have been tried and developed and put into practical use in order to give a strong and continuous effect of hair conditioning.

According to the prior art, there is an example of cosmetic expression and desirability of formation of hair volume through the formulation of a hair coating component in a cleaning / wool product, but specifically, it is clearly reported in which prescription component the hair volume is formed There is no bar. In addition, in the conventional hair cosmetic compositions, polyquaternium-11, polysilicon, polyurethane and the like were used singly to impart a volume feeling to hair, but the volume enhancing effect was not satisfactory.

Under these technical backgrounds, the present inventors have made extensive efforts to develop a composition for external application for hair that improves hair condition such as hair volume. As a result, it has been found that a composition containing the hydrophobic polymer alone as an active ingredient or a mixture of a hydrophobic polymer and a non- , Hydrophobic polymers composed of isododeca / butyl acrylate / hiacyclopropyldimethicone acrylate copolymer, vinyl dimethicone / methicone silsesquioxane crosspolymer and polyquaternium-55, and nonionic polymer The use of a cosmetic composition for increasing the volume of hair containing a mixture of polyquaternium-11 as an active ingredient improves hair volume formation (hair volume, hair volume, etc.) as compared with a cosmetic composition for general hair application (e.g., shampoo, , The cushioning feeling of the hair located in the crown of the head becomes enriched, The effect of improving the residual feeling of hair on the composition and improving the feeling of finishing coating of the hair was confirmed, and the present invention was completed.

An object of the present invention is to provide a cosmetic composition for increasing the volume of hair.

The present invention also provides the use of a single hydrophobic polymer or a mixture of a hydrophobic polymer and a nonionic polymer, particularly as a hair volume enhancer, in the production of cosmetic compositions or cosmetics for increasing the volume of hair.

The use of the cosmetic composition for enhancing the volume of hair according to the present invention can improve hair volume formation (enhance hair volume) as compared with a cosmetic composition for general hair application (e.g., shampoo, rinse, etc.) The feeling of cushion of the hair becomes enriched, the feeling of residual hair on the cosmetic composition is improved, and the feeling of finishing coating of the hair is improved.

Test Example  One: Of the hair by a small amount of the test substance Volume  Identification of number of hair strands in hair traces suitable for evaluation of improvement efficacy

In general hair tress which is used in hair formulations, there is a lot of raw materials used in the evaluation of formulations due to a large number of hair strands, and it is difficult to evaluate the hair volume between hair traces. Therefore, Hair traces suitable for evaluating the improvement of the volume power were prepared.

First, treatment with BMAS-AP (Isododecane / Butyl Acrylate / Hydroxypropyl Dimethicone Acrylate Copolymer), which imparts a sense of volume by varying the number of strands of hair traces, is performed at a point where hair torsion begins to tilt at an angle of 45 °, , And the number of hair traces which can be easily evaluated in the level of hair volume increase by a small amount of test material was confirmed by checking whether the hair volume was increased or decreased. Specific test methods are as follows.

(1) A black hair having a length of about 25 cm was attached to an area of about 1 cm of hair starting from the end of the hair follicle with an instant adhesive to form a hair follicle consisting of 5, 10, 20, 40, (Option 1): The hair was removed from the hair except 4 ~ 6cm (5cm hairy area) of the hair shaft protruding out from the hair root (hair root, hair stem) By reducing the volume feeling of the hair traces by decolorizing treatment, the hair after treatment of the test material, especially the hair region of 4 to 6 cm close to the hair follicle, [Option 2]: Dyeing the tip region of the hair traces corresponding to the end of the hairy part protruding from the hair follicle, The tip of the trace has high hydrophilicity And relatively close to that in the hair follicle is part hydrophobic (Hydrophobicity), this plastic can / hydrophilic nature of the area close to the hair follicle to accurately assess the impact of the hair volume increases).

(2) The test substance (control: distilled water) was treated with an appropriate amount (for example, 2 g) and then rubbed about 20 times (see Fig. 2).

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

(4) After the completion of the above step (3), the hair traces are parallel to the horizontal plane, and the hairy part of 4 ~ 6cm from the hair edge (4 ~ 6cm near the hair follicle, Hair area) point (just outside the area where the adhesive is present) was fixed to be read as O which is the starting point.

(5) Naturally record a point (A) at an angle of 45 ° to the horizontal plane so that it is inclined in the horizontal direction, and the length from the starting point (0), which is the point of the morning point to the point (A) ) Were measured to confirm the number of strands of hair strain suitable for hair volume evaluation.

As a result, as shown in Table 1 and Fig. 3, OA length of the hair strain treated with BMAS-AP was generally longer than that of the hair strain treated with distilled water, and the change in hair volume was visually evident Especially when the number of hair strands was less than 100 to 150, the change of hair volume was most confirmed.

For seven raw materials of the test materials shown in the following Table 2, the number of hair strands in the hair strain was 100, and the level of increase and decrease of the hair volume was evaluated.

[ Reference example  One]: Hair Trace  Establishment of evaluation method of hair volume used and screening method of material to increase volume of hair

Since the shape of the head of a person is a gentle oval shape, the slope of the hair that grows in the pores except for the crown part varies. For example, when a person is standing on a regular basis, the inclination angle (angle) between the parietal skin surface and hair (root portion) is 90 °, while the slope between the side surface of the skin on the side of the back or back hair and hair (root portion) close. Therefore, in order to evaluate the hair volume using the hair strain, it is necessary to consider the inclination of the scalp surface and the hair. It is necessary to consider the influence of the length of the hair from the position of the hair, the point where the inclination starts, and the point from the hair root to the point where the bending starts. In addition, since the volume of hair 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]: How to evaluate the volume of hair on the scalp and adjacent hair

First, we established a hair volume evaluation method for the scalp near the scalp.

