Bright Dyes FLT
Blue products are specially formulated versions of
food grade dye FD & C Blue. Bright Dyes FLT
Blue products have been certified by NSF
International to the ANSI/NSF Standard 60 for use
in drinking water. This dye is used for visual
detection only and cannot be seen under ultraviolet
light or detected by fluorometry. However, when
used visually, its color is often thought to be
more acceptable to public view than the fluorescing
red or yellow green Bright Dyes products. In this
respect, it is sometimes used in fountains, ponds
and streams for decorative effect. Visually, the
dye appears as aqua to royal blue depending on its
concentration and activity of the water.
Based on
biochemical oxygen demand (BOD) studies, the dye is
biodegradable with 77% of the available oxygen
consumed in 7 days. As always the suitability of
these products for any specific application should
be evaluated by a qualified hydrologist or other
industry professional.
