Sunscreen foundations, as a high-end cosmetics category, are marketed with core selling points such as “high coverage, lightweight feel, and long-lasting sun protection.” Their formulations are more complex, involving a higher proportion of foundation powder, oil control ingredients, long-lasting film-forming agents, and sunscreen agents, with significant interactions between these components. The stability and longevity of sun protection effectiveness are core challenges in product development. The CHNSpec SPF-600/620/660 series Cosmetics Sun Protection Factor (SPF) Analyzers, with their full-spectrum detection, high anti-interference capabilities, and real-world scenario-based design, precisely meet the testing needs of sunscreen foundations. They provide professional data support for the research and quality control of high-end sunscreen foundations. The R&D and testing of sunscreen foundations face three core challenges: First, the scattering and absorption of UV radiation by the foundation's powder components often interfere with the actual efficacy of the sunscreens, leading to distorted test data. Second, the presence of long-lasting film-forming agents results in significant discrepancies between the SPF performance of the sample once the film has set and its performance in the wet, undried state. Third, the demand for High-Energy Visible Light (HEVIS) protection in high-end products necessitates coverage across a much broader spectral range. Addressing these pain points, Caipu has developed a specialized testing solution: the SPF-660 analyzer. Covering the full 280–500 nm spectrum, this model simultaneously evaluates protection against UVB, UVA, and HEVIS, thereby meeting the comprehensive, full-spectrum testing requirements of high-end SPF liquid foundations. Furthermore, its "instantaneous full-spectrum capture" technology—combined with a high signal-to-noise ratio design—effectively filters out signal interference caused by powder scattering, enabling the precise extraction of the sunscreens' actual protective data and the elimination of testing errors. In actual use, the application amount of sunscreen foundation is much lower than that of pure sunscreen, and it must be patted and spread to form an even thin film. Its sun protection performance highly depends on the state after film formation. The CHNSpec SPF series analyzers, together with standardized PMMA testing plates, simulate the coating and film-forming process on the skin’s surface. Samples are prepared according to the actual usage amount of the cosmetic product, left to form a film, and then tested. This process provides data that is closer to the real-life usage scenario of consumers. Additionally, the instrument’s low UV radiation dose (less than 0.2J/cm²) design avoids damage to the film-formed sample during testing, accurately restoring the long-lasting sun protection effect of the sunscreen foundation, providing precise data to help researchers optimize film-forming agent formulations and improve sun protection longevity. In the development of high-end sunscreen foundations, “full-spectrum protection” has become a core trend. In addition to the basic SPF and UVA-PF indicators, protection against high-energy visible light (HEVIS) has become a key differentiating factor for products. The CHNSpec SPF-660 model exclusively supports HEVIS indicator testing, accurately analyzing the product’s protection effect against high-energy visible light in the 400–500nm range. This enables companies to create sunscreen foundations that offer “UV + blue light” full protection, aligning with the needs of the high-end market. The instrument can also test critical wavelength, UVA/UVB ratio, and other indicators to quickly verify the broad-spectrum sun protection credentials of the product, providing scientific and compliant data support for high-end product claims. As a sunscreen cosmetic, the foundation must strictly adhere to domestic and international standards, with high-end products requiring even greater batch consistency. The CHNSpec SPF series analyzers fully support authoritative standards such as the “Cosmetic Safety Technical Specifications,” ISO23675, ISO23698, and FDA 2019. The testing data can be directly used as in vitro test reports, saving time and costs in the product launch compliance process. With a wavelength accuracy of ±0.1nm and spectral resolution of less than 2nm, the analyzer ensures high reproducibility of test data, accurately controlling the variation in sun protection efficacy across different batches of sunscreen foundation from R&D to mass production, ensuring stable product quality throughout the entire process. From the formulation research and full-spectrum protection validation of high-end sunscreen foundations to compliance testing and mass production quality control, the CHNSpec SPF Sun Protection Factor Analyzer addresses core issues such as powder interference, film-forming impact, and full-spectrum testing in sunscreen foundation analysis. It helps companies develop high-quality products with both “premium cosmetic experience” and “precise, long-lasting sun protection,” creating a competitive edge in the high-end sunscreen market.
