Ingredient review
Methyl Methylcyclohexenecarboxylate
INCI: METHYL METHYLCYCLOHEXENECARBOXYLATE
A synthetic fragrance ingredient that adds a pleasant scent but offers no skincare benefits; safe for most people but may cause sensitivity in those with fragrance allergies.
In plain English
This is a man-made chemical used to make products smell nice—like a sweet, floral note. It doesn't moisturize, treat, or protect your skin; it's purely for scent. If you have sensitive skin or a known fragrance allergy, you might want to avoid it, but for most people it's fine in the tiny amounts used.

What it is
A synthetic ester compound created in a lab to produce a sweet, floral aroma. It is not derived from plants or natural sources.
How it works
It evaporates from the skin or hair, releasing its scent molecules into the air. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.
Pros
Pleasant scent
Adds a sweet, floral note that many people find appealing in lotions, perfumes, and body washes.
Low irritation for most
At typical low concentrations, it rarely causes problems for people without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient does nothing for your skin's health—no hydration, protection, or anti-aging effects.
Potential allergen
Like many synthetic fragrances, it can trigger allergic reactions or irritation in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented products and have no history of fragrance allergies
- Those looking for a pleasant-smelling cosmetic experience
Use caution if
- Individuals with known fragrance allergies or very sensitive skin

Usage tips
Safety summary
Generally recognized as safe for use in cosmetics at low concentrations. The main risk is allergic contact dermatitis in sensitive individuals. No known carcinogenic or reproductive toxicity concerns based on current data.
Research notes
Limited peer-reviewed research specifically on this compound, but it is structurally similar to other fragrance esters that have been evaluated by safety panels. The International Fragrance Association (IFRA) sets usage limits to minimize sensitization risk.
Common label clues
- Typical concentration
- Typically less than 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US and EU, but must be listed on the label if present. Some countries require allergen labeling for certain fragrance compounds.
- Common uses
- Perfumes, Fragranced lotions, Body washes, Hair products
- Environmental note
- As a synthetic compound, it may not biodegrade quickly. However, its low concentration in rinse-off products limits environmental impact.
Good to know
- Fragrance ingredients are often listed simply as 'fragrance' or 'parfum' on labels, so you may not see this specific name unless the brand discloses it.
- This ingredient is not known to be phototoxic or cause sun sensitivity.
