Ingredient review
Dihydrojasmone
INCI: Dihydrojasmone
Dihydrojasmone is a synthetic jasmine-like fragrance that adds a pleasant scent to products but offers no skincare benefits and may be a concern for those with fragrance sensitivities.
In plain English
Dihydrojasmone is a man-made chemical that smells like jasmine flowers. It is added to skincare and beauty products to make them smell nice. It does not moisturize, treat, or improve your skin in any way—it is purely for scent. Because it is a fragrance ingredient, it can sometimes cause irritation or allergic reactions in people with sensitive skin or fragrance allergies.

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 Dihydrojasmone.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Dihydrojasmone is a synthetic organic compound belonging to the cyclopentenone family. It is created in a lab to mimic the scent of jasmine and is widely used as a fragrance ingredient in cosmetics, perfumes, and personal care products.
How it works
In a cosmetic product, dihydrojasmone works solely as a fragrance agent. It evaporates from the skin's surface, releasing a floral, jasmine-like aroma that enhances the sensory experience of using the product. It does not interact with skin cells or provide any functional skincare benefit.
Pros
Pleasant floral scent
Dihydrojasmone provides a warm, jasmine-like fragrance that many people find appealing, making skincare routines more enjoyable.
Stable and consistent
As a synthetic ingredient, it offers a uniform scent profile batch after batch, unlike natural jasmine extracts which can vary with harvest conditions.
Cons and cautions
Potential irritant for sensitive skin
Fragrance ingredients, including dihydrojasmone, are common triggers for contact dermatitis and skin reactions, especially for those with eczema or rosacea.
No skincare benefit
This ingredient adds only scent—it does not hydrate, soothe, protect, or improve skin health in any way, so it is purely cosmetic.
Best for
- People who enjoy floral-scented skincare and have no history of fragrance allergies
- Those looking for a consistent, stable jasmine scent without the variability of natural extracts
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone following a fragrance-free skincare routine to minimize irritation risk
Usage tips
Safety summary
Dihydrojasmone is generally recognized as safe for use in cosmetics at typical low concentrations. However, it can cause skin sensitization and allergic reactions in susceptible individuals. Regulatory bodies require labeling when present above certain levels to help consumers with fragrance allergies avoid it.
Research notes
Research on dihydrojasmone primarily focuses on its fragrance properties and potential as a skin sensitizer. It is listed as a known allergen by the European Scientific Committee on Consumer Safety (SCCS) and is included in the EU's list of 26 fragrance allergens that must be labeled. Studies show it has a low to moderate sensitization potential compared to other common fragrance ingredients.
Common label clues
- Typical concentration
- Typically used at very low levels (under 1%) in leave-on and rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. It must be listed as a fragrance allergen if present above certain thresholds in the EU (above 0.01% in leave-on products).
- Common uses
- Fragranced skincare, Perfumes, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, dihydrojasmone is produced through chemical synthesis. Its environmental persistence and bioaccumulation potential are considered low, but like all fragrance ingredients, it may contribute to aquatic toxicity if not properly treated in wastewater.
Good to know
- Dihydrojasmone is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is considered a moderate-strength allergen by some dermatological sources, though reactions are not universal.
