Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and in particular to a mild, tear-free bathing composition and its application in the preparation of baby bathing products. Background Technology

[0002] With consumers' increasing awareness of health and safety, especially their growing concern for the safety and gentleness of baby care products, the market demand for "tear-free formula" and "naturally gentle" bath and body products continues to grow. Infants' skin barrier function is not yet fully developed, they secrete less sebum, and their skin is more delicate and sensitive, easily irritated by external chemicals, leading to dryness and other problems. Therefore, developing a bath and body product that ensures effective cleaning while also being gentle, moisturizing, and soothing has become an important research direction for baby care products.

[0003] Currently available baby bath products may over-cleanse the skin's surface oils with prolonged or frequent use, damaging the skin barrier and leading to dryness and tightness. Furthermore, they are relatively irritating, easily causing significant stinging when accidentally in contact with the eyes. It is difficult to achieve an ideal balance between thorough cleansing, gentle tear-free application, and moisturizing and soothing effects. Modern baby bath products not only require "cleanliness without irritation" but also increasingly emphasize enhancing the skin's moisture retention capacity and alleviating potential discomfort caused by external environmental factors. Plant extracts, due to their natural origin and diverse bioactivities, have become preferred functional additives. However, how to select effective plant combinations, maximize the retention of their active ingredients through specific extraction processes, and ensure their compatibility with surfactant systems and the stability and safety of the final formula for daily baby care is a pressing issue that the market needs to address.

[0042] Test Case - Moisturizing Test Objective and Principle: Moisture in the stratum corneum plays a crucial role in maintaining skin health, preventing aging, and providing hydration. Dry skin is caused by insufficient moisture in the stratum corneum, and water often binds to the stratum corneum as bound water. An ideal moisturizing product should have the ability to retain moisture; that is, the smaller the change in moisture content, the stronger the moisturizing ability. This test method continuously monitors the change in moisture weight of the treated test samples, plotting a moisturizing rate-time curve. The moisturizing ability of the test samples is observed based on the trend of the moisturizing rate curve, thereby evaluating the moisturizing efficacy of the test samples on the skin.

[0043] Method relevance: This method is an in vitro method, and the trend of the in vivo method is somewhat correlated with the results of the in vitro method. Through experimental design, the test sample is compared with the test results of a positive control sample with moisturizing ability. If the moisturizing rate curve of the test sample is higher than (better than) the moisturizing rate curve of the positive control, then the test sample can be considered to have a certain moisturizing ability.

[0044] Methods: First, the samples were prepared into 10% (w / w) homogeneous solutions. After being drawn up, the solutions were slowly added dropwise to pre-weighed glass weighing bottles. 1 g of each solution was accurately weighed. Glycerin was used as a positive control. The weighing bottles were placed open in a constant temperature and humidity chamber at 25±1℃ and RH 32±2%. The change in water weight was monitored at 1.5 h and 3 h, and the data were recorded to calculate the moisture retention rate.

[0045] Moisture retention rate % = (Weight of sample moisture at a certain moment / Initial weight of sample moisture) × 100% The results are shown in Table 1.

[0046] Table 1

[0047] As can be seen from Table 1, the shampoos prepared in Application Examples 1-7 of the present invention have a better moisturizing rate than the positive control, and have a good moisturizing effect.

[0048] Test Case - Soothing Purpose and Principle of the Test: Hyaluronic acid is widely present in the skin and other tissues, and is closely related to skin hydration, elasticity maintenance, and barrier function regulation. High molecular weight hyaluronic acid can suppress inflammatory responses by inhibiting the release of inflammatory factors and reducing inflammatory cell infiltration, thereby alleviating discomfort symptoms caused by skin inflammation. Hyaluronidase is an important participant in type I hypersensitivity reactions and is strongly correlated with the inflammation and allergic process. High molecular weight hyaluronic acid is hydrolyzed under the catalysis of hyaluronidase, resulting in a decrease in its content and the production of degradation products such as glucuronic acid and N-acetylglucosamine. By measuring the content of the characteristic product N-acetylglucosamine in the reaction system, the hydrolytic activity of hyaluronidase is indirectly reflected, and the inhibition rate of hyaluronidase by the tested sample group can be calculated.

[0049] Method Relevance: This method is an in vitro method and is applicable to cosmetics claiming soothing effects. The trends of in vivo methods are somewhat correlated with those of in vitro methods. Through experimental design, the inhibition rate of the test sample on hyaluronidase is determined by measuring the N-acetylglucosamine content in the reaction system. If the inhibition rate of the test sample is better than (higher than) that of the blank control group and the statistical difference P value is <0.05, then the test sample can be considered to have a certain soothing effect.

[0050] The hyaluronidase inhibition rate before and after the addition of the test substance was calculated, and the statistical difference was P < 0.05.

