The ingredients 2-Methylresorcinol can be used as a highly effective and very safe substitute for Resorcinol in hair colour, but are often not used because these non-toxic substitutes are generally much more expensive and difficult to procure and stabilize.
NATURIGIN does not contain the average used in hair colours Resorcinol because the ingredients have a skin deep (high) hazard rating. To compare the ingredients 2-Methylresorcinol is a Non-Toxic ingredients that contain the word Resorcinol but has a very low rate (2% or less).
