SCCS publishes final opinions on the safety of hair dye, anti-perspirant and antidandruff ingredients

The European Commission’s Scientific Committee on Consumer Safety (SCCS) has finalised its opinion on the safety of the hair dye ingredient Indigofera tinctoral and its use in non-oxidative conditions hair colouring products. This opinion was adopted on April 3, 2020.

The SCCS also published the final opinion on the use of aluminium in antiperspirants and cosmetic products and the final opinion on the use of zinc pyrithione for anti-dandruff products. These were both adopted on March 3-4, 2020.


Hair dye – Indigofera tinctoral

The committee considers the hair dye ingredient Indigofera tinctoral to be safe when used in non-oxidative condition hair colouring products at on-head concentrations of up to 25%.

The SCCS did, however, add that a weak skin sensitisation potential cannot be excluded for this ingredient.


The safety of aluminium

The SCCS evaluated the safety of aluminium when used in antiperspirants and other cosmetic products such as toothpastes and lipsticks. They consider the use of this ingredient safe at the following concentrations:

  • 6.25% in non-spray deodorants or non-spray antiperspirants,
  • 10.6% in spray deodorants or spray antiperspirants,
  • 2.65% in toothpaste, and
  • 0.77% in lipstick.

Additionally, the SCCS said that ‘’ The systemic exposure to aluminium via daily applications of cosmetics does not add significantly to the systemic body burden on aluminium from other sources’’. However, the committee acknowledged that they have not taken into account the daily dietary intake of aluminium, which is the major source of aluminium in the population.

Anti-dandruff ingredient – Zinc pyrithione

Based on the final opinion on the safety of zinc pyrithione, the SCCS considers the ingredient to be safe when used as an anti-dandruff in rinse-off hair products up to a maximum concentration of 1 %. This consideration is in line with the conditions laid out in Article 15 (d) of the Cosmetics Regulations (EC) No. 1223/2009 and takes into account all the scientific data provided.
