Dry-Flo [Aluminum Starch Octenylsuccinate] is a hydrophobically modified natural polymer, which imparts a smooth, velvety feel in a variety of topical personal care and cosmetic products such as powders and makeup. When used in lotions, creams and under arm products, Dry-flo AF mitigates the unpleasant, heavy, oily feel of the oils and waxes often used in these formulations.
If you've been having trouble with your body powders clumping, then this is the product for you. Use it 1:1 with your Arrowroot (or rice flour) to make a wonderfully luxurious body powder.
