Description

Technical Field

[0001] The invention belongs to the field of daily chemicals, and particularly relates to a hair care composition containing tomato seed oil. Background Art

[0002] According to the "2023 National Scalp Care Consumption White Paper", there are three main scalp problems commonly encountered by consumers: greasy, hair loss, and dryness. Although the oil secreted by the scalp can moisturize the hair, if the secretion is too much, it is easy to induce dandruff, dermatitis, and even hair loss. When using shampoo products to clean the scalp, excessive cleaning, incomplete cleaning resulting in surfactant residues on the scalp, or scratching hard may aggravate scalp problems and disrupt the balance of scalp microorganisms. In addition, daily perming and dyeing, ultraviolet rays, and air pollutants can easily cause hair damage, causing the protein in the hair to decompose and nutrients to be lost, resulting in rough, yellow, dry, dull, lack of elasticity, and even easy to break. These injuries may also indirectly affect the health of the scalp. Therefore, more and more consumers prefer hair care products that can solve scalp health problems such as dandruff, strong oil secretion, severe hair loss, and dry, frizzy, and yellow hair. Currently, hair care products on the market usually use dimethicone to make hair smooth and shiny, but long-term use may cause silicone oil to deposit on the hair, forming a thick oil film, making the hair greasy and the effect poor.

[0003] Therefore, there is an urgent need to develop a hair care product containing active ingredients of plant origin, which can not only solve the problems of dullness, dryness, hardness and brittleness, split ends and breakage, frizziness and easy breakage caused by damage and oxidation of hair, achieve the effect of smoothing hair, but also give hair better conditioning, improve hair quality and enhance hair gloss. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a hair care composition containing tomato seed oil. The hair care composition of the present invention can well improve the dry and wet combing properties of hair, increase the glossiness of hair, reduce the friction of hair, and improve the antistatic force of hair, while greatly reducing the irritation to the scalp, and has a good moisturizing and nourishing effect and a good use experience.

[0005] The technical solution adopted by the present invention to solve the above problems is as follows:

[0006] A hair care composition containing tomato seed oil comprises the following raw materials in percentage by mass: 2% to 10% tomato seed oil; 0.5% to 5% quaternized wheat protein; 1% to 10% higher fatty alcohol; 0.1% to 8% cationic conditioner; 1% to 10% moisturizer; and the balance of deionized water.

[0007] Preferably, the hair care composition comprises the following raw materials in percentage by mass: 2% to 10% tomato seed oil; 0.5% to 4% quaternized wheat protein; 1% to 8% higher fatty alcohol; 0.1% to 5% cationic conditioning agent; 1% to 8% moisturizing agent; and the balance of deionized water.

[0008] More preferably, the hair care composition comprises the following raw materials in percentage by mass: 2% to 5% tomato seed oil; 0.5% to 1.5% quaternized wheat protein; 1% to 8% higher fatty alcohol; 0.1% to 3% cationic conditioner; 1% to 5% moisturizer; and the balance deionized water.

[0009] Furthermore, the preparation method of the tomato seed oil comprises the following steps:

[0010] S1. Wash and dry the tomato seeds, and crush the dried tomato seeds into 20-80 mesh;

[0011] S2. Adding an entrainer to the crushed tomato seeds in step S1 and subjecting them to supercritical CO2 extraction to obtain tomato seed oil;

[0012] S3. Decolorizing the tomato seed oil obtained in step S2;

[0013] S4. Filter the decolorized tomato seed oil.

[0014] Furthermore, the tomato seeds can be collected from tomato paste processing waste. Collecting tomato seeds from tomato paste processing waste and extracting tomato seed oil can effectively reduce the waste of tomato paste processing waste and the pollution to the environment.

[0015] Furthermore, the drying temperature is 75° C. to 95° C., and the drying time is 10 to 15 minutes.

[0016] Furthermore, the temperature of the supercritical carbon dioxide extraction is 50±2°C, the extraction pressure is 40MPa-50MPa, the extraction time is 1h-3h, the flow rate of CO2 is 15-35kg / h, and the flow rate of the entrainer is 1.5±0.55kg / h.

[0017] Furthermore, the entrainer is anhydrous ethanol.

[0018] Furthermore, the decolorization treatment is to stir and mix the tomato seed oil and activated carbon in a mass ratio of 800:1-2 to evenly perform decolorization.

[0019] Furthermore, the activated carbon is 50 mesh activated carbon.

[0020] Furthermore, the decolorization temperature is 75±5° C., the decolorization vacuum degree is 0.08±0.02 MPa, and the decolorization time is 25 min to 30 min.

[0021] Furthermore, the filtration can be performed using a filter machine, which uses a 200-mesh filter cloth and controls the pressure to 0.5 MPa.

[0022] Furthermore, the higher fatty alcohol is one or more of lauryl alcohol, tetradecanol, hexadecanol, 16-octadecanol, and stearyl alcohol. Preferably, the higher fatty alcohol is hexadecanol and 16-octadecanol. The higher fatty alcohol selected by the present invention has good smearing ductility and adheres to the hair to enhance the gloss and smoothness of the hair, so that the hair can be well nourished and smooth.

