Description

Technical Field

[0001] The present invention relates to the field of cosmetic technology, and in particular to a quick-drying styling spray and a preparation method thereof, in particular to a hair styling product that achieves quick drying, long-lasting styling, and hair care effects through the synergistic effect of a specific film-forming agent and a volatile system. Background Art

[0002] As people's quality of life improves, they increasingly value the aesthetics and durability of their hairstyles. As hair styling products are crucial for shaping and maintaining hairstyles, market demand continues to grow. However, current hair styling sprays on the market suffer from numerous drawbacks.

[0003] In terms of drying speed, many styling sprays take a long time to dry. For example, a standard spray under normal temperature and humidity conditions may take 5-10 minutes to initially dry, significantly impacting efficiency and causing inconvenience for consumers with fast-paced lifestyles. Lack of styling durability is also a common problem. Faced with wind, sweat, and friction from daily activities, most styling sprays struggle to maintain a style for long periods of time. Hair typically becomes noticeably deformed after 2-4 hours, failing to meet consumers' all-day styling needs. Furthermore, some styling sprays can damage hair, leaving it dry, brittle, and lacking luster after prolonged use.

[0004] Traditional styling sprays, in pursuit of quick drying, often contain large amounts of highly volatile organic solvents, such as high-concentration ethanol. While this accelerates drying, it also damages the hair's cuticle, causing moisture loss and leaving it dry and brittle. While some film-forming agents can temporarily set hair, the film they form is too rigid, leaving it stiff and unnatural. Furthermore, due to its lack of flexibility, it easily breaks under external influences, rendering the setting ineffective. Furthermore, existing styling sprays are complex formulas containing multiple chemical ingredients, increasing the risk of allergies and making them unsuitable for those with sensitive scalps.

[0005] Prior art CN107822904A discloses a spray emulsion composition and its preparation method. The spray emulsion composition comprises an oil phase A, an aqueous phase B, a phase C, and a phase D. The oil phase A comprises an oil-soluble emulsifier, an emollient, a grease component, and silicone oil; the aqueous phase B comprises water, an acrylate / beheneth-25 methacrylate copolymer, a water-soluble emulsifier, a humectant, and allantoin; the phase C comprises aminomethyl propanol and triethanolamine; and the phase D comprises phenoxyethanol and parahydroxyacetophenone. The resulting spray emulsion composition can be sprayed with a sprayer to produce a smooth emulsion with a refreshing feel and easy skin absorption. However, this technology does not mention quick-drying and setting effects. Prior art CN113304082A proposes a waxy fluffy styling hair care foam aerosol and its preparation method, comprising a film-forming agent, grease, emulsifier, thickener, humectant, foaming agent, emollient, preservative, triethanolamine, phenoxyethanol, Polygonum multiflorum root extract, kaolin, essence, deionized water and propellant. The invention is compounded with wax raw materials, grease, emulsifier and functional nutritional components, and the mixed propellant is used as an aerosol, which is sprayed and sprayed in a foamy state. The styling effect is natural, and the hair can be given a natural gloss, refreshing, non-sticky and free of white flakes. The film formed on the hair has a certain elasticity, can be repeatedly shaped into different hairstyles, has good curl retention, and has natural, long-lasting and beautiful styling. It has secondary styling ability, nourishes, protects and conditions the hair, and has the functions of moisturizing, nourishing and protecting the hair. This patented technology takes into account both styling and hair care functions, but does not take into account the quick-drying requirements in actual applications.

[0006] In summary, developing a styling spray that dries quickly, has a long-lasting styling effect, is gentle on hair and has safe ingredients has important practical significance and market value. Summary of the Invention

[0007] The present invention aims to solve the technical problem that hair styling products in the prior art cannot achieve both drying speed, styling durability and scalp repair, and provides a quick-drying styling spray and a preparation method thereof.

[0008] In order to solve the above technical problems, this application designs the following component system: Gradient volatilization system: A three-stage volatilization system is constructed by 30-50% ethanol, 0.1-1% aminomethyl propanol, and 1-5% butanediol.

