Citronellyl Propionate
INCI: Citronellyl Propionate
A synthetic floral-scented ester used to add a fresh, rosy note to products; generally safe at low concentrations but may cause sensitivity in some individuals.
In plain English
Citronellyl propionate is a man-made ingredient that smells like roses and fresh flowers. It's added to lotions, perfumes, and soaps to give them a pleasant scent. Because it's used in tiny amounts, it's usually not a problem for most people, but if you have very sensitive skin or a known fragrance allergy, you might want to check the label.

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

What it is
Citronellyl propionate is an ester formed from citronellol (a natural alcohol found in rose and geranium oils) and propionic acid. It is synthetically produced for consistent quality and safety.
How it works
In a cosmetic product, citronellyl propionate acts solely as a fragrance ingredient. It evaporates from the skin, releasing a floral, rosy scent. It does not provide moisturizing, cleansing, or other functional benefits.
Pros
Pleasant floral scent
Adds a fresh, rosy note that many people find appealing in lotions, perfumes, and body washes.
Low irritation potential
At typical use levels, it is considered a low irritant for most skin types, making it a common choice in fragrance blends.
Cons and cautions
Potential allergen
As a fragrance ingredient, it can cause allergic reactions or contact dermatitis in sensitive individuals, especially with repeated use.
No skincare benefit
It provides only scent and does not hydrate, protect, or improve the skin in any way.
Best for
- People who enjoy floral-scented products
- Those without known fragrance sensitivities
Use caution if
- Individuals with a known allergy or sensitivity to fragrance ingredients
- Those with very sensitive or reactive skin
Usage tips
Safety summary
Citronellyl propionate is considered safe for use in cosmetics at the low concentrations typically employed. The main safety concern is its potential to act as a skin sensitizer in people with fragrance allergies. Regulatory bodies have reviewed it and found no significant toxicity or carcinogenicity concerns.
Research notes
Research on citronellyl propionate is limited, but it is structurally similar to other fragrance esters that have been well-studied. The Research Institute for Fragrance Materials (RIFM) has evaluated it and concluded it is safe for use in fragrances under current exposure levels. No major clinical studies on its cosmetic effects are available.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng database) with no specific concentration restrictions, though it must be listed as a fragrance allergen in the EU if present above 0.01% in leave-on products.
- Common uses
- Fragranced lotions, Perfumes, Body washes, Hair products
- Environmental note
- As a synthetic ester, it is not derived from natural sources, but it is biodegradable and does not persist in the environment at typical use levels.
Good to know
- Citronellyl propionate is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is approved for use in cosmetics by major regulatory bodies including the FDA and the European Commission.
