Description

TECHNICAL FIELD

[0001] The present application relates to the field of daily chemical technology, in particular to a mousse type sunscreen cosmetic composition and a preparation method thereof. BACKGROUND

[0002] Sunscreen agents with mousse texture are lightweight sunscreen products that present a cream-like texture, giving users a refreshing and non-greasy use experience. The advantage of mousse sunscreen agents lies in their ease of application, rapid absorption, comfort and suitability for oily or mixed skin. Since sunscreen agents need to be maintained on the surface of the skin to form an effective protective layer, in addition to the lightness, the stability of sunscreen ingredients, the protection effect and the adaptability of the skin also need to be considered when designing sunscreen agents with mousse texture.

[0003] Sunscreen agents with mousse texture are suitable for various skin types, especially oily skin and summer use. They do not bring a heavy or greasy feeling to the skin, and can bring a breathable and refreshing feeling. The biggest feature of mousse texture sunscreen agents is that it is very easy to expand when applied, and can be evenly applied to the surface of the skin. Sunscreen ingredients can quickly form a protective layer on the skin without blocking pores or causing discomfort.

[0004] The absorption of organic sunscreen agents varies with different skin types. For example, oily skin may absorb oil-soluble sunscreen agents faster, while dry skin may need to add moisturizing ingredients to improve absorption. High-efficiency sunscreen agents may affect the smoothness of mousse application. If the sunscreen agent is too greasy or has large particles, it may cause a dragging or sticky feeling when applied. Sunscreen agents need to be evenly distributed in the formula, especially physical sunscreen agents, whose particles must be stably suspended in the foaming base to avoid sedimentation or stratification. It is a technical challenge to maintain the effectiveness of sunscreen agents while maintaining the mousse texture, especially in preparation to avoid damaging the sunscreen function of active ingredients.

[0038] (4) The extract prepared in step (3) is separated to obtain a supernatant; then the supernatant is added with three volumes of ethanol, the precipitate is separated, and the supernatant is taken to obtain the FOMES OFFICINALIS extract.

[0039] As a preferred mode of the present application, the preparation method of the GENTIANA SCABRA root extract is as follows:

[0040] The GENTIANA SCABRA root powder is mixed with 70% ethanol at a ratio of 1:10 (mass / volume ratio) (i.e. 100 grams of powder is added to 1000 mL of 70% ethanol solution).

[0041] The mixture is placed in an ultrasonic instrument for ultrasonic extraction, with the ultrasonic power set to 300 W for 30 minutes, and the temperature controlled at 60°C. After extraction, the extract is cooled to room temperature.

[0042] The solution after extraction is filtered to remove residues, and concentrated under reduced pressure at 45°C until the volume is reduced to 1 / 5 of the original volume; then the extract is freeze-dried to obtain the GENTIANA SCABRA root extract.

[0043] As an embodiment of the present application, the preparation method of the mousse-type sunscreen agent is as follows:

[0044] (1) The A-phase raw materials are pre-soaked and dispersed to a uniform state, ready for use;

[0045] (2) The B-phase raw materials are added to a vacuum emulsifying pot, stirring is started, and heating is performed to 75-80°C, then the A-phase is added, vacuum is applied, homogenization is performed for 5 min, the mixture is checked for completeness, and the temperature is maintained for 5-10 min;

[0046] (3) The C-phase raw materials are added to an oil pot, stirring is started, and the temperature is raised to 80-85°C, maintained for 3-5 min, then added to the emulsifying pot, homogenization is performed for 5-7 min, the mixture is cooled after the material is uniform and there are no particles;

[0047] (4) When the temperature drops to 45°C, the D-phase raw materials are added, homogenization and stirring are performed for 3 min, vacuum is applied to remove foam, and the temperature is lowered

[0048] (5) The temperature is lowered to 35-38°C, and the mixture is checked for quality, then filtered through a 200-mesh sieve. Sampling is performed, and the material is transferred;

[0049] (6) After quality inspection, the mixture is filled and packaged, and the finished product is stored in the warehouse after quality inspection.

[0050] Among them, the:

[0051] The A-phase raw materials are 1 / 3 parts of water, sodium polyacrylate, potassium cetyl phosphate, and acrylate / C10-30 alkyl acrylate crosspolymer;

[0052] The B-phase raw materials are the remaining water, butylene glycol, glycerol polyether-26, and p-hydroxyacetophenone;

[0053] Phase C raw materials: ethylhexyl methoxycinnamate, butylated hydroxytoluene, diethylamino hydroxybenzoyl hexyl benzoate, cetyl alcohol, glyceryl stearate, PEG-75 stearate, cetyl peg-20, steareth-20, ethylhexyl palmitate, ethylhexyl triazone, isononyl isononanoate, dimethicone, sorbitan oleate, silica, tocopheryl acetate, bis-ethylhexyloxyphenol methoxyphenyl triazine;

[0054] Phase D raw materials: remaining raw materials.