[0009] Among them, ethanol evaporates quickly (boiling point 78°C) to form the initial shaping network; aminomethyl propanol evaporates moderately (boiling point 165°C) to extend film formation time; and butanediol evaporates slowly (boiling point 190.3°C) to maintain film flexibility. By rationally combining these three alcohols with different boiling points, a gradient evaporation system is formed, achieving quick drying and long-lasting shaping.

[0010] Dual-Phase Film-Forming System: A dual-phase film-forming system is constructed using 5-15% octylacrylamide / acrylates / butylaminoethyl methacrylate copolymer and 0.5-2% PEG-12 polydimethylsiloxane. The octylacrylamide / acrylates copolymer (5-10wt%) is a hard phase, providing structural support, while the PEG-12 polydimethylsiloxane (1-3wt%) is a soft phase, filling the network pores. The crosslinking between the copolymer molecules enhances the film's toughness and adhesion, resisting the effects of external forces and humidity, and maintaining stable hair styles.

[0011] Bionic Repair System: Keratin 0.1-2%, Hydrolyzed Keratin 0.1-2%, Oxidized Keratin 0.1-2%, Polygonum Multiflorum Root Extract 0.5-3%, Aloe Barbadensis Extract 0.5-3%, Salvia Miltiorrhiza Root Extract 0.5-3%, Selaginella Vulgaris Extract 0.5-3%. Hydrolyzed keratin, with a molecular weight of 800-1200 Da, penetrates the hair cortex to repair disulfide bonds; keratin fills damaged cuticles and improves hair smoothness; Aloe Vera Extract, containing polysaccharides and amino acids, moisturizes and nourishes; Salvia Miltiorrhiza and Polygonum Multiflorum Extracts provide antioxidant properties, reducing UV damage to the hair.

[0012] Quick-drying film formation is achieved through the compounding of film-forming polymers and compounding volatile systems, combined with keratin ingredients (keratin, hydrolyzed keratin, oxidized keratin) to repair hair structure, and plant extracts (aloe vera, Selaginella, Polygonum multiflorum, Salvia miltiorrhiza) are used to provide moisturizing and antioxidant effects. At the same time, the aerosol process is optimized to ensure that the spray is fine and uniform, thereby improving styling efficiency and durability.

[0013] To achieve the above technical objectives, the present application provides a quick-drying styling spray, which comprises the following components by weight percentage: 30-50% ethanol, 0.1-1% aminomethyl propanol, 1-5% butylene glycol, 5-15% octylacrylamide / acrylates / butylaminoethyl methacrylate copolymer, 0.5-2% PEG-12 polydimethylsiloxane, 0.1-2% keratin, 0.1-2% hydrolyzed keratin, 0.1-2% oxidized keratin, 0.5-3% aloe vera extract, 0.5-3% selaginella extract, 0.5-3% polygonum multiflorum root extract, 0.5-3% salvia miltiorrhiza root extract, 20-40% water, 0.1-2% fragrance, 0.1-1% cetrimonium chloride, 0.5-1.5% phenoxyethanol, 1-5% propylene glycol, 0.5-1.5% parahydroxyacetophenone, 0.1- 0.5%, ethylhexylglycerin 0.5 - 1.5%.

[0014] Furthermore, the mass ratio of the octylacrylamide / acrylic acid (esters) / butylaminoethyl methacrylate copolymer to PEG-12 polydimethylsiloxane is 10:1.

[0015] Furthermore, the mass ratio of ethanol:aminomethyl propanol:butanediol is 40:0.5:3.

[0016] Furthermore, the weight ratio of keratin: hydrolyzed keratin: oxidized keratin is 1:1:1.

[0017] Furthermore, the total content of the aloe vera extract, the Selaginella extract, the Polygonum multiflorum root extract and the Salvia miltiorrhiza root extract is 2-10%.

[0018] Furthermore, the essence is sandalwood essence, and the content is 0.5-1.5%.

[0019] Furthermore, the spray dosage form is an aerosol, and the pressure packaging contains a flammable propellant.

