2,4-Diaminophenoxyethanol HCl

High risk

FunctionDye intermediate

What it is — 2,4-Diaminophenoxyethanol HCl (INCI of the same name), a synthetic oxidative hair-dye intermediate, or dye precursor.

What it does — It is used in permanent and oxidative hair color, where it reacts during the coloring process to help develop and build the final shade.

Typical use — Found in permanent hair-dye systems, typically combined with a developer and other dye precursors rather than in leave-on skincare.

Who it suits / good to know — Intended for hair-coloring formulas; it is not a skin-care active and permitted levels are regulated.

Safety — Rated high risk here as an oxidative dye intermediate and a potential skin sensitizer. This is general information, not medical advice; always follow the product's directions and complete the manufacturer's patch (allergy alert) test before each use.

Why we grade it High: High risk — oxidative hair-dye intermediate; potential sensitizer, patch-test before use.
