How to Dissolve Propolis Extract (High Flavonoids) Completely

You are experiencing incomplete dissolution of Propolis Extract (Liquid, Water-Soluble, High Flavonoids) even when using Propylene Glycol. Based on the product information, this specific propolis extract is described as water-soluble.

The recommended method for mixing this Propolis Extract is to mix it in the water phase of your formulation. It is also advised not to expose it to heat.

While Propylene Glycol and Butylene Glycol can act as solvents and are soluble in water, the primary solvent for this extract is water itself. Using only 5% Propylene Glycol might not be sufficient to fully dissolve the extract, especially if it's not incorporated into the main water phase.

To ensure complete dissolution and avoid sediment, try the following:

1. Prepare your water phase according to your formula.
2. Add the required amount of Propolis Extract (Liquid, Water-Soluble, High Flavonoids) directly into the water phase.
3. Stir gently until fully dissolved. Avoid heating the mixture.
4. Proceed with adding other ingredients to your formulation as usual.

If you still experience issues with dissolution, you could try pre-dissolving the Propolis Extract in a small amount of the water phase first before adding it to the bulk of the water phase. You can also use Propylene Glycol or Butylene Glycol in combination with water in the water phase to aid dissolution, ensuring the total concentration of the glycol is within the recommended usage rate (typically 1-20%). However, the key is to utilize the water solubility of the extract by mixing it into the water phase.

Remember to store the Propolis Extract in the refrigerator as recommended.
