Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and particularly relates to a strong styling hairspray composition, a preparation method thereof, and an application thereof. Background Art

[0002] As a common hair styling product, hairspray is widely used in daily life for shaping and fixing hairstyles. Its main function is to form a uniform thin film on the hair surface through a film-forming substance, thereby achieving hair styling, smoothness, and gloss. With the continuous improvement of consumers' requirements for hairstyle durability and natural texture, the market demand for strong styling hairspray continues to grow. Traditional strong styling hairspray usually uses acrylate copolymers and vinyl pyrrolidone polymers as the main film-forming agents, and forms a rigid thin film on the hair surface through solvent evaporation to achieve styling. However, there are many deficiencies in the prior art in terms of formulation design and preparation process, and it is difficult to simultaneously meet the comprehensive requirements of high-strength styling, hair softness, environmental adaptability, and safety.

[0003] Short lasting styling time: Traditional hairspray compositions usually use polyurethane acrylate as the main film-forming substance, but the film-forming performance of a single component is limited, and it is easy to soften or break the film layer in a humid and hot environment, resulting in a rapid attenuation of the styling effect. Especially under high temperature and high humidity conditions, the lasting time of the hairspray is significantly shortened, and it cannot meet the needs of consumers for long-term styling.

[0004] Lack of softness: Traditional hairspray relies on film-forming agents with high glass transition temperatures to obtain strong styling effects, but the films formed by such components have poor flexibility, which easily causes the hair to be stiff, lack natural luster, and the film layer is prone to brittle fracture in a low-temperature environment, resulting in a decline in the anti-extrusion performance of the hairstyle. At the same time, the binding force between ordinary cationic conditioners and hair strands is insufficient, the hairspray is easy to fall off, and the styling effect is significantly attenuated after multiple combs.

[0005] White flake residue problem: Some hairspray products will leave white flakes on the hair after use. The main reason is that the film-forming substance precipitates unevenly under humid and hot conditions, forming tiny inorganic particles or unreacted solid substances. This not only affects the appearance but also may pose a potential threat to scalp health. Summary of the Invention

[0006] In view of this, the present invention provides a strong styling hairspray composition, a preparation method thereof, and an application thereof to solve the above problems.

[0007] The technical solution of the present invention is realized as follows: A strong styling hairspray composition: It contains components in the following mass percentages: 15-22% of polyurethane acrylate, 5-12% of nano-aluminum oxide sol, 3-7% of polysiloxane-modified cationic cellulose, 4-8% of enhancer stable dispersion liquid, 2-5% of natural polysaccharide modifier, 18-20% of solvent, and the balance is deionized water; the particle size of the nano-aluminum oxide sol is 10-30 nm, and the alumina content in the sol is 8-15 wt%.

[0008] Further, the polysiloxane-modified cationic cellulose is prepared by mixing hydroxyethyl cellulose with a sodium hydroxide solution with a mass concentration of 5-8% at a mass ratio of 1:8-10, swelling for 20-40 min, adding 3-aminopropyltriethoxysilane (KH550), controlling the amount of silane used so that the final product has a silicon content of 5-10%, reacting in a water bath at 50-70 °C for 3-5 hours, and after the reaction is completed, precipitating and purifying with ethanol and drying in vacuum for standby.

[0009] Further, the enhancer stable dispersion liquid is prepared by mixing hydroxyapatite nanowires and graphene oxide sheets at a mass ratio of 3-5:1, ultrasonically dispersing them in ethanol with a volume 1-3 times that of the mixture, with an ultrasonic power of 200-400 W and a time of 30-60 min to form a uniform dispersion liquid. The diameter of the hydroxyapatite nanowires is 5-20 nm, the aspect ratio is ≥50, and the number of layers of the graphene oxide sheets is ≤5.

[0010] Further, the natural polysaccharide modifier is prepared by dissolving xanthan gum in deionized water to form a 3-5 wt% solution, adding acrylate, purging with nitrogen to remove oxygen, reacting at 60-80 °C for 2-4 hours, controlling the grafting rate at 40-60%, centrifuging at high speed to remove unreacted monomers, and freeze-drying to obtain the modified product.

[0011] Further, the solvent is a mixture of polyglycerol-6 distearate and propylene glycol methyl ether acetate with a mass-to-volume ratio of g / mL of 3-5:10.

[0012] Further, a preparation method of a strong styling hairspray composition includes the following steps:

[0013] S1. Heat and stir the solvent at 40-60 °C until transparent, add polyurethane acrylate, control the stirring speed at 300-500 rpm, continue for 15-20 min, and slowly drop the nano-aluminum oxide sol under nitrogen protection while stirring to form a premixed liquid;

[0014] S2. Sequentially add polysiloxane-modified cationic cellulose and natural polysaccharide modifier to the premixed liquid, stir at 40-50 °C at 200-300 rpm for 20-30 min to ensure uniform dispersion, continue to add the enhancer stable dispersion liquid, and perform ultrasonic treatment for 10-15 minutes to prevent the settlement of nano materials;

[0015] S3. Slowly add deionized water to make the total system volume reach 100%, perform homogenization treatment, adjust the pH to 5.5 - 6.5 at room temperature after cooling, and sterilize and subpackage through a 0.20 - 0.30 μm filter membrane.

