Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and particularly relates to a sunscreen lipstick and a preparation method thereof. Background Art

[0002] The ultraviolet bands in sunlight that are damaging to the skin include short-wave UVB (290-320nm) and long-wave UVA (320-400nm). UVB can cause immediate damage to the skin such as erythema and sunburn, while UVA can penetrate into the dermis and cause photoaging and even lesions of the skin.

[0003] Chemical sunscreens, also known as organic sunscreens, are a type of organic compound that has a good absorption effect on ultraviolet rays. Chemical sunscreens have high sunscreen efficiency, but poor stability. Direct use will irritate the skin and even have the risk of penetrating the skin. The sunscreen is dispersed in the oil phase to participate in the formulation of sunscreen products. Not only does it feel sticky on the skin, but it also has poor stability. At present, there is an urgent need for a combination of oils and fats that has a good skin feel and helps the sunscreen to disperse, thereby increasing the SPF value, which can be used in lipstick products.

The results are shown in Table 1.

[0022] Table 1 Optimization of antioxidant hydroponic oil composition

[0023] The results showed that when the ratio of sea buckthorn seed oil: meadowfoam seed oil: rosehip oil was 9:0.5:0.5 or 7:2:1, the antioxidant property of the obtained hydroponic oil was the best, and the DPPH free radical scavenging rate could reach more than 90%.

[0024] Example 2 Preparation of Soothing and Repairing Hydroponic Oil The soothing and repairing hydroponic oil is obtained by mixing sunflower seed oil, sweet almond oil and prune nut oil and fermenting them. The specific process is as follows: S1. Inoculate lactobacillus into seed culture medium containing 10 g / L glucose and 20 g / L rice; culture at 30°C for 12 h after inoculation. S2, inoculate the seed liquid cultured in S1 into the fermentation medium for cultivation, the fermentation medium is: glucose 20g / L, yeast extract 10g / L, rice 20g / L; after culturing at 30℃ for 12h, add an equal volume of sunflower seed oil, sweet almond oil, and prune oil mixed oil, and continue fermentation and cultivation for 24h; S3. After the fermentation is completed, centrifuge and take the upper oil phase to obtain the antioxidant hydroponic oil.

[0025] In order to obtain the hydroponic oil with the best soothing and repairing effect, the addition ratio of sunflower seed oil, sweet almond oil and prickle oil during the fermentation process was optimized, and a total of ten groups of ten ratios were designed: Experimental group 1: sunflower seed oil: sweet almond oil: prickle oil = 9:0.5:0.5; Experimental group 2: sunflower seed oil: sweet almond oil: prickle oil = 7:2:1; Experimental group 3: sunflower seed oil: sweet almond oil: prickle oil = 5:3:2; Experimental group 4: sunflower seed oil: sweet almond oil: prickle oil = 3.3:3.3:3.4; Experimental group 5: sunflower seed oil: sweet almond oil: prickle oil = 3:5:2; Experimental group 6: sunflower seed oil: sweet almond oil: prickle oil = 2:7:1; Experimental group 7: sunflower seed oil: sweet almond oil: prickle oil = 0.5:9:0.5; Experimental group 8: sunflower seed oil: sweet almond oil: prickle oil = 2:3:5; Experimental group 9: sunflower seed oil: sweet almond oil: prickle oil = 1:2:7; Experimental group 10: sunflower seed oil: sweet almond oil: prickle oil = 0.5: 0.5: 9; The soothing and repairing effects were evaluated by detecting the content of inflammatory factors (TNF-α, IL-1α) in macrophage RAW264.7 cells stimulated by LPS, and the optimal oil composition was determined by measuring the soothing and repairing properties of the obtained hydroponic oil. Figure 1 As shown, BC is normal cells, NC is cells treated with LPS stimulation, and PC is the positive control group treated with 100 μg / mL dexamethasone.

[0026] The results showed that when the ratio of sunflower seed oil: sweet almond oil: prickle oil was 5:3:2, the resulting hydroponic oil had the best soothing and repairing effect.

[0027] Example 3 A sunscreen lipstick comprises the following components in percentage by mass: 0.5% antioxidant hydroponic oil, 0.5% soothing and repairing hydroponic oil, 17% water, 10% tri(octyldodecanol) citrate, 9% synthetic wax, 8% octocrylene, 8% bis-diglyceryl polyacyl adipate-2, 7% homosalate, 5% ethylhexyl stearate, 5% ethylhexyl salicylate, 5% glycerin, 5% 1,3-propylene glycol, 4% isooctyl palmitate, 4% caprylic / capric triglyceride, 3% butyl methoxydibenzoylmethane, 1.5% shea butter, 0.5% sodium chloride, 0.5% hexylene glycol, and 0.5% p-hydroxyacetophenone.

[0034] Performance Testing 1. SPF test of the samples of Examples 3-6 and Comparative Examples 1-2 The test method is based on applying lipstick on a PMMA board, irradiating it with ultraviolet rays of different wavelengths, and then testing the absorbance of the sample to directly evaluate the sunscreen effect of the product based on the test value. Figure 2 shown.

[0035] The results showed that different amounts of hydroponic oil added affected the SPF value of the lipstick. The lipstick with 0.5% antioxidant hydroponic oil and 0.5% soothing and repairing hydroponic oil had the highest SPF value, and the lipstick with 0.5% antioxidant hydroponic oil and soothing and repairing hydroponic oil had the best sun protection effect.

[0036] 2. Carry out texture fracture test on the samples of Examples 3-6 and Comparative Examples 1-2.

[0037] Test method: 6 samples were tested for fracture. The probe was TA-LC. During the test, the lipstick was fixed on the fixture, the descending speed was set to 1mm / s, the descending time was set to 10s, and the fracture test was performed. The fracture test results of the lipstick texture are as follows: Figure 3 shown.

[0038] The results showed that the amount of hydroponic oil added affected the hardness of the lipstick. The lipstick with 1% antioxidant hydroponic oil and 1% soothing and repairing hydroponic oil had the highest hardness and the best anti-fracture ability.

[0039] 3. The texture smoothness of the samples of Examples 3-6 and Comparative Examples 1-2 was tested.

[0040] Test method: Compression test was performed on 6 samples. The test mode was TPA mode, the probe was TA43, the target was 100 mm, the pre-test speed was 2 mm / s, the trigger point load was 0 g, the test speed was 1 mm / s, and the return speed was 5 mm / s. During the test, the probe moved downward at the pre-test speed and began to collect data. Using double-sided silicone rubber, 0.05 g of the material was evenly applied to a circle with a radius of 2 cm, and the data was collected after waiting for 10 minutes. This method is defined as a smoothness test (the friction of the test sample at different times). The smoothness test results of the lipstick are as follows: Figure 4 shown.

[0041] The results showed that different amounts of hydroponic oil added affected the smoothness of the lipstick. The lipstick with 3% antioxidant hydroponic oil and 3% soothing and repairing hydroponic oil had the lowest friction, that is, the highest smoothness and was able to maintain a moisturizing feel.

[0042] However, for lipstick, if the hardness is high and the friction is large, it will make it difficult to apply. If the hardness is low and the friction is small, the paste is too soft, which will also affect the application. Therefore, the hardness and friction requirements of the paste cannot be too high or too low.

[0043] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
