Nylon-6
INCI: NYLON-6
Nylon-6 is a safe synthetic ingredient that improves the feel and wear of makeup and skincare, but it has no active skin benefits.
In plain English
Nylon-6 is a type of plastic powder added to cosmetics to make them feel silky and smooth on your skin. It helps products like foundation and eyeshadow glide on easily and stay in place longer. Think of it as a tiny, invisible helper that improves the texture and performance of your makeup without doing anything active for your skin.

Quick decision guide
Useful, but context matters
Nylon-6 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-6.
- 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-6 is a synthetic polymer derived from caprolactam, processed into fine, spherical particles used in cosmetics for their smooth, silky feel and film-forming properties.
How it works
In a cosmetic product, Nylon-6 particles act as tiny ball bearings that reduce friction, giving a silky, spreadable texture. They also form a thin, flexible film on the skin or hair that helps other ingredients adhere and last longer, improving wear time and water resistance.
Pros
Silky texture
Nylon-6 gives makeup and skincare a luxurious, silky feel that glides on smoothly without being greasy.
Improved wear
It helps makeup stay put longer by forming a flexible film that resists smudging and fading throughout the day.
Cons and cautions
No skin benefits
Nylon-6 is purely a texture enhancer—it doesn't moisturize, soothe, or protect your skin in any active way.
Synthetic and non-biodegradable
As a plastic-based ingredient, it may not align with eco-conscious or natural skincare preferences, and it persists in the environment.
Best for
- Anyone who wants makeup with a silky, smooth application and long-lasting wear
- People with oily skin who appreciate a matte finish
Use caution if
- Those seeking purely natural or biodegradable ingredients
- Individuals with very sensitive skin who prefer minimal synthetic additives
Usage tips
Safety summary
Nylon-6 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, as a synthetic plastic, it may not be ideal for those seeking fully natural or biodegradable products.
Research notes
Research indicates Nylon-6 is non-irritating and non-sensitizing in cosmetic use. Its safety has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which found it safe as used. No significant health concerns have been identified in peer-reviewed studies.
Common label clues
- Typical concentration
- 0.5% to 5% in most formulas
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Powders, Foundations, Eye shadows, Lipsticks, Creams
- Environmental note
- Nylon-6 is a synthetic polymer derived from petroleum, and while it is not classified as a microplastic in all regulations, it is not biodegradable and may contribute to environmental plastic accumulation.
Good to know
- Nylon-6 is different from microplastic beads used in scrubs—it's a fine powder, not a scrub particle.
- It is often used in combination with other powders to balance texture and oil absorption.
