Technical Advantages
Light Stability
Retail shelves, clear packaging and long distribution chains expose products to light. Our colorants are formulated to stay vivid until the last day of shelf life.
Light, especially UV, breaks down conjugated double bonds that give pigments their color. We use natural antioxidants like rosemary extract and ascorbic acid, and recommend UV-blocking packaging where needed.
Light stability is rated excellent, good or moderate based on ΔE after accelerated xenon-arc exposure equivalent to several months of retail display.
Test Method
Xenon-arc chamber, 72 h, 550 W/m², samples in clear PET; ΔE < 3 excellent, 3–6 good, > 6 moderate.
