Hydrolyzed Oat Protein

Hydrolyzed oat protein (or hydrolyzed oats; the names seem to be used interchangeably) is a liquid cosmetic ingredient made from oat protein that has been modified to be water-soluble.

It boosts the moisturizing & hydrating properties of our formulations while improving skin feel. I love it in skincare and haircare products!

Hydrolyzed oat protein helps boost the moisturizing properties of our products by helping hold water to the skin.

No, but it is a good starter hydrolyzed protein.

Excellent moisture retention with improved skin feel.

Those with severe wheat allergies may wish to avoid hydrolyzed oat protein due to possible cross-contamination concerns.

A different hydrolyzed protein would be the best substitution for hydrolyzed oat protein. Try hydrolyzed silk, baobab, quinoa, rice, or wheat proteins.

Include it in the water phase of your recipe; it can be hot or cold processed. If I can put it in the cool-down phase of a formulation, I will.

Stored somewhere cool, dark, and dry, hydrolyzed oat protein should last 12–18 months.

Hydrolyzed oat protein will typically contain preservatives as it is an aqueous product; check the spec sheets from your suppliers to find out what preservative is in the one your purchase if that matters to you.

I love to combine hydrolyzed oat protein with colloidal oatmeal and oat oil for lovely oat-themed formulations!
