About

A phenolic antimicrobial agent restricted in EU cosmetics due to skin sensitization potential; commonly derived from carvacrol and used in limited concentrations.

ISOPROPYL CRESOLS are restricted under EU Cosmetics Regulation (EC) No 1223/2009 Annex III, entry V/38, limiting their use in cosmetic products. The phenolic structure confers antimicrobial properties but also raises concerns for skin and eye irritation, particularly as a potential sensitizer. The restriction profile in the EU indicates these compounds require careful concentration control and are not permitted for unrestricted cosmetic use.

Skin benefits

  • Antimicrobial preservative function in limited formulations

Known concerns

  • Skin sensitizer
  • EU Annex III restricted — concentration limits apply
  • Phenolic compounds may cause skin/eye irritation
