118-58-1 ●
TL;DR. This ingredient is used primarily as a fragrance component and fixative, helping scent last longer. It can also act as a solvent for perfume materials and a minor UV absorber in some formulas.
What does 118-58-1 do in a cosmetic formula?
This ingredient is used primarily as a fragrance component and fixative, helping scent last longer. It can also act as a solvent for perfume materials and a minor UV absorber in some formulas.
Is 118-58-1 clean?
From a clean-beauty perspective, this ingredient is a recognized fragrance allergen in the EU and is subject to disclosure thresholds and IFRA use limits because it can sensitize some skin. It is acceptable in many frameworks, but it is not a low-friction choice for fragrance-allergen-sensitive positioning.
Is 118-58-1 sustainable?
This material is commonly petrochemical or mixed-source, although it can occur naturally in some aromatic extracts. It is generally biodegradable, but its moderate lipophilicity and aquatic-classification profile create more sustainability caveats than simpler, low-accumulation fragrance materials.
Is 118-58-1 COSMOS-approved?
COSMOS does not generally permit it as an isolated synthetic fragrance molecule, but it can be present as a natural constituent within a compliant natural aromatic material or where the raw-material route meets COSMOS fragrance rules. Its Green Chemistry fit is partial, since renewable sourcing is possible, biodegradability is favorable, and aquatic-profile caveats remain.
How does 118-58-1 work chemically?
The molecule is an aromatic ester with two ring systems, a phenolic hydroxyl group, molecular weight about 228.2 Da, and logP around 4.3, which explains its low water solubility and scent-fixative behavior. Typical finished-product levels are usually low and governed by IFRA category limits, with EU allergen disclosure triggered above 0.001% in leave-on products and 0.01% in rinse-off products.
