The European Commission’s Scientific Committee on Consumer Safety (SCCS) has adopted its opinion on the use of dihydroxyacetone (DHA) in cosmetic products. The final opinion was published on 9 March 2020.
Dihydroxyacetone is currently not regulated under the Cosmetics Regulation 1223/2009 but based on the available data on the safety of this substance, the SCCS concluded that the use of DHA as a hair colouring ingredient in leave-on, non-oxidative applications up to a maximum concentration of 6.25 %, will not pose a risk to the consumer’s health. Furthermore, the substance is considered safe for use in self-tanning lotions and face creams containing up to a maximum concentration of 10 % DHA.
SCCS Preliminary opinions
The SCCS currently has its preliminary opinion on the safe use of hair dye Indigofera tinctoria (C170) open for comments until 13 March 2020. They are considering the safety of the substance when used in non-oxidative condition hair colouring products as on-head concentrations of up to 25%. Additionally, the SCCS noted that a weak skin sensitisation potential cannot be excluded for this substance.
SCCS Opinions being finalized
The SCCS is finalizing its opinion on the safety of aluminium in cosmetic products. In the light of the new data provided, the second preliminary opinion suggests that the use aluminium at 6.25% in non-spray antiperspirants and 10.6% in spray antiperspirant, is safe. The use of aluminium in other cosmetic products, such as toothpaste and lipstick, is suggested to be safe at the concentrations of 2.65% and 0.77%, respectively.
