What is Butylphenyl methylpropional?
Butylphenyl methylpropional (CAS 80-54-6), known in the fragrance trade as Lilial, is a synthetic aldehyde with a fresh, floral lily-of-the-valley scent profile.
Where is Butylphenyl methylpropional used?
- Fine fragrance: clean, powdery floral character and core building block in feminine and masculine compositions
- Personal care: substantive scent performance in shampoos, conditioners and fabric softeners at rinse-off and leave-on stages
- Industrial: odor masking or product differentiation in adhesives, sealants and polymer compounds
- Coatings formulators have incorporated it to modify or neutralize process-related odors.
Good to know: Regulatory changes in key markets have significantly affected its status; given current EU regulatory restrictions, buyers should confirm compliant-use documentation and regional availability with their supplier before procurement.
