What it is
Cyclohexyl Butyrate is a synthetic ester formed from cyclohexanol and butyric acid. It is used exclusively as a fragrance ingredient to impart a fruity, sweet, and slightly floral aroma to cosmetic products.
How it works
In a cosmetic product, Cyclohexyl Butyrate acts as a fragrance component. It evaporates from the skin's surface, releasing its scent molecules into the air. It does not have any active skincare function like moisturizing, exfoliating, or protecting the skin.
Pros
Pleasant scent
Adds a sweet, fruity aroma that can make your skincare routine feel more luxurious and enjoyable.
Low irritation risk
At the tiny concentrations used in cosmetics, it rarely causes irritation for most people, though patch testing is wise if you're sensitive.
Cons and cautions
No skin benefit
This ingredient is purely for fragrance. It does not hydrate, soothe, or improve your skin's health in any way.
Potential allergen
Like all fragrance ingredients, it can trigger allergic reactions or contact dermatitis in some individuals, especially with repeated use.
Best for
- Anyone who enjoys lightly fragranced products and has no history of fragrance allergies
- Those looking for a synthetic, consistent scent profile in their routine
Use caution if
- Individuals with known fragrance allergies or very sensitive, reactive skin
- Anyone following a fragrance-free skincare routine
Usage tips
Safety summary
Cyclohexyl Butyrate is considered safe for use in cosmetics at the low concentrations typical for fragrance. It has a low irritation and sensitization potential for the general population, but like all fragrance ingredients, it can cause allergic reactions in susceptible individuals.
Research notes
Safety assessments by fragrance industry panels (e.g., RIFM) have reviewed Cyclohexyl Butyrate and found it safe for its intended use. There is limited independent research on this specific ester, but it is structurally similar to other well-studied fragrance esters with good safety profiles.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) as a fragrance component.
- Regulatory status
- Approved for use as a fragrance ingredient in cosmetics in the EU, US, and many other regions, subject to concentration limits set by IFRA.
- Common uses
- Fragranced skincare, Body lotions, Perfumes, Cleansers
- Environmental note
- As a synthetic compound, its environmental persistence is low, but it is not biodegradable in all conditions. Sourcing is not a concern as it is manufactured.
Good to know
- Cyclohexyl Butyrate is often part of a complex fragrance blend, so its scent may not be noticeable on its own.
- Fragrance ingredients are regulated by the International Fragrance Association (IFRA) for safe use levels.
