Description

Hair cosmetics containing zinc pyrithione-polymeric quaternary ammonium salt complex

The present invention relates to a hair cosmetic containing a stable Zinc Pyrithione (ZPT) -Polyquaternium (PQ) (Polymeric quaternary ammonium salt; polymer quaternary ammonium salt) complex. More specifically, it contains a ZPT effective for preventing and removing dandruff and a hair complex containing PQ, which provides hair and treatment effects. Thus, hair cosmetics with excellent dandruff prevention and removal effects and improved hair and treatment effects It relates to the composition.

Dandruff is one of the most common microdermal fragments in the human body, and although it does not involve inflammation, it is the scale of a solid, keratinized scalp. It is characterized by being renewed. The root cause of dandruff development is not yet clearly identified, but in general, the biggest cause of dandruff is the abnormal release of keratinocytes and excessive secretion of sebum, and the proliferation of microorganisms has been pointed out as a deteriorating factor. In fact, more microbes were found on dandruff scalp, and in particular, many multiplications of microorganisms called Pyrosporum Ovlae were found. Therefore, when the growth of microorganisms are suppressed, dandruff symptoms will be improved, so-called anti-dandruff agent, which has a bactericidal action, is used for shampoo. Representative dandruff treatment agents include sullenium disulfide, zinc pyrithione (ZPT), and pyrotonolamine. All of these substances are effective antimicrobial agents and can reduce dandruff with two or three uses of cell division inhibitors. In particular, ZPT is most commonly used as a medicament for dandruff removal shampoo. Orentreicht explained through clinical trials that ZPT-containing shampoos are excellent in treating dermatitis and suppressing itching (N. Orentreich, J. Soc. Cosmet. Chem. 3, 189 (1970)).

On the other hand, examples of the hair cosmetic composition for the purpose of suppressing dandruff and itching include shampoo compositions containing ZPT as an active ingredient (US Pat. No. 4,323,683, US Pat. No. 4,470,982, EP 285,388). However, ZPT is insoluble in water and must be dispersed in the product using a typical synthetic clay dispersant such as bentonite. This is because ZPT exhibits poor solubility in water or solvents, and appears to be due to the formation of a nonbonding bond between O and Zn as an aromatic salt containing sulfur and zinc. That is, the dissolution mechanism of zinc pyrithione requires a ligand capable of coordinating covalent bonds with zinc, a heavy metal in zinc pyrithione, and suitable amines having ligands containing a non-covalent electron pair. For example, EDTA (Ethylenediaminetetraacetic acid) has been mainly used as a solvent (US Patent No. 3,940,382), and recently, N-acyl-EDTA chelating surfactant is used as a solvent of zinc pyrithione (Korean patent application) No. 97-9984) claim that finer particles of ZPT can be obtained. However, amines, such as EDTA, exhibit strong alkalinity with their own pH of 9 or more, and produce a strong specific odor. After dissolving ZPT, ZPT was dissolved by adding an acid such as hydrochloric acid to neutralize the pH of the composition. Since again forms an insoluble precipitate, the pH of the composition cannot be neutralized. On the other hand, in the case of N-acyl-EDTA chelating surfactants, for example, sodium lauroyl ethylenediaminetriacetate, N has unpaired electron pairs due to the steric hindrance effect of acyl groups bonded to N, i.e., due to the asymmetric structure. Because Zn of ZPT cannot be accessed efficiently, it cannot be considered that coordination coordination is sufficient. On the other hand, even in the shampoo for dandruff removal, the use of polymer quaternary ammonium salt is inevitable for the hair-setting and treatment effect, but its use has been extremely limited because it is incompatible with the finely granulated ZPT. Therefore, until now, it has been hardly seen that the hair cosmetic material using ZPT as a main component of dandruff removal and prevention, for example, shampoo, sufficiently contains the above-mentioned polymer quaternary ammonium salt. Thus, until now, the hairdressing and treatment effects of the shampoo for dandruff removal and prevention using ZPT have been mainly obtained using nonionic silicone emulsions. However, in the case of silicone emulsion, it is difficult to stabilize, so the emulsion that is pre-emulsified should be added at low temperature below 60 ℃, and since it is hydrophobic itself, it can lower the foaming ability of the shampoo and weaken the function of the shampoo, and the viscosity of the product, hydrophilicity-hydrophobic balance If the value (HLB value) and pH were not suitable, the product could be easily separated and stabilized, making it difficult to stabilize.

