Description

Technical Field

[0001] The invention relates to the technical field of hair wax compositions, and in particular to a mild hair wax composition that can withstand corrosion and will not turn white, and a preparation method thereof. Background Art

[0002] Hair wax is a cosmetic product mainly used to beautify hairstyles. It is used for modifying and shaping hair. Therefore, its mildness, applicability, styling effect and retention effect have become indicators for judging the quality of hair wax.

[0003] Commercially available hair wax compositions generally contain 20-35% of cetearyl alcohol polyether as a thickener. Cetearyl alcohol polyether is a non-ionic surfactant. Since it is a preservative neutralizer, it will cause most cosmetic preservatives to enter its aqueous solution micelles, be wrapped up, and lose their preservative effectiveness.

[0004] Based on the above defects, the common practice in the market is to add highly irritating and efficient fungicides, such as methylisothiazolinone, methylisochlorothiazolinone, chlorphenesin, DMDM ​​hydantoin, etc., to be added alone or in combination to cope with product characteristics. Specifically, after the cetearyl alcohol polyether in the hair wax component is mixed with water, it forms micelles that will wrap the preservatives. Although the existing highly irritating and efficient fungicides can reduce the free concentration of preservatives in water, they will also lead to a decrease in the antibacterial rate. In addition, the existing highly irritating and efficient fungicides also have the ability to penetrate microbial cell membranes efficiently and quickly. Therefore, the use of the above preservatives for preservation in the prior art will cause greater irritation to the skin.

[0005] Furthermore, experimental tests have found that when the hair wax composition contains 20-35% of cetearyl alcohol polyether, the liquid will become fluid at above 45°C. However, in many countries such as Africa, Europe and the United States, the outdoor temperature is often higher than 45°C in the summer, which will cause the liquid to become fluid and unstable during transportation. Summary of the invention

[0031] 3.

DETAILED DESCRIPTION

[0034] A mild hair wax composition that can withstand antiseptic challenges without turning white, the hair wax composition comprising water, a thickener, propylene glycol, disodium ethylenediaminetetraacetic acid, a moisturizer, a water-retaining agent, a hair conditioner, a preservative and a fragrance, and the thickener is added in an amount of 30 to 41% by mass;

[0035] The thickener includes ceteareth-25, ceteareth-30 and ceteareth-40;

[0036] The preservatives include K708 preservative and K805 preservative, or the preservatives include K708 preservative and K820 preservative.

[0037] In order to achieve effective preservation of the hair wax composition while ensuring that the product is mild and non-irritating, the technical solution uses a combination of K708 preservative and K805 preservative, or a combination of K708 preservative and K820 preservative as the preservative of the hair wax composition. Specifically, the K708 preservative (ingredients include colloidal silver (200 ppm) and water), K805 preservative (ingredients include methylparaben, 1,2-hexanediol, ethylhexylglycerin, glycerin and phenoxyethanol) and K820 preservative (ingredients include phenoxyethanol, benzyl alcohol and glycerin) used in this scheme are all purchased from Kosen New Material Technology (Guangzhou) Co., Ltd.; among them, the K708 preservative in the formula is a metallic silver preservative. Unlike traditional preservatives, metallic silver preservatives can prevent non-ionic surfactant micelles from being encapsulated and slowly released in water, thereby achieving the purpose of inhibiting bacteria; and the K805 preservative or K820 preservative in the formula, although it will lose the ability to penetrate the mold cell membrane after being encapsulated by micelles in the hair wax composition, it still has a good penetration rate on the bacterial cell membrane, thereby having a good antibacterial effect on bacteria. This solution inhibits bacteria through K708 preservatives, and inhibits mold through K805 preservatives or K820 preservatives, so that the two preservatives work synergistically, thereby having a good inhibitory effect on microorganisms, and can break through the micellar solution of the hair wax composition and enter the microbial cell membrane, making it impossible for the microorganisms to reproduce, thus achieving a good antiseptic effect. It should be noted that the above-mentioned types of preservatives are mild and non-irritating, and can also effectively balance the product mildness of the hair wax composition.

