Ingredient review
Octahydro Tetramethyl Methano Cyclopentacyclopropabenzene Methanol Acetate
INCI: OCTAHYDRO-TETRAMETHYL-METHANO-CYCLOPENTACYCLOPROPABENZENE-4-METHANOL ACETATE
A synthetic fragrance ingredient that adds a woody, amber scent; generally considered safe at low concentrations but offers no skincare benefit.
In plain English
This is a lab-made chemical that smells like wood and amber. It's added to products like lotions and perfumes just for the scent. It doesn't moisturize, treat, or improve your skin in any way—it's purely for fragrance. Because it's used in tiny amounts, it's unlikely to cause problems for most people, but if you have sensitive skin or a fragrance allergy, it might still be a trigger.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic organic compound from the sesquiterpene family, created to mimic the scent of natural woody or amber notes. It is a single molecule with a complex chemical structure, not a natural extract.
How it works
It works by binding to olfactory receptors in the nose, creating the perception of a warm, woody, amber-like scent. In a cosmetic formula, it simply adds fragrance; it has no known active effect on the skin's structure or function.
Pros
Pleasant Scent
Adds a warm, woody, amber-like fragrance that many people find appealing and sophisticated.
Low Irritation Risk
At the very low concentrations used in cosmetics, it has a low potential for skin irritation for most people.
Cons and cautions
No Skincare Benefit
This ingredient does nothing for your skin's health—no hydration, anti-aging, or barrier support. It's purely for scent.
Potential Allergen
Like many fragrance ingredients, it can cause allergic reactions or irritation in people with sensitive skin or fragrance sensitivities.
Best for
- People who enjoy woody, amber fragrances in their products
- Those without fragrance sensitivities looking for a pleasant scent
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone seeking fragrance-free skincare
Usage tips
Safety summary
Generally recognized as safe for use in cosmetics at the low concentrations typical for fragrance ingredients. However, it can be a contact allergen for some individuals, so those with fragrance sensitivities should exercise caution.
Research notes
Safety data is primarily based on its use as a fragrance ingredient, with assessments by bodies like IFRA and RIFM (Research Institute for Fragrance Materials) indicating low acute toxicity and low skin irritation potential at intended use levels. There is limited independent research on long-term topical effects.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to general fragrance safety regulations. The IFRA (International Fragrance Association) sets usage limits to ensure safety.
- Common uses
- Perfumes, Fragranced Lotions, Body Washes
- Environmental note
- As a synthetic compound, its environmental persistence and bioaccumulation potential are not fully documented, but it is used in very small quantities.
Good to know
- This ingredient is often part of a larger 'fragrance' or 'parfum' blend on a label, so you may not see it listed individually.
- It is not derived from plants; it is entirely synthesized in a lab.
