2-METHYLRESORCINOL

2-METHYLRESORCINOL is a small organic molecule in the resorcinol family. It has two hydroxyl groups attached to an aromatic ring and one methyl group; that detail accounts for the "2-methyl" part of its name and distinguishes it from resorcinol without that substitution.

2-METHYLRESORCINOL: what it is

2-METHYLRESORCINOL is a small organic molecule in the resorcinol family. It has two hydroxyl groups attached to an aromatic ring and one methyl group; that detail accounts for the "2-methyl" part of its name and distinguishes it from resorcinol without that substitution.

The term does not name an oil or a botanical extract: it identifies a defined chemical substance. Similar-looking names should not be treated as interchangeable, because the methyl group changes the molecule's identity. On an ingredient list, this INCI name points to that specific compound rather than to a plant raw material or a general mixture of phenols.

2-METHYLRESORCINOL: what it does in cosmetics

In hair-colouring products, 2-METHYLRESORCINOL is used for dyeing the hair. The cosmetic result sought from this type of ingredient is a change in hair colour; it is found in both oxidative and non-oxidative hair-dye formulations.

Seeing 2-METHYLRESORCINOL on a label does not, by itself, establish the final shade, grey coverage, or durability of the colour. Those results depend on the full dye combination and on how the product is used. It is not a scalp-treatment or hair-conditioning ingredient; its relevant cosmetic use here is hair colouring.