[0038] Further, experimental tests have found that the hair wax composition contains 20-35% of cetearyl alcohol polyether, and when it is above 45°C, the liquid will become fluid, and many countries such as Africa, Europe and the United States are often higher than 45°C outdoors in summer, which will cause the liquid to be fluid and unstable during transportation. In the prior art, different types of cetearyl alcohol polyether have different melting points. The lower the melting point, the lower the melting temperature, and the more stringent the requirements for transportation. The higher the melting point of cetearyl alcohol polyether, the higher the melting point, which will cause the melting temperature to become higher. At the same time, the hardness of the liquid of the hair wax composition will be very high, which is difficult to pick and use, resulting in the disadvantages of being difficult to spread and having large resistance during the application process. Therefore, in order to improve the stability of the hair wax composition, this scheme uses low-melting-point cetearyl alcohol polyether-25, medium-melting-point cetearyl alcohol polyether-30 and high-melting-point cetearyl alcohol polyether-40 to combine, reduce the fluidity of the hair wax composition at 50 degrees Celsius, can meet the transportation conditions of high-temperature countries such as Africa, Europe and the United States, and has good stability.

[0039] Furthermore, in the hair wax composition, since the compatibility of cetearyl alcohol polyether with the polymer is poor, if a styling polymer incompatible with cetearyl alcohol polyether is added to the composition, the combination will appear opaque. Therefore, in order to improve the aesthetics of the hair wax composition after use, the present solution avoids adding a styling polymer incompatible with cetearyl alcohol polyether to the composition, but uses a combination of cetearyl alcohol polyethers with different melting points to achieve the styling effect of the hair wax composition, so as to take into account both the aesthetics and the styling effect.

[0040] It should be noted that this solution also adds disodium ethylenediaminetetraacetic acid as a chelating agent in the formula, which can effectively chelate most of the metal ions in pure water and play an auxiliary anti-corrosion role.

[0041] Further illustrating, the moisturizer includes glyceryl polyether-26, PEG / PPG-17 / 6 copolymer, methyl gluceth-10, PPG-24-glyceryl polyether-24, PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerol, PPG-12-butanol polyether-16, PEG / PPG-14 / 7 dimethyl ether and diethoxyethyl succinate.

[0042] Since high-melting-point cetearyl alcohol polyether has good heat-resistant stability, adding high-melting-point cetearyl alcohol polyether to the formula may cause large smearing resistance, difficulty in spreading, and easy clumping during use, which may cause great trouble in the process of hair styling and braiding. Therefore, in a preferred embodiment of the present technical solution, in order to improve the smearing resistance and smearing clumping phenomenon, so that the hair wax composition has a better user experience, the present solution also optimizes the type of moisturizer, which can effectively improve the thixotropy of the slurry without affecting the thermal stability of the slurry, and the shear force generated by applying it on the hair and the hand makes the slurry thinner and easier to spread on the hair, which has better hair braiding, styling and other use effects.

[0043] It is further described that the water retaining agent includes betaine, erythritol and trehalose.

[0044] To further illustrate, the hair conditioning agent includes polysilicone quaternary ammonium salt-26 and polysilicone quaternary ammonium salt-20.

[0045] In addition, the physical properties of cetearyl alcohol polyether are a white solid substance. When dissolved in water, it will form a colorless transparent gel. However, after being applied to the hair, the water evaporates and the concentration of cetearyl alcohol polyether increases, and it will become a white flaky solid that adheres to the hair, resulting in an unsightly look after the style dries.

