2-METHYL-3-P-CRESYL-PROPIONALDEHYDE

Description

2-Methyl-3-p-cresyl-propionaldehyde, also known as Lilial or Butylphenyl Methylpropional, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This aromatic aldehyde imparts a fresh, floral scent reminiscent of lily of the valley, making it a popular choice in perfumes and cosmetic formulations.

In skincare applications, 2-Methyl-3-p-cresyl-propionaldehyde serves primarily as a fragrance component, enhancing the sensory experience of products. It is typically used in low concentrations, ranging from 0.01% to 0.1% in leave-on products and up to 0.5% in rinse-off formulations.

While effective as a fragrance, this ingredient has been subject to scrutiny due to potential skin sensitization concerns. The European Union has banned its use in cosmetic products as of March 2022, citing reproductive toxicity risks. Formulators and manufacturers are increasingly seeking alternatives to comply with evolving regulations and address consumer safety concerns.

When present in products, 2-Methyl-3-p-cresyl-propionaldehyde may be listed on ingredient labels as Butylphenyl Methylpropional, Lilial, or its full chemical name. Individuals with sensitive skin or fragrance allergies should exercise caution when using products containing this ingredient.
