Butylphenyl Methylpropional

TL;DR. This ingredient is a synthetic fragrance material used to give floral, lily-like scent character and to round out perfume blends in beauty and personal care products.

What does Butylphenyl Methylpropional do in a cosmetic formula?

This ingredient is a synthetic fragrance material used to give floral, lily-like scent character and to round out perfume blends in beauty and personal care products.

Is Butylphenyl Methylpropional clean?

This ingredient has major clean-standard friction because it is prohibited in EU and UK cosmetics due to its reproductive-toxicity classification. It is also treated as a fragrance allergen of concern, so DARE rates it as a red-tier material rather than a routine scent component.

Is Butylphenyl Methylpropional sustainable?

This material is typically petrochemical-derived and is not a strong fit for renewable sourcing goals. Its environmental profile is weaker than readily biodegradable natural fragrance components, with aquatic and persistence concerns contributing to its poor standing.

Is Butylphenyl Methylpropional COSMOS-approved?

It is not permitted in COSMOS-natural or COSMOS-organic products. From a Green Chemistry perspective, it scores poorly because it relies on synthetic petrochemical chemistry and has regulatory endpoints that outweigh any formulation benefit.

How does Butylphenyl Methylpropional work chemically?

The molecule is an aromatic aldehyde with a bulky alkyl-substituted ring, which gives high odor impact at very low fragrance-use levels. Aldehydes can oxidize over time and may interact with amine-containing ingredients, so fragrance systems using this chemistry historically required careful stability and packaging control.