[0020] The present invention also provides a method for preparing the quick-drying styling spray, comprising the following steps: uniformly mixing water, aminomethyl propanol, butylene glycol, and propylene glycol, adding PEG-12 polydimethylsiloxane and cetrimonium chloride and stirring until dissolved, sequentially adding aloe vera extract, Selaginella extract, Polygonum multiflorum root extract, and Salvia miltiorrhiza root extract, and mixing evenly, and then adding ethanol, octylacrylamide / acrylates / butylaminoethyl methacrylate copolymer, keratin, oxidized keratin, hydrolyzed keratin, phenoxyethanol, p-hydroxyacetophenone, chlorphenesin, and ethylhexylglycerin, and finally adding essence, homogenizing and filtering, and then filling into an aerosol can, filling with propellant, and sealing.

[0021] Furthermore, the propellant is propane, butane or dimethyl ether, and the amount of the propellant is 10-20% of the spray weight.

[0022] The present invention also provides a use of the quick-drying hair styling spray, which is used for hair styling and has a lasting styling effect of 6 to 24 hours.

[0023] Beneficial effects (1) Fast drying and long-lasting setting. Through the gradient volatilization system (ethanol, aminomethyl propanol, and butanediol), the spray can be dried quickly within 1-2 minutes, which is significantly better than the 5-10 minute drying time of traditional products. The three-stage volatilization system works synergistically to ensure uniform and long-lasting film formation, with a 24-hour setting retention rate of ≥95%, far exceeding the 2-4 hour durability of commercial products. Aminomethyl propanol is used as a volatility regulator. The hydroxyl groups in its molecules form a hydrogen bond network with ethanol, allowing the ethanol molecules to be released in an orderly manner, and the volatilization rate is increased by 40% (measured 0.6±0.1 minutes).

[0024] (2) Flexible and natural styling effect. The two-phase film-forming system (octylacrylamide / acrylates / butylaminoethyl methacrylate copolymer and PEG-12 polydimethylsiloxane) is compounded in a ratio of 10:1 to form a polymer film with a moderate elastic modulus (8.5×10 5 Pa), leaving hair feeling naturally flexible and supple, avoiding the stiffness or brittleness of traditional formulas. Its deformation rate over time is less than 3%, maintaining stable hairstyles even in an environment with 80% humidity, and exhibiting excellent moisture resistance. Furthermore, the butylaminoethyl ester groups in the copolymer undergo ion-dipole interactions with cetrimonium chloride, maintaining a polymer film elastic modulus of 105-106 Pa and a deformation rate of less than 3% over time (24-hour test).

[0025] (3) Highly effective repair and hair care. The bionic repair system (keratin, hydrolyzed keratin, oxidized keratin) works in synergy with plant extracts (aloe vera, Polygonum multiflorum, etc.) to repair the integrity of the hair scales by 90%, increase the breaking strength to 58cN, and significantly improve hair quality problems caused by chemical damage. The cysteine ​​residues (-SH) of hydrolyzed keratin exchange with the disulfide bonds (-SS-) of hair keratin, with a repair rate of 45-48% (SEM observation). Combined with antioxidant ingredients to reduce UV damage, long-term use can enhance hair luster and toughness.

[0026] (4) Safe and mild ingredients. Abandoning a high-concentration single ethanol system reduces damage to the hair cuticle, and adding moisturizing ingredients such as propylene glycol and aloe vera reduces the risk of hair drying. Plant extracts (such as Salvia miltiorrhiza and Selaginella) are naturally mild, reducing the risk of allergies and are suitable for people with sensitive scalps.

[0027] (5) Process optimization and user experience. The aerosol process ensures a fine and uniform spray with wide coverage, avoiding localized clumping or stickiness. Sandalwood fragrance (0.5-1.5%) provides a fresh aroma and enhances the user experience.

[0028] (6) Multifunctional integrated design. One product can simultaneously achieve the triple effects of quick drying, long-lasting styling, and hair repair and care, simplifying the user's care steps and meeting the needs of modern consumers for efficiency and convenience.

[0029] (7) Environmental protection and economy. The use of biodegradable propellants (propane / butane) reduces environmental pollution. The scientific proportion of the formula components avoids excessive addition of ineffective ingredients and reduces production costs. DETAILED DESCRIPTION

[0046] Experimental testing Experiment 1: Effect of gradient evaporation system on quick-drying and setting durability Test indicators: ① Dry Time: The time from spraying to the hair becoming completely tack-free (standard: ≤2 minutes is optimal). ② 24-Hour Style Retention: Using the hair strand drop method, measure the height change at the end of the hair strand (referring to the laboratory's internal standard: Retention = (H24 / H0) × 100%).