[0023] Further, the cationic conditioning agent is one or more of cetrimonium chloride, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium methyl sulfate, stearyl trimethyl ammonium methyl sulfate, and quaternary ammonium salt 80. First, the cationic conditioning agent selected in the present invention can react with the static charge on the surface of the hair, reduce the electrostatic repulsion between the hair, make the hair smoother, and effectively reduce the frizziness and tangling problems; secondly, the cationic conditioning agent selected in the present invention can form a thin film on the surface of the hair, increase the adhesion of other hair care ingredients on the hair, and enhance the durability of the hair care effect. The cationic conditioning agent selected in the present invention has an excellent conditioning effect, has static elimination, soft moisturizing and conditioning effects, and can greatly improve the combing and hair quality of the hair.

[0024] Furthermore, the moisturizing agent is one or more of polyol, trehalose, saccharide isomers, PPG-3 benzyl ether myristate, and sodium DL-pyrrolidonecarboxylate.

[0025] Preferably, the moisturizer is polyol and PPG-3 benzyl ether myristate.

[0026] Furthermore, the polyol is at least one of glycerol, sorbitol and 1,3-butanediol.

[0027] The moisturizer selected in the present invention can increase the moisturizing effect of the hair, effectively maintain the water-oil balance of the hair, ensure that the hair remains moisturized and humidified for a long time, thereby reducing the problem of hair fragility, breakage and tangling caused by dryness; at the same time, it can also reduce the electrostatic repulsion phenomenon caused by dryness, enhance the softness of the hair, and make the hair smoother and easier to manage.

[0028] Furthermore, the hair care composition may also include at least one of the following raw materials: a fragrance agent, a chelating agent, an appearance modifier, a preservative, and a pH adjuster.

[0029] The present invention has the following beneficial effects:

[0030] The tomato seed oil extracted by the invention is rich in biologically active ingredients such as tocopherol and phytosterol, and can be used in hair care products to improve hair quality. The quaternized wheat protein of the invention has a similar molecular structure to keratin in human hair, and can effectively bond broken molecules, rebuild the spatial configuration, and fill the defects of hair. After the wheat protein is quaternized, the replaced amino group retains cationicity, and can be combined with the negative charge of damaged hair, and the positive charge of the protein is doubled, which has a protective effect on hair and hair, effectively protects damaged hair, strengthens hair, and restores the luster of hair.

[0031] The present invention applies tomato seed oil and quaternized wheat protein to a hair care composition containing a higher fatty alcohol, a cationic conditioning agent, and a moisturizer to achieve synergistic effects, and can solve the problems of dullness, dryness, hardening and brittleness, split ends and breakage, frizziness, and easy breakage of hair caused by damage and oxidation. The hair care composition of the present invention can well improve the dry and wet combing properties of hair, repair damaged hair, increase the glossiness of hair, reduce the friction of hair, and improve the antistatic force of hair. At the same time, it greatly reduces the irritation to the scalp, creates a good microecological environment of the scalp with a water-oil balance, and has a good moisturizing and nourishing effect and a good use experience.

[0053] The preparation method of the comparative hair care composition can be obtained in the same manner.

[0054] The hair care compositions prepared in the above examples and comparative examples were subjected to laboratory instrument efficacy evaluation and consumer sensory evaluation. The evaluation results are shown in Table 2.

[0055] Table 2:

[0056]

[0057]

[0058] From the evaluation results in Table 2, it can be seen that compared with the hair care compositions of Comparative Examples 1 to 3 without adding tomato seed oil and / or quaternized wheat protein, the hair care compositions of Examples 1 to 3 with added tomato seed oil and quaternized wheat protein can well improve the wet and dry combing properties of hair, increase the glossiness of hair, reduce the friction of hair, and improve the antistatic force of hair, and have a good moisturizing and nourishing effect and a good use experience.

[0059] Compared with the hair care composition of Example 3, the hair care composition of Comparative Example 4 increases the formula ratio of quaternized wheat protein. Although the dry and wet combing properties and glossiness of the hair are improved to a certain extent, there is still a significant gap compared with the dry and wet combing properties, antistatic ability and glossiness of Example 3. At the same time, the hair care composition of Comparative Example 4 has greater scalp irritation. In summary, the best preferred ratio of the hair care composition of the present invention is 2% to 5% tomato seed oil; 0.5% to 1.5% quaternized wheat protein; 1% to 8% higher fatty alcohol; 0.1% to 3% cationic conditioner; 1% to 5% moisturizer; and the balance of deionized water.

[0060] Compared with the hair care composition of Example 1, the hair care composition of Comparative Example 5 replaces the quaternary aminated wheat protein with hydrolyzed keratin. It can be found that the wet hair combing property, glossiness, friction, antistatic force and moisturizing effects of Comparative Example 5 are not greatly improved. The tomato seed oil and quaternary aminated wheat protein in the hair care composition of the embodiment work synergistically to improve the dry and wet hair combing property, increase the glossiness of the hair, reduce the friction of the hair, and improve the antistatic force of the hair, and have a good moisturizing and nourishing effect and a good use experience.

[0061] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0063] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
