Description

Technical Field

[0001] The invention belongs to the technical field of daily chemicals, and particularly relates to a high-efficiency repairing and conditioning hair additive based on a self-emulsifying amino group and a preparation method thereof. Background Art

[0002] Hair is often damaged by a variety of factors, including rinsing, drying, heating, combing, styling, perming, dyeing, and exposure to the elements, as follows:

[0003] 1) Chemical damage (e.g. from detergents, bleaching, straightening, dyeing and permanent waving), heat (e.g. from hair dryers and curling irons) and mechanical stress or abrasion;

[0004] 2) Due to malnutrition of hair roots and hair, hair roots become blocked, which affects the nutrition of hair follicles, causing them to shrink and be destroyed. As a result, hair gradually becomes thinner, dry, or even brittle and falls off. In addition, fine and soft hair can easily cause hair to become limp, leading to a decrease in hair volume.

[0005] 3) As the hair length increases, its hair scale cells partially fall off, the hair becomes less flexible and easily twisted, causing the hair to easily become tangled and break during combing and washing.

[0006] In order to solve the above problems, the common practice is to rely on hair care products for conditioning hair, especially to give hair excellent smoothness, glossiness, softness, flexibility, brightness, natural feeling and good unwinding characteristics. Commonly used hair care products include hair conditioner, hair cream, hair mask, hair mask or hair essence, etc. These products are mainly prepared by compounding ingredients such as cationic surfactants, silicone oil and other auxiliaries, and give hair gloss and glossiness. They can be used on hair after shampooing or rinsing hair, so as to give hair care properties, and are usually rinse-type products that need to be cleaned. In recent years, people's demand for high-end hair care products has become stronger. In the face of increasingly fierce market competition, providing people with more excellent products has become a problem that all manufacturers must face. In the case of limited improvement space for the matrix raw materials of hair care products, it is particularly important to develop new conditioning additives or improve the quality of existing conditioning additives.

[0007] As for the silicone oil used in hair care products, silicone oil is an organic siloxane, which is a general term for dimethylsiloxane, cyclodimethylsiloxane or its derivatives. It is the most commonly used hair care additive. It generally needs to be emulsified before being added to hair care products. It is used to improve the conditioning and antistatic ability of hair. It can effectively improve the combing performance of hair, reduce friction, reduce the difficulty of combing, and make hair smooth, shiny and elastic. Silicone oil hair additives can be roughly divided into three categories: the first category is polydimethylsiloxane, which can improve the brightness and dispersion of hair, but the softness is poor. Due to its poor water solubility, a large amount of surfactant needs to be added for emulsification; the second category is hydroxyl-containing polydimethylsiloxane, which can improve the slippery feeling after emulsification, but the adhesion is poor and the softness is not ideal; the third category is amino-modified polydimethylsiloxane, which can improve the softness of hair, but the brightening and slippery feeling improvement effect is not ideal. There are also hair additive products on the market that use several types of silicone oils at the same time, but the compounding requirements for product emulsification are high, and demulsification phenomena such as flocculation and stratification are prone to occur.

[0008] In order to improve the hair conditioning effect, in the research of using silicone oil as a hair care additive, the related art discloses some means, such as Chinese patent CN102138882A uses behenyl trimethyl ammonium chloride and the like as a cationic surfactant, silicone oil conditioning, panthenol and the like as moisturizing agents, but such compositions have limited moisturizing properties and are prone to irritating the scalp, causing itching and flaking of the hair. Chinese patent CN1098901A proposes to use non-volatile silicone fluid, non-volatile extender and suitable carrier to compound a hair care composition, but it is found that long-term use of such a composition will easily cause excessive deposition of silicone and other ingredients on the hair, making the hair more greasy, easy to get dirty, and poorly conditioned. Chinese patent CN105267063A discloses a silicone oil product, but the technical solution cannot achieve uniform and effective conditioning and enrichment on the entire hair, and only deposits a large amount of it at the end of the hair, further making the hair overburdened and close to the scalp, which is not conducive to hair health. Chinese patent CN106176467B neutralizes the negative charge on the hair by adding cationic surfactants or conditioning agents during use, but these surfactants are washed away in large quantities after use and rarely accumulate effectively on the hair, thus failing to achieve a long-lasting conditioning effect.

