How Amber Bottles Work
The amber color in our polypropylene bottles comes from iron oxide pigments that absorb UV and short-wavelength visible light (below 450nm). This is the range where most photodegradation of pharmaceutical compounds occurs.
Current wavelength (500nm): This is in the visible light range. While some light passes through (allowing you to see the contents), the amber color still provides protection against the most harmful wavelengths below 450nm.
