TL;DR. This ingredient is primarily used as a fragrance component, adding a green, fruity, slightly alcoholic note. It can also serve as a minor solvent within fragrance blends.
What does 3-hexanol do in a cosmetic formula?
This ingredient is primarily used as a fragrance component, adding a green, fruity, slightly alcoholic note. It can also serve as a minor solvent within fragrance blends.
Is 3-hexanol clean?
From a clean-beauty perspective, it is usually evaluated as a fragrance material, so transparency and concentration matter. It is not typically treated as a headline fragrance allergen, but small volatile alcohols can be irritating at higher levels or on sensitized skin.
Is 3-hexanol sustainable?
This material may be made from petrochemical feedstocks or produced through bio-based routes such as fermentation or biotransformation. It is expected to biodegrade readily and has low bioaccumulation potential, though it is volatile and can contribute modestly to product VOC load.
Is 3-hexanol COSMOS-approved?
It can align with COSMOS only when the supplied material meets natural fragrance requirements, typically from natural origin feedstocks and compliant processing. Petrochemical versions would not be permitted in COSMOS-natural or COSMOS-organic products, so its alignment depends on sourcing documentation.
How does 3-hexanol work chemically?
The molecule is a small chiral, six-carbon secondary alcohol with moderate water solubility and stronger affinity for fragrance and oil phases. It is usually used at trace fragrance-blend levels, remains stable across normal cosmetic pH ranges, and can slowly oxidize to the corresponding ketone, so closed storage supports odor stability.
