Stability
While direct stability data for this specific ingredient is limited, a chemically related fragrance, Formoxymethyl isolongifolene, exhibited minor discoloration after three months when subjected to accelerated aging conditions (40°C) within some shampoo formulations. This suggests a potential for color instability in certain product matrices, necessitating careful evaluation during formulation development.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet reviewed this ingredient for safety. A closely related chemical, 2H-2,4a-Methanonaphthalene-8-methanol, 1,3,4,5,6,7-hexahydro-1,1,5,5-tetramethyl-, 8-formate (CAS 61826-52-6), has been reported by numerous companies to the ECHA C&L Inventory as not meeting GHS hazard criteria. This may suggest a lower general hazard profile for related compounds, but this information does not directly confirm the specific safety or sensitization risk of HEXAHYDRO-TETRAMETHYL-METHANONAPHTHALENE-8-METHYL FORMATE.

Verdict
As a pure fragrance ingredient with no known skin benefits and an unreviewed safety profile by CIR, its inclusion in precision skincare formulations is questionable.
