Addressing Precipitation in Your Formula

Your formula, containing high amounts of solid ingredients like Menthol, Borneol, and Camphor, is likely experiencing precipitation because these solids are not fully dissolving or remaining stable in the liquid phase (Eucalyptus Oil).

To resolve this, you can add a suitable solvent or solubilizer. As suggested, LipidSoft™ Deo (Triethyl Citrate) is an effective option. It can help dissolve the solid components and improve the overall stability of the mixture, preventing the ingredients from separating and precipitating over time.

Recommendation:

Add LipidSoft™ Deo to your formula at a rate at least equal to the total weight of your powdered ingredients (Menthol, Borneol, and Camphor). In your case, the total weight of powdered ingredients is 400g + 200g + 200g = 800g. Therefore, you should add at least 800g of LipidSoft™ Deo to help dissolve the solids and prevent precipitation.
