Sodium Hydroxide

Low risk

FunctionpH Adjuster

What it is — Sodium Hydroxide (INCI: Sodium Hydroxide), also known as lye, is a strong alkali used in tiny amounts to adjust a formula's pH.

What it does — It is commonly used to neutralize acids and bring a product to its intended, skin-appropriate pH.

Typical use — It appears at trace levels across many products and helps set the pH of gels, cleansers and acid-containing formulas.

Who it suits / good to know — Although concentrated sodium hydroxide is caustic, in finished products it is used at trace levels and neutralized, so the final formula is balanced. It shapes pH rather than acting as a skincare ingredient.

Safety — DHALIORA grades it low risk: a pH adjuster neutralized to trace levels in finished formulas. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk — a pH adjuster neutralized to trace levels in finished formulas.
