Ingredient review
Nylon-12
INCI: Nylon-12
Nylon-12 is a safe, non-irritating synthetic powder that gives makeup a silky feel and blurs imperfections without clogging pores.
In plain English
Nylon-12 is a man-made powder, similar to tiny plastic beads, that is added to makeup and skincare to make them feel silky and smooth on the skin. It helps absorb extra oil and creates a soft, blurred look on the skin, like a gentle filter. It is not absorbed into the skin and sits on the surface, so it is generally considered safe and non-irritating.

Quick decision guide
Useful, but context matters
Nylon-12 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-12.
- 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-12 is a synthetic polymer, specifically a type of nylon, that is processed into a fine, spherical powder. It is manufactured through chemical polymerization and is not derived from natural sources.
How it works
When applied to the skin, the tiny spherical particles of Nylon-12 roll over the surface, creating a smooth, silky texture. They also scatter light, which helps to soften the appearance of fine lines and pores. Additionally, the powder absorbs excess sebum (oil) and moisture, helping to keep makeup in place and reduce shine.
Pros
Silky texture
Nylon-12 gives products a luxurious, silky feel that glides on smoothly, making application a pleasure.
Oil control
It effectively absorbs excess oil and sebum, helping to keep makeup looking fresh and matte throughout the day.
Cons and cautions
Synthetic origin
As a man-made plastic, it may not be suitable for those seeking a fully natural or organic skincare routine.
Environmental concerns
As a microplastic, Nylon-12 can contribute to plastic pollution if washed down the drain, though it is more common in leave-on products.
Best for
- People with oily or combination skin who want to control shine
- Anyone who enjoys a silky, smooth makeup finish
Use caution if
- Those who strictly avoid synthetic ingredients or microplastics in their routine
Usage tips
Safety summary
Nylon-12 is considered safe for cosmetic use. It is non-irritating, non-sensitizing, and does not clog pores. The primary concern is its environmental impact as a microplastic.
Research notes
Research indicates Nylon-12 is safe for topical use. Studies show it does not penetrate the skin and has a low potential for irritation or allergy. Environmental studies raise concerns about microplastic accumulation in ecosystems.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and the European Commission, with no known safety concerns at typical use levels.
- Common uses
- Foundations, Powders, Primers, Sunscreens, Lip products
- Environmental note
- Nylon-12 is a microplastic, and while it is not absorbed by the skin, it can enter waterways when rinsed off. Some brands are moving toward biodegradable alternatives.
Good to know
- Nylon-12 is different from Nylon-6 or Nylon-66; it is specifically designed for cosmetic use.
- It is often used in combination with other powders like silica or talc to achieve the desired texture.