[0016] Furthermore, in step S1, the dropping rate is 1 - 2 mL / min, the stirring speed is 100 - 300 rpm, and the stirring is carried out for 8 - 15 min.

[0017] Furthermore, in step S2, the ultrasonic power is 200 - 400 W, and the ultrasonic frequency is 30 - 50 kHz.

[0018] Furthermore, in step S3, the homogenization pressure is 60 - 80 MPa, the feeding temperature is 35 - 40 °C, the discharging temperature is ≤ 45 °C, and it is circulated 3 - 5 times, with each time being 2 - 8 min.

[0019] Furthermore, the strong - setting hairspray composition is used for hairstyle setting in high - temperature and high - humidity environments, the setting duration is ≥ 8 hours, and the hair bundle tensile strength is ≥ 12 N / cm 2 。

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The present invention provides a hairspray composition with high - strength setting, natural and smooth texture, excellent environmental adaptability and safety through formula design and optimized preparation process, significantly improving the comprehensive performance of the hairspray, and solving the pain points of traditional hairsprays such as setting failure in humid and hot environments, white dandruff residue, and stiff hair.

[0022] Among them, polyurethane acrylate is used as the core film - forming agent, and nano - alumina sol is introduced to enhance the hardness and toughness of the film, effectively extending the setting duration. Polysiloxane - modified cationic cellulose and polyurethane acrylate jointly form a flexible film - forming network, improving the elasticity and anti - fracture performance of the hairspray, reducing the hair friction coefficient, and preventing frizzy hair. The enhanced properties of hydroxyapatite nanowires and graphene oxide sheets in the stabilizer dispersion liquid can be evenly dispersed, intertwined and synergistically interact with other components. The natural polysaccharide modifier obtained by grafting acrylate onto xanthan gum can form a hydrophilic and smooth protective film on the hair surface, significantly improving the hair smoothness, reducing the friction between hair strands, and making the hair maintain a natural hanging texture and smooth touch after setting.

[0023] In the preparation method, temperature control and stirring are carried out to fully dissolve the solvent and polyurethane acrylate to form a homogeneous system. Under nitrogen protection, nano-aluminum oxide sol is slowly added dropwise and stirring is continuously carried out to prevent agglomeration of nanoparticles, so as to achieve uniform dispersion of nano-components and release of enhanced efficacy. At an appropriate temperature and through a reasonable stirring speed, modified cellulose and natural polysaccharides are uniformly dispersed. After adding an enhancer, ultrasonic treatment is carried out to strengthen the dispersion of nano-materials, avoid sedimentation, and ensure the uniform and stable performance of the product. High-pressure homogenization treatment realizes deep mixing of components, precisely controls pressure, temperature and circulation parameters to form a stable colloid, adjusts the pH and sterilizes and sub-packages through a filter membrane to ensure the stable storage of the product and meet safety standards. The formula of the present invention has excellent practical value and promotion prospects, and can meet the needs of consumers for high-efficiency, safe and environmentally friendly hairspray products.

Stretch it at a speed of 100 mm / min until it breaks, record the maximum tensile force value, and calculate the tensile strength (unit: N / mm 2 )

[0079] (2) Binding force with hair strands: Using the tape peeling method: Apply hairspray on the surface of the hair bundle, after drying, attach a standard tape, and quickly peel it at a 90° angle, record the force value during the peeling process (unit: N). Repeat 5 times and take the average value.

[0080] (3) Surface friction coefficient test: Using a friction tester, apply hairspray on the surface of the hair strands, and measure the sliding friction coefficient between the hair strands and other materials (glass plate). The test speed is 10 mm / s, the load is 100 g, repeat 5 times and take the average value.

If the hair bending degree changes by more than 30% and the looseness of the hair bundle increases by more than 50%, it is regarded as the styling failure, and record the time at this moment as the styling duration.

[0087] (2) Softness test: Comb the styled hair bundle from the root to the tip with a standard comb, record the hair breakage situation and combing resistance, and score according to 1 - 5 points (5 points is the smoothest).

[0091] III. Stability test

[0092] (1) Humid heat styling retention rate: Place the styled hair bundle in an environment of 40°C and RH85% for 2 hours, then measure the deformation degree of the hair bundle and calculate the styling retention rate;

[0093] Humid heat styling retention rate (%) = (Length after styling - Length after deformation) / Length after styling × 100%.

[0094] (2) White residue test: Observe whether there is white residue on the hair surface under the simulated humid and hot environment (40 °C / 85% RH).

[0098] The results in the above Tables 1 - 3 show that the nano-aluminum oxide sol, polysiloxane-modified cationic cellulose, enhancer stable dispersion, and natural polysaccharide modifier in the formulation of the present invention have significant synergistic effects, improving the uniformity and stability of film formation. The introduction of nano-aluminum oxide sol acts synergistically with polyurethane acrylate to enhance the setting strength through the hard segment benzene ring structure, and the soft segment polyethylene glycol chain segment improves the flexibility. The enhanced stabilizer dispersion can be evenly dispersed, improving the lubricity and flexibility of the hairspray. The polysiloxane-modified cellulose reduces the combing resistance and improves the flexibility through cation adsorption and siloxane lubrication. The natural polysaccharide modifier adjusts the rheological properties to achieve a balance between strength and flexibility. The polysiloxane-modified cationic cellulose reduces the friction damage and white residue generation on the hair surface through lubrication and film formation.
