Q1: What is the primary application field for Sanolin Tartrazine X 90?
A: Sanolin Tartrazine X 90 is a high-performance, water-soluble yellow pigment specifically developed for use in aqueous-based industrial inkjet inks, particularly for textile digital printing on natural fibers such as cotton and viscose.
Q2: Is this pigment suitable for food-contact applications?
A: No — Sanolin Tartrazine X 90 is not approved for direct food-contact applications. It is formulated for industrial and decorative uses only, and its regulatory status does not cover migration-sensitive substrates such as packaging or food containers.
Q3: How stable is this pigment under typical inkjet printing conditions?
A: Sanolin Tartrazine X 90 exhibits excellent thermal and shear stability in standard aqueous inkjet formulations, supporting reliable jetting performance across common piezoelectric print heads without significant nozzle clogging or precipitation over extended run times.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of moisture. Avoid freezing, and ensure good ventilation during handling to minimize dust exposure in dry form.