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

2) As a result of checking the appropriate points for fixing the hair traces, it is desirable to fix the hair area at a position about 1 cm away from the hair roots of the hair traces of the hair traces by attaching them to the flat plate at right angles to the bottom surface Respectively.

3) As a result of checking the tilting angle that minimizes the spreading effect by the volume and weight of the hair itself, it is preferable that the hair tilting angle be approximately 45 ° with the horizontal plane.

4) When the hair strain is at an angle of about 45 ° with the horizontal plane, the inner hair part is separated from the inner hair part about 1 cm away from the hair follicle end part and is parallel to the horizontal plane as the reference point (1) The length RS1 from the inner hair portion (reference point 2) of the hair traces on the extension line in one direction is measured,

5) The length (RS2) from the reference point 2 to the outer hair portion (reference point 3) of the hair traces extending in the direction perpendicular to the reference point 2 is measured for the hair traces ,

6) By calculating the hair volume, RS3 (= RS2 / RS1), it was possible to confirm the volume change of 4 to 6 cm of hair close to hair root in the hairy region (see FIG. 4).

[Evaluation method 2 of hair volume]: How to evaluate the volume of whole hair

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

1) Evaluation of hair volume In the same manner as in Method 1, the number of hair strands was set to 100.

2) Hair traces were placed on a horizontal plane with the hair follicles pointing upwards.

3) We defined a specific hair position (point).

R0: the length from the root end of the hair shaft to the point where the hair stem (herring region) starts, 0.5 to 1.5 cm, preferably 0.8 to 1.2 cm, more preferably 1 cm;

R1: a point 1.8 to 2.2 cm, preferably 1.9 to 2.1 cm, more preferably 2 cm from the above-mentioned R0;

R3: 2.5 to 3.5 cm, preferably 2.8 to 3.2 cm, more preferably 3 cm from the above-mentioned R0;

M6: a point 5.5 to 6.5 cm, preferably 5.8 to 6.2 cm, more preferably 6 cm away from the above-mentioned R0; And

M9: 8.5 to 9.5 cm, preferably 8.8 to 9.2 cm, more preferably 9 cm from the above-mentioned R0.

4) The following exponent values were calculated to show the overall change in hair volume by the test material.

dR: the diameter of the hair traces at the R3 point minus the diameter of the hair trail at the R1 point; And

dM: the diameter of the hair traces at the M9 point minus the diameter of the hair traces at the M6 point.

With the dR and dM values, it was possible to confirm the volume change of 4 ~ 6cm hair parts close to the hair follicle of the hairy part and the hair parts except this hair part (see FIG. 5).

Test Example  2: Confirmation of hair volume increase effect according to the hair volume evaluation methods 1 and 2 according to the present invention

(BMAS-AP, KSP-101, Styleze W-10, ADM 8301 E, BELSIL PF 200 and SC-200) among the test materials shown in Table 2 on the basis of the above hair volume evaluation methods 1 and 2 Evaluation of the level of increase and decrease of hair volume for hair traces and sensory evaluation of feelings were performed. Here, the hydrophobicity index used in the evaluation of the increase / decrease level of the hair volume is determined by dropping distilled water (about 50 μl) using a pipette on the hair traces treated (and washed) with each raw material The time (s) in seconds is measured in the hair root and hair tip.

Sensory evaluation of sensation of feeling on the hair strain was evaluated by roughness, residual feeling and coating feeling based on the sensory score of a specialized panel, and each numerical value was evaluated by a score of 5 points scale ([ 1] roughness: 0 point - no rough feeling, 5 point - very rough feeling [2] residual feeling: 0 point - no residual feeling, 5 point - strong residual feeling [3] coating feeling: , 5 points - strong coating feeling).

As a result, as shown in Table 4, BMAS-AP, KSP-101, Styleze W-10 and SC-200 had the effect of improving the hair volume based on the criteria of the above- We confirmed that it was appropriate and got a satisfactory level of use reduction.

With respect to 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 the evaluation method 1, hair portions of 4-6 cm close to the hair roots are high in volume In the case of distilled water with an RS3 value of less than 1, ADM 8301 E and BELSIL PF 200, it was found that the hair volume of 4-6 cm adjacent to the root was lower in volume.

On the other hand, in BMAS-AP, KSP-101, Styleze W-10 and SC-200 with dR value of 10 or more according to the evaluation method 2, the volume of hair of 4 to 6 cm near the hair follicle was markedly increased. , The ADM 8301 E and BELSIL PF 200 showed a large effect of increasing the volume of the hair depending on the portion of the hair other than the hair region of 4 to 6 cm close to the hair follicle. These results are consistent with the results in Table 3.

Test Example  3: Evaluation of hair volume enhancement efficacy, stability, and feel of a shampoo composition containing a substance that increases the volume of hair

[Reference Example 2] Determination of Shampoo Base Composition

The shampoo base candidates were applied to the hair of 20 senior seniors aged 40 to 50 years, and sensory evaluation was performed on the sensation using a 9-point scale (the score on the 9-point scale was [1 point ] Very low - [5 points] Just so - [9 points] Very high (confirmed) (no data).

As shown in Fig. 6, the sensory evaluation results according to the average score of the senior 20 people showed that the shampoo excellent in eight items (degree of bubble, degree of rinsing, softness in rinsing, smoothness in drying, calmness, styling, Base candidates were selected as the basic formulation for further experiments (Comparative Example 1). Accordingly, a shampoo composition containing common components of the selected shampoo bases was prepared as shown in Tables 5 to 8 below.
