About

Vernaldehyde is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Vernaldehyde (2-methyl-3-(p-tolyl)propanal or p-methyl-dihydrocinnamaldehyde) is a substituted hydrocinnamic aldehyde with a green, slightly floral odor profile. While not as well-studied as cinnamaldehyde, its α-methyl-cinnamaldehyde structure places it within the fragrance allergen class requiring declaration. Available toxicology data show low acute toxicity; the primary regulatory concern is potential for skin sensitization at high concentrations in leave-on products, governed by IFRA limits.

Skin benefits

  • Adds green, floral fragrance notes to cosmetic products

Known concerns

  • Mild fragrance allergen potential
  • Subject to IFRArecommended concentration limits
