Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to a leave-on scalp care hair wax composition and its preparation method. Background Technology

[0002] As an important component of human skin, the health of the scalp directly affects hair follicle vitality and hair quality. Scalp care not only includes basic cleansing and moisturizing, but also involves multiple dimensions such as sebum secretion regulation, maintenance of microenvironment balance, and improvement of visual appearance. In practical applications, there are challenges in developing products that combine styling functions with care effects: traditional hair waxes often use high amounts of film-forming polymers and waxes to achieve a styling effect, resulting in a thick texture that can easily clog pores and cause sebum secretion imbalance with long-term use; at the same time, product residue on the hair can easily combine with shed keratinocytes to produce visible flakes that are difficult to remove completely with regular washing.

[0003] To address the aforementioned issues, this invention constructs a lipid-phase base comprising a specific ratio of synthetic and plant waxes, combined with a film-forming polymer composite system exhibiting different glass transition temperatures. This allows the product to significantly improve rinsing convenience while maintaining moderate styling power. By selecting powder materials with varying surface modifications, a matte finish is provided while effectively reducing the visual appearance of dandruff. Furthermore, the introduction of a herbal complex containing standardized active ingredients and a controlled-release fragrance module provides continuous scalp care and enhances the user experience. This design ultimately achieves a scalp care hair wax that strikes a good balance between styling performance, care functions, and user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a scalp care hair wax composition and its preparation method, thus solving the technical problems mentioned in the background section.

[0019] In this embodiment, the mass ratio of the VP / VA copolymer to the acrylate polymer is (2-3):1.

[0020] This embodiment is further configured to include the following steps: (a) heating and melting the wax / lipid phase component at 75°C to 85°C to obtain a uniform oil phase; (b) dissolving the aqueous phase component in water at 70°C to 80°C to obtain a uniform aqueous phase; (c) adding the oil phase to the aqueous phase under stirring, performing high-shear emulsification, and then stirring at medium speed to cool down; (d) adding the film-forming system when the temperature drops to 55°C to 65°C and stirring evenly; (e) adding the tactile powder when the temperature drops to 45°C to 50°C and dispersing evenly; (f) adding the herbal effective component compound and flavor control module when the temperature drops below 40°C and stirring evenly; (g) adjusting the pH value of the composition to 5.0-5.8, degassing, and then filling.

[0022] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0023] Example: The leave-on scalp care hair wax of the present invention is achieved through the following process: First, an oil phase is prepared by placing 8.0g of microcrystalline wax, 3.0g of hydrogenated castor oil, and 3.0g of cetyl alcohol in a jacketed heating pot, heating to 80±2℃ and maintaining low-speed stirring until the system forms a uniform molten state. Simultaneously, an aqueous phase is prepared by adding a measured amount of purified water to another mixing pot, heating to 75±2℃, and then sequentially adding 1.0g of Ceteareth-20, 0.8g of glyceryl stearate, 1.0g of propylene glycol, 0.8g of butylene glycol, and 0.05g of EDTA-2Na, stirring at 200rpm using a propeller stirrer until completely dissolved.

[0024] Transfer the preheated aqueous phase (to 75°C) into the homogenizing emulsifying tank, maintaining the temperature at 75±2°C. Turn on the homogenizer and adjust the speed to 3000 rpm. Under these conditions, slowly draw the oil phase (maintained at 80°C) into the emulsifying tank via vacuum suction. Once all the oil phase has been drawn in, increase the homogenizer speed to 5000 rpm and continue emulsifying for 2 minutes until the system appears uniformly milky white. After completion, switch to slow-speed scraping and stirring, turn on the jacketed cooling water, and control the temperature reduction at a rate of 1.5-2°C per minute.

[0025] When the material temperature drops to 60±2℃, slowly add 3.5g of VP / VA copolymer emulsion and 1.5g of acrylate copolymer emulsion through the side feed port, and maintain slow stirring for 15 minutes to ensure the film-forming system is fully dispersed. When the temperature drops to 50±2℃, add the homogeneous slurry prepared in advance by using a three-roll mill with 0.75g of oleophilic silica, 0.75g of hydrophilic silica, and 0.8g of nylonyl-12 and 5g of deionized water to the system, and continue stirring for 20 minutes to ensure complete dispersion of the powder.

[0026] When the temperature drops to 38±2℃, add the following ingredients in sequence: 3.0g of herbal compound containing 0.1g of osthol, 0.15g of glycyrrhizic acid monoammonium salt and 0.3g of total flavonoids from Smilax glabra; 0.25g of polyquaternium-67; 0.2g of zinc pyrrolidone carboxylate; 0.5g of nicotinamide; 0.1g of caffeine; 0.03g of menthol; 0.15g of zinc ricinoleate; 0.15g of β-cyclodextrin; and 0.08g of woody fragrance. Adjust the stirring speed to 40-50 rpm and continue mixing for 30 minutes to ensure uniform distribution of the heat-sensitive components.

[0027] Finally, the pH of the system was adjusted to 5.3±0.1 with a 10% citric acid aqueous solution. The mixture was then transferred to a vacuum degassing tank and degassed for 15 minutes at -0.08 MPa. The degassing was then pumped to a filling machine and quantitatively filled into aluminum packaging with a polypropylene liner. The black metal cap was then tightened to complete the packaging. The resulting product, as tested, is a uniform matte paste that exhibits good spreadability when applied between fingers without stringing. It forms a natural matte finish on hair. Laboratory tests show that it has reliable setting properties and is easy to clean.
