The European Commission’s Scientific Committee for Consumer Safety (SCCS) published its final judgment on the safety of Dihydroxyacetone (DHA) in hair colouring and cosmetic products, ruling it safe but at a maximum concentration of 10%. The final opinion on use of DHA (chemical name 1,3-Dihydroxy-2-propanone) – as a leave-on hair colouring ingredient and in self-tanning creams – was published on March 9, 2020. SCCS recognised that DHA was not regulated under the Cosmetics Regulation (EC) No.1223/2009 but stated that in considering scientific data that includes exposure assessment and toxicological evaluation was safe to use as hair colouring ingredient in leave-on non-oxidative applications at a maximum concentration of 6.25 %.
