Solving the problem of color loss in products
<font style=”vertical-align: inherit;”><font style=”vertical-align: inherit;”>in my herbal shower gel formula there is a dye used, whether I tried natural or synthetic dyes it still loses color when exposed to natural light. I am having a headache wondering if it is photolysis or oxidation or is there any other reason? I really hope to get help?</font></font>

If it happens right away, then UV is not to blame; but if it happens gradually or only in a UV chamber and your package is transparent, then you need a UV filter.
