Water Resistance of Sunscreen Assessment
The water resistance assessment of sunscreens is a critical component in ensuring that cosmetic products meet regulatory requirements and consumer expectations. This service focuses on evaluating how well sunscreen formulations maintain their protective properties when exposed to water, which can significantly reduce the effectiveness of sunscreen if not adequately tested.
Understanding the importance of this test involves recognizing that water resistance is measured based on the time it takes for a specific amount of water (typically 20 ml) to wash off the sunscreen from an applied layer on human skin. This test is particularly important because many users, especially those engaging in aquatic activities, may unknowingly reduce their sun protection by washing away the sunscreen.
The ISO standard relevant to this assessment is ISO 18437:2018, which provides detailed guidance for testing water resistance of cosmetic sunscreens. This international standard ensures that all tests are conducted under consistent and reproducible conditions, enhancing reliability across different laboratories around the world.
During the test, a layer of sunscreen is applied to the skin in accordance with specified guidelines, followed by exposing it to a standardized amount of water for a set duration. The effectiveness of the sunscreen after this exposure period is then evaluated based on its UV protection factor (SPF). If the SPF drops below the claimed value by more than 40% or if the SPF becomes zero, the sunscreen fails the test and does not meet regulatory requirements.
This assessment service includes comprehensive analysis using state-of-the-art equipment that simulates real-world conditions as closely as possible. Our technicians follow stringent protocols to ensure accurate and reliable results. By partnering with us for this crucial step in product development or compliance assurance, your company can rest assured that its sunscreen products are robustly tested and ready for the market.
Understanding the broader context of regulatory compliance is important. Regulatory bodies like the European Commission (EC) and the US Food and Drug Administration (FDA) have stringent requirements for water resistance testing to ensure consumer safety. By adhering to these standards, manufacturers can avoid potential legal issues and maintain a strong reputation in the industry.