[0047] Test method: a. Take 10 standard hair bundles (20 cm, 0.5 g / bundle), treat 5 bundles in each sample group, and keep 5 bundles in the control group (no treatment).

[0048] b. After shaking the spray evenly, spray it at a distance of 15 cm from the hair for 20 seconds. Measure the initial height (H0) at room temperature (25°C, humidity 60%) and after drying. Measure the height (H24) after hanging for 24 hours.

[0049] Experiment 2: Effect of dual-phase film-forming system on film flexibility Test indicators: Membrane elastic modulus: Dynamic mechanical analysis (DMA) was used to measure the elastic modulus of polymer membranes at room temperature (standard: 10 5 -10 6 Pa is moderately flexible).

[0050] Deformation rate over time: After the hair bundle is shaped, it is placed in an environment with 80% humidity for 24 hours and the change in the bending angle of the hair bundle is measured (standard: deformation rate <5% is excellent moisture resistance).

[0051] Experiment 3: Repair effect of bionic repair system on hair damage Test indicators: Cuticle integrity: Observe the hair surface using a scanning electron microscope (SEM) and calculate the percentage of intact cuticle area (standard: ≥85% indicates significant repair).

[0052] Breaking strength: The maximum load that a single hair strand can withstand when stretched to break (standard: ≥50cN for improved strength). Test results and analysis Table 1: Performance comparison of gradient volatilization systems

[0053] in conclusion: The quick-drying time of the gradient volatilization system of the present invention (Examples 1-3) is ≤ 2 minutes, which is significantly better than the traditional monoethanol system (Comparative Examples 1-2), and the 24-hour retention rate is ≥ 95%, proving that the combination of alcohols with different boiling points can synergistically improve volatilization efficiency and film-forming stability.

[0054] Although high ethanol content (Comparative Example 2) shortens the quick-drying time, the rapid volatilization of the low-boiling point solvent leads to uneven film formation, and the setting retention rate decreases significantly in a humid environment.

[0055] Table 2: Performance comparison of dual-phase film-forming systems

[0056] in conclusion: When the ratio of the hard phase (copolymer) to the soft phase (siloxane) in the two-phase film-forming system is 10:1 (Example 1), the elastic modulus is optimal, and the film layer is flexible and has strong deformation resistance.

[0057] The lack of a soft phase (Comparative Example 3) results in a hard and brittle film layer, with a deformation rate exceeding 5% over time, verifying the key role of the soft phase in filling pores and enhancing toughness.

[0058] Table 3: Comparison of repair effects of bionic repair systems

[0059] *The control group consisted of untreated hair.

[0060] in conclusion: The combination of keratin ingredients and four plant extracts (Example 1) has the best repair effect, with the integrity of hair scales increased by 38% and the breaking strength increased by 53%, which is significantly better than the formula of a single ingredient (Comparative Example 5) or the formula without Polygonum multiflorum (Comparative Example 4).

[0061] Hydrolyzed keratin (800-1200Da) penetrates into the hair cortex to repair disulfide bonds, combined with plant extracts for antioxidant effects, synergistically improving hair structure.

[0062] Conclusion The gradient volatile system achieves a balance between quick drying and long-lasting setting by compounding alcohols with different boiling points. The optimal ratio is 40% ethanol + 0.5% aminomethyl propanol + 3% butylene glycol.

[0063] When the ratio of hard phase to soft phase in the two-phase film-forming system is 10:1, the film has the best flexibility and moisture resistance, avoiding the defects of traditional formulas that are rigid and easy to break.

[0064] The bionic repair system relies on the synergy of keratin-like ingredients (1:1:1 compound) and four plant extracts to significantly improve hair repair efficiency, verifying the necessity of multi-component compounding.

[0065] The present invention solves the technical problem of traditional styling sprays that it is difficult to achieve both quick drying and nourishing through the coordinated design of three major systems, and has significant innovation and practical value.

[0066] It should be understood by those skilled in the art that the above embodiments are merely exemplary embodiments and that various changes, substitutions, and alterations may be made without departing from the spirit and scope of the present application.
