TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE ●
TL;DR. This ingredient is used as a fragrance material, mainly to add a woody, amber, musky scent profile. It can also act as a long-lasting base note that helps a fragrance accord persist on skin or hair.
What does TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE do in a cosmetic formula?
This ingredient is used as a fragrance material, mainly to add a woody, amber, musky scent profile. It can also act as a long-lasting base note that helps a fragrance accord persist on skin or hair.
Is TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic fragrance component with documented sensitization potential and IFRA usage limits. It is also among fragrance allergens that may require declaration in the EU when present above threshold levels.
Is TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE sustainable?
This material is typically petrochemical-derived and is not a strong fit for renewable sourcing goals. It is expected to have limited ready biodegradability and has aquatic-environment classification concerns, so its environmental profile is less favorable than readily biodegradable fragrance materials.
Is TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE COSMOS-approved?
This ingredient is not permitted in COSMOS-natural or COSMOS-organic formulas when used as a conventional synthetic fragrance molecule. Its petrochemical sourcing, limited biodegradability, and persistence concerns give it weak alignment with Green Chemistry priorities.
How does TETRAMETHYL ACETYLOCTAHYDRO NAPHTHALENE work chemically?
The molecule is a highly substituted bicyclic ketone, which explains its low volatility, substantivity, and use as a long-lasting base-note odorant. It is generally stable across normal cosmetic pH ranges and is used at low fragrance-compound levels under IFRA category-specific concentration limits.
