Skin Benefits

Uses In Skincare & Cosmetics

It's used in gel face washes, milky cleansers, and lightweight lotions where stable oil-in-water textures are desired, and appears in sprayable emulsions and makeup-removing cleansers.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

It carries generally low irritation, but very sensitive users may experience dryness or mild sting with frequent use. Avoid direct eye contact and rinse thoroughly.

Is Sodium Lauroyl Aspartate a Good Ingredient?

It rates Good because it provides gentle, amino acid-based cleansing and helps stabilize light emulsions, with typically low irritation versus sulfates. It may be less foamy and less heavy-duty than stronger anionics, so it's best for mild or daily cleansers rather than a top-tier all-purpose surfactant.
