Butylphenyl methylpropional

CAS: 80-54-6

Overview

Butylphenyl methylpropional ( CAS 80-54-6 ), widely recognized in the fragrance trade as Lilial, is a synthetic aldehyde that delivers a fresh, floral lily-of-the-valley scent profile.

BMHCA has been a benchmark ingredient in fine fragrance and functional product formulation for decades. Regulatory changes in key markets have significantly affected its status.

In fine fragrance, Lilial contributes a clean, powdery floral character and has historically been used as a core building block in both feminine and masculine compositions.

Functional personal care products including shampoos, conditioners, and fabric softeners have relied on BMHCA to deliver substantive scent performance at rinse-off and leave-on stages.

Industrial applications include scenting adhesives, sealants, and polymer compounds where controlled odor masking or product differentiation is required for the final application.

Coatings formulators have also incorporated it to modify or neutralize process-related odors in finished products. This versatility makes it a staple in various chemical sectors.

Butylphenyl methylpropional is supplied as a clear to pale yellow liquid. It is available in fragrance-grade purity, with specifications typically aligned to IFRA standards.

Given current EU regulatory restrictions, buyers should confirm compliant-use documentation and regional availability with their supplier before finalizing any procurement.
