Colloidal Oatmeal

Colloidal Oatmeal (Avena sativa)

Colloidal oatmeal is a finely milled oat preparation valued for its soothing, moisturizing, and protective qualities. When dispersed in water, it forms a soft suspension that helps calm irritated skin and support moisture balance.

In apothecary work, colloidal oatmeal is commonly used in soothing baths, skin treatments, and gentle cleansing preparations.
