Description

Technical Field

[0001] This invention relates to the field of daily chemical technology, and in particular to a sunscreen with a creamy texture and its application. Background Technology

[0002] Currently, oil-based cream-textured sunscreens are a type of skincare sunscreen product that contains no aqueous phase components and consists entirely of oil phase and oil-soluble ingredients.

[0003] Because it contains no aqueous phase, the pure oil system offers excellent water and sweat resistance, making it ideal for high-humidity environments and water activities, providing long-lasting sun protection. The oil components provide long-lasting hydration, helping to lock in moisture, making it suitable for dry skin and skin requiring extra barrier protection. The absence of an aqueous phase reduces the risk of microbial growth, making the formula more stable and less susceptible to bacteria and mold, thus reducing the need for preservatives. The creamy texture combines softness and smoothness, making it easy to apply and evenly cover the skin without leaving a heavy residue.

[0004] Pure oil-based products may leave a greasy feeling after application, making them unsuitable for users who prefer a lighter texture, especially those with oily or combination skin. Oily formulas may form a film on the skin, reducing its breathability, and long-term use may lead to skin discomfort or breakouts. Compared to lotion or cream-based sunscreens, pure oil systems generally require more time to be absorbed and may remain on the skin's surface for some time. Some pure oil formulas may feel heavy, potentially causing a burden on the skin in hot weather. Due to their high water resistance and oil content, pure oil sunscreens may require a dedicated cleanser or makeup remover for thorough removal, otherwise, they can easily clog pores. While all-oil systems contribute to the photostability of some sunscreens, not all organic sunscreen ingredients maintain good stability in a pure oil base, and additional antioxidants or photostability agents may be necessary.

[0005] In view of this, the present invention provides a sunscreen with a milk cream texture and its application. Summary of the Invention

[0222] 2. Reference standard: SPF value 20.1±2.4, prepared according to the standard formula of high SPF standard (P2) in the "Cosmetic Safety Technical Specifications" (2015 edition).

[0223] 3. Subjects: A total of 32 subjects, including 8 males and 24 females, aged 25 to 45 years, with a mean age of 28.9 ± 3.32 years, who met the subject voluntary inclusion criteria.

[0224] 4. Light source: Xenon arc lamp from a daylight simulator, with all performance indicators meeting the requirements of the testing specifications.

[0225] 5. Testing Method: The testing was conducted according to the specific requirements of the "Cosmetic Safety Technical Specifications" (2015 edition). Subjects were placed in a prone position, and their backs were irradiated. The minimum erythema dose (MED) of the subject's skin to ultraviolet radiation was predicted 24 hours prior to the test, and the ultraviolet radiation dose was adjusted based on the prediction result for testing the test substance. On the day of the test, a spot no less than 30cm long was first selected on the subject's back. 2 In normal skin areas, at (2.00±0.05) mg / cm² 2 Apply the test substance or control evenly to the above-mentioned area, and then select the irradiation dose according to the standard requirements. Irradiation is carried out under three conditions: ① no test substance applied to the subject's skin; ② control substance applied; ③ test substance applied. Observe the experimental results after 24 hours and record the MED values ​​under each of the three conditions.

[0226] 6. SPF Value Calculation Method: The SPF value of the analyte or control for protecting a single subject is expressed by the following formula:

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

[0228] Individual SPF values ​​must be accurate to one decimal place. The SPF value of the sample is the integer part of the arithmetic mean of the SPF values ​​of all subjects tested. The sampling error of the mean can be estimated by calculating the standard deviation and standard error of the data set. The 95% confidence interval (95% CI) of the mean should not exceed 17% of the mean; otherwise, the number of subjects should be increased (not exceeding 25) until the above requirement is met.

[0236] 4. Light source: Xenon arc lamp from a daylight simulator; all performance indicators meet the requirements of the testing specifications.

[0237] 5. Test Method: The test was conducted according to the specific requirements of the "Cosmetic Safety Technical Specifications" (2015 edition). The subject was placed in a prone position, and their back was irradiated. The minimum melanization potential (MPPD) of the subject's skin to ultraviolet radiation was predicted 24 hours prior to the test, and the ultraviolet radiation dose was adjusted based on the prediction result for testing the test substance. The test was first conducted by selecting a spot at least 30cm long on the subject's back. 2 For normal skin areas, administer (2.00±0.05) mg / cm². 2 Apply the test substance or control evenly to the above-mentioned area; then select the UVA irradiation dose according to the standard requirements and irradiate under three conditions: ① no test substance applied to the subject's skin; ② application of control; ③ application of test substance. Observe the experimental results after 2-4 hours and record the MPPD values ​​under each of the three conditions.

[0238] 6. Calculation method of PFA value: The PFA value of the analyte or control for protecting a single subject is expressed by the following formula:

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

[0240] Individual PFA values ​​must be accurate to one decimal place. Calculate the arithmetic mean of the PFA values ​​of all subjects using the tested material protection, and take the integer part as the PFA value of that sample. The sampling error of estimating the mean can be calculated by calculating the standard deviation and standard error of the data set. The 95% confidence interval (95% CI) of the mean must not exceed 17% of the mean. Increase the number of subjects until the above requirement is met, but the number should not exceed 25.
