Description

Technical Field

[0001] The invention relates to the field of cosmetics, and in particular to a hair wax and a preparation method thereof. Background Art

[0002] Hair wax is mainly a cosmetic product that beautifies hair styles and is used for hair modification and styling. Applicability, styling effect, and retention effect have become indicators for judging the quality of hair wax. Currently, there are several main systems of hair wax on the market: O / W system, in which the oil phase of the hair wax mainly uses volatile silicone oil and high-melting-point vegetable wax, and the water phase is mainly made of copolymers such as acrylates or polyurethanes, but too much oil esters will destroy the continuity of the polymer and produce more white flakes; W / Si system, in which the hair wax of this system has high transparency and good brightness, but it is too oily and difficult to wash off; full oil system, in which the hair wax of this system mostly uses mineral oil as a solvent, which has a good styling effect and high viscosity, but is easy to adhere to dust. Summary of the invention

[0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a hair wax with good spreadability, strong stability, good styling effect and hair style retention effect and a preparation method thereof.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a hair wax, comprising the following components: sodium polystyrene sulfonate, an emulsifier and a hair conditioner, wherein the emulsifier is composed of ceteareth-25 and ceteareth-30.

[0005] In a first aspect, the present invention provides a hair wax, which has good spreadability, excellent styling effect, long styling retention time, and good stability.

[0006] Sodium polystyrene sulfonate is a multifunctional polymer. In hair wax, it can form a transparent, elastic film, shrink when drying, and quickly conduct static electricity to prevent dust from sticking, without white flakes, and has a good styling effect.

[0007] Emulsifiers can stably mix water and oil-immiscible substances to form emulsions. Among them, ceteareth-25 is a nonionic emulsifier obtained by adding natural saturated fatty alcohols and ethylene oxide. Its hydrophilic-hydrophobic balance (HLB) value is 16.2, with strong emulsification ability, high emulsification efficiency and excellent emulsification performance. The emulsion made from it has a glossy and delicate appearance, generates significant viscosity and maintains viscosity stability.

[0008] Among them, ceteareth-30 is a universal emulsifier with an HLB value of 17.3. It is compatible with various oils and active ingredients. It is a very effective protective colloid for stabilizing various dispersion systems and can be used in combination with other emulsifiers. Ceteareth-30 has a good styling effect, but its melting point is higher than that of ceteareth-25. Too high a content in hair wax will lead to a higher melting point of the hair wax. In actual production, coagulation will occur, thus affecting filling. Ceteareth-25 and ceteareth-30 have good stability in production through reasonable ratio optimization, especially good high temperature stability, and stable production batches. The above two together with sodium polystyrene sulfonate can improve the ease of application, aesthetic effect, shape retention effect and stability of hair wax.

[0009] Hair conditioners can improve the appearance of hair, make hair more flexible, make hair easier to style, improve the hair's luster, and improve the texture of hair that has been damaged by chemical or physical effects.

[0010] The hair wax prepared by compounding sodium polystyrene sulfonate with the above components is easy to apply, has excellent hair styling effect and hairstyle retention effect, does not produce white flakes, and can keep the hair beautiful, shiny and not greasy. Furthermore, the hair wax has good stability in production, especially good high temperature stability, and stable production batches.

[0011] As a preferred embodiment of the hair wax of the present invention, the total weight percentage of the sodium polystyrene sulfonate, ceteareth-25 and ceteareth-30 in the hair wax is 31-33%.

[0012] The present invention has found through experiments that the compounding of sodium polystyrene sulfonate, cetearyl alcohol polyether-25 and cetearyl alcohol polyether-30 can improve the hair styling effect while having good spreadability and retention effect. At the same time, the hair wax has good stability, can prevent dust from adhering, and does not produce white flakes. The present invention has found that when the weight percentage of the above components in the hair wax exceeds 33%, the spreadability, styling effect and styling retention effect of the hair wax are affected to varying degrees; when the weight percentage of the above components in the hair wax is less than 31%, the stability of the hair wax decreases.

[0013] As a preferred embodiment of the hair wax of the present invention, the weight ratio of the sodium polystyrene sulfonate, ceteareth-25 and ceteareth-30 is (1-3):(15-20):(10-15).

