Why This Standard is Important

Sun protection is a critical aspect of skincare, and the SPF value is a key indicator of a product's ability to protect the skin from harmful UV rays. The BS EN ISO 23675:2025 standard outlines precise test methods that ensure the accuracy and reliability of SPF measurements. By adhering to these methods, manufacturers can provide consumers with products that offer genuine protection against sun damage.

Moreover, this standard helps harmonize testing procedures across the industry, facilitating international trade and ensuring that products meet global safety standards. This is particularly important for companies looking to expand their market reach and establish trust with consumers worldwide.

Detailed Methodologies

The BS EN ISO 23675:2025 standard includes a range of in vitro test methods designed to accurately determine the SPF of cosmetic products. These methods are based on scientific research and have been developed to provide consistent and reproducible results. The standard covers various aspects of testing, including:

• Preparation of test samples
• Selection of appropriate substrates
• Application techniques for test products
• Measurement of UV transmittance
• Calculation of SPF values

Each step is meticulously detailed to ensure that all tests are conducted under standardized conditions, minimizing variability and enhancing the reliability of results.

Benefits for Manufacturers and Consumers

For manufacturers, adhering to the BS EN ISO 23675:2025 standard means that their products are tested using the most up-to-date and scientifically validated methods. This not only helps in meeting regulatory requirements but also enhances the credibility of their products in the eyes of consumers.

Consumers, on the other hand, benefit from the assurance that products labeled with SPF values have been rigorously tested and meet high safety standards. This is particularly important for individuals with sensitive skin or those who are at higher risk of sun damage.

Conclusion

The BS EN ISO 23675:2025 standard is an indispensable resource for anyone involved in the development, testing, and marketing of sun protection products. By providing a clear and detailed framework for SPF testing, it ensures that products are both safe and effective, offering consumers the protection they need against the harmful effects of the sun.

Whether you are a manufacturer looking to enhance your product line or a consumer seeking reliable sun protection, the BS EN ISO 23675:2025 standard is your guide to understanding and achieving the highest standards in sun protection.

• 71.100.70 Cosmetics. Toiletries

This document specifies a method for the in vitro determination of sun protection factor (SPF). This method is applicable to sunscreen products in form of an emulsion or alcoholic one-phase formulation, excluding in form of a loose or compressed powder or stick. Specifications are given to enable determination of the spectral absorbance characteristics of SPF protection in a reproducible manner. Use of this method is strictly for the determination of a static sun protection factor. It is not applicable for the determination of water-resistance properties of a sun protection product.
