February 2017 EU Cosmetic Regulatory Update: Benzophenone-3 & Hair Dye Substances

On February 10, 2017, the EU Commission published the amendments to Annex III (restricted substances) and Annex VI (UV-filters) of Cosmetics Regulation EC No. 1223/2009 to decrease the maximum allowable concentration of benzophenone-3 in cosmetic products and various hair dye substances.

 

Benzophenone-3

In December 2008, the Scientific Committee on Consumer Safety (SCCS) concluded in its opinion that the use of Benzophenone-3 as a UV-filter at a maximum concentration of 6% w/w in cosmetic sunscreens and 0.5% w/w in all types of cosmetic products to protect the formulation is generally safe for human health, apart from its potential for contact allergy & photoallergy. This became the basis for the amendment of the current maximum concentration of 10% w/w for Benzophenone-3 as UV-filter to 6% w/w in cosmetic products.

 

This change granted the industry 6 months from its entry into force or until the 3rd of September 2017 to take necessary measures to make the required adjustments to their product formulations, withdraw non-compliant products already available on the market, and place only the products that comply with the new maximum allowable concentration of Benzophenone-3 on the market.

 

Hair Dye Substances

In 2001 the SCCS concluded that the potential risks of the use of hair dyes were of concern and recommended an overall safety assessment strategy for hair dye substances including the requirements for testing substances used in hair dye products for their potential genotoxicity or carcinogenicity.

 

The SCCS subsequently assessed the safety of individual hair dye substances. One of their conclusions was that oxidative hair dye substances which are listed below (found in Annex III) are considered safe for use in hair dye products and can be safely used by professionals in products intended for colouring eyelashes.

  • Toluene-2,5-Diamine
  • Tetraaminopyrimidine Sulfate
  • Hydroxyethyl-p-Phenylenediamine Sulfate
  • 2-Amino-3-Hydroxypyridine
  • p-Aminophenol
  • 2-Methylresorcinol

 

Therefore their use should be allowed in products intended for colouring eyelashes. However, in order to avoid any risk connected with the self-application of products intended for colouring eyelashes by consumers, they should be allowed for professional use only with appropriate warnings printed on the labelling.

 

Also, separate reference numbers are created in Annex III for N,N’-Bis(2-Hydroxyethyl)-2-Nitro-p-Phenylenediamine (now 8c) and 2,6-Dihydroxyethylaminotoluene (now 9b) since they were previously regulated under generic entries 8 and 9 and they have new restrictions on their use as summarized below.

Refe-rence Number INCI Name Product type, body

Maximum conc. in ready use prep. Other
8c N,N′-Bis(2-Hydroxy-ethyl)-2-Nitro-p-Phenylenediamine (a) Hair dye substance

(b) 1.5 %

(a) After mixing under oxidative conditions the maximum concentration applied to hair must not exceed 1.0 %

For (a) and (b):

— Do not use with nitrosating agents

— Max. nitrosamine content: 50 µg/kg

— Keep in nitrite-free containers

9b 2,6-Dihydroxyethyl-aminotoluene Hair dye substance

in oxidative hair dye

products

  After mixing under oxidative conditions

the maximum concentration applied

to hair must not exceed 1.0 %

— Do not use with nitrosating agents

— Max. nitrosamine content: 50 µg/kg

— Keep in nitrite-free containers

 

Furthermore, changes in the restriction on the following hair dye substances for non-oxidative & oxidative hair dye products were made:

  • In non-oxidative hair dye products:
    • HC Red No.17 – max. concentration is now 0.5%
    • HC Yellow No.17 – max. concentration is now 0.5%
    • Basic Brown 17 – max. concentration is now 2.0%
    • Basic Blue 124 – max. concentration is now 0.5%
  • In oxidative hair dye products:
    • 1-Hexyl 4,5-Diamino Pyrazole Sulfate – after mixing under oxidative conditions, the maximum concentration applied to hair must not exceed 1.0%
    • 2,5,6-Triamino-4-Pyrimidinol Sulfate – after mixing under oxidative conditions, the maximum concentration applied to hair must not exceed 0.5%
    • Hydroxyethoxy Aminopyrazolopyridine HCl – after mixing under oxidative conditions, the maximum concentration applied to hair must not exceed 2.0 %
    • 3-Amino-2,6-Dimethylphenol – after mixing under oxidative conditions, the maximum concentration applied to hair must not exceed 2.0 %

 

Similar with the amendment on Benzophenone-3, this new regulation for hair dye substances shall enter into force on the 3rd of September 2017 to give time for the industry to adapt to the new requirements and to phase out products concerned which do not comply with those requirements. On the other hand, compliance on changes on the labelling information can be made until the 3rd of March 2018.
