Our take
Is Castoryl Maleate a Good Ingredient?
It's an effective, stable emollient that improves softness and helps reduce moisture loss with generally low irritation risk, which earns it a Good rating; while not a treatment active, it reliably improves skin feel and barrier comfort in many formulas.
What it does
Skin Benefits
Softens rough patches and helps reduce tightness by improving the skin's surface lipids, and supports moisture retention for a smoother, more supple feel.
Where you'll find it
Uses in Skincare & Cosmetics
Used in rich creams, balms, and barrier-focused moisturizers, as well as lip treatments and hand creams targeting dryness.
Before you use it
Safety
Usually well tolerated with a low chance of irritation. Those with very sensitive skin should patch test, as individual responses to emollient esters can vary.
