Oat Milk
Appears in 2 scanned products.
A liquid made by soaking and blending oats, used in some handmade soaps and skincare in place of or alongside water. It is not a standardized INCI-registered ingredient, so its exact composition varies by maker.
Why it’s used
Small-batch formulators add it for its mild, soothing reputation and to give handmade bars a creamy appearance and gentle marketing story.
What the evidence says
There is little formal safety or efficacy literature specifically on oat milk in cosmetic formulation, as opposed to oat extracts or colloidal oatmeal, which are better studied. The evidence here is limited.
