Ingredient review
Methyl Hydroxy-Methylpentylcyclohexenyl-Methyleneaminobenzoate
INCI: Methyl Hydroxymethylpentylcyclohexenyl Methyleneaminobenzoate
A synthetic UV filter that helps protect skin from sun damage, generally considered safe and low-irritation for most people.
In plain English
This is a man-made ingredient added to sunscreens to absorb UV rays before they can harm your skin. It works like a tiny sponge that soaks up ultraviolet light and turns it into harmless heat. You'll find it in many sunscreens and daily SPF products, especially those labeled 'broad spectrum.'

Quick decision guide
Useful, but context matters
Methyl Hydroxy-Methylpentylcyclohexenyl-Methyleneaminobenzoate 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 Hydroxy-Methylpentylcyclohexenyl-Methyleneaminobenzoate.
- 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 UV radiation, specifically in the UVB and some UVA range. It is a type of aminobenzoate derivative, chemically modified to improve stability and sun protection performance.
How it works
When applied to the skin, this ingredient absorbs high-energy UV photons and converts them into lower-energy heat, which is then released from the skin. This prevents the UV radiation from penetrating deeper and causing DNA damage, sunburn, or premature aging.
Pros
Effective UVB protection
Absorbs UVB rays efficiently, reducing the risk of sunburn and immediate skin damage.
Good stability
Chemically stable in formulations, meaning it doesn't break down quickly in sunlight, offering longer-lasting protection.
Cons and cautions
Limited UVA coverage
Primarily protects against UVB rays; you need additional UVA filters like avobenzone or zinc oxide for full broad-spectrum protection.
Potential for mild irritation
Although rare, some people with very sensitive skin may experience slight stinging or redness, especially around the eyes.
Best for
- Anyone seeking reliable sun protection
- People with normal to oily skin types
Use caution if
- Those with known allergy to aminobenzoate derivatives
- Individuals with extremely sensitive or reactive skin
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at regulated concentrations. Mild irritation is possible but uncommon. Always patch test if you have sensitive skin.
Research notes
Studies confirm its effectiveness as a UVB filter with good photostability. Research on long-term systemic absorption is limited, but current evidence supports its safety in approved concentrations.
Common label clues
- Typical concentration
- Up to 10% in leave-on products
- Regulatory status
- Approved for use in sunscreens in many countries, including the EU and Asia, with maximum concentration limits typically around 10%. Not currently approved by the FDA for use in the US.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Broad-spectrum sun protection products
- Environmental note
- Some synthetic UV filters have raised concerns about coral reef safety. Check for reef-safe labels if this is a priority for you.
Good to know
- This ingredient is often listed under its INCI name, which can look intimidating but is simply a precise chemical description.
- It is not a nanoparticle and does not leave a white cast like mineral sunscreens.
