Colloidal oatmeal’s scientific qualities are due to its many natural chemicals. Saponins (a form of natural detergent) comprise its cleaning ability. It also has a high level of starch and beta-glucan (a polysaccharide with inhibiting abilities), which is primarily responsible for its moisture-retentive properties. Colloidal oatmeal also contains phenols (a form of antiseptic), which encompass its anti-inflammatory, antioxidant and ultraviolet absorbing properties. It can also be used as a gentle exfoliating agent. These healing qualities can all be transmitted to skin via soap.
