In the detergent, cosmetic, and hygiene industries, visual consistency and product stability are essential for consumer satisfaction and brand integrity. Portable and desktop spectrophotometers from BYK-Gardner are used to measure color hue across various scales and calculate color differences (ΔE*), as well as quantify yellowness, whiteness, and stain fading. These instruments enable precise color control for liquids, creams, and packaging materials. To complement instrumental analysis, color comparison booths equipped with standardized illuminants such as D65, D50, TL84, A, and UV allow visual inspection under real-world lighting conditions, ensuring consistent appearance across production batches.
Environmental resistance testing is equally vital, especially for products exposed to light, heat, and humidity during storage and use. BYK-Gardner’s UV condition booths with UVA and UVB lamps, along with Xenon test chambers featuring variable wavelength filters, simulate accelerated aging and environmental stress. These tests are designed to meet international standards and deliver rapid, reproducible results. For packaging and product surfaces, BYK also offers specialized sample holders and gloss meters that accommodate curved and reflective shapes, such as shampoo bottles or cosmetic jars, ensuring repeatable and accurate measurements. This combination of high-precision instrumentation and standardized testing protocols supports robust quality control and predictive modeling in product development and manufacturing.
