Description

Technical Field

[0001] This invention relates to a transparent, moisturizing, multi-foaming bath oil. Background Technology

[0002] With social progress and economic development, people's living standards are constantly improving. Nowadays, in addition to facial skincare, people are paying more attention to the care and maintenance of their entire body's skin, making bath products one of the main products for this purpose. However, 99% of commercially available bath products are traditional shower gels. Their advantages are easy lathering and rich foam; their disadvantages include a slippery feeling after washing, difficulty in rinsing, dryness and sensitivity after washing, and a lack of effective moisturizing. Therefore, in recent years, bath oil products with good moisturizing properties have gained widespread attention in the bath product industry. However, bath oil products also have certain drawbacks.

[0003] Existing bath oil technology mainly uses oils, detergents, and emulsifiers to prepare bath oil products, claiming to have excellent moisturizing effects and be gentle and non-irritating. However, it contains a relatively high amount of detergents and oils. Although it has both moisturizing and cleansing effects, the two effects conflict. In addition, the amount of foam is small, and the cleansing feeling is not refreshing enough, which cannot meet the product needs of today's young people.

[0004] Therefore, there is an urgent need for a bath oil that not only has excellent moisturizing effects, but also excellent foam production and gentle, refreshing cleansing effects. Summary of the Invention

[0005] The present invention addresses the above-mentioned problems by providing a transparent, moisturizing, multi-foaming bath oil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution, the composition and weight ratio of which are: glycerin 40%, oil 0-10%, surfactant 2-20%, sorbitol 3%, fragrance 0.2%-2%, preservative 0.4%, and the remainder being deionized water.

[0007] The oil is one or more of the following: camellia seed oil, babassu seed oil glycerol polyether-8 ester, PEG-7 glycerol cocoate, and PEG-120 methyl glucotrioleate.

[0008] The surfactant is one or more of the following: cocamidopropyl betaine, decyl glucoside, lauroyl sarcosine, and rapeseed oil-amylpropyl dimethylamine.

[0009] The preservative mentioned is phenoxyethanol.

[0010] The surfactant composition and weight ratio (as a percentage of the bath oil weight) are as follows: cocamidopropyl betaine 1.5%–6%, decyl glucoside 0%–7.725%, sodium lauroyl sarcosinate 0%–3%, and rapeseed oil amide propyl dimethylamine 0.5%.

[0011] The preparation steps are as follows: (1) Add glycerin and oil to the mixing bowl and stir. Heat to 60-80°C until completely dissolved. (2) Cool down to 40-50℃, and add surfactant, sorbitol, preservative and flavoring in sequence while stirring. Stir until well mixed.

[0012] The beneficial effects of this invention are: This invention, by selecting a specific ratio of glycerin, oils, and surfactants, effectively increases the amount of foam produced in bath oil while providing excellent cleansing performance and a refreshing feel, while maintaining excellent moisturizing properties and gentleness. The combination of glycerin and oils reduces the greasiness of the oils while maintaining the moisturizing and nourishing properties of the bath oil, and at the same time reduces the defoaming effect caused by excessive oil, thus reducing the loss of sebum. Therefore, it provides a user experience similar to ordinary shower gel while effectively improving moisturizing and gentleness.

[0013] This invention has a good cleaning effect, and while ensuring excellent cleaning effect, it also has good foam production and moisturizing properties, with comprehensive performance, which can effectively meet the current needs of young people for bath products.

[0014] This product has high stability and is easy to promote and apply. Detailed Implementation

[0015] Example 1 Add 40 kg of glycerin, 0.0001 kg of camellia seed oil, 0.5 kg of babassu seed oil glycerol polyether-8 ester, and 3 kg of PEG-7 glycerol cocoate to the mixing bowl and stir until homogeneous. Then add 0.21 kg of PEG-120 methyl glucotrioleate and heat to 60-80°C until completely dissolved. Cool to 40-50°C and while stirring, add 3 kg of sorbitol, 4.5 kg of cocamidopropyl betaine, 5.15 kg of decyl glucoside, 1.8 kg of sodium lauroyl sarcosinate, 0.5 kg of rapeseed oil ammonium dimethylamine, 0.4 kg of phenoxyethanol, and 1 kg of magnolia fragrance in sequence. Add deionized water to make the total weight of the mixture 100 kg and stir until homogeneous.

[0016] Comparative Example 1 The difference from Example 1 is that the amount of glycerol added is 5 kg, 11.2 kg of sodium lauryl ether sulfate is used instead of sodium lauroyl sarcosinate, and decyl glucoside is not added.

[0017] Comparative Example 2 The difference from Example 1 is that the amount of sodium lauroyl sarcosinate added is 3 kg.

[0018] Comparative Example 3 The difference from Example 1 is that the amount of sodium lauroyl sarcosinate added is 0.9 kg.

[0019] Comparative Example 4 The difference from Example 1 is that decyl glucoside is not added.

[0020] Comparative Example 5 The difference from Example 1 is that the amount of decyl glucoside added is 7.725 kg.

[0021] Comparative Example 6 The difference from Example 1 is that the amount of cocamidopropyl betaine added is 6 kg.

[0022] Comparative Example 7 The difference from Example 1 is that the amount of cocamidopropyl betaine added is 1.5 kg.

