Our take
Is Quaternium-90 Sepiolite a Good Ingredient?
Good, because it reinforces oil-gel networks and curbs excess slip and shine with consistent, stable performance and low general irritation. It isn't rated Great since its benefits are mainly aesthetic and structural, and the cationic treatment may occasionally irritate very reactive skin.
What it does
Skin Benefits
Builds a supportive network that feels smooth yet controlled during application, and helps curb excess glossiness in oil-rich formats.
