What is the relationship between Liquid Brilliant Blue FCF and powdered Acid Blue 9?
Liquid Brilliant Blue FCF is the pre-dissolved aqueous solution of Acid Blue 9 (Brilliant Blue FCF, CAS 2650-18-2), with an identical active ingredient; the difference is the form - the liquid needs no dissolution and can be metered directly, while the powder is convenient for storage and stock-keeping, and suitability for automated feeding should be assessed against your line. Choose the form by how your line is fed.
What are the color value and key specifications?
Dark blue liquid with a color value (E1% 1cm, 628nm) of ≥0.20, pH 5.0–7.0, insoluble matter ≤0.2%, arsenic ≤1 mg/kg and heavy metals (as Pb) ≤20 mg/kg (see specifications). Production and release inspection follow the specifications on this page; batch data is confirmed with our sales team during inquiry.
Why choose the liquid form?
The liquid needs no dissolution step, reducing on-site dissolving equipment and handling time; suitability for automated feeding should be assessed against your line configuration, and processing steps that require a dry powder form do not apply to this product. Assess the choice against your own process.
What should be checked before use and dosing?
Before use, the drummed liquid can be checked visually for homogeneity and sampled after mixing; the color value (E1% 1cm, 628nm) and pH (see specifications) are checked batch by batch, with batch data confirmed by our sales team during inquiry. Dosing is arranged according to the metering method of your line, and fit is assessed on the line itself.
What packaging and order quantities are available?
Standard packaging is a 1000 kg drum, and custom packaging is available; in volume production, withdrawal can be arranged around the metering method of your line. Sample arrangements and order quantities can be discussed during inquiry; regular batches are produced against the order schedule.
What are the storage and transport requirements?
Store sealed in a cool, dry, well-ventilated place, protected from light and heat; as a water-based liquid, the product needs protection from freezing in low-temperature environments, and after prolonged storage it is advisable to mix and check before use. Transport classification follows the goods transport appraisal report and the carrier's requirements, with packaging kept intact.
