Ingredient review
Trimethylvinylcyclohexylmethyl Acetate
INCI: TRIMETHYL-3-METHYLVINYL-4-VINYLCYCLOHEXYLMETHYL ACETATE
A synthetic scent ingredient that adds a fresh woody note, but offers no skincare benefit and may be unnecessary for sensitive skin.
In plain English
This is a lab-made chemical that gives products a fresh, woody smell. It doesn't moisturize, protect, or treat your skin—it's purely for fragrance. If you have sensitive skin or prefer unscented products, you might want to avoid it because fragrance ingredients can sometimes cause irritation, even if the risk is low for most people.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Trimethylvinylcyclohexylmethyl Acetate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 ester compound created in a lab, used specifically as a fragrance ingredient in cosmetics and personal care products. It belongs to a family of scent chemicals that mimic natural woody or pine-like aromas.
How it works
It evaporates from the skin or hair after application, releasing its scent molecules into the air. It has no active function beyond providing a pleasant smell and does not interact with the skin's barrier or cells in a meaningful way.
Pros
Pleasant scent
Adds a fresh, woody aroma that many find appealing and can improve the overall user experience of a product.
Low irritation for most
At typical low concentrations, it has a low irritation risk for the general population without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient does nothing for your skin's health—no hydration, barrier support, or anti-aging effects. It's purely for smell.
Potential allergen
Like many synthetic fragrance ingredients, it can cause contact dermatitis or allergic reactions in people with fragrance sensitivities, even at low levels.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those looking for a long-lasting woody scent in their products
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone who prefers fragrance-free or hypoallergenic products
Usage tips
Safety summary
Generally recognized as safe for use in cosmetics at low concentrations by industry safety panels. However, like all fragrance ingredients, it carries a small risk of skin sensitization in susceptible individuals.
Research notes
Limited peer-reviewed research specific to this compound. Its safety is inferred from broader studies on synthetic fragrance esters and regulatory evaluations by bodies like the International Fragrance Association (IFRA).
Common label clues
- Typical concentration
- Typically used at very low levels (under 1%) in rinse-off and leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. Subject to fragrance allergen labeling requirements in the EU if present above certain thresholds.
- Common uses
- Fragranced skincare, Body care, Hair care, Perfumes
- Environmental note
- As a synthetic compound, its environmental persistence and biodegradability are not well-documented. Natural alternatives may have a lower environmental footprint.
Good to know
- This ingredient is not a single plant extract but a synthetic molecule designed to replicate a specific scent profile.
- Fragrance ingredients are not required to be individually listed on labels in many regions—they can be grouped under 'parfum' or 'fragrance', so you may not always see this name.
