Tartrazine Powder CI 19140 synthetic water soluble colorant for formulation systems and industrial applications
Tartrazine Powder CI 19140 is a synthetic azo dye supplied in dry form for controlled and reproducible yellow coloration in a wide range of formulation systems. The powder format provides extended shelf stability ease of storage and precise dosing in both laboratory and industrial environments. It is used in food processing cosmetic formulations nutraceutical and pharmaceutical products as well as in household and industrial systems where a reliable water soluble colorant is required.
From a technical perspective Tartrazine exhibits high tinctorial strength allowing effective coloration at very low inclusion levels. It dissolves rapidly in water forming clear homogeneous solutions without residue. The molecule maintains stability across a broad pH range and demonstrates compatibility with multiple formulation bases including aqueous systems surfactant solutions polymer gels and emulsions. This makes it a versatile component for modern formulation design.
In food related applications Tartrazine Powder is used in beverages confectionery dry mixes desserts and sauces to achieve consistent yellow coloration. In cosmetic systems it is incorporated into shampoos liquid soaps gels and decorative formulations for visual differentiation. In pharmaceutical and nutraceutical products it is used to color tablets capsules syrups and liquid concentrates. In household products it is applied in detergents cleaners and gel based systems. In industrial formulations it is used wherever stable synthetic colorants are required.
Functionally Tartrazine acts solely as a colorant and does not contribute to viscosity structure or rheology of the system. When properly dissolved it distributes evenly providing uniform visual appearance. Its high color intensity allows minimal usage while maintaining desired shade consistency.
In formulation practice the powder is pre dissolved in water before addition to the main system. It is compatible with polyols surfactants hydrocolloids preservation systems and various active components. Complete dissolution and uniform mixing are essential for consistent color distribution.
Usage levels depend on the target shade and formulation type and are defined by the formulator.
