Ingredient review
Methyl Dodecylideneaminobenzoate
INCI: Methyl Dodecylideneaminobenzoate
A synthetic UV filter that helps protect skin from sun damage, but its use is less common than newer alternatives.
In plain English
Methyl Dodecylideneaminobenzoate is a man-made ingredient added to sunscreens to absorb ultraviolet (UV) light, especially UVB rays. When it absorbs UV energy, it converts it into a small amount of heat, which is then released from the skin. This helps prevent the UV radiation from reaching deeper layers of your skin and causing sunburn or long-term damage. It's not as widely used today as some other UV filters, but it can still be found in certain sunscreen formulas.

Quick decision guide
Useful, but context matters
Methyl Dodecylideneaminobenzoate is generally a lower-concern ingredient when the full formula suits your skin.
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 Methyl Dodecylideneaminobenzoate.
- 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
A synthetic organic compound belonging to the aminobenzoate family, designed specifically to absorb UVB radiation (280–320 nm). It is a derivative of para-aminobenzoic acid (PABA), but with a modified structure to improve stability and reduce irritation.
How it works
The molecule contains a conjugated system of alternating single and double bonds that can absorb high-energy UV photons. When UV light hits the molecule, it excites electrons to a higher energy state. The molecule then relaxes back to its ground state by releasing the energy as heat, effectively neutralizing the UV radiation before it can damage skin cells.
Pros
Effective UVB shield
Absorbs UVB rays efficiently, helping to prevent sunburn and reduce the risk of skin damage from short-wave UV radiation.
Formulation flexibility
Can be combined with other UV filters to create a broad-spectrum sunscreen, and its oily nature can help improve the texture of some products.
Cons and cautions
Limited UVA protection
This ingredient primarily blocks UVB rays and offers very little protection against UVA, which is linked to premature aging and deeper skin damage.
Potential photodegradation
May break down when exposed to sunlight over time, reducing its effectiveness unless stabilized with other ingredients in the formula.
Best for
- People looking for additional UVB protection in a sunscreen
- Those who tolerate synthetic UV filters well and want a cost-effective option
Use caution if
- Individuals with known sensitivity or allergy to PABA derivatives (though this ingredient is less likely to cause reactions than PABA itself)
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations in sunscreens. It has low irritation and comedogenic potential. However, due to limited modern usage and data, some prefer better-studied alternatives.
Research notes
Research on this specific ingredient is sparse compared to more common UV filters. Studies on related aminobenzoate compounds indicate effective UVB absorption with low acute toxicity, but long-term human safety data is limited.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on sunscreens
- Regulatory status
- Approved for use in sunscreens in many countries, including the EU and some Asian markets, but not currently listed as a permitted UV filter by the US FDA (as of 2025). Always check local regulations.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Broad-spectrum sun protection products
- Environmental note
- Like many synthetic UV filters, there are concerns about potential environmental impact, particularly on aquatic ecosystems. However, specific data on this ingredient is limited.
Good to know
- This ingredient is a derivative of PABA but is considered less irritating and more stable than the original PABA.
- It is not as commonly used in modern sunscreens as newer filters like octinoxate or avobenzone, but it may still appear in some formulations.
