Description

[0001] The present invention relates to a hair styling composition containing a new wax polymer,

The present invention relates to a styling agent composition, and more particularly, to a styling agent composition which contains a novel wax polymer and enables re-styling in a polymer resin type styling agent such as a spray, a mousse, a gel, And a styling agent composition which improves the style sustainability in a retention type styling agent such as wax.

In general, the main function of the hair is as follows. The hair protects the human body from external mechanical and chemical stimuli. That is, it prevents the entry of harmful substances and protects the human body from external stimuli such as cold, friction, and direct sunlight. Second, it has a cosmetic effect that decorates the appearance with decorative function. This is an important role that characterizes women and men. Third, it acts to transmit tactile sensation or pain by the sensory function.

Among them, decorative function has been regarded from ancient times in terms of cosmetic effects, and in recent years, with the emergence of perms, dyeing procedures, it has become a spotlight as a means of expressing personality more variously. In addition, the cosmetic used to form the hair style temporarily and to sustain the style is a styling composition, and examples thereof include a hair spray, a mousse, a gel, and a wax. Such a styling composition should have properties such as good durability so that a desired hair shape can be maintained for a long time, convenience in use without stickiness, easy washing ability, good gloss and softness to hair And the like.

Examples of the method of fixing and setting the hair of the styling composition include a method using a semi-solid or viscous holding component at room temperature, a type using a polymer resin, and a type using a moisturizer. In recent years, hair wax has been used increasingly, and high-melting-point holding components (carnauba wax, candelilla wax, microcrystalline wax, beads wax, paraffin wax, etc.) form a film on the surface of hair to give fixing power. Such a retaining ingredient allows hair to be naturally and smoothly retained, and re-styling becomes possible. However, most of the hair waxes used conventionally have a high tackiness, and the spreadability in the hands and hair is not good, so that the hair may be aggregated and greasy, and the washing power is also poor.

Next, the styling agent using the polymer resin is a hair spray, a hair mousse, a hair gel, etc., and the polymers such as pyrrolidone, acrylic acid, and acrylate are used alone or in the form of a copolymer thereof. Is evaporated and then attached to the hair through the formation of a film, which forms a fixing force on the hair to form a desired style. Such a styling agent has an excellent setting power as compared with a hair wax, has excellent applicability to hands and hair, and has an advantage of being well cleaned. However, there is a disadvantage in that a hard film is formed to cause a flaking phenomenon, a style may look unnatural, and re-styling is difficult.

Accordingly, the present inventors have made efforts to develop a styling composition capable of re-styling with excellent setting power and detergency, and as a result, it has been found that a polyacrylate crosspolymer-8 developed through a collaboration with Mitsubishi Chemical, The present inventors have found that the present invention can be applied to a polymer resin type styling agent to provide a styling effect and provide a natural feeling like a wax. In addition, when the present invention is applied to a retention type styling agent, it is found that the styling performance is improved.

Accordingly, an object of the present invention is to provide a styling composition which is excellent in setting power and detergency, and is capable of resilting, and having improved durability.

In order to achieve the above object, the present invention provides a styling composition comprising polyacrylate crosspolymer-8 as an active ingredient.

[Test Example 1] Evaluation of setting force

The setting powers of the hair styling compositions of Comparative Examples 1 to 4 and Examples 1 to 10 prepared above were measured using a rheometer (CR-500DX, SUN SCIENTIFIC CO., LTD., Japan). Each hair styling composition was applied uniformly to 2 g of hair tress by 0.5 g each, and then dried. The dried hair tress was mounted on a rheometer and pressed at a depth of 10 mm at a speed of 20 mm / min to measure the setting force by measuring the strength of the applied force. The average value measured by repeating the test five times was shown in Tables 4 and 5 Respectively.

Comparative Example 1 Comparative Example 2 Example 1 Example 2 Example 3 Example 4 Example 5 Setting force (gf) 138 210 159 147 152 170 189

Comparative Example 3 Comparative Example 4 Example 6 Example 7 Example 8 Example 9 Example 10 Setting force (gf) 125 201 150 135 143 165 191

As can be seen from the results of Tables 4 and 5, Examples 2 to 5 had better setting power than Comparative Example 1, Examples 7 to 10 had better setting power than Comparative Example 3, and hair spray (mist) By including polyacrylate crosspolymer-8 in the composition, the setting power is increased and the setting power is further increased as the content is increased. Also, the results of Examples 1 and 6 show that the use of polyacrylate crosspolymer-8 alone has excellent setting power.

