TECHNICAL FIELD
[0001] The present application belongs to the technical field of daily chemical products, and particularly relates to a biological enzyme wig care solution and a preparation method and application thereof. BACKGROUND
[0002] In recent years, with the diversification of aesthetics and consumption upgrading, the global wig market has shown explosive growth. High-frequency use scenarios have given rise to a strong dependence on wig care products. At the same time, consumers' concerns about the safety of care solutions have increased dramatically. Hair care product complaints are mainly focused on the irritating ingredients of traditional care solutions, such as silicone residue causing scalp allergies, and excessive formaldehyde release. Consumers have explicitly requested products with "non-toxic, biodegradable" certification.
[0003] However, current commercially available products and traditional technologies still have significant defects. Traditional wig care solutions mainly rely on silicone oil, cationic surfactants, or single biological enzyme preparations. Silicone oil products (such as polydimethylsiloxane) can temporarily improve smoothness, but have poor wash resistance, low air permeability, and can cause environmental problems; traditional cationic surfactants, such as cetyltrimethylammonium chloride, have short-term anti-static effects, and high concentrations can easily cause fiber charge aggregation, exacerbate frizz rebound, and commercially available wig care solutions also cannot effectively improve the dry and frizzy problems of wigs caused by long-term wear; the single enzyme treatment technology that has emerged in recent years can partially repair the cuticle, but over-enzymatic degradation can lead to a decrease in fiber strength and incomplete repair, making it difficult to balance long-term anti-frizz and wig fiber protection needs. If users want to restore the smooth state of wigs, they may need to send the products back to the factory for repair repeatedly, which undoubtedly increases the time and economic costs of users and reduces user experience. The above problems seriously restrict the user experience and sustainable development of wig products, and therefore, developing a long-term anti-frizz, low-damage, green, healthy, and convenient-to-use wig care solution is an urgent problem in the industry.

[0115] (2) Weigh 20.0 g of cationic guar gum. Preheat the citric acid-sodium citrate buffer solution to 40°C in a 50°C water bath. Slowly add the guar gum to the surface of the citric acid-sodium citrate buffer solution (avoid clumping), and emulsify and disperse at 2000 rpm for 15 minutes to form a transparent colloid.
[0116] (3) Add 40.0 g of lauroyl hydrolyzed wheat protein to the transparent colloid, stir in a constant temperature water bath at 45°C for 20 minutes until completely dissolved; after cooling to 30°C, add 12.0 g of keratinase and 12.0 g of lipase, stir at low speed until the enzymes are completely dissolved to avoid loss of enzyme activity, then add deionized water to a total mass of 1000 g, mix well and then pass through a 200 mesh screen to remove undispersed particles. The resulting solution is the bioenzyme wig care solution.
[0117] The above wig care solution was used to test damaged wigs (hair damage procedure according to Appendix A of T / GDCA017-2023), with the following steps:
[0118] (1) Dilute the bioenzyme wig care solution with water, adding 30 mL of bioenzyme wig care solution per 1000 mL of water.
[0119] (2) Wash the wig with shampoo.
[0120] (3) Soak the washed wig in the diluted bioenzyme wig care solution at 38 ± 2°C for 30 minutes to repair the wig.
[0121] (4) Dry the wig with a cold air setting on a blow dryer, then use an adjustable temperature straightening board set to 60°C to clamp the wig in sections. Slowly lower the clamp after closing it (each section stays for ≤5 seconds). After the wig is completely treated, use the blow dryer on cold air setting for 1 minute to lock the surface structure.
[0122] The electrostatic properties of the wig before and after care were measured according to GB / T 33730-2017 "Hair Products - Evaluation of Electrostatic Properties"; the combing properties of the wig before and after care were evaluated according to T / GDCA 017-2023 "Hair Care Product Hair Care Efficacy Evaluation Method"; the flexibility of the wig before and after care was evaluated according to GB / T 43004-2023 "Hair Products - Flexibility Test Method", and the results are shown in Table 1.
[0123] Table 1 Comparison of electrostatic properties, combing properties and flexibility of various wig care solutions
[0124]
[0125] The greater the flexibility coefficient and the smaller the hair combing force value in Table 1, the more flexible the wig; electrostatic half-life ≤3.0 s is A grade; electrostatic half-life ≤7.0 s is B grade; electrostatic half-life ≤15.0 s is C grade.
[0126] From Table 1, compared with Comparative Example 4 (no damaged wig care), Comparative Examples 1-3 can improve the wig roughness and increase the smoothness to some extent, but the improvement effect is poor; after the wigs in Example 1-3 are treated by the wig care liquid provided by the present application, the wig smoothness coefficient is significantly improved, the combing force is significantly reduced, the anti-static ability of the wig is also obviously improved, and the improvement effect is significantly better than that of Comparative Examples 1-3. Compared with Comparative Examples 5-6, when the cationic guar gum has a substitution degree of 0.12-0.25, the wig roughness can be significantly improved, and the wig smoothness can be obviously improved.
[0127] The above results show that the present application can greatly improve the wig roughness after use, improve the wig smoothness and anti-static performance, and is significantly better than the traditional care liquid treatment method and the commercially available care liquid. The present application is green and healthy, easy to operate at home, and the use method is simple, which can effectively solve the time and economic cost problems caused by the need to return the wig to the factory for repair after the wig becomes rough, and greatly improve the user experience.
[0128] The above examples are only illustrative of the present application, and do not constitute a limitation on the protection scope of the present application, and any design identical or similar to the present application belongs to the protection scope of the present application.
