INCI: Methyl Methylpentylidene-Aminobenzoate

A synthetic UVB filter that helps protect skin from sunburn, but it's less common in modern sunscreens due to newer alternatives.

In plain English

This is a man-made ingredient that works like a tiny umbrella for your skin. It absorbs UVB rays (the kind that cause sunburn) and turns them into harmless heat. You'll find it in some sunscreens and SPF products, though it's not as popular today because newer filters offer broader protection and feel lighter on the skin.

Quick decision guide

Useful, but context matters

Methyl Methylpentylidene-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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Methyl Methylpentylidene-Aminobenzoate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic organic compound specifically designed to absorb ultraviolet B (UVB) radiation. It belongs to the aminobenzoate family of UV filters, which have been used in sunscreens for decades.

How it works

When applied to the skin, the molecule absorbs UVB photons and converts them into lower-energy heat, preventing the radiation from penetrating deeper into the skin and causing damage like sunburn or DNA harm.

Pros

Effective UVB blocker

Absorbs UVB rays efficiently, helping prevent sunburn and short-term skin damage.

Stable in formulations

Works well with other sunscreen ingredients and maintains its protective ability over time.

Cons and cautions

No UVA protection

Leaves skin vulnerable to UVA rays, which cause premature aging and deeper skin damage, so it must be paired with other filters.

Less common today

Newer UV filters offer broader spectrum protection and better cosmetic elegance, making this ingredient less popular in modern sunscreens.

Best for

  • People looking for a basic UVB filter in a sunscreen formula
  • Those who tolerate synthetic sunscreens well and want affordable sun protection

Use caution if

  • Individuals with very sensitive or reactive skin who may prefer mineral-based UV filters like zinc oxide or titanium dioxide

Usage tips

Always use a sunscreen that also contains UVA filters (like avobenzone or zinc oxide) for broad-spectrum protection.
Apply generously and reapply every two hours when exposed to direct sun for best results.

Safety summary

Generally recognized as safe for topical use at approved concentrations. Mild irritation is possible but rare. It does not provide UVA protection, so it should always be combined with other filters.

Research notes

Moderate evidence supports its effectiveness as a UVB filter. Few recent studies focus specifically on this ingredient, as newer filters have become more common in research and product development.

Common label clues

Typical concentration
Up to 10% in leave-on products
Regulatory status
Approved for use as a UV filter in sunscreens in many countries, including the EU and Asia, but less commonly used in the US due to FDA review status.
Common uses
Sunscreens, Daily moisturizers with SPF, Makeup with sun protection
Environmental note
Some synthetic UV filters have raised concerns about coral reef safety, but specific data on this ingredient is limited. Check local regulations if you are near marine environments.

Good to know

  • This ingredient is sometimes listed under different trade names on labels, so check the INCI list carefully.
  • It is not a mineral sunscreen ingredient, so it won't leave a white cast like zinc oxide.
