Colloidal Oatmeal USP

Description Colloidal oatmeal is finely milled whole oat kernel ( Avena sativa ), processed into a fine powder that disperses easily in water and oil-based formulations. USP grade means it meets pharmacopeial standards for purity and particle size — important for consistent performance in skin-contact products. Oat kernel contains naturally occurring beta-glucans, lipids, and phenolic compounds (including avenanthramides), which is why colloidal oatmeal has long been used in bath and skincare products to help soothe and soften the skin. It's recognised by the FDA as a skin protectant ingredient for use in over-the-counter products, making it a well-documented choice for formulators working on gentle, everyday skincare.
