HAIR-PROTECTING COMPOSITION COMPRISING COLLAGEN AND MANUFACTURING METHOD THEREFOR

Abstract

A hair-protective composition includes collagen, a polyurethane binder, sericin and water. The collagen is contained in an amount of 10 wt % to 30 wt % based on a total weight of the hair-protective composition. A method of preparing the hair-protective composition includes melting collagen in water, dissolving sericin in the melted collagen and performing filtration and performing addition with a polyurethane binder and performing stirring.

DETAILED DESCRIPTION

[0019] Various embodiments of the present are discussed below.

[0020] Embodiments of the present disclosure pertain to a hair-protective composition including collagen, a polyurethane binder, sericin and water.

[0021] The collagen may be used without limitation, so long as it is collagen that is commonly used, and in embodiments, collagen prepared according to Korean Patent No. 10-1394230, in particular, Alaska Pollock collagen, is used. Here, the collagen may be contained in an amount of 10 to 30 wt % based on the total weight of the hair-protective composition.

[0022] The polyurethane binder may be prepared by mixing 50 parts by weight of polyoxyethylene polyoxypropylene, 20 parts by weight of polyester polyol, 10 parts by weight of isophorone diisocyanate, 10 parts by weight of N-methyldiethanolamine, 5 parts by weight of MEK oxime, 3 parts by weight of a bismuth-type carboxylate catalyst, and 2 parts by weight of dimethylformamide, and may be contained in an amount of 10 to wt % based on the total weight of the hair-protective composition.

[0023] The sericin may be used without limitation, so long as it is sericin that is commonly used, and may be contained in an amount of 1 to 10 wt % based on the total weight of the hair-protective composition.

[0024] In an embodiment, the hair may be synthetic hair or human hair.

[0025] In addition, the present disclosure pertains to a method of preparing a hair-protective composition including (a) melting collagen in water, (b) dissolving sericin in the melted collagen and performing filtration, and (c) adding a polyurethane binder thereto and performing stirring.

[0026] The preparation method of the present disclosure includes the step of melting collagen in water [i.e. step (a)]. In step (a), the amount of collagen that is contained may be as described above. In step (a), collagen is added to water and melted at about 25 to 35 C. for about 30 min to 2 hr with stirring.

[0027] The preparation method of the present disclosure includes the step of dissolving sericin in the melted collagen and performing filtration [i.e. step (b)]. In step (b), the amount of sericin that is contained may be as described above. In step (b), sericin is added thereto and then melted with additional stirring for about 30 min to 2 hr.

[0028] The preparation method of the present disclosure includes the step of adding a polyurethane binder thereto and performing stirring [i.e. step (c)]. In step (c), the properties and amount of the polyurethane binder that is contained may be as described above. In step (c), the polyurethane binder is added thereto and stirred for about 30 min to 2 hr, thus obtaining a viscous liquid hair-protective composition, which is referred to as AMICELL in the present disclosure.

[0029] When AMICELL thus prepared is used, it is very effective at allowing collagen to penetrate to the center of the hair, restoring the surface of damaged hair, reducing the cracking of the hair, increasing elasticity, and reducing the generation of static electricity, and is capable of exhibiting 50% retention of the hair-protective component even after washing 20 to 30 times, and of increasing a moisturized characteristic.

[0030] A better understanding of the present disclosure may be obtained through the following example and test example. However, the following example and test example are merely set forth to illustrate the present disclosure, and are not to be construed as limiting the scope of the present disclosure.

Example

1. Preparation of Polyurethane

[0031] 500 g of polyoxyethylene polyoxypropylene (aqueous modified), 200 g of polyester polyol (aqueous modified) and 100 g of isophorone diisocyanate were mixed for 30 min at 40 C. using a stirrer, after which 100 g of N-methyldiethanolamine, 50 g of MEK (methyl ethyl ketone) oxime, 30 g of a bismuth-type carboxylate catalyst and 20 g of dimethylformamide were further added thereto and mixed at 40 C. for 60 min, thus preparing a polyurethane binder.

2. Preparation of AMICELL

[0032] Alaska Pollock collagen was prepared as in Korean Patent No. 10-1394230. 200 g of Alaska Pollock collagen was added to 500 g of water, melted with stirring at 30 C. for 1 hr, added with 50 g of sericin, and further melted for 1 hr. The resulting product was filtered to thus remove agglomerated sericin. The resulting product was added with 250 g of the polyurethane binder prepared above and then stirred for 1 hr. The resulting hair-protective composition was a viscous liquid, and was referred to as AMICELL.

3. Use of AMICELL

[0033] The AMICELL stock solution thus prepared was mixed and diluted at 1:30 with purified water (pH 7.0 to 7.2, hardness 0.7 mol/m.sup.3). The wig was immersed in the diluted solution obtained as described above for about 2 to 20 min, and was then dried at 60 to 80 C.

Test Example

1. Hair Image Measurement

[0034] Human hair before and after treatment with AMICELL was observed using a microscope (3,700 and 430). Based on the results of observation thereof, as shown in FIGS. 1A and 1B, before using AMICELL, the surface of the hair was damaged, but after using AMICELL, the hair looked like natural hair similar to silk.

[0035] Also, as shown in FIGS. 2A, 2B and 2C, before using AMICELL, the hair was cracked at the ends, was loose, lacked moisture, and showed a weak thin hair shape, but immediately after using AMICELL, the cracking of the hair was alleviated and the hair was coated, showing a strong shape. In addition, cracking of the ends of the hair did not occur again for 1 month after using AMICELL, color fading caused by low moisture was alleviated, and the elasticity of the hair was maintained.

2. Penetration Test

[0036] Human hair before and after treatment with AMICELL was observed using a microscope, and the cross section of human hair, after allowing AMICELL mixed with a fluorescent substance to penetrate the hair, was measured through fluorescence. Based on the results of electron microscopy, as shown in FIGS. 3A, 3B and 3C, after treatment with AMICELL [FIG. 3B] compared to before treatment with AMICELL [FIG. 3A], the hair looked neat, and collagen was confirmed to penetrate all the way to the center of the hair [FIG. 3C].

3. Antistatic Test

[0037] The extent of generation of static electricity was measured before and after treatment of human hair with AMICELL in accordance with the Korean Industrial Standard KS K 0555 (electrostatic test method of fabrics and knitted fabrics). Based on the results thereof, in the case of using silicon, the static electricity of the hair was measured to be about 25,000 V, but when using AMICELL, the static electricity was measured to be 500 to 700 V, indicative of a superior effect of reducing static electricity.

4. Washing Test

[0038] The hair of a wig was treated with 100% AMICELL and then subjected to machine washing for 8 min (403 C., Sereen Dry After AC confirmed), and the amount of AMICELL remaining after washing was measured, and the retention thereof is shown in Table 1 below.

TABLE-US-00001 TABLE 1 Washing 1.sup.st 2.sup.nd 3.sup.rd 4.sup.th 5.sup.th washing washing washing washing washing Retention 98.3% 97.8% 97.0% 96.3% 95.2%

[0039] As is apparent from Table 1, it was confirmed that retention was 95% or more after washing five times and 50% after washing 20 to 30 times.

5. Moisturizing Test

[0040] In accordance with the Korean Industrial Standard KS K ISO6330 (home washing and drying process for textile testing), the moisturized characteristic of human hair was measured before and after treatment with AMICELL. Based on the results thereof, the moisturized characteristic was increased by 400% after treatment with AMICELL.
