HEXYL CINNAMIC ALDEHYDE ●
TL;DR. This ingredient is a fragrance material used to add a floral, jasmine-like scent and improve perfume body in skin care, hair care, wash-off products, and fine fragrance.
What does HEXYL CINNAMIC ALDEHYDE do in a cosmetic formula?
This ingredient is a fragrance material used to add a floral, jasmine-like scent and improve perfume body in skin care, hair care, wash-off products, and fine fragrance.
Is HEXYL CINNAMIC ALDEHYDE clean?
It is a regulated fragrance allergen that must be disclosed on EU labels above threshold levels and is managed under IFRA limits because it can sensitize some users. Clean standards generally treat it as acceptable only with clear fragrance disclosure and allergen control.
Is HEXYL CINNAMIC ALDEHYDE sustainable?
This material is typically produced synthetically from petrochemical or mixed-origin aroma-chemical feedstocks, although biobased routes may exist. It is expected to biodegrade, but its hydrophobicity and aquatic-life classification make low-dose use and wastewater fate relevant.
Is HEXYL CINNAMIC ALDEHYDE COSMOS-approved?
It fits COSMOS only when supplied as a natural fragrance component that meets ISO 9235 and IFRA requirements, while the common synthetic aroma-chemical version is not aligned with COSMOS-natural or COSMOS-organic fragrance rules. From a Green Chemistry view, the profile is mixed because it is effective at very low levels, but common sourcing and sensitization concerns reduce alignment.
How does HEXYL CINNAMIC ALDEHYDE work chemically?
The molecule is a lipophilic alpha,beta-unsaturated aromatic it, a structural feature associated with strong odor impact and protein reactivity relevant to skin sensitization. It is usually used at very low fragrance-dose levels, often below 0.1% in finished products, and it should be protected from excessive heat, light, and oxidizing conditions because aldehydes can shift odor profile as they oxidize.