In order to solve the above problems, the present inventors, the problem of stability and effect of the composition according to the precipitation formation of ZPT, strong specific odor problem of the composition due to the strong alkali, excellent quaternary and treatment effect of the polymer quaternary ammonium salt and In order to solve the problems such as instability due to the formation of insoluble complexes in common use, we found the mechanism that ZPT forms a complex with polymer quaternary ammonium salts. As a result, ZPT has a strong bond strength with polymer quaternary ammonium salts. The binding was related to the type and molecular weight of the quaternary ammonium salt and the number of quaternary cations in the quaternary ammonium salt, and not to the particle size of ZPT. In addition, ZPT-PQ (Zinc Pyrithione-Polymeric quaternary ammonium salt) composite having a surface activity was prepared by dispersing and stabilizing the composite of ZPT and the quaternary quaternary ammonium salt, and then using it in the preparation of the hair cosmetic composition. The present invention has been completed by discovering that the surface activity and steric hindrance effect of the composite can further improve the stability of the generally unstable hair cosmetic composition containing ZPT and silicone emulsion.

Accordingly, an object of the present invention is to provide excellent anti-dandruff by containing a stable ZPT-PQ complex of anti-dandruff fungal zinc pyrithione (ZPT) which improves dispersion stability and polycutternium (PQ) which gives excellent hair removal and treatment effect. And it provides a hair cosmetic composition having a prophylactic effect and a hairdressing and treatment effect.

The object of the present invention is to add ZPT to polycutterium (PQ) and stir while heating to form ZPT-PQ (Zinc Pyrithione-Polymeric quaternary ammonium salt) complex and homo homomixer, dispenser, ball mill, colloid mill, ultrasonic vibrator The dispersion stability of the stabilized ZPT-PQ composites after dispersion and the like was investigated in comparison with the ZPT aqueous solution, ZPT aqueous solution dissolved in EDTA, and the non-dispersed ZPT-PQ composite. Subsequently, a hair cosmetic composition containing the dispersion stabilized ZPT-PQ composite and a silicone emulsion was prepared, and the stability of the hair cosmetic composition was observed by observing the formation of sediment over time, and the hair was actually treated with dandruff. The cosmetic composition was applied to confirm the effect of reducing dandruff and itching in clinical trials, and was also achieved by preparing a hair cosmetic composition in which ZPT, PQ, and silicone emulsion were mixed together and examining the stability of the hair cosmetic composition.

Hereinafter, the configuration and operation of the present invention.

ZPT-PQ (Zinc Pyrithione-Polymeric quaternary ammonium salt) complex by mixing ZPT in an aqueous PQ solution containing PQ-10 and PQ-11 dissolved in PQ-10 and PQ-11, respectively, in 80 ° C water Preparing a dispersion and stabilizing it with a ball mill, a homomixer, a colloid mill, a super-impact vibrator, etc .; Preparing a ZPT-GHTC composite by mixing JPT in an aqueous solution of Guar hydroxypropyltrimonium Chloride (GHTC) and dispersing and stabilizing the same in the same manner as described above; The dispersion state of the microparticles of the dispersed stabilized ZPT-PQ-10 composite was visually observed, and in the same manner, a 2 wt ZPT aqueous solution, a 2.0 wt ZPT aqueous solution dissolved in 0.5EDTA, and a 2.8 wt ZPT-PQ-10 without redispersion Investigating the dispersion stability of the dispersion stabilized ZPT-PQ composite by observing the dispersion state of the composite and comparing the size of the particles after drying the materials to determine the suitability when applied to the hair cosmetic composition; Preparing a hair cosmetic composition containing a dispersion-stabilized ZPT-PQ-10 and ZPT-PQ-11 composite and a silicone emulsion, and a hair cosmetic composition containing a ZPT and PQ single component and a silicone emulsion; Comparing the stability of the hair cosmetic composition of the present invention by observing the production of precipitate under a microscope while keeping the prepared hair cosmetic composition and visually observing the layer separation of the silicone emulsion; After applying the present invention hair cosmetic composition to a lot of dandruff male consists of a clinical trial step to investigate the anti-dandruff effect and the anti-itch effect.

