Incompatibility and Texture Issues in Facial Gel Formulation with Double Hyaluron Liquid and Glycerin Gel

Hello, thank you for reaching out.

Regarding the issue with your facial gel formulation, the staff has reviewed your formula and the problem you encountered (pink membranes/lumps and failure to gel).

Based on their initial assessment, the staff suspects that there might be an incompatibility between Double Hyaluron Liquid and Glycerin Gel. This incompatibility is likely the cause of the precipitation (forming the pink membranes/lumps) and the failure of the mixture to form a stable gel structure.

You are correct in your suspicion about the mixing order. While the suspected incompatibility is a major factor, generally, gelling agents like Glycerin Gel should be dispersed and allowed to hydrate first to form the gel base before incorporating other ingredients. Adding it last to a solution containing other active ingredients, especially potentially incompatible ones, can prevent proper gel formation and lead to issues like precipitation.

Regarding your question about using the failed batch as a toner: Due to the visible signs of incompatibility and separation (the pink membranes/lumps), it is not recommended to use this mixture on your skin. The precipitated material may not be safe or effective, and applying an unstable formulation could potentially cause skin irritation or other adverse reactions. It is best to discard this batch.

The staff is currently performing tests to confirm the incompatibility between Double Hyaluron Liquid and Glycerin Gel. Once confirmed, this information will be added as a warning on the respective product pages to benefit other members.

We appreciate your understanding and patience while the staff completes their investigation.
