Description
The Color Retention Efficacy Claim Test is a clinical evaluation designed to assess a product’s ability to maintain its original color intensity and vibrancy over time. This test is commonly applied to hair dyes, lipsticks, foundations, and color cosmetics. It involves monitoring the product’s appearance under real-use conditions, such as exposure to light, water, sweat, and friction, over a specific period. Conducted under expert supervision using visual grading and instrumental color analysis, the test helps validate claims like “long-lasting color” or “fade-resistant finish.” It provides scientific support for product claims and enhances consumer confidence through proven performance.
