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.

A scientific research achievement that has made significant progress in the field of rapid detection of wound infection bacteria has been officially published. The study was jointly completed by Chongqing University of Posts and Telecommunications, Daping Hospital of the Army Medical University, and other institutions. By combining fluorescence hyperspectral imaging technology with deep learning algorithms, the research achieved non-invasive, rapid classification and identification of multiple common wound pathogens. During the data acquisition stage, the research team used the FigSpec FS-22 hyperspectral imaging camera from CHNSpec, which provided critical spectral image data support for the experiments and demonstrated the device’s application potential in precision bio-optical detection. Timely diagnosis of wound bacterial infections is of great importance for clinical treatment. However, traditional methods such as bacterial culture and PCR are often time-consuming and require invasive sampling. Therefore, developing a technology capable of rapidly and non-invasively identifying bacteria has become an urgent need. Hyperspectral imaging technology can simultaneously obtain spatial information and continuous spectral information of a target, while fluorescence hyperspectral imaging goes a step further by inducing the sample to emit fluorescence through excitation at specific wavelengths, thereby enhancing the ability to detect differences in internal chemical substances of microorganisms. This study leveraged this principle to systematically collect and analyze the spectral characteristics of eight common wound infection bacteria. In the experiments, the CHNSpec FigSpec FS-22 hyperspectral camera played a crucial role. The system features a spectral detection range of 400–1000 nm and a high spatial resolution of 1920 × 1920, enabling it to finely capture the autofluorescence signals generated by bacteria under 405 nm laser excitation. The research team constructed a large fluorescence hyperspectral dataset covering different bacterial species, concentrations, and growth times, totaling 25,600 samples. Faced with the challenges of high dimensionality, large information volume, and subtle spectral differences among bacteria in hyperspectral data, the researchers independently designed a deep learning model called the “Spatial–Spectral Multi-Scale Attention Network.” This model can effectively focus on bacterial colony regions, suppress background interference such as culture substrates, and deeply extract discriminative features from the spectral dimension, thereby enabling collaborative identification of bacterial species, growth states, and even concentrations. The research results show that this method achieved a bacterial classification accuracy of 98.52% under different growth conditions, a species-level identification accuracy of 98.71%, and maintained effective detection even at bacterial concentrations as low as 10⁴ CFU/mL. Compared with multiple existing algorithm models evaluated in the study, this network trained on hyperspectral data from CHNSpec demonstrated reliable performance. These results verify the feasibility of combining fluorescence hyperspectral imaging with advanced algorithms in the field of rapid microorganism detection and provide important technical references for the future development of instant diagnostic devices applicable to clinical environments. Although the study was conducted under controlled laboratory conditions using purified bacterial strains, its technical pathway clearly demonstrates the value of hyperspectral imaging in biomedical detection.

In the current white-hot competition of the sunscreen track in the beauty industry, product R&D efficiency, cost control, and compliance have become the core keys for enterprises to seize market opportunities. The CHNSpec SPF-660 series Cosmetics Sun Protection Factor Analyzer, as the core tool for in vitro testing of cosmetics sunscreen designated by regulations, accurately addresses the pain points of the entire sunscreen R&D process. With the three core values of cost saving, compliance, and efficiency enhancement, it creates a full-link efficient solution for enterprises from formula R&D to product launch, becoming an "essential weapon" in the sunscreen R&D process. Precision cost control ensures not a single cent of R&D investment is wasted. In traditional sunscreen product R&D, human testing is not only expensive but also carries the risk of testing failure due to non-standard formulas, which easily leads to a double loss of capital and time. The CHNSpec SPF-660 series allows enterprises to complete independent preliminary testing before sending products out for human testing. Through precise in vitro testing data, qualified formulas can be screened out to ensure subsequent human testing hits the mark on the first try. This avoids invalid testing costs from the source and allows R&D funds to be precisely invested in effective formula optimization, achieving refined management and control of R&D costs. Compliance as the foundation ensures a worry-free product launch process. As supervision in the cosmetics industry becomes increasingly strict, testing standards and compliance requirements for sunscreen products continue to rise, making in vitro testing a necessary step for product R&D and launch. The CHNSpec SPF-660 series fully aligns with domestic and international mainstream testing standards. It not only strictly follows the "Safety and Technical Standards for Cosmetics" but also adapts to international cosmetics sunscreen testing standards such as ISO 23675, ISO 23698, and ISO 24443. At the same time, it complies with FDA 2012 & 2019 sunscreen product labeling and efficacy testing specifications, COLIPA (2011) in vitro UVA protection factor determination standards, and Boots Star Rating (2011) UVA protection labeling standards. It safeguards product compliance from the early stages of R&D, avoiding issues such as market entry barriers or compliance rectification caused by non-conforming standards, and ensures that the entire process of sunscreen product R&D, testing, and launch aligns with regulatory requirements. Efficient R&D keeps new product launches one step ahead. In traditional sunscreen formula R&D, one must wait for a third-party testing agency to issue a report after modifying a formula, which takes several days at least and several weeks at most. This significantly stretches the R&D cycle and makes it easy to miss market windows. The CHNSpec SPF-660 series achieves immediate data output upon formula modification, with a single scan taking only about 1 second. R&D personnel can complete all-dimensional testing right in the laboratory without the time-consuming wait for third-party reports, greatly shortening the cycle of formula adjustment, verification, and optimization. From formula preliminary screening to final finalization, the efficiency of the entire R&D process increases geometrically, allowing enterprises' new sunscreen products to be pushed to market faster, easily widening the time gap with competitors and seizing market dividends. From cost control in formula R&D to compliance assurance in the testing process, and then to the efficiency improvement of new product launches, the CHNSpec SPF-660 series reconstructs the sunscreen cosmetics R&D process with its "trinity" core advantages. It provides professional, efficient, and compliant in vitro testing solutions for beauty enterprises and R&D institutions, assisting companies in continuously creating blockbuster sunscreen products in the fierce market competition.