[0055] The mousse sunscreen has high requirements for the ratio of emulsifier, water phase and oil phase, and the different types of sunscreen used in the sunscreen product can destroy the balance among the emulsifier, water phase and oil phase. The mousse sunscreen provided by the present application is quickly absorbed, and thus it can be a little dry for dry skin. Therefore, the oat kernel extract is added in the formula to provide a moisturizing film feeling, so that the dry skin can achieve better moisturizing. Meanwhile, the FOMES OFFICINALIS extract is additionally added in the formula to obtain a mousse texture with relatively stable performance. On the one hand, the polysaccharide component contained in the FOMES OFFICINALIS extract can improve the consistency and thus improve the stability. The FOMES OFFICINALIS extract is rich in polysaccharides and polyphenols, and has strong antioxidant capacity and can neutralize free radicals, thereby reducing the damage of ultraviolet rays or environmental pollution to the skin. When the FOMES OFFICINALIS extract is added in the sunscreen mousse, the skin care performance of the product can be improved, and additional skin protection can be provided. However, the FOMES OFFICINALIS extract is sensitive to pH, and thus in the long run, it can affect the stability of the mousse texture. Therefore, the GENTIANA SCABRA root extract and octyl dodecyl phenyl triazole are added to realize the stability and absorption of oily sunscreen.

[0056] Meanwhile, the water phase and the oil phase are stably mixed together according to the preparation process, and are not prone to delamination and separation even under humid and long-term storage conditions.

[0177] Test 3: Determination of SPF value of sunscreen cosmetic

[0178] Materials and methods

[0179] 1. Test substance: Examples 1-6.

[0180] 2. Control: SPF value 20.1±2.4, prepared according to the standard formulation of high SPF standard (P2) in the "Cosmetic Safety Technical Specification" (2015 edition).

[0181] 3. Subjects: A total of 26 people, 1 man and 25 women, aged 25-45 years, with an average age of 32.1±2.6 years, who met the voluntary selection criteria for subjects.

[0182] 4. Light source: Sunlight simulator xenon arc lamp, with performance indicators meeting the requirements of the determination specification.

[0183] 5. Test method: The test was conducted according to the specific requirements of the “Cosmetic Safety Technical Specifications” (2015 edition). The subjects were in a prone position, and their backs were irradiated. The minimum erythema dose (MED value) of the subjects' skin to ultraviolet irradiation was predicted 24 hours before the test, and the ultraviolet irradiation dose was adjusted according to the prediction results for the test of the measured object. On the test day, a normal skin area of not less than 30 cm 2 was first selected on the back of the subject, and the measured object or the control was uniformly applied to the above-mentioned area at a dosage of (2.00 ± 0.05) mg / cm 2 , and then the irradiation dose was selected according to the requirements of the specifications, and irradiation was performed in three cases: ① the skin of the subject was not coated with the measured object; ② the control was coated; and ③ the measured object was coated. The experimental results were observed after 24 hours, and the MED values in the three cases were recorded, respectively.

[0184] 6. SPF value calculation method: The SPF value of the measured object or the control for protecting a single subject was represented by the following formula:

[0185] SPFi = MED value of protected skin / MED value of unprotected skin * 100%

[0186] The individual SPF value was required to be accurate to one decimal place, and the arithmetic mean of the SPF value of the measured object for protecting all subjects was taken as the integer part, which was the SPF value of the measured sample. The sampling error of the estimated mean could be calculated as the standard deviation and the standard error. The 95% confidence interval (95% CI) of the mean was required to be not more than 17% of the mean, otherwise the number of subjects should be increased (not more than 25) until the above requirements were met.

[0192] 3. Subjects: A total of 26 people, 1 male and 25 females, aged 25-45 years, with an average age of 32.1 ± 2.6 years, meeting the subject's voluntary selection criteria.

[0193] 4. Light source: Sunlight simulator xenon arc lamp, with performance indicators meeting the requirements of the determination specifications

[0194] 5. Test method: The test was performed according to the requirements of the "Cosmetic Safety Technical Specifications" (2015 edition). The subjects were in a prone position, and their backs were irradiated. The minimum pigmentation dose (MPPD value) of the subjects' skin to ultraviolet irradiation was predicted 24 hours before the test, and the amount of ultraviolet irradiation was adjusted according to the prediction results for the test of the measured object. The test first selected a normal skin area of not less than 30 cm 2 on the back of the subject, and then uniformly applied the measured object or the control product in an amount of (2.00 ± 0.05) mg / cm 2 on the above area; then selected the UVA irradiation amount according to the requirements of the specification, and irradiated in three cases: ① the subject's skin without the measured object; ② with the control product; and ③ with the measured object. The experimental results were observed after 2-4 hours, and the MPPD values under the three conditions were recorded.

[0195] 6. Calculation method of PFA value: The PFA value of the measured object or the control product to protect a single subject was represented by the following formula:

[0196] PFAi = MPPD value of protected skin / MPPD value of unprotected skin * 100%

[0197] The individual PFA value was required to be accurate to one decimal place, the arithmetic mean of the PFA values of the measured object to protect all subjects was calculated, and the integer part was the PFA value of the measured sample. The sampling error of the estimated mean could be calculated by the standard deviation and the standard error, and the 95% confidence interval (95% CI) of the mean was required to be not more than 17% of the mean, and the number of subjects was increased until the above requirements were met, but the maximum number of subjects was 25.
