Ingredient review
Methyl Trimethylhexylidene-Aminobenzoate
INCI: Methyl Trimethylhexylidene-Aminobenzoate
A synthetic UVA filter that helps protect skin from deeper sun damage, but its use is limited outside certain regions.
In plain English
This is a man-made ingredient added to sunscreens to absorb UVA rays, which are the type of sunlight that can cause premature aging and deeper skin damage. It works by converting UV light into heat, which then safely leaves the skin. You'll find it in some sunscreens, especially those designed for broad-spectrum protection, but it's not as common as other filters like avobenzone.

Quick decision guide
Useful, but context matters
Methyl Trimethylhexylidene-Aminobenzoate 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 Trimethylhexylidene-Aminobenzoate.
- 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 that absorbs ultraviolet A (UVA) radiation. It is a derivative of aminobenzoic acid and is designed to be photostable, meaning it doesn't break down quickly in sunlight.
How it works
When applied to the skin, it absorbs UVA light energy and converts it into a small amount of heat, which is then released. This prevents the UV rays from penetrating deeper into the skin and causing damage like collagen breakdown or DNA changes.
Pros
Effective UVA blocker
Absorbs UVA rays that contribute to wrinkles and skin aging, offering deeper protection than some other filters.
Stable in sunlight
Unlike some UV filters that degrade quickly, this ingredient stays effective longer, so your sunscreen doesn't lose power as fast.
Cons and cautions
Not globally approved
It is not approved by the FDA for use in sunscreens in the United States, so you won't find it in US products, limiting your options.
Potential for skin sensitivity
A small number of people may experience redness or irritation, especially if they have very sensitive skin or allergies to similar compounds.
Best for
- People looking for strong UVA protection in sunscreens
- Those who prefer synthetic, non-mineral UV filters
Use caution if
- Individuals with known sensitivity to organic UV filters or aminobenzoic acid derivatives
Usage tips
Safety summary
Generally considered safe for topical use at approved concentrations, with low irritation and comedogenic risk. However, it is not approved in all countries, and rare allergic reactions are possible.
Research notes
Studies show it is an effective UVA filter with good photostability. Research on long-term systemic absorption is limited, but current evidence supports its safety in cosmetic use within regulated limits.
Common label clues
- Typical concentration
- Up to 10% in leave-on products
- Regulatory status
- Approved as a UV filter in the EU and some other regions, but not approved by the US FDA. Always check local regulations.
- Common uses
- Sunscreens, Moisturizers with SPF, Cosmetics with UV protection
- Environmental note
- Some synthetic UV filters have been studied for potential environmental impact on coral reefs, but specific data on this ingredient is limited.
Good to know
- This ingredient is often combined with UVB filters to provide broad-spectrum protection.
- It is more commonly found in sunscreens sold in Europe and Asia than in the US.
