Description

Technical Field

[0001] This invention relates to the field of daily cosmetics, and in particular to a shampoo for oil control, volumizing, and deep nourishment, and its preparation method. Background Technology

[0002] With the fast pace of life, environmental pressures (such as air pollution and UV radiation), and poor hair care habits (such as over-cleaning and frequent perming and dyeing), scalp microecological imbalance and hair damage are becoming increasingly common. Consumers' demands for shampoo have evolved from "basic cleaning" to a multi-functional approach that combines "oil control, volumizing, and deep nourishment." However, existing technologies still have significant limitations and struggle to meet market demands. For example, current oil-control shampoos often rely on "strong cleansing surfactants" (such as sodium lauryl sulfate and ammonium lauryl ether sulfate) to achieve their oil-removing effect. While these surfactants can remove excess scalp oil in the short term, they also strip away the scalp's natural sebum film, damaging the scalp barrier and causing dryness, sensitivity, and redness. This can even stimulate the sebaceous glands to compensate by secreting more oil, creating a vicious cycle of "the more you wash, the oilier it gets." Furthermore, oil-control formulas often focus on "oil removal" while neglecting "repair." Long-term use can lead to hair cuticles opening due to lack of oil nourishment, resulting in dry, frizzy, and split ends. Existing nourishing shampoos contain large molecular structures (such as vitamin E and plant oils) that, without optimization through nanotechnology and emulsification, struggle to penetrate the hair cuticle and reach the hair core. They remain only on the surface, failing to achieve "deep nourishment" and thus offering limited repair effects. This indicates a common technical challenge in the current shampoo market: a conflict between oil control and nourishment. Consumers urgently need a shampoo that can simultaneously address both needs. Summary of the Invention

[0085] Experiment Example 1: Product Safety Experiment 1.1 Experimental Methods The study participants were 30 women aged 20-40 years old. The participants had healthy skin, no history of skin diseases, allergies, eczema / dermatitis, and had not recently used hormone drugs or immunosuppressants. In addition, the participants had to avoid using other skin care products, sun exposure, or friction on the test site (mostly the back) for 48 hours before the experiment. The participants met the voluntary inclusion criteria.

[0086] The test products were the shampoos prepared in Examples 1-3 and Comparative Examples 1-8, and the blank control group was physiological saline. A patch tester was used, employing a closed-loop human skin patch test method. 50 μL each of the shampoos prepared in Examples 1-3 and Comparative Examples 1-8 and physiological saline were applied to a sterile patch test chamber (approximately 8-12 mm in diameter). The test skin was divided into 12 areas. The patch test chambers were then applied to healthy skin on both sides of the spine on the back and secured with medical tape. After 48 hours, the test products were removed. Skin reactions were observed at 30 min, 12 h, 24 h, and 48 h after removal, and the results were recorded according to the ICDRG grading standard for skin reactions in the "Cosmetic Hygiene Standard" (Table 1).

[0087] Acceptance criteria: If all test subjects have a reaction of ≤1 and no reaction of 2 or above, the product is usually judged to have "no obvious irritation / sensitization to human skin"; if the proportion of people with a reaction of ≥2 exceeds the prescribed proportion (e.g., 5%), the product safety risk needs to be assessed, and the formula may need to be adjusted and the experiment repeated.

[0088]

[0089] 1.2 Experimental Results After closed-loop human skin patch testing, the skin reactions of subjects in each group were observed at 30 min, 12 h, 24 h, and 48 h after using the shampoos of Examples 1-3 and Comparative Examples 1-8. No adverse skin reactions were observed, indicating that the shampoos are safe to use and non-irritating.

[0090] Experiment Example 2 Stability Test 2.1 Experimental Methods The shampoos prepared in Examples 1-3 of this invention were placed in environments of -10℃ and 58℃ for 6 months, respectively, and the shampoos were observed to separate into layers and precipitate flocculent matter.

[0091] 2.2 Experimental Results As shown in Table 2, the shampoo prepared by this invention has strong stability.

[0092]

[0093] Oil control effect in Experiment Example 3 3.1 Experimental Methods 66 volunteers were recruited, including 33 males and 33 females, divided into 11 groups with 6 people in each group (3 males and 3 females). The average initial oil content of the scalp on the top of the head of the volunteers in each group was measured using the oil tester SM815, denoted as the initial oil content P0. Then, each group used the shampoos prepared in Examples 1 - 3 and Comparative Examples 1 - 8 to wash their hair for 2 months, washing their hair once every 2 days. The oil contents after using for 15 days, 1 month, and 2 months were measured, denoted as the oil contents P1, P2, and P3 after use. The reduction rate of oil in different time periods was calculated, and the oil reduction rate = 100%×(initial oil content - oil content after use) / initial oil content.

