Ingredient review
Ethyl Dimethylaminobenzoate
INCI: Ethyl Dimethylaminobenzoate
Ethyl Dimethylaminobenzoate is a synthetic UV absorber that helps sunscreens and other products stay effective under sunlight, but it has moderate irritation potential and is not a primary sunscreen active.
In plain English
Ethyl Dimethylaminobenzoate is a man-made ingredient that absorbs ultraviolet (UV) light. In sunscreens, it works as a booster to help other UV filters last longer and work better. It is also used in nail polishes and some coatings that harden under UV light. While it is effective, it can sometimes cause skin irritation, especially in sensitive individuals, and it is not a standalone sunscreen ingredient.

Quick decision guide
Useful, but context matters
Ethyl Dimethylaminobenzoate can be useful, but watch for some irritation potential.
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 Ethyl Dimethylaminobenzoate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
A synthetic organic compound derived from benzoic acid, designed to absorb UV radiation. It is often used as a photoinitiator in UV-cured products and as a UV stabilizer in sunscreens.
How it works
It absorbs UV light energy and converts it into heat, which reduces the amount of UV radiation that reaches the skin. In sunscreens, it helps protect other UV filters from breaking down, extending the product's sun protection effectiveness.
Pros
Boosts sunscreen stability
Helps other UV filters like avobenzone remain effective longer under sunlight, so your sunscreen stays protective.
Enables fast UV curing
In nail polishes and coatings, it allows quick hardening under UV lamps, saving time and improving durability.
Cons and cautions
Moderate irritation risk
Can cause redness, itching, or stinging on sensitive skin, especially in high concentrations or with repeated use.
Not a standalone sunscreen
On its own, it does not provide broad-spectrum UV protection and must be combined with other filters to be effective.
Best for
- People looking for stable, long-lasting sunscreens
- Those using UV-cured nail products who want efficient curing
Use caution if
- Individuals with sensitive or reactive skin, especially those prone to contact dermatitis
Usage tips
Safety summary
Ethyl Dimethylaminobenzoate is considered safe for use in cosmetics at regulated concentrations, but it can cause skin irritation in sensitive individuals. It is not a primary sunscreen active and should be used in combination with other UV filters. Avoid contact with eyes and broken skin.
Research notes
Studies confirm its effectiveness as a UV absorber and photoinitiator. Research on long-term skin safety is limited, but it is generally recognized as safe when used as directed. Some reports of contact allergy exist, particularly in nail products.
Common label clues
- Typical concentration
- Up to 5% in sunscreens; varies in other applications
- Regulatory status
- Approved for use in cosmetics and sunscreens in many regions, including the EU and the US, but concentration limits may apply. Always check local regulations.
- Common uses
- Sunscreens, Nail polishes, UV-cured coatings
- Environmental note
- As a synthetic compound, it may persist in water systems. Its environmental impact is less studied than some mineral filters, but it is not known to bioaccumulate significantly.
Good to know
- This ingredient is more common in professional nail products than in everyday sunscreens.
- It is not a mineral sunscreen ingredient; it is synthetic and works by absorbing UV light rather than reflecting it.
