Latest SCCS Decisions: What Cosmetic Brands Need to Know About Ingredient Safety

Between November 14‍ and ⁤November 20, 2025,​ the EU Scientific ​Committee‍ on Consumer Safety (SCCS) published six new reports ​after its October 30 plenary session. A⁤ major update includes the⁢ conclusive ‌ assessment of tea tree oil’s safety ⁣in cosmetics. This review followed the⁣ European⁢ Chemicals ​Agency’s RAC decision in 2023, assigning tea tree oil the “Repr.​ 1B” label under CLP rules. That​ classification paved the way for⁣ a⁢ possible restriction under Article 15(2)(d) ⁢of EU Cosmetics Regulation, ‍leading⁣ the SCCS to examine tea tree oil’s continued use‌ in cosmetic products. The final verdict essentially confirms ​the draft conclusions from June 2025, stating that tea⁢ tree ⁣oil is permitted only in limited ⁣concentrations: up to​ 2.0% ⁢in ​ shampoo, 1.0% ‍in ‍shower ⁣gels, 1.0% in face washes, and ⁤0.1% in‌ face creams. ⁣These ‍limits apply only to⁢ tea tree oil matching ⁤ISO 4730:2017 standards and used by adults. ‌Inhalable formats, including sprays and aerosols, remain excluded to prevent respiratory‍ risk.

SCCS Releases BHA Safety guidance

The committee released a draft opinion on butylated hydroxyanisole‌ (BHA),wich is​ not yet regulated in the EU Cosmetics ​Regulation. The⁣ SCCS determined that BHA is considered safe for use in leave-on and ‌rinse-off products-restricted to ⁢dermal application-at levels up to⁢ 0.07%. The ⁤review does‌ not address⁤ products intended for ingestion or inhalation. ‌Stakeholders are invited to submit comments until January 19,2026.

Review of Hair Colorants: Basic ⁣Brown 16 and Basic Blue 99

Evaluations of the hair‌ dyes ⁤Basic⁣ Brown 16 (CAS ‌26381-41-9) and ⁣Basic Blue 99 (CAS 68123-13-7) indicate‌ that their use in non-oxidative dye formulations cannot be considered safe,⁢ according‍ to SCCS findings. Scientific analysis identified possible genotoxic and⁢ mutagenic ‍properties. Neither of these ingredients is⁣ currently approved under Annex III, which ​lists permitted hair dye substances. Documents detailing the SCCS findings ‍on these colorants⁣ are also open for public ⁢input until January 19, 2026.

CBD Assessment: Preliminary findings

The legal status⁣ of cannabidiol⁤ (CBD) in cosmetic products remains ⁤uncertain, as ‌it is not specifically regulated under current EU Cosmetics Regulation.​ Entry 306 of Annex II bans “narcotics, natural and ​synthetic” ‍as defined by the 1961 UN Single Convention. The 2020 case C-663/18 ​at the European Court of Justice found the CBD reviewed ⁣in the case was‌ not a narcotic,​ but confirmed public health restrictions could apply if justified. Rising use of CBD in consumer products led the SCCS to ⁤examine its safety, including potential contamination with other cannabinoids such⁣ as ⁣THC.⁣ The ⁤preliminary review-open for stakeholder responses through ​January 21, 2026-states that CBD levels up to 0.19% are allowed in topical and oral cosmetic ‍formulations, ​whether CBD​ is the only cannabinoid or used in ‍combination. ⁣Additionally, THC residuals must not​ exceed ​0.00025%. The SCCS opinion excludes ​inhalable products.

Update on Preservatives with Mercury Compounds

The latest ​SCCS draft advice covers the⁢ use of thiomersal and⁣ phenylmercuric‍ salts⁢ (including borate‌ forms), both ​of which are‍ currently permitted as preservatives in Annex V despite a general prohibition in Annex⁢ II.⁢ The ​SCCS review concluded that permitted concentrations of​ these mercury-based compounds do not meet safety standards and could increase cumulative mercury exposure from cosmetic and non-cosmetic sources. The consultation period for feedback extends until January 21, 2026.