[0009] In summary, it is of great significance to develop an efficient repairing hair care additive with high comprehensive performance. Summary of the invention

[0010] In view of this, the present invention provides a highly effective hair repairing and conditioning additive based on self-emulsifying amino silicone oil and a preparation method thereof in order to solve the above problems.

[0121] Application Examples

[0122] Provided is a hair mask liquid, the raw materials and the proportions thereof are as follows:

[0123] The hair care additives obtained in the above Examples 1-4 and Comparative Examples 1-10 are directly added to the basic formula of the hair mask liquid in an amount accounting for 2% by mass of the hair mask liquid, to obtain the hair mask liquid provided by the formulas described in Application Examples 1-4 and Comparative Application Examples 1-10; wherein the basic formula of the hair mask liquid includes 0.03% of disodium ethylenediaminetetraacetate, 0.2% of phenoxyethanol, 0.3% of 2,6-di-tert-butyl-4-methylphenol, 0.7% of ethylene glycol distearate, 4% of panthenol, 0.05% of sodium citrate, 0.5% of essence and deionized water; the sum of the basic formula amount of the hair mask liquid and the amount of the hair care additives is 100% by mass.

[0124] The preparation of the hair mask liquid is as follows:

[0125] ① Mix disodium ethylenediaminetetraacetate, sodium citrate, 2,6-di-tert-butyl-4-methylphenol with deionized water according to the formula, heat to 75°C and stir thoroughly until evenly dispersed;

[0126] ②Then cool down to 60℃, add hair care additives according to the formula, and stir until evenly dispersed;

[0127] ③Then cool down to 45℃, add phenoxyethanol, ethylene glycol distearate and panthenol according to the formula and continue to stir evenly, then cool down to 40℃, add essence according to the formula and continue to stir evenly to get the hair mask liquid.

[0128] The hair mask is preferably applied on wet hair, and the specific steps of use are as follows:

[0129] (A) Clean your hair with an appropriate amount of shampoo;

[0130] (B) applying an effective amount of hair mask liquid on the hair for 5-10 minutes, wherein the effective dose is usually in the range of 1-30 g, preferably 5-20 g;

[0131] (C) rinsing the hair mask liquid on the hair with water.

[0132] Test Case

[0133] The hair masks prepared with the hair care additives described in Examples 1-4 and Comparative Examples 1-10 were subjected to performance tests, including stability tests, demulsification speed tests and a series of functional tests.

[0134] 1. Stability test: The hair mask liquid of the above formula is stored under predetermined conditions for stability test. After the material is taken out and returned to room temperature, its appearance is observed and compared with that at room temperature. For specific conditions and results, see Table 1.

[0135] Table 1: Hair mask stability test results.

[0136]

[0137]

[0138] Note: “-” indicates no change; the hot and cold cycle test condition is to cycle once every 24 hours at -20℃ and 45℃.

[0139] As can be seen from Table 1, the compounding of amino-modified polydimethylsiloxane, polyquaternium-modified polyethylene glycol-19-polypropylene glycol-19-polydimethylsiloxane, polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer and cyclopentasiloxane is beneficial for the prepared hair mask to have improved stability at both low and high temperatures.

[0140] 2. Demulsification speed test:

[0141] At 25°C, 10g, 5g, 4g, 3g, 2g, and 1g of the hair mask solution of the above formula were accurately weighed in a 150ml beaker, and 100ml of deionized water was added. After stirring for 1 minute at a stirring speed of 60rpm / min, the mixture was allowed to stand and the state of the substance in the beaker was observed. The results are shown in Table 2:

[0142] Table 2: Hair mask demulsification speed test results.

[0143]

[0144] As can be seen from Table 3, the silicone oil in the hair mask liquid added with the hair care additive of the present invention can be demulsified when diluted 10 times, while the shampoos provided in Comparative Application Examples 5 and 6 basically need to be diluted 100 times before the silicone oil can be demulsified. This shows that the present invention uses specific types of high molecular surfactants and small molecule surfactants for compounding, which can accelerate the improvement speed of silicone oil.