ZPT used as an anti-dandruff bacterium in the present invention is a divalent aromatic salt having a very low solubility in water and used industrially as a spherical form having a particle size of 0.3-10 μ, the structure of which is represented by the following formula (I): As shown.

PQ to make a composite with ZPT in the present invention is a polymer quaternary ammonium salt mainly used in hair cosmetics to give hair and treatment effect to prevent the static electricity, gloss, damage of hair and the like. The solubility in water and the polymer properties are determined depending on the molecular weight, the number of quaternary ammonium groups substituted in the molecule, and the properties of alkyl groups substituted with the ammonium groups. PQ used in the present invention is a PQ-1, PQ-2, PQ-4, PQ-5, PQ-8, PQ-9, PQ-10, PQ which is industrially used as having a suitable molecular weight and water solubility -11, PQ-12, PQ-13, PQ-14, PQ-15, PQ-17, PQ-18, GHTC and the like, and the structure is as outlined in the following formula (II).

Wherein R ₁ , R ₂ , R ₃ , R ₄ are alkyl, acyl, alkylamine, alkylester groups substituted with N, X is the anion of the quaternary ammonium, and n is the degree of polymerization.

In the present invention, the ratio of ZPT and PQ used to prepare the ZPT-PQ composite may vary depending on the nature of the PQ, but is preferably 1: 0.05 to 1:10 by weight.

The production of the ZPT-PQ composite of the present invention can be seen as possible by the water-mediated hydrogen bond between ZPT and PQ and the van der Waals bond between the hydrophobic groups of both ZPT and PQ. Originally, the solubility of ZPT itself is low solubility and weak reactivity due to the bonding force between the electronegative O and the electropositive Zn in water.

The ZPT-PQ composite of the present invention maintains the hair dressing and treatment effects of PQ by binding ZPT to the reaction site of PQ on a molecular basis, thereby improving the dispersion efficiency of ZPT and maintaining the film-forming properties of PQ. In particular, since ZPT-PQ composites have an interfacial activity, they adsorb well on the scalp and hair to form a flexible thin film. Thus, when the ZPT used solely during drying is removed as a powder, the dandruff removal effect and flaking phenomenon of hair are generated. Roughness can be prevented, and due to the surface activity of ZPT-PQ hydrophobized than PQ, it has the effect of more stabilizing the hair cosmetic composition containing a silicon emulsion.

In the present invention, the ZPT-PQ composite has antiseptic effect, antiseptic disinfection effect, hair hairdressing and treatment effect, foaming force, dispersion force, film forming ability, and the like, and has a dispersion stabilizing effect in a composition used with a silicone emulsion.

In the present invention, the ZPT-PQ composite is less hydrophilic than the polymeric quaternary ammonium salt, which is transparent, thus making the solution suspended even at a significantly lower concentration. The ZPT-PQ composite thus formed is more stably dispersed in the anionic shampoo composition due to the reduced cationicity of the PQ, resulting in a lower probability of forming a complex with the anion than the PQ itself. When ZPT-PQ composite is used together with silicone emulsion, the hydrophobic part is compatible with hydrophobic silicone, so the cationic polymer part, which is present at the interface of the silicone emulsion in the shampoo base and the hydrophilic part, is electrostatically repulsive and steric hindrance. The effect improves the stability of the silicon emulsion. In addition, the ZPT-PQ complex has a surface activity, so it is more uniformly adsorbed to the scalp and hair and the overall cationicity is weakened, but due to the cationicity of the partially unbonded portion, it may be more efficiently adsorbed to the scalp than ZPT itself. It can be used more efficiently because it is not washed off more easily than when contained in ZPT alone. In the test for the detection of residual ZPT after actual shampoo use with iron chloride (FeCl ₂ ), the ZPT-PQ complex was found to remain after 4 rinses, and the ZPT in the product used as the microparticle ZPT itself was almost in two rinses. It was found that it was removed.

Since ZPT-PQ complexes can bind Mg ⁺⁺ , Zn ⁺⁺ and Ca ⁺⁺ to their unreacted quaternary ammonium, EDTA (ethylenediaminetetraacetic acid), a commonly known chelate, may not be used. When used in combination, the effect can be enhanced.

As described above, the ZPT-PQ composite is a cationic polymer and exhibits interfacial activity, thereby increasing anti-dandruff effect by more uniformly and more strongly binding to the scalp and hair.

