The cosmetic and personal care industry use crushed walnut shell media as an exfoliate in facial, body, and foot scrubs. A crushed walnut shell is a hard, fibrous material ideal as an abrasive material. Crushed walnut shell grit is extremely durable, angular & multi-faceted, yet considered a soft abrasive. Walnut shell powder is prepared by controlled grinding of the shells of walnuts into excellent particle sizes, acting as a soft abrasive in cosmetics products, skincare, exfoliation, creams, bar soaps, exfoliating products, shower gel, and cleansing products.
More aggressive formulations will use particle sizes as large as 20-40 mesh. The walnut shell’s soft abrasive nature is still viable in flour sizes at 200 mesh and smaller for sensitive, fine scrubs.
