Ingredient review
Nylon-611
INCI: Nylon-611
Nylon-611 is a safe, non-irritating synthetic powder that gives makeup and skincare a silky, smooth finish while absorbing excess oil.
In plain English
Nylon-611 is a man-made plastic powder that's added to cosmetics to make them feel silky and smooth on your skin. It's similar to tiny, round beads that roll over your skin, helping makeup glide on easily and blur the look of pores and fine lines. It also soaks up extra oil, which can help keep your face looking matte longer. Because it's synthetic, it's very consistent in quality and doesn't vary like natural ingredients might.

Quick decision guide
Useful, but context matters
Nylon-611 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 Nylon-611.
- 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
Nylon-611 is a synthetic polymer made from two types of nylon monomers (6 and 11). It's produced as a fine, white powder with spherical particles that are designed to be smooth and uniform.
How it works
In a cosmetic product, Nylon-611 acts as a texture enhancer and oil absorber. Its tiny, spherical particles create a physical barrier on the skin that helps fill in uneven texture, making the skin feel soft and look smoother. It also absorbs sebum (skin oil) and can help control shine throughout the day.
Pros
Silky texture
Nylon-611 gives products a luxurious, silky feel that makes them glide on smoothly, improving the user experience.
Oil control
It absorbs excess oil on the skin's surface, helping to reduce shine and keep makeup looking fresh longer.
Cons and cautions
Not natural
As a synthetic plastic, Nylon-611 is not derived from natural sources, which may be a drawback for those seeking clean or natural beauty products.
Environmental persistence
Nylon-611 is not biodegradable and can contribute to microplastic pollution if it enters waterways, though it is not a rinse-off ingredient in most uses.
Best for
- People with oily or combination skin who want a matte finish
- Anyone who enjoys a silky, smooth texture in their makeup or skincare
Use caution if
- Those who prefer 100% natural or biodegradable ingredients
Usage tips
Safety summary
Nylon-611 is considered safe for use in cosmetics. It has low irritation and comedogenic potential, meaning it is unlikely to clog pores or cause skin reactions. However, as a synthetic plastic, it raises environmental concerns.
Research notes
Research on Nylon-611 is limited but consistent. The Cosmetic Ingredient Review (CIR) panel reviewed it and found it safe for cosmetic use. No significant human or animal toxicity has been reported at typical use levels.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe for use in cosmetics at current concentrations.
- Common uses
- Foundations, Powders, Primers, Lipsticks, Sunscreens
- Environmental note
- Nylon-611 is a synthetic polymer and not biodegradable. While it is not typically washed off directly, it can enter the environment through wastewater. Some manufacturers are exploring biodegradable alternatives.
Good to know
- Nylon-611 is different from microbeads used in exfoliating scrubs; it is a fine powder used for texture, not scrubbing.
- It is considered safe by major cosmetic safety panels, including the Cosmetic Ingredient Review (CIR) panel.
