The Research Institute for Fragrance Materials (RIFM) has concluded that 2-Methyl-4(2,2,3-trimethyl-3-cyclopentenyl)butanol, a synonym for this ingredient, is safe for use at current levels in everyday products. However, PubChem data highlights a GHS classification for skin irritation (H315) in 11.4% of reports for 3-Cyclopentene-1-butanol, beta,2,2,3-tetramethyl-, suggesting a potential for dermal irritation.
