Preventing Settling of Fluorescent Yellow Pigment (Need for Suspending Agent)

Yes, the Fluorescent Yellow Pigment is a pigment powder that is not soluble and cannot dissolve in the formula. It is designed to be dispersed (spread) in the product.

Because it is a non-dissolving powder, it will naturally settle or precipitate (sediment) over time.

To prevent settling and keep the pigment evenly distributed, you must use a suitable suspending agent (e.g., thickeners or gums like Xanthan Gum, Carbomer, or specific suspending polymers) in your formulation.
