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.

TiO2 is not water soluble, so it won’t help. Instead, you could use something like benzophenone-4. Also, add some chelant just to be safe. But again, if the issue comes from an stability in your formula, then that’s a different story. You should check at the rate of color change.

In my opinion, when I use natural colors, when exposed to UV rays, it stimulates the energy of the molecules, leading to the breaking of double bonds, causing color change. So do you think there is a way to solve it from the solution itself?

It’s normal for chromophores to absorb radiation and have a change in color. If that’s your situation, then a water soluble UV filter is needed. But again, there are different reasons to color change, so chek properly which one that is.

Color loss in your herbal shower gel could result from photolysis or oxidation. Protect your formula by adding UV absorbers, antioxidants, or adjusting the pH for better dye stability.