Also, the results of Comparative Examples 2 and 4 show that setting strength is improved when the content of polyacrylate crosspolymer-8 is more than 6% by weight, but spraying is not easy in hair spray (mist), and transparency is inhibited in hair gel And it was found that stickiness is serious, which causes discomfort when used.

[Test Example 2] Evaluation of Persistence

The curl retention measurement method was used to evaluate the effect of the regular care composition of Comparative Examples 5 to 6 and Examples 11 to 14 on the hair style sustainability. 0.5 g of each of the stabilizer compositions of Comparative Examples 5 to 6 and Examples 11 to 14 was uniformly applied to 2 g of hair tress (length: 15 cm), followed by winding on a spiral and drying. The length of hair tress was measured by removing the curled hair tress from the screw thread, and then the length was measured again after 2 hours, 4 hours and 6 hours in a thermostat (25 °, 80% relative humidity). The curl retention (%) was calculated according to the following equation (1) as the average length measured after 5 measurements, and the sustained force was measured.

Lo: Hair tress (circle)

Lt: hair tress length after t time

Ls: First hair tress length immediately after curl formation

Elapsed time Comparative Example 5 Comparative Example 6 Example 11 Example 12 Example 13 Example 14 2 hours 69% 91% 74% 79% 85% 90% 4 hours 55% 83% 62% 69% 74% 81% 6 hours 42% 79% 49% 55% 66% 77%

As can be seen from the results shown in Table 6, Examples 11 to 14 have superior sustained durability with respect to elapsed time than Comparative Example 5. Through the inclusion of polyacrylate crosspolymer-8 in the hair wax composition, It can be confirmed that the sustainability is further enhanced.

Also, the results of Comparative Example 6 indicate that when the content of polyacrylate crosspolymer-8 exceeds 6% by weight, the sustaining power is increased but the stability of emulsification of the hair wax is impaired to make the surface condition poor and sticky, .

[Test Example 3] Satisfaction evaluation

After using the hair styling compositions of Comparative Examples 1 to 6 and Examples 1 to 14 prepared above, the setting power, the sustaining power, the resilience, the stickiness and the overall satisfaction were evaluated by a panel of 20 experts. Satisfaction level of each item was evaluated as 1, 3, 5, 7, 9 points (the higher the score was, the higher the satisfaction was), and the results were averaged as shown in Tables 7 to 9 below.

As can be seen from the results of Tables 7 and 8, in the hair spray (mist) and the hair gel composition, the setting force, the sustaining force, the resilience, the stickiness, and the satisfaction degree vary depending on the presence and content of the polyacrylate crosspolymer- As a result, it was found that the initial setting power, the sustainability, the flexibility, and the satisfaction were improved by entering the above components. In particular, the strength in the flexible portion is evaluated to be high, and it has been confirmed that the above-mentioned component provides a wax-like feeling in the polymer resin type styling agent and enables re-styling. However, when the content of the polyacrylate crosspolymer-8 exceeds 3 wt%, the stickiness gradually increases and the satisfaction is relatively low. When the content of the polyacrylate crosspolymer-8 exceeds 6 wt% , Overall satisfaction is low despite high scores in setting, persistence and flexibility.

As can be seen from the results of Table 9, changes in setting power, duration, flexibility (re-styling), stickiness and satisfaction according to the presence and content of polyacrylate crosspolymer-8 in the hair wax composition were observed. It was found that the setting power and especially the sustainability were improved by entering the ingredient. However, when the content of the polyacrylate crosspolymer-8 is more than 3% by weight, the stickiness gradually increases and the satisfaction is relatively low. When the content of the polyacrylate crosspolymer-8 exceeds 6% by weight, Despite the high scores on setting, persistence and flexibility, overall satisfaction is low due to stickiness.