Specific examples of ZPT-PQ composites include ZPT-PQ-1, ZPT-PQ-2, ZPT-PQ-4, ZPT-PQ-5, ZPT-PQ-6, ZPT-PQ-8, ZPT-PQ-9, ZPT-PQ-10, ZPT-PQ-11, ZPT-PQ-12, ZPT-PQ-13, ZPT-PQ-14, ZPT-PQ-15, ZPT-PQ-18, ZPT-GHTC, etc. These ZPT-PQ complexes are entangled in opaque gels at high concentrations of PQ and form a mixture of homogeneous opaque gels and fine ZPT particles at low PQ concentrations.

For example, it may be formulated as a shampoo, hair conditioner, hair conditioner, hair cream, hair tonic, hair treatment cream, hair treatment pack, hair spray, hair gel, hair cream and the like. The compositions of each of these formulations contain the ZPT-PQ complex of the present invention and contain various components necessary for the commercialization of each formulation, and the types and amounts of these various components can be suitably selected as necessary, and the ZPT-PQ composite of the present invention. Silver can generally be used in amounts of 0.01-20 weight, preferably 1-10 weight, based on the total weight of the composition.

In the present invention, when ZPT and PQ are respectively added to the hair cosmetic composition, ZPT may be used in an amount of 0.01 to 5 weights, preferably 0.1 to 2 weights, and PQ in 0.01 to 20 weights, preferably 1 to 10 weights. have.

Hereinafter, the specific method of the present invention will be described in detail with reference to Examples, but the scope of the present invention is not limited only to these Examples.

Example 1 Preparation of Dispersion Stabilized ZPT-PQ Composites

ZPT-PQ-10 composite was prepared by mixing 100 g of ZPT (48) having a spherical particle size of 0.3-10 μ with 1 Kg of PQ-10 made from two aqueous solutions. At this time, the production reaction was carried out using a high speed stirrer of 2000 to 4000 RPM mainly at 70 ~ 100 ℃. Since the ZPT-PQ-10 composites are entangled in a gel state, 70-100 using a homomixer, a disperser, a ball mill, a colloid mill, an ultrasonic vibrator, etc., which have a strong dispersing force to bond ZPT to PQ-10 on a molecular basis. The dispersion was stabilized at 1 ° C. for 1-2 hours. Dispersion stabilization was determined by the bonding state of the composite and the performance of the dispersing device. In addition, ZPT-PQ composites are prepared in the same manner as above, but the same ZPT is used, but PQ is PQ-1, PQ-2, PQ-4, PQ-5, PQ-8, PQ-9, PQ-11, and PQ. Final ZPT-PQ-1, ZPT-PQ-2, ZPT-PQ-4, ZPT with -12, PQ-13, PQ-14, PQ-15, PQ-16, PQ-17, PQ-18 respectively -PQ-5, ZPT-PQ-8, ZPT-PQ-9, ZPT-PQ-11, ZPT-PQ-12, ZPT-PQ-13, ZPT-PQ-14, ZPT-PQ-15, ZPT-PQ -16, ZPT-PQ-17, ZPT-PQ-18 were prepared and dispersion stabilized in the same manner as well.

Example 2: Preparation of Dispersion Stabilized ZPT-GHTC Composite

In the present Example, Example 1 was also prepared in the same manner ZPT-PQ composite, but the same ZPT using the same but PQ using the GHTC to prepare the final ZPT-GHTC and also stabilized dispersion by the same method. At this time, the GHTC used is Jaguar C13S manufactured by Celanse.

