Ingredient review
Methyl Decylideneaminobenzoate
INCI: METHYL DECYLIDENEAMINOBENZOATE
A synthetic UV filter that helps protect skin from sun damage, but is less common in modern formulations due to availability of newer alternatives.
In plain English
Methyl Decylideneaminobenzoate is a man-made sunscreen ingredient that absorbs UV rays before they can harm your skin. It works like a sponge for ultraviolet light, converting it into heat that then safely dissipates. You'll find it in some sunscreens and daily moisturizers with SPF, though it's not as widely used as newer filters like avobenzone or octocrylene.

Quick decision guide
Useful, but context matters
Methyl Decylideneaminobenzoate 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 Decylideneaminobenzoate.
- 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 designed to absorb UVB and some UVA radiation. It belongs to the aminobenzoate family of UV filters, which are chemically similar to PABA (para-aminobenzoic acid) but modified for better stability and safety.
How it works
When applied to the skin, the molecule absorbs high-energy UV photons and releases the energy as lower-energy heat. This prevents the UV radiation from penetrating deeper into the skin and causing sunburn, DNA damage, or premature aging.
Pros
Effective UVB protection
Absorbs UVB rays efficiently, reducing the risk of sunburn and immediate skin damage.
Lightweight feel
Typically leaves a less greasy finish compared to some mineral sunscreens, making it comfortable for daily wear.
Cons and cautions
Moderate photostability
Can degrade faster under prolonged sun exposure, requiring reapplication more frequently than newer filters.
Limited UVA coverage
Provides less protection against UVA rays, which are linked to aging and deeper skin damage, so it's often combined with other filters.
Best for
- People looking for affordable sun protection
- Those with normal to oily skin types
Use caution if
- Individuals with known sensitivity to aminobenzoate compounds
- Those seeking very high UVA protection
Usage tips
Safety summary
Generally recognized as safe for topical use at concentrations up to 10%. Mild irritation is rare but possible. Not recommended for those with known allergies to aminobenzoate compounds.
Research notes
Limited recent research; older studies confirm UVB absorption efficacy. More data is needed on long-term photostability and environmental effects.
Common label clues
- Typical concentration
- Up to 10% in leave-on products
- Regulatory status
- Approved as a UV filter in some countries, but not commonly used in the US or EU where more modern filters are preferred. Always check local regulations.
- Common uses
- Sunscreens, Moisturizers with SPF, Cosmetics with sun protection
- Environmental note
- Synthetic UV filters can accumulate in waterways; however, this specific ingredient has limited environmental impact data available.
Good to know
- Often listed under INCI name Methyl Decylideneaminobenzoate on product labels
- May be found in older sunscreen formulations or imported products
