Clariant has launch the SENSEACTION line of color masterbatches intended for use in the production of caps and closures used on bottled water packaging. SENSEACTION masterbatches, which are available in a wide range of colors, are specially formulated, processed, tested, and certified to be free of detectable negative organoleptic (taste and odor) effects.
The new line was developed to meet the high demands of bottled water producers and the processors who supply them with caps and closures, which are typically made of HDPE or polypropylene. Although processors have always utilized safe, food-grade pigments to color caps and closures, there is the potential that pigments in them could contain trace elements that, even in minute quantities, could impart a detectable taste or odor to bottled water or beverages.
SENSEACTION color masterbatches start with raw materials that are food-contact compliant, including pigments and carrier resins that are carefully selected for use in sensitive organoleptic applications. Manufacturing takes place exclusively using dedicated processes and special equipment at a dedicated masterbatch site. When manufacturing is complete, each lot of SENSEACTION masterbatch undergoes an exposure in water, which then is tested according to DIN 10995 at an independent external laboratory. A panel of professional testers, specially selected for their acute sense of taste and smell, evaluate the samples for adverse organoleptic effects.
