Microbial contamination in gel formulation

Question

I made a gel formulation with Chamomile Water 94%, Xanthan Gum 1%, and Glycerine 5%. After 10 days, a thin white film appeared in the gel. What could be the cause of this?

MySkinRecipes Expert · Accepted Answer

The thin white film observed in your gel after 10 days is likely due to microbial contamination, such as bacteria or mold.

Your formulation contains a very high percentage of water (94% Chamomile Water) and does not include a preservative. Water-based products without adequate preservation are highly susceptible to microbial growth, especially over time.

To prevent this issue in the future, you should add a suitable broad-spectrum preservative to your formulation.

We recommend discarding the current batch as it is contaminated.
