Ingredient review
Morpholinomethylphenyl Hydroxyphenylamino Thienopyridine
INCI: MORPHOLINOMETHYLPHENYL HYDROXYPHENYLAMINO THIENOPYRIDINE
A synthetic UV filter with limited public research; may offer broad-spectrum protection but is not widely used in mainstream products.
In plain English
This is a man-made chemical that absorbs ultraviolet (UV) light, especially in the UVA range. It is added to sunscreens and some anti-aging creams to help prevent sun damage. Because it is relatively new and not as common as ingredients like avobenzone or zinc oxide, there is less independent research on its long-term safety and effectiveness.
Review score
Safety, usefulness, and evidence
Useful in the right context, but not low-maintenance
The evidence base is still emerging, so marketing claims deserve extra caution.
Main practical flags: irritation is moderate; clogging risk is low.

Quick decision guide
Read the cautions before using
Morpholinomethylphenyl Hydroxyphenylamino Thienopyridine can be useful, but watch for some irritation potential.
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 Morpholinomethylphenyl Hydroxyphenylamino Thienopyridine.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic organic compound designed to absorb UV radiation, particularly in the UVA spectrum (around 340–400 nm). It belongs to a class of chemicals called thienopyridines, which are not typical in cosmetics.
How it works
When applied to the skin, the molecule absorbs UV photons and converts them into harmless heat, preventing the energy from damaging skin cells. It may also help stabilize other UV filters in a formula.
Pros
UVA protection
Absorbs UVA rays that contribute to skin aging and pigmentation, offering a layer of defense beyond UVB.
Potential stabilizer
May help other sunscreen ingredients remain effective longer when exposed to sunlight.
Cons and cautions
Limited research
There are few peer-reviewed studies on this specific compound in cosmetic formulations, making it hard to fully assess long-term safety.
Possible irritation
As a synthetic chemical, it may cause stinging or redness in people with sensitive skin, especially at higher concentrations.
Best for
- People seeking broad-spectrum sun protection in a synthetic filter
- Those who tolerate chemical sunscreens well
Use caution if
- Individuals with very sensitive or reactive skin
- Anyone preferring mineral-based sunscreens
Usage tips
Safety summary
Safety data is limited. It is not a common ingredient in widely available products, and no major regulatory body has issued a definitive safety review for cosmetic use. Caution is advised for sensitive skin.
Research notes
Available research is sparse and mostly from patent literature or manufacturer studies. Independent clinical trials on human skin are lacking.
Common label clues
- Typical concentration
- Typically 0.5% to 3% in leave-on products
- Regulatory status
- Not currently approved as a sunscreen active ingredient by the US FDA. May be used in some countries under local regulations, but always check local laws.
- Common uses
- Sunscreens, Anti-aging creams, Day creams
- Environmental note
- As a synthetic compound, its environmental persistence and impact on aquatic life are not well studied. Reef-safe status is unknown.
Good to know
- This ingredient is not commonly listed on sunscreen labels in the US or EU; it appears more often in Asian or experimental formulations.
- Its long chemical name often indicates a complex synthetic molecule that may have multiple functions.
