🌾 What Are Colloidal Oats?
Colloidal oats (often called colloidal oatmeal) are oats that have been finely ground into a silky powder that can disperse evenly in water and skincare products.
Unlike regular oatmeal, colloidal oats are processed specifically for skincare use, allowing them to:
- suspend in products more evenly
- feel smoother on skin
- create a soothing, protective barrier
They are commonly used in:
- eczema products
- sensitive skin formulas
- bath soaks
- lotions and creams
- facial skincare
🥛 What Is Oat Milk in Skincare?
Oat milk is created by soaking and blending oats with water, then straining the liquid.
In skincare and soap making, oat milk adds:
- creaminess
- soothing properties
- gentle hydration
- luxurious texture
It’s especially popular in:
- cold process soap
- bath products
- creamy body care formulas
✨ Why Oats Are So Good for Skin
1. Soothes Dry & Irritated Skin
Oats are famous for their calming properties.
They help reduce the appearance of:
- dryness
- itchiness
- redness
- irritation
This is why oat-based products are commonly recommended for sensitive skin.
2. Supports the Skin Barrier
Colloidal oats contain compounds that help form a protective barrier over the skin, helping reduce moisture loss and support healthier-looking skin.
👉 Especially helpful for:
- damaged skin barriers
- dry climates
- over-exfoliated skin
3. Gentle Cleansing Properties
Oats naturally contain mild cleansing compounds called saponins, which help gently cleanse the skin without stripping moisture.
This makes oats perfect for:
- facial products
- baby products
- gentle soaps
4. Adds Creaminess & Slip
In formulations, oats help products feel:
- smoother
- creamier
- more luxurious
This is especially noticeable in:
- soap lather
- body butters
- bath soaks
5. Ideal for Sensitive Skin
Oat ingredients are often used in products designed for:
- sensitive skin
- mature skin
- dry skin
- eczema-prone skin
Their gentle nature makes them one of the safest ingredients for calming skincare formulations.

🧼 Using Oats in Soap Making
Oat Milk Soap🥛 Oat Milk in Soap
Oat milk creates:
- creamier lather
- silkier texture
- soothing skin feel
Important Tip:
Because oat milk contains natural sugars, soap batter can heat up faster.
👉 Many soap makers freeze oat milk before mixing with lye to help prevent scorching.
I use a 50% lye solution (equal parts lye/water) and like to add my oat milk directly to my oils before adding my lye solution to the oils. This is how I make all of my milk soaps.