Experimental Example 1: Dispersion Stability of ZPT-PQ Composite

In this Experimental Example, the dispersion stability of the dispersion stabilized 2.8wtZPT-PQ-10 composite (Sample 4) prepared in Example 1 was 2.0 wtZPT solution itself (Sample 1), 2.0EDZPT solution which improved the stability by finely dissolving 0.5EDTA. (Sample 2), the dispersion stability of the 2.8wtZPT-PQ-10 composite (Sample 3) that was not redispersed was compared and the adhesion and particle state during drying were investigated. In the method, the microscopic state was observed with the naked eye, and all ZPTs finely stabilized with ZPT or EDTA used in the ZPT solution itself were used as fine particles of about 0.3 to 10 μm. As a result, the samples 1, 2, 4, etc. were observed to produce a fine and stable dispersion in the supernatant in the aqueous solution, but as shown in Table 1, the samples 1 and 2 were found to be solid insoluble mass at the base. On the other hand, in the case of sample 4 of the present invention, a solid lump was not found. On the other hand, when comparing the state after the sample solution is dried, Samples 1 and 2 were considerably non-uniform and formed large and coarse dry particles, and the powder was blown after complete drying. Sample 3 showed large lumps of undispersed ZPT-PQ composites in aqueous solution and white undispersed aggregates after drying. On the other hand, the dispersion-stabilized ZPT-PQ-10 composite sample 4 of the present invention could not find coarse particles after drying, and formed a smooth film with good adhesion and uniformity. This is because the dispersion-stabilized ZPT-PQ-10 composite of the present invention is more uniformly present in the solution and more uniformly adheres to the scalp and hair when used as a cosmetic composition. Indicates that it can be improved.

Experimental Example 1: Comparison of the stability of the hair cosmetic composition

In the present experimental example, in order to accurately evaluate the stability of the hair cosmetic composition prepared in Examples 3 to 7 over time, the macroscopic visual evaluation was performed first, and the second microscopic evaluation was performed. First, the shampoo compositions of Comparative Examples 1 and 2 and Examples 3, 4, 5, 6, and 7 were stored at room temperature (25 ° C.) for 3 months and at 40 ° C. for 2 months. Confirmed. As a result of the experiments, as shown in Tables 4 and 5, in the case of Comparative Examples 1 and 2 in which the general constituents of the shampoo and the silicone emulsion or the chelated EDTA-2Na were used together, a float or a float and a precipitate were formed soon over time. Could check. In Comparative Example 1, the relatively small specific gravity and hydrophobic silicon emulsion were found to be mostly rich. In the case of Comparative Example 2, in which the silicon emulsion and ZPT were used together with the chelate EDTA-2Na, the ZPT was relatively high. Almost completely precipitated and most of the silicon emulsion was suspended. On the other hand, in Examples 3, 4, and 5, the floating phenomenon of silicon emulsion and the precipitation of ZPT were hardly found, and the hair shampoo cosmetic composition prepared by containing ZPT and PQ of Examples 6 and 7 as a single component was also carried out. Better results than in Examples 3-5. That is, in the case of Examples 6 and 7, it was good up to 1 month at 40 ° C, but after 2 months, precipitation occurred, resulting in poor safety. In addition, after observing the particle state immediately after the manufacture of Example 3 for 2 months at 40 ℃ and the particle state under a microscope (400 times magnification, Olympus Microscope), as shown in Figure 1 finely dispersed particles at the beginning of the test Was observed as little change.

Experimental Example 2: dandruff reduction and itching prevention effect

Efficacy test on the dandruff of the shampoo cosmetic composition containing the ZPT-PQ-10 complex and the shampoo cosmetic composition prepared by containing ZPT and PQ-10 as a single component was performed. 42 males of 16-40 years old with relatively high dandruff were selected and the shampoo cosmetic composition containing ZPT-PQ-10 complex of the present invention of Example 3 and the shampoo cosmetic composition containing ZPT and PQ-10 as a single component Example 6 And for each of the shampoo cosmetic composition of Comparative Example 2 containing no ZPT and PQ-10 divided into three groups of 14 people each was tested. The first group is in the order of Comparative Example 2, Example 3, Example 6, the second group is in the order of Example 3, Example 6, Comparative Example 2, and the third group is Example 6, Comparative Example 2, In order of Example 3, one product was used for 2 months each. In addition, compared to the effect of the shampoo cosmetic composition of the present invention using a commercial shampoo for 15 days before the present dandruff reduction effect experiment. In this experiment, each tester triturates once every three days and until the dandruff appears or itching is felt, the intensity is displayed. As a result, as shown in Table 6, Example 3 which is a ZPT-PQ-10 complex-containing shampoo cosmetic composition of the present invention, Comparative Example 2 containing only ZPT as well as ZPT and PQ- Compared with the product of Example 6 containing 10-valent monocomponent, it was found that the anti-dandruff production and itching prevention effect was shown. As a result of comparing Comparative Example 2 and Example 6, it was found that Example 6 is superior to Comparative Example 2. From these facts, ZPT of the dispersion stabilized ZPT-PQ-10 complex of the present invention is more stably dispersed and utilized more effectively than the anti-dandruff ZPT is used alone.