[0046] Therefore, in order to improve the above situation, the technology on the market generally adopts the addition of humectants such as glycerin, propylene glycol, butylene glycol, sorbitol, PEG-7 glyceryl cocoate to retain moisture, but this solution has a major disadvantage, which will affect the thermal stability of the hair wax composition, reduce the melting point of the composition, and the anti-whitening effect is general.

[0047] In the technical solution of the present invention, different types of water-retaining agents and hair conditioners are added to the formula. The above raw materials can adhere to the hair or skin and form a thin film. The above film can reduce the volatilization rate of water in the composition without affecting the melting point of the hair wax composition, thereby effectively improving the whitening phenomenon of the hair wax composition after being used for a period of time.

[0048] It is further stated that the preservatives are K708 preservative and K805 preservative;

[0049] According to mass percentage, the hair wax composition comprises 38-65% water, 10-15% cetearyl alcohol polyether-25, 15-18% cetearyl alcohol polyether-30, 5-8% cetearyl alcohol polyether-40, 5-8% propylene glycol, 0.05-0.15% disodium edetate, 0.2-1.5% glycerol polyether-26, 0.2-1% PEG / PPG-17 / 6 copolymer, 0.2-1% methyl glucol polyether-10, 0.2-1% PPG-24-glycerol polyether-24, 0.2-1% PE It is composed of G / PPG / polybutylene glycol-8 / 5 / 3 glycerin, 0.5% PPG-12-butanol polyether-16, 0.2-1% PEG / PPG-14 / 7 dimethyl ether, 0.2-1% diethoxyethyl succinate, 0.2-1% betaine, 0.2-1% erythritol, 0.2-1% trehalose, 0.2-2% polysilicone quaternary ammonium salt-26, 0.2-2% polysilicone quaternary ammonium salt-20, 0.3-0.8% K708 preservative, 0.5-0.8% K805 preservative and 0.1-1% fragrance.

[0050] It is further stated that the preservatives are K708 preservative and K820 preservative;

[0051] According to mass percentage, the hair wax composition comprises 38-65% water, 10-15% cetearyl alcohol polyether-25, 15-18% cetearyl alcohol polyether-30, 5-8% cetearyl alcohol polyether-40, 5-8% propylene glycol, 0.05-0.15% disodium edetate, 0.2-1.5% glycerol polyether-26, 0.2-1% PEG / PPG-17 / 6 copolymer, 0.2-1% methyl glucol polyether-10, 0.2-1% PPG-24-glycerol polyether-24, 0.2-1% PPG-24-glycerol polyether-24, It is composed of EG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, 0.5% PPG-12-butanol polyether-16, 0.2-1% PEG / PPG-14 / 7 dimethyl ether, 0.2-1% diethoxyethyl succinate, 0.2-1% betaine, 0.2-1% erythritol, 0.2-1% trehalose, 0.2-2% polysilicone quaternary ammonium salt-26, 0.2-2% polysilicone quaternary ammonium salt-20, 0.2-0.8% K708 preservative, 0.5-1% K820 preservative and 0.1-1% fragrance.

[0052] This solution also optimizes the ratio of raw materials in the formula, wherein the addition amount of K708 preservative and K805 preservative / K708 preservative and K820 preservative is optimized, which is conducive to taking into account both the antiseptic effect and production cost of the hair wax composition.

[0053] Furthermore, if the amount of moisturizer added in the formula is too high, the product cost will increase and the cost performance will be reduced; if the amount of moisturizer added is too low, the moisturizing effect will be reduced and the whitening speed of the liquid will be accelerated. Optimizing the amount of moisturizer and hair conditioner added is conducive to taking into account both the production cost and the moisture retention effect of the hair wax combination.

[0054] To further illustrate, the melting point of the ceteareth-25 is 55-58°C, the melting point of the ceteareth-30 is 60-62°C, and the melting point of the ceteareth-40 is 65-70°C.

[0055] To further illustrate, the fragrance is essence.