[0023] Performance Evaluation I. The foam volume of the bath oils prepared in the examples and comparative examples was tested using a Roche foam meter.

[0024] The testing method is as follows 1. Take 2.5g of the sample and add 100mL of hard water and 900mL of pure water to a beaker; 2. Heat to 41℃ and stir to dissolve the sample evenly; 3. Use a 200mL quantitative funnel to draw up a portion of the test solution and rinse it along the wall of the foam apparatus tube; 4. Take another sample of the test solution and place it at the bottom of the foam apparatus, aligning it with the standard graduation mark to 50 mL; 5. Use a 200mL quantitative funnel to draw up a portion of the test solution, fix the center of the funnel, and then lower the test solution. 6. Record the highest and lowest values ​​of the bubble; 7. Repeat twice and take the average.

[0025] Test equipment: Roche foam tester, electronic scale, graduated cylinder, thermometer, super thermostat, beaker.

[0026] The measured results are recorded in Table 1.

[0027] Table 1 Start 5 minutes later Example 1: Foam Height (mm) 101 96 Comparative Example 1: Foam Height (mm) 125 120 Comparative Example 2: Foam Height (mm) 110 105 Comparative Example 3: Foam Height (mm) 100 95 Comparative Example 4: Foam height (mm) 91 86 Comparative Example 5: Foam Height (mm) 110 105 Comparative Example 6: Foam height (mm) 109 104 Comparative Example 7: Foam Height (mm) 95 90 As shown in Table 1, the shower gel containing AES in Comparative Example 1 has slightly higher foaming rate. The shower oil products in Example 1 and the other comparative examples are similar to those in Comparative Example 1, indicating that the foaming ability of the shower oils in Example 1 and Comparative Examples 2, 3, 4, 5, 6, and 7 is close to that of conventional products on the market.

[0028] II. Moisturizing Test Testing instrument: Corneometer (stratum corneum moisture content testing probe) Test method: Take 20 μL of sample and add 1 mL of water. Slowly and evenly massage the sample with your fingers in 20 circles to create foam. Rinse with water while simultaneously massaging in circles with your fingers for 5 circles. Use a Corneometer CM825 to test the stratum corneum moisture content of the test area before use, 1 hour after use, 2 hours after use, 3 hours after use, and 4 hours after use. Record the measured skin moisture content in Table 2.

[0029] Table 2 Before rinsing 1 hour later 2 hours later 3 hours later 4 hours later Example 1 24.94 24.81 24.82 26.92 24.57 Comparative Example 1 23.72 21.99 23.68 23.77 23.31 Comparative Example 2 22.59 21.96 22.43 22.26 23.01 Comparative Example 3 26.69 26.26 26.46 26.36 27.04 Comparative Example 4 26.25 26.57 28.09 28.22 28.09 Comparative Example 5 27.71 26.24 27.08 27.53 28.76 Comparative Example 6 23.18 25.16 25.19 26.29 25.8 Comparative Example 7 28.52 28.88 28.72 30.42 25.8 Table 2 shows that the moisture content of Comparative Example 1 (AES shower gel) decreased slightly after washing. In the other examples and comparative examples, the moisture content remained high before and after use, and the moisturizing effect remained within normal limits. This demonstrates that shower oil products have stronger moisturizing capabilities than shower gels.

[0030] III. Transdermal water loss test Test procedure: Take 20 μL of sample and add 1 mL of water. Slowly and evenly massage the sample with your fingers in 20 circular motions to create foam. Rinse with water while simultaneously massaging in circular motions with your fingers for 5 times. Use a Tewameter to test the TEWL values ​​of the test area before rinsing, 1 hour after use, 2 hours after use, 3 hours after use, and 4 hours after use. Record the results in Table 3.

[0031] Table 3 Before rinsing 1 hour later 2 hours later 3 hours later 4 hours later Example 1 9.9 9.3 9.31 9.61 9.6 Comparative Example 1 10.21 10.63 10.54 10.66 10.69 Comparative Example 2 10.36 10.2 9.89 10.34 10.4 Comparative Example 3 11.03 10.55 10.65 10.58 10.71 Comparative Example 4 9.42 9.06 8.72 8.66 8.8 Comparative Example 5 9.74 9.68 8.99 8.73 8.72 Comparative Example 6 9.31 8.8 9.11 8.74 8.5 Comparative Example 7 9.98 9.22 9.02 8.92 8.67 As shown in Table 3, the TEWL value of Comparative Example 1 (AES shower gel) increased slightly before and after washing, while the values ​​of the other comparative examples and examples were lower. This demonstrates that the shower oils in Examples and Comparative Examples 2, 3, 4, 5, 6, and 7 resulted in less transdermal water loss, had less negative impact on skin moisturizing, and exhibited high gentleness.

[0032] Analysis of Examples 1, Comparative Examples 1-7, and Tables 1-3 shows that the bath oil of the present invention, while possessing good cleansing and moisturizing properties, also exhibits excellent foam production, approaching that of common sodium lauryl ether sulfate bath gels. Furthermore, it effectively improves the mildness of the bath oil, making it suitable for promotion in the bath products field and possessing broad development prospects. Example 1, in particular, achieved the best performance index under optimal raw material ratios.
