Description

Technical Field

[0001] This invention relates to skin care product technology, specifically to a Litsea cubeba hand cream composition, its preparation method, and its application. Background Technology

[0002] As a core product in daily personal care, hand cream's basic skincare functions such as moisturizing and soothing have become a basic requirement. However, consumers have raised higher demands for the product's fragrance experience, user experience, and the balance between efficacy and fragrance.

[0003] Chinese invention patent CN202410518979.5 discloses an antibacterial composition based on Litsea cubeba fruit oil and a surfactant, comprising: 0.01-5% by weight of Litsea cubeba fruit oil; 0.1-10% by weight of polyglycerol monolaurate; 0.1-10% by weight of glyceryl caprylate; and a carrier acceptable in the field of household cleaning products or personal care products. This invention also relates to the use of the composition based on Litsea cubeba fruit oil and a surfactant in the preparation of household cleaning products or personal care products with antibacterial properties.

[0004] However, this composition focuses on antibacterial function and has a relatively simple fragrance design. It does not combine the distinctive aromas of natural plant essential oils with niche fragrances, resulting in a thin fragrance layer and a poor experience. Summary of the Invention

[0005] The purpose of this invention is to provide a Litsea cubeba hand cream composition, its preparation method, and its application, in order to solve the problems of thin fragrance layers and poor user experience in the prior art.

[0010] The thickening phase component C: SEPIGEL 305 1.2-2.0%;

[0011] The functional phase component D further includes: bisabolol 0.1-0.2%, β-glucan-PF (Gioactive SPG-PF) 0.0005-0.0015%, phytosoothing agent (Comthing SGS) 0.08-0.12%, carnosine (β-alanyl-L-histidine) 0.008-0.012%, active collagen 0.0005-0.0015%, and 2-methyl-2,4-pentanediol 0.3-0.7%.

[0012] Further, the aqueous phase component A comprises 67.0260% water, 5.0% glycerol, 0.0010% sodium hyaluronate, 0.5% vitamin C ethyl ether, 0.0010% tremella polysaccharide (WSK), and 0.3% allantoin;

[0013] The oil phase component B consists of shea butter 5.0%, XIAMETER PMX-200 Silicone Fluid 350 cSt 2.0%, ROCKSUS BHT 0.05%, RFA C1618 2.0%, FEELZ GC 206 5.0%, 26# white oil 4.0%, SP BR1JS721 MBAL-PA-(SG) 1.0%, TEGO CARE 165 MB 2.0%, DL-alpha-Tocopheryl Acetate 0.5%, pharmaceutical grade petrolatum 2.5%, olive (OLEA EUROPAEA) fruit oil 0.5%, and sunflower seed oil 0.11%.

[0014] The thickening phase component C is SEPIGEL 305 1.6%;

[0015] The functional phase component D consists of 0.15% bisabolol, 0.0010% β-glucan-PF (Gioactive SPG-PF), 0.10% phytosoothing agent (Comthing SGS), 0.010% carnosine (β-alanyl-L-histidine), 0.0010% active collagen, 0.5% 2-methyl-2,4-pentanediol, 0.10% litsea fruit oil, and 0.05% smoked leather fragrance.

[0016] A method for preparing the Litsea cubeba hand cream composition as described above includes the following steps:

[0017] S1. After cleaning and disinfecting the production equipment, weigh each raw material of aqueous phase component A, oil phase component B, thickening phase component C and functional phase component D according to their weight percentage.

[0018] S2. Add aqueous phase component A to the water pot, heat to 80-85℃ to dissolve and keep warm for 30 minutes. Add oil phase component B to the main pot, heat to 80-85℃ to dissolve and keep warm for 30 minutes.

[0019] S3. Pump the aqueous phase component A into the main pot and mix it with the oil phase component B. Stir and homogenize at 80-85℃ for 10-15 minutes.

[0020] S4. Cool down to 60-65℃, add thickening phase component C, stir and homogenize for 5-10 minutes, then keep warm for 20 minutes.

[0021] S5. Continue cooling to 38-45℃, add functional phase component D sequentially and stir until evenly mixed;

[0022] S6. Cool to 35-38℃, filter through a 300-mesh filter cloth, let stand, take samples for testing, and after passing the test, fill, code, seal and store in the warehouse.

[0023] Furthermore, in step S5, when the material is cooled to 42°C, functional phase component D is added, and a low-speed stirring method of 200 r / min is used during the addition.

[0024] An application of the Litsea cubeba hand cream composition as described above, wherein the composition is used to prepare a fragrant hand cream product with moisturizing and soothing skin care effects.

[0025] Furthermore, the fragrance hand cream is suitable for all skin types, especially for the daily care of dry and sensitive hands.

[0026] Compared with the prior art, the litsea cubeba hand cream composition, its preparation method, and its application provided by the present invention have the following beneficial effects:

[0027] 1. The spicy and natural plant aroma of Litsea cubeba fruit oil is blended with the mellow and rich fragrance of smoky leather essence to create a fragrance that is different from traditional floral and fruity scents, thus overcoming the limitation of the single fragrance type in existing hand creams.

[0028] 2. This invention avoids the complex techniques of nano-encapsulation and microcapsule encapsulation in existing technologies. By adding functional phase component D containing Litsea cubeba fruit oil and smoked leather fragrance at a low temperature of 38-45℃, it solves the stability problems of easy volatility and oxidation of plant essential oils. Moreover, this invention adopts a conventional emulsification process, which does not require complex special production equipment. The process is simple and easy to operate, making it suitable for large-scale industrial production and significantly reducing production and R&D costs.

[0029] 3. By adding raw materials in stages and at controlled temperatures, the damage of high temperatures to fragrance raw materials and plant essential oils is effectively avoided. This not only protects the bioactivity of the Litsea cubeba fruit oil and ensures its skincare efficacy, but also reduces the volatilization of fragrance raw materials.

[0030] 4. The formula constructs a simple and efficient skin care system with sodium hyaluronate, UKfinecare series, shea butter, and olive fruit oil as the core, with multiple moisturizing and soothing ingredients working synergistically; the addition of bisabolol and plant soothing agents further enhances the product's soothing effect;

[0031] 5. Through fragrance blending and process optimization, a high-quality fragrance experience has been effectively integrated, solving the problem of "heavy fragrance and light efficacy" or "heavy efficacy and light fragrance" in existing fragrance hand creams, and improving the overall use value of the product.
