The Colour Retention Claim Test for color cosmetics assesses a product’s ability to maintain its original shade, vibrancy, and intensity over time. This test is critical for substantiating claims such as “fade-proof,” “long-wear color,” or “color stays true,” especially for lipsticks, eyeshadows, blushes, and foundations.

Under controlled environmental conditions, the product is applied and monitored at defined intervals to evaluate changes in color due to wear, exposure to light, humidity, or skin interaction. Both instrumental colorimetric analysis and expert visual grading are used to ensure accurate and reproducible results.

This test provides scientific validation of color longevity, supports regulatory compliance, and enhances brand credibility by proving that your product retains its visual appeal throughout the day.
