Ingredient review
Benzyl Dimethylamino Morpholinophenyl Butanone
INCI: Benzyl Dimethylamino Morpholinophenyl Butanone
A synthetic UVA filter that helps protect skin from deeper sun damage, but it's not as widely studied as some older filters.
In plain English
This is a man-made ingredient that works like a tiny sponge for UVA rays. UVA rays are the type of sunlight that can cause wrinkles and long-term skin aging. When you apply a product containing this ingredient, it absorbs those rays before they can reach deeper layers of your skin. It's often used alongside other sun filters to give broad-spectrum protection.
Quick decision guide
Useful, but context matters
Benzyl Dimethylamino Morpholinophenyl Butanone 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 Benzyl Dimethylamino Morpholinophenyl Butanone.
- 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 UVA radiation. It belongs to a class of UV filters that convert UV light into harmless heat, preventing it from damaging skin cells.
How it works
When applied to the skin, the molecule absorbs high-energy UVA photons and releases the energy as low-level heat. This prevents the UV radiation from penetrating the skin and causing oxidative stress, collagen breakdown, and DNA damage.
Pros
Strong UVA absorber
Effectively blocks UVA rays that are linked to wrinkles and loss of elasticity, giving you better protection against long-term skin aging.
Good photostability
Unlike some older UVA filters, this ingredient doesn't degrade quickly in sunlight, so your protection lasts longer during sun exposure.
Cons and cautions
Limited global approval
This filter is not yet approved in all countries (e.g., the US FDA has not included it in the approved sunscreen list), so availability may vary.
Less research history
Compared to avobenzone or zinc oxide, there are fewer long-term human studies on this ingredient, which may concern cautious consumers.
Best for
- Anyone looking for broad-spectrum UVA protection in their sunscreen
- People concerned about photoaging and dark spots
Use caution if
- Those with very sensitive skin who react to synthetic UV filters should patch-test first
Usage tips
Safety summary
Generally considered safe for topical use at concentrations up to 10% based on available data. However, long-term human exposure studies are less extensive than for some traditional filters. Patch testing is recommended for sensitive skin.
Research notes
Studies show effective UVA absorption and good photostability. Human safety data is moderate, with no major red flags in current research, but more independent long-term studies would strengthen the evidence base.
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 yet approved by the US FDA. Always follow local sunscreen regulations.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Anti-aging products
- Environmental note
- Some synthetic UV filters have raised concerns about coral reef safety. Research on this specific compound is limited, so if you're reef-conscious, consider mineral sunscreens.
Good to know
- Often combined with other UV filters to provide broad-spectrum (UVA + UVB) protection.
- Check your product's ingredient list to see if this is paired with a UVB filter like octinoxate or homosalate.