[0056] A method for preparing a mild hair wax composition that can withstand antiseptic challenges without turning white, which is used to prepare the hair wax composition, comprising the following steps:

[0057] A. Put water, thickener, propylene glycol and disodium ethylenediaminetetraacetate into a stirring pot, heat to 80-85° C., and stir for 10-30 minutes to obtain a first mixture;

[0058] B. After lowering the temperature of the first mixture to 70-75° C., the moisturizer, water retaining agent and hair conditioner are added into a stirring pot, and stirred for 10-30 minutes to obtain a second mixture;

[0059] C. Put part of the second mixture into a rotary pot, and after the temperature of the second mixture is reduced to 65-68° C., put the preservative and the fragrance into the rotary pot, and stir for 10-20 minutes to obtain a third mixture;

[0060] D. Filling the third mixture at a temperature of 65-68° C. and cooling it in a freezing tunnel to obtain a hair wax composition;

[0061] E. Repeat steps C and D until all the second mixture of step B is filled.

[0062] The technical solution also proposes a method for preparing the above-mentioned hair wax composition. Compared with the existing preparation method, the preparation method of the solution has the following advantages:

[0063] First, the composition is filled at a temperature of 65-68° C. to maintain the fluid properties of the composition and facilitate filling.

[0064] Second, the composition needs to be quickly cooled down through a freezing tunnel after filling. Otherwise, it needs to wait until the temperature drops to 50°C after filling to form a solid gel. Before the solid gel is formed, the finished product cannot be packaged, which will cause the liquid to spill and overflow.

[0065] Third, the composition needs to be packaged into a turnover pot (i.e., a small-capacity constant temperature pot) in batches before adding preservatives and fragrances; if added to a large-capacity stirring pot, the filling speed cannot be too fast, which will lead to the degradation of the preservatives and fragrance components. Therefore, preservatives and fragrances need to be added to the turnover pot in small batches to reduce the insulation time of the preservatives and fragrances and reduce the degradation rate.

[0066] In the prior art, a lot of foam may occur in the hair wax composition after filling, making the surface of the filled liquid unsightly. In some embodiments, the composition can be sprayed with 95wt% ethanol after filling to defoam, so that the surface of the filled liquid is smooth and beautiful.

[0067] To further illustrate, in step D, the temperature of the freezing tunnel is -30 to -45°C.

[0068] The technical solution of the present invention is further illustrated below through specific implementation methods.

[0069] A. Add water, thickener, propylene glycol and disodium ethylenediaminetetraacetate according to the formula in Table 1 below into a stirring pot, heat to 80° C., and stir for 20 minutes to obtain a first mixture;

[0070] B. After the temperature of the first mixture is lowered to 70° C., the moisturizer, water retaining agent and hair conditioner in the amount of the formula in Table 1 below are added into a stirring pot, and stirred for 20 minutes to obtain a second mixture;

[0071] C. Put part of the second mixture into the rotary pot, and after the temperature of the second mixture is reduced to 65° C., put part of the formula amount of the preservatives and fragrances in the formula amount of the following Table 1 corresponding to the above second mixture into the rotary pot, and stir for 15 minutes to obtain a third mixture;

[0072] D. After filling the third mixture at a temperature of 65° C., cooling it in a freezing tunnel to obtain a hair wax composition; wherein the temperature of the freezing tunnel is -45° C.;

[0073] E. Repeat steps C and D until all the second mixture of step B is filled.

[0112] From the performance test results of Example 1 and Comparative Example 5, it can be seen that Comparative Example 5 only adds propylene glycol as a humectant to the formula, so its non-whitening test result after drying is only medium. This solution adds different types of humectants, water-retaining agents and hair conditioners to the formula compared with the prior art. The above raw materials can adhere to the hair or skin and form a thin film. The above film can reduce the volatilization rate of water in the composition without affecting the melting point of the hair wax composition, and effectively improve the whitening phenomenon of the hair wax composition after a period of use.

[0113] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