[0014] The present invention has found through experiments that when the weight ratio of sodium polystyrene sulfonate, ceteareth-25 and ceteareth-30 is within the above ratio, the prepared hair wax has better spreadability, setting property and stability.

[0015] As a preferred embodiment of the hair wax of the present invention, the weight ratio of the sodium polystyrene sulfonate, ceteareth-25 and ceteareth-30 is 2:15:15.

[0016] The present invention has found through experiments that under this ratio, the hair wax achieves the best performance in terms of application performance, styling performance, effect retention performance, and heat and cold resistance performance.

[0017] As a preferred embodiment of the hair wax of the present invention, the hair conditioning agent is argania spinosa kernel oil, olive fruit oil and castor oil.

[0018] Argania spinosa kernel oil can improve the nourishing property of the product; olive oil is mainly composed of lignans, flavonoids and secoiridoids, which can promote hair growth; castor oil is a grease containing a large amount of hydroxyl groups and has moisturizing properties. Based on the hair wax, adding the above ingredients can further increase the water retention, nourishing property, spreadability and shelf life of the hair wax of the present invention.

[0019] As a preferred embodiment of the hair wax of the present invention, the weight ratio of the argania spinosa kernel oil, olive fruit oil and castor oil is argania spinosa kernel oil:olive fruit oil:castor oil=1:1:1.

[0020] The hair wax prepared with a specific ratio of argania spinosa kernel oil, olive fruit oil and castor oil can significantly improve the gloss of hair, make hair soft and smooth, alleviate the splitting and tangle of dry hair, and make the hair styling effect more beautiful. Furthermore, the solidification point of argania spinosa kernel oil is minus 12°C; the solidification point of olive fruit oil is 0°C; the solidification point of castor oil is minus 10°C; the hair wax prepared with a specific ratio of argania spinosa kernel oil, olive fruit oil and castor oil has good cold resistance.

[0021] As a preferred embodiment of the hair wax of the present invention, the hair wax further comprises the following components: a moisturizer, an emollient, a solubilizer, a fragrance, a preservative and a chelating agent.

[0022] Further preferably, the moisturizer is glycerin and propylene glycol; the emollient is PEG-7 glyceryl cocoate; the solubilizer is hydrogenated castor oil; the fragrance is essence; the preservative is phenoxyethanol, methylparaben and chlorphenesin; and the chelating agent is disodium EDTA.

[0023] PEG-7 glyceryl cocoate is a hydrophilic emollient ester obtained by reacting natural oils and ethylene oxide, which can maintain the oil balance of skin and hair, reduce dryness, and increase the lubrication of skin and hair; the main function of the essence is to cover the smell of the raw materials and give the product a pleasant sensory experience. Phenoxyethanol, methylparaben and chlorphenesin have bactericidal and preservative effects and are used to extend the shelf life of the hair wax of the present invention. Disodium EDTA is mainly used to chelate metal ions and maintain the stability of the hair wax.

[0024] In a second aspect of the present invention, the present invention also provides a method for preparing the above-mentioned hair wax, comprising the following steps:

[0025] (a) mixing methylparaben, disodium EDTA, chlorphenesin, sodium polystyrene sulfonate and water, and stirring to obtain a mixture A;

[0026] (b) mixing ceteareth-25, ceteareth-30, glycerin, PEG-7 glyceryl cocoate, and propylene glycol, and stirring to obtain a mixture B;

[0027] (c) adding mixture B into mixture A to obtain mixture C;

[0028] (d) adding hydrogenated castor oil, argania spinosa kernel oil, olive oil and castor oil to mixture C and stirring to obtain mixture D;

[0029] (e) adding essence and phenoxyethanol to the mixture D, and stirring evenly to obtain the hair wax.

[0030] The preparation method of the hair wax of the invention has simple operation, simple steps, low requirements on equipment, and can realize industrial production.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The hair wax of the present invention has good spreadability, excellent styling effect and shape retention effect, and excellent stability, can conduct away static electricity in hair, prevent dust from adhering, and does not produce white flakes.

[0033] (2) The hair wax of the present invention can keep hair beautiful, shiny and non-greasy, and has excellent heat and cold resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0058]

[0059] Test Example 1 Comprehensive performance test of hair wax.