[0145] 3. Functional testing

[0146] Test subjects: A certain number of damaged hair bundles (50cm long, 25g in weight; some of which were dyed using a unified process) were first washed with standard shampoo (2g), wiped with a towel until water did not leak, and then the hair mask (5g) provided by the above formula was applied to the hair evenly. After standing for 15 minutes, the hair was washed and blown dry. After 48 hours, the previous steps were repeated 4 times, and the hair was washed after the fifth use of the hair mask and set aside.

[0147] 3.1 Friction coefficient test

[0148] The wet friction coefficient of the hair bundle was tested using a Dia-Stron MTT friction coefficient tester. The hair bundle was then blow-dried and the dry friction coefficient of the hair bundle was tested, taking the average of three valid parallel measurement readings. The smaller the friction coefficient, the smoother the hair, and the better the combing effect and conditioning of the hair mask. The test results are shown in Table 3.

[0149] Table 3: Hair bundle friction coefficient test results.

[0150]

[0151] 3.2 Contact angle test

[0152] The contact angle measuring instrument is used to measure the contact angle of the hair bundle surface of the hair mask night care. The contact angle reflects the hydrophobicity of the hair, and hydrophobic wet hair damage sign. The contact angle increases, the hydrophobicity decreases, and the hair is repaired; the contact angle decreases, the hydrophobicity increases, and the hair is damaged. The test results are shown in Table 4:

[0153] Table 4: Hair strand contact angle test results.

[0154]

[0155] The results showed that the contact angle of hair using the hair mask of the present invention was significantly increased, the hydrophobicity was enhanced, and the hair surface scales were significantly repaired.

[0156] 3.3 Antistatic test: The hair bundles were treated with the hair mask provided by the above formula for 5 times, then washed and dried, and then the potential of the hair bundles was measured by a vibration capacitance type potentiometer. The test results are shown in Table 5;

[0157] 3.4 Combing effect test: After the hair bundles were treated with the hair mask provided by the above formula for 5 times, the resistance encountered during combing the hair was measured by a micro tensile tester in dry and wet states to judge the combing performance of the hair. The test results are shown in

[0158] Table 5: Antistatic and combing effect test results.

[0159]

[0160] It can be seen from Table 5 that the use of the functional additive of the present invention is more conducive to improving the antistatic property and combing performance of the hair bundle.

[0161] 3.5 Hair bundle tensile strength (toughness) test: Using an INSTRON tensile tester, the tensile strength A0 of the hair was measured after the hair bundle was washed for the first time. After the hair mask was used for the fifth time and the hair was washed and dried, the tensile strength A5 of the hair was measured, and the tensile strength change rate δ = 100% × (A5-A0) / A0 was calculated. The test results are shown in Table 6.

[0162] Table 6: Hair bundle toughness test results.

[0163]

[0164]

[0165] It can be seen from Table 6 that the use of the surfactant described in the present invention can further enhance the toughness of the hair bundle.

[0166] 3.6 Fading experiment: After the dyed hair bundles were treated with the hair mask provided by the above formula for 5 times and then washed and blown dry, the fading experiment of permanent hair dyeing was tested using an X-rite colorimeter to compare the color difference of the dyed hair bundles after the hair mask provided by the above formula was used for night care, represented by the color difference symbol ΔE. The larger the ΔE value, the greater the color difference and the lower the color protection. The color protection test results are shown in Table 7.

[0167] Table 7: Color protection test results.

[0168]

[0169] As can be seen from Table 7, the use of the surfactants described in the present invention is more conducive to imparting improved color protection to hair strands.

[0170] 3.7 Evaluation of the effect of imparting moisture to hair and the durability of moisture: Immediately after the fifth use of the hair mask and washing and drying, and 6 hours later, the maximum reflection amount of light based on the light irradiation angle (-45°C to +45°C) was measured using a SAMBA instrument, and the measured value was expressed as the moisture of the hair bundle in %. The test results are shown in Table 8.

[0171] Table 8: Effect of imparting moisturizing property to hair and test results of moisturizing property durability.

[0172]

[0173] It can be seen from Table 8 that the use of the functional additives of the present invention is more conducive to imparting moisturizing and lasting moisturizing effect to hair.

[0174] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
