Caution
Dry Flow PC is a hydrophobically modified corn starch that is used for imparting a soft, silky feel to products and also works as an oil adsorbent. It is a free-flowing, anti-caking ingredient that has a fine and uniform particle size, and is easy to use. It improves aesthetics and reduces the greasiness produced by oils and occlusive agents in lotions, creams, and ointments while also improving the flow properties of powders.
It leaves a matte finish on the skin and is used to enhance SPF solutions so that it doesn't leave an undesirable white film on the skin. Dry Flow PC is fat-soluble and slightly acidifying.