[0060] 1. Test method for hair wax applicability, styling effect, and holding effect: Wash the 3D hair bundle with a standard shampoo and then rinse until no shampoo and other residues remain. Allow the hair bundle to dry at room temperature. Apply 1.0 g of the hair wax described in Examples 1 to 3 and Comparative Examples 1 to 9 evenly on 8 g of dry hair bundle. Ten trained panelists evaluate the applicability by giving a score for the ease of applying the corresponding hair wax to the hair. The easier it is to apply, the higher the score the corresponding hair wax gets. The styling effect is evaluated by giving a score for the ease of making the hair stand up (from a horizontal position to an upright position). The easier it is to make the hair stand up, the higher the score the corresponding hair wax gets. The holding effect is evaluated by determining how long the style of the hair bundle lasts. The longer the time, the higher the score the corresponding hair wax gets.

[0061] 2. Testing method for the smoothing effect of hair wax: Use the friction performance testing module of the hair multifunctional testing system MTT175 to test the surface friction of the hair bundle using the hair wax of the present invention. The smaller the surface friction of the hair bundle, the smoother the hair bundle.

[0062] 3. Test method for hair wax stability: Place the hair wax in a constant temperature insulation box, heat resistance (45±2℃): 2 months, return to room temperature, check if the hair wax is abnormal; Place the hair wax in a constant temperature insulation box, cold resistance (-18±2℃): 2 months, return to room temperature, check if the hair wax is abnormal; Place the hair wax in a constant temperature insulation box, cycle test (45℃, room temperature, -18℃): one week is one cycle, 3 cycles, check if the hair wax is abnormal. The hair bundle performance scoring standard is shown in Table 3.

[0063] Table 3 Performance scoring criteria for hair wax

[0064]

[0065] The performance test results of the hair wax are shown in Table 4:

[0066] Table 4 Performance test results of hair wax

[0067]

[0068] As shown in Table 4 and Figure 1 As shown, the test results show that the hair wax prepared in Examples 1 to 3 of the present invention has excellent spreadability, styling effect, styling retention effect, smoothing effect and stability.

[0069] The present invention has found in experiments that adding cetearyl alcohol polyether-30 to hair wax has good formula stability and shaping effect, but because the melting point of cetearyl alcohol polyether-30 is higher than that of cetearyl alcohol polyether-25, it needs to be filled at 80°C-85°C in actual production. Below this temperature, condensation will occur and filling is impossible, but a large number of PET bottles will deform at this filling temperature, so it does not meet the actual production requirements; adding cetearyl alcohol polyether-30 to hair wax can enhance the stability of the product, but the present invention has found in experiments that excessive addition of cetearyl alcohol polyether-30 (Comparative Examples 1 to 2) leads to poor spreadability of the hair wax, low softness of the hair bundle, and it is not easy to spread and use during use, resulting in an extremely poor user experience, and thus is not suitable for market sales requirements.

[0070] The hair wax prepared in Comparative Example 3 of the present invention, to which excessive amounts of sodium polystyrene sulfonate and cetearyl alcohol polyether-25 are added, has good spreading performance, but the hair wax has poor heat resistance and poor stability.

[0071] The hair wax prepared in Comparative Example 4 of the present invention does not add sodium polystyrene sulfonate, and Comparative Example 5 only adds a small amount of sodium polystyrene sulfonate, and the spreadability, styling effect and retention effect of the hair wax are all reduced. The hair wax prepared in Comparative Example 7 does not add ceteareth-30, and the styling retention effect of the hair wax is reduced, and its stability is reduced. The hair wax prepared in Comparative Example 8 does not add ceteareth-25, and the hair wax has high hardness and poor spreadability. This further proves that sodium polystyrene sulfonate, ceteareth-30 and ceteareth-25 have a synergistic effect, which can synergistically improve the spreadability, styling effect, styling retention effect and stability of the hair wax.

[0072] Comparative Example 6 of the present invention adds a relatively small amount of ceteareth-25, and the contents of sodium polystyrene sulfonate, ceteareth-25 and ceteareth-30 contained therein are less than 31% (the content accounts for only 28%), and the setting effect, styling effect and stability of the prepared hair wax are all reduced.

[0073] The hair wax prepared in Comparative Example 9 of the present invention adds more olive oil, and its cold resistance is reduced, and the styling effect is also reduced.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
