Description

Technical Field

[0001] The invention relates to the technical field of daily chemicals, in particular to a sunscreen with a cream texture and application thereof. Background Art

[0002] At present, oil-based cream-textured sunscreens are a type of skin care sunscreen product that has no water phase ingredients and is completely composed of oil phase and oil-soluble ingredients.

[0003] Since there is no water phase, the pure oil system has excellent water and sweat resistance, making it very suitable for high humidity environments and water activities, providing long-lasting sun protection. Oily ingredients provide long-lasting moisturizing effects to the skin, helping to lock in moisture, suitable for dry skin and skin that needs additional barrier protection. The absence of a water phase reduces the risk of microbial growth, making the formula more stable, less susceptible to bacteria and mold, and reducing the need for preservatives. The creamy texture combines softness and smoothness, is easy to apply and can evenly cover the skin surface without leaving a heavy residue.

[0004] Products with pure oil systems may leave a greasy feeling when used and are not suitable for users who prefer a refreshing texture, especially those with oily and combination skin. Oily formulas may form a film on the skin, reducing the skin's breathability, and long-term use may cause skin discomfort or acne. Compared with lotion or cream sunscreens, pure oil systems usually take longer to be absorbed by the skin and may remain on the skin surface for a period of time. Some pure oil formulas may appear thicker and may make the skin feel heavier when used in hot weather. Due to its high water resistance and oily ingredients, pure oil sunscreens may need to be completely removed with a special cleanser or cleansing oil when removing makeup, otherwise it is easy to cause pores to clog. Although the full oil system helps the photostability of some sunscreens, not all organic sunscreen ingredients can maintain good stability in a pure oil matrix, and additional antioxidants or photostabilizers may be required.

[0219] Determination of SPF value of sunscreen cosmetics

[0220] Materials and methods

[0221] 1. Measured objects: Examples 1, 3 to 7.

[0222] 2. Reference substance: SPF value 20.1±2.4, prepared in accordance with the standard formula of medium and high SPF standard product (P2) in the "Technical Specification for Safety of Cosmetics" (2015 edition).

[0223] 3. Subjects: A total of 32 people, including 8 males and 24 females, aged 25 to 45 years old, with an average age of 28.9±3.32 years old, met the voluntary inclusion criteria.

[0224] 4. Light source: Daylight simulator xenon arc lamp, all performance indicators meet the measurement specification requirements.

[0225] 5. Test method: Test in accordance with the specific requirements of the "Technical Specifications for Safety of Cosmetics" (2015 edition). The subject lies prone and the back is irradiated. The minimum erythema dose (MED value) of the subject's skin to ultraviolet radiation is predicted 24 hours before the test, and the ultraviolet radiation dose is adjusted according to the predicted results for testing the test object. On the day of the test, a spot no less than 30 cm is selected on the subject's back. 2 Normal skin area, (2.00±0.05)mg / cm 2 The test object or reference substance is evenly applied to the above area with the dosage of 100 mg / kg, and then the irradiation dose is selected according to the specification requirements. The irradiation is carried out in three conditions: ① The test object is not applied to the subject's skin; ② The reference substance is applied; ③ The test object is applied. Observe the experimental results after 24 hours and record the MED values ​​in the three conditions respectively.

[0226] 6. SPF value calculation method: The SPF value of the test article or reference article for protecting a single subject is expressed as follows:

[0227] SPFi = MED value of protected skin / MED value of unprotected skin * 100%

[0228] The individual SPF value is required to be accurate to one decimal place. The arithmetic mean of the SPF values ​​of all subjects protected by the measured object is taken as the integer part, which is the SPF value of the measured sample. The sampling error of the estimated mean can calculate the standard deviation and standard error of the data set. The 95% confidence interval (95% CI) of the mean is required to not exceed 17% of the mean, otherwise the number of subjects should be increased (not more than 25) until the above requirements are met.

[0237] 5. Test method: Test in accordance with the specific requirements of the "Technical Specifications for Safety of Cosmetics" (2015 edition). The subject lies prone and the back is exposed to the radiation. The minimum amount of darkening of the subject's skin to ultraviolet radiation (MPPD value) is predicted 24 hours before the test, and the amount of ultraviolet radiation is adjusted according to the predicted results for testing the test object. The test first selects an area of ​​no less than 30cm on the subject's back. 2 For normal skin area, (2.00±0.05)mg / cm 2 The test object or reference product is evenly applied to the above area with the dosage; then the UVA exposure amount is selected according to the specification requirements, and the exposure is carried out in three conditions: ① The test object is not applied to the test object; ② The reference product is applied; ③ The test object is applied. Observe the experimental results after 2 to 4 hours, and record the MPPD values ​​in the three conditions respectively.

[0238] 6. Calculation method of PFA value: The PFA value of the test substance or reference substance protecting a single subject is expressed as follows:

[0239] PFAi = MPPD value of protected skin / MPPD value of unprotected skin * 100%

[0240] Individual PFA values ​​are required to be accurate to one decimal place. The arithmetic mean of the PFA values ​​of all subjects of the measured object protection is calculated, and the integer part is the PFA value of the measured sample. The sampling error of the estimated mean can calculate the standard deviation and standard error of the group of data. The 95% confidence interval (95% CI) of the mean is required to be no more than 17% of the mean.
