Tetramethylacetyloctahydronaphthalenes ●
TL;DR. This ingredient is a synthetic fragrance material used to add a long-lasting woody, amber note. It also helps give fragrance blends diffusion and staying power at low levels.
What does Tetramethylacetyloctahydronaphthalenes do in a cosmetic formula?
This ingredient is a synthetic fragrance material used to add a long-lasting woody, amber note. It also helps give fragrance blends diffusion and staying power at low levels.
Is Tetramethylacetyloctahydronaphthalenes clean?
From a clean-beauty perspective, it carries friction because it is a synthetic fragrance allergen now subject to expanded EU allergen labeling thresholds. It is generally managed through IFRA limits rather than treated as broadly unproblematic.
Is Tetramethylacetyloctahydronaphthalenes sustainable?
This material is typically petrochemical-derived and is not a strong fit for renewable-sourcing goals. Its hydrophobic, persistent profile can lead it to partition into sludge or sediment after use, even though cosmetic use levels are usually low.
Is Tetramethylacetyloctahydronaphthalenes COSMOS-approved?
It is not permitted as a fragrance component in COSMOS-natural or COSMOS-organic products, which require fragrance materials to meet natural-origin criteria. Its Green Chemistry alignment is weak because it relies on synthetic petrochemical chemistry and has limited biodegradability.
How does Tetramethylacetyloctahydronaphthalenes work chemically?
The molecule is a neutral, hydrophobic polycyclic ketone, usually supplied as a mixture of closely related stereoisomers. It is stable across normal cosmetic pH ranges, oil-soluble rather than water-soluble, and typically used through the fragrance phase under IFRA category limits.