[0051] Experimental procedure: 1. Prepare reagents: Acetate buffer: Take 4.8 mL of solution A (11.55 mL of 0.2 mol / L acetic acid dissolved in 1000 mL of distilled water) and 45.2 mL of solution B (16.4 g of 0.2 mol / L sodium acetate dissolved in 1000 mL of distilled water), mix and bring the volume to 100 mL to prepare an acetate buffer solution with pH=5.6; Hyaluronidase: concentration 500 U / mL, using acetate buffer as solvent; Sodium hyaluronate: 0.5 mg / mL, using acetate buffer as solvent; Sodium carbonate solution 1 mol / L: Accurately weigh 5.3 g of anhydrous sodium carbonate, dissolve it in distilled water, and bring the volume to 50 mL; Acetylacetone solution: Dissolve 3.5 mL of acetylacetone in 50 mL of 1.0 mol / L sodium carbonate solution and mix well; P-DAB colorimetric reagent: 0.8g of p-dimethylaminobenzaldehyde is dissolved in 15mL of concentrated hydrochloric acid and 15mL of anhydrous ethanol and mixed evenly; 2.5 mol / L CaCl2 solution: Weigh 27.745 g of calcium chloride and dissolve it in 100 mL of pure water; 5 mol / L NaOH solution: Weigh 20.0 g of sodium hydroxide and dissolve it in 100 mL of pure water; Test solution: Weigh 1.000g of sample, dissolve in 10mL of pure water / 10mL of ethanol, centrifuge by sonication and collect the supernatant for later use.

[0052] 2. Process:

[0053] Hyaluronidase inhibition rate = [(B 对照 -B 0对照空白 ) - (A 样品 -A 样品空白 )] / (B 对照 -B 0对照空白 )×100%.

[0054] Where A is the absorbance value of the sample solution, A0 is the absorbance value of the blank sample solution, B is the absorbance value of the control solution, and B0 is the absorbance value of the blank control solution.

[0055] The results are shown in Table 2.

[0056] Table 2

[0057] As can be seen from Table 2, the hyaluronidase inhibition rate of the shampoo prepared by application examples 1-7 of the present invention is better than that of the control, and the statistical difference P value is <0.05, indicating that the difference is significant and has a good soothing effect.

[0058] Test case - mild and non-irritating The shampoos prepared in Examples 1-7 were tested for their mild and non-irritating efficacy. The mild and non-irritating efficacy of the samples was verified using a blank control, according to TMPCIA006-2021 "Determination of Mild Irritation in Cosmetics - Zebrafish Embryo Method". Wild-type AB zebrafish were used in this test. The main test reagent was sodium dodecyl sulfate (SDS).

[0059] Experimental methods: Grouping and Control: Product Dosage Grouping: 0.00781% of the shampoos prepared in Examples 1-7. Control Information: ① Blank Control Group: Standard dilution water; ② Positive Control Group: 0.95 mg / mL SDS solution.

[0060] Main operating steps: 24 hpf (24 hours post-fertilization) wild-type AB zebrafish embryos with normal development were randomly selected and placed in 24-well cell culture plates, 10 embryos / well. A blank control group, a positive control group, and a test sample group were set up. Each group was treated with 1.0 mL of standard dilution water for 2 min. After counting the stress response frequency of the zebrafish embryos, 1.0 mL of the corresponding sample solution was added for 2 min (1.0 mL of standard dilution water was added to the blank control group, 1.0 mL of 0.95 mg / mL SDS solution was added to the positive control group, and 1.0 mL of the test sample solution was added to the test sample group). The stress response frequency of the zebrafish embryos was counted. Each experiment was repeated twice.

[0061] Judgment criteria:

[0062] The effects of the shampoos prepared in Examples 1-7 on the frequency of stress response in zebrafish embryos are shown in Table 3.

[0063] Table 3

[0064] It can be seen that after treating zebrafish embryos with standard dilution water for 2 minutes, the stress response frequency was 0.86±0.01 times / second, a decrease of 0.02 times / second compared to before sample addition (0.88±0.01 times / second). p>0.05), indicating that the standard dilution water had no significant effect on the stress response frequency of zebrafish embryos (not significant). After treating zebrafish embryos with 0.95 mg / mL SDS solution for 2 min, the stress response frequency was 2.23 ± 0.11 times / second, an increase of 1.38 times / second compared to before the addition (0.85 ± 0.08 times / second). p <0.01), indicating that 0.95 mg / mL SDS solution has a strong stimulating effect on zebrafish embryos (very significant). Under the same conditions, after treating zebrafish embryos with 0.00781% of the shampoo from Examples 1-7 for 2 min, the frequency of stress response did not increase significantly compared with before the addition of the sample. p >0.05), indicating that the shampoo used in Examples 1-7 did not significantly change the frequency of stress response in zebrafish embryos (not significant), and has a mild and non-irritating effect.
