Old-fashioned oats are whole rolled oats — the same oats found in a bowl of oatmeal — used in soap making as a surface garnish rather than a formulation ingredient. They appear pressed into the top of bars that contain colloidal oats in the formula itself, serving as a visual cue and a tactile element that connects the finished bar to its ingredients.
Unlike colloidal oats, which are finely milled into a powder and worked into the soap batter to contribute skin-soothing properties throughout the bar, old-fashioned oats are applied to the surface only. They don’t dissolve into the lather or deliver significant skin benefits on their own — their role is decorative and communicative. When you see whole oats on top of a bar, it signals what’s inside.
The texture of rolled oats on the surface of a bar can also add a very mild exfoliating quality on the first few uses, before they soften and wash away with use. It’s a gentle effect — nothing like pumice or walnut hull — but a noticeable one.
Here are a few of our products that use this ingredient as a garnish:
