How to Dissolve Clover Flower Extract and Silymarin

Clover Flower Extract 0.5%

Regarding the 0.5% Clover Flower Extract, based on your description that it dissolves with heat but precipitates upon cooling in water, this indicates that some components in the extract have limited solubility in water at lower temperatures. If you need it to remain dissolved in a water-based formula, you might consider using a co-solvent such as Propylene Glycol or Butylene Glycol in combination with water, or potentially a dispersant to help keep components suspended if complete dissolution isn't achievable at room temperature. The appropriate amount of co-solvent or dispersant would depend on the specific extract you are using and would require testing.

Silymarin 1%

For the 1% Silymarin that you are trying to dissolve in oil without success, based on our product information (Silybum Marianum Fruit Extract), which contains Silymarin as a main component, it is specified as water-soluble and the mixing method is to mix it in water, avoiding heat. This is why you are having difficulty dissolving it well in oil, even with Ultra Solve. The correct way to dissolve this type of Silymarin is to mix it into the water phase of your formulation, without using heat. The recommended usage rate is 0.1-1.0% (0.3% recommended).
