Is Linalool[3] clean?
From a clean-beauty perspective, it is allowed by many standards but is treated as a declarable fragrance allergen in several regions. Its oxidation products are more associated with skin sensitization, so freshness, packaging, and low use levels matter.
Is Linalool[3] sustainable?
This material can be sourced from essential oils or made synthetically from petrochemical or plant-derived feedstocks. It is generally biodegradable, but the sustainability profile depends on feedstock origin, agricultural inputs, and traceability of the fragrance supply chain.
Is Linalool[3] COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic when it comes from permitted natural aromatic sources and meets fragrance-standard requirements, while synthetic versions generally do not align with natural-certification rules. From a Green Chemistry view, the stronger profile is renewable sourcing, controlled oxidation, and biodegradability.
How does Linalool[3] work chemically?
The molecule is an acyclic monoterpene alcohol with two carbon-carbon double bonds and a tertiary hydroxyl group, which explains both its volatility and oxidation sensitivity. It is typically used at fragrance-level concentrations, and labeling thresholds in the EU are 0.001% in leave-on products and 0.01% in rinse-off products when present above those levels.