[0094] 3.2 Experimental results The results are shown in Table 3. After using the shampoos prepared in Examples 1 - 3 for 2 months, the oil reduction rate was between 61.7% and 63.1%. It can be seen that the formula used in the present invention can significantly reduce scalp oiliness. Comparing Example 3 with Comparative Examples 1, 3, and 7, it can be known that the complete group formulation greatly affects the oil control effect. Sapindus mukorossi Gaertn. fruit extract, Celastrus paniculatus Willd. seed extract, and Viola odorata L. oil are components carefully selected through multiple experiments to have the best effect; comparing Example 3 with Comparative Examples 2, 4, and 6, it can be known that the lack of a certain component will reduce the oil control effect; comparing Example 3 with Comparative Examples 5 and 8, it can be known that the addition form and the amounts of each component of the hesperidin laurate - rosmarinic acid composite nanoemulsion affect the oil secretion amount. If the preparation method and the addition amounts of each component are not strictly controlled, it will lead to poor oil control effect.

[0095]

[0096] Experimental Example 4 Determination of hair combability 4.1 Experimental method Wet combability test: The shampoos prepared in Example 3 and Comparative Examples 1 - 8 were diluted 10 times with water and measured after washing the hair bundles. The hair bundles (severely damaged hair bundles without hair care treatment) were clamped in the stainless - steel clips supporting the combing instrument, tightened with screws to fix them, and the hair bundles were slightly combed with a comb to make them not knotted. Then the hair bundles were hung on the rack of the combing instrument. To prevent the comb from separating from the hair during the combing process, a rubber band was used to fix the hair in the teeth of the comb. Press the "start" button, and the comb began to comb from the root to the tip of the hair. Record the friction force (g) when the comb reached 10 cm from the root. After each measurement, the hair bundle was re - wetted with warm water, and measured three times in parallel, taking the average value. Using distilled water to wash the hair was used as the blank control group.

[0097] Dry combability test: After the wet combability test, the hair strands were placed in an artificial climate chamber to dry (the temperature of the climate chamber was set to 25℃ and the relative humidity was set to 60%) to simulate the drying process of people's hair after washing in real life. After the hair strands were dry, the dry combability test was carried out. Press the "start" button and the comb started to comb from the hair root to the hair tip. Record the friction force (g) when the comb is 10cm from the hair root. Each sample was measured 3 times and the average value was taken.

[0098] 4.2 Test Results The test results are shown in Table 4:

[0099] As shown in Table 4, the shampoos prepared in Example 3 and Comparative Examples 1-8 all had a certain smoothing and nourishing effect on the hair compared with the blank control group, especially Example 3, which had the best effect.

[0100] Experiment Example 5: Antibacterial Experiment 5.1 Experimental Methods Referring to Appendix C4 "Test Method for Antibacterial Performance of Dissolving Antibacterial (Inhibitory) Products" of GB15979-2002 "Hygienic Standard for Disposable Sanitary Products", the antibacterial performance of Malassezia furfur prepared in Examples 1-3 and Comparative Examples 1-8 of this invention was tested. Referring to "7.5 Test Method for Antibacterial Effect of Daily Chemical Products (Inhibition Ring Method)" of "Evaluation Method for Antibacterial and Antimicrobial Effects of Daily Chemical Products" (QB / T 2738—2023), the diameter of the inhibition ring in Experimental Example 3 was tested.

[0101] 5.2 Experimental Results The diameter of the inhibition zone in Experiment 3 was 32.6 mm. The antibacterial effect is shown in Table 5. The shampoo prepared by this invention showed an inhibition rate of over 96% against Malassezia furfur, demonstrating a significant inhibitory effect. The shampoos prepared in Examples 1-3 all showed higher inhibition rates against Malassezia furfur than those prepared in Comparative Examples 1-8. Example 3 involved combining Sapindus trifoliata fruit extract, Ligusticum chuanxiong seed extract, hesperidin laurate-rosmarinic acid composite nanoemulsion, and violet oil. The interaction between these active ingredients inhibited the growth of Malassezia furfur. In particular, the addition of a composite nanoemulsion of hesperidin laurate and rosmarinic acid to the shampoo improved the solubility of the active ingredients, reduced precipitation and stratification, and formed an adsorption film on the hair surface through small-particle nanoemulsion, prolonging the residence time and allowing penetration into the superficial layer of the scalp stratum corneum or the hair cuticle, directly acting on the Malassezia furfur hidden therein.
