Ingredient review
Methyl Trimethylcyclohexenyl Vinyloxirane Carboxylate
INCI: METHYL METHYL-TRIMETHYLCYCLOHEXENYL-VINYLOXIRANE-2-CARBOXYLATE
A synthetic fragrance ingredient that adds scent but offers no skincare benefit; generally safe at low levels but may cause irritation in sensitive individuals.
In plain English
This is a man-made chemical that gives a pleasant smell to lotions, cleansers, and perfumes. It doesn't moisturize, treat, or improve your skin in any way—it's purely there for the scent. Because it's used in tiny amounts, it's usually not a problem, but if your skin is easily irritated by fragrance, you might want to avoid it.

What it is
A synthetic organic compound from the oxirane family, specifically designed as a fragrance ingredient. It is not derived from plants or natural sources.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. In a formula, it is blended at very low concentrations to provide a pleasant fragrance without causing visible irritation for most people.
Pros
Pleasant scent
Provides a subtle, long-lasting fragrance that can improve the sensory experience of a product.
Low irritation for most
At typical use levels, it is well-tolerated by the majority of skin types without causing redness or stinging.
Cons and cautions
No skin benefit
This ingredient does not hydrate, soothe, or protect the skin—it only adds smell.
Potential allergen
Like many synthetic fragrances, it can cause allergic reactions or irritation in people with sensitive skin or fragrance sensitivities.
Best for
- People who enjoy scented skincare and have no history of fragrance allergy
- Those looking for a long-lasting, subtle scent in their products
Use caution if
- Anyone with sensitive, reactive, or eczema-prone skin
- Individuals with a known fragrance allergy or contact dermatitis
