Ingredient review
Polyamide-12
INCI: Polyamide-12
Polyamide-12 is a safe, non-irritating synthetic powder that improves product feel and controls shine without clogging pores.
In plain English
Polyamide-12 is a man-made powder, similar to tiny plastic beads, that is added to cosmetics to make them feel silky and smooth on the skin. It also helps absorb excess oil and gives a soft-focus effect, blurring the look of fine lines and pores. Because it is inert (doesn't react with skin), it is considered very safe and non-irritating for most people.

Quick decision guide
Useful, but context matters
Polyamide-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 Polyamide-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.

strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
Polyamide-12 is a synthetic polymer made from laurolactam, a type of nylon. In cosmetics, it is processed into fine, spherical (ball-shaped) particles that are used as a texture modifier and oil absorber.
How it works
In a cosmetic product, Polyamide-12 particles act like tiny ball bearings, rolling over the skin to create a smooth, silky feel. They also absorb sebum (skin oil) and scatter light, which helps reduce the appearance of shine and gives a soft-focus blur effect to imperfections.
Pros
Excellent texture enhancer
Polyamide-12 gives powders and foundations a luxurious, silky feel that glides on smoothly without caking.
Oil control without drying
It absorbs excess sebum effectively, helping to control shine throughout the day without stripping the skin of moisture.
Cons and cautions
Synthetic and non-biodegradable
As a nylon-based plastic, Polyamide-12 is not biodegradable and may contribute to microplastic pollution if it enters waterways.
Not suitable for natural skincare fans
If you prefer plant-based or naturally derived ingredients, this synthetic polymer may not align with your preferences.
Best for
- People with oily or combination skin who want shine control
- Anyone who prefers a silky, lightweight feel in powders and foundations
Use caution if
- Those seeking 100% natural or plastic-free formulations
- Individuals with very dry skin may find it too mattifying
Usage tips
Safety summary
Polyamide-12 is considered very safe for topical use. It is non-irritating, non-sensitizing, and has a low comedogenic rating. The main concern is its environmental persistence as a microplastic.
Research notes
Multiple safety assessments, including those by the Cosmetic Ingredient Review (CIR), have confirmed that Polyamide-12 is safe for use in cosmetics at typical concentrations. No significant human health risks have been identified.
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 concluded it is safe as used.
- Common uses
- Powders, Foundations, Primers, Sunscreens, Lipsticks
- Environmental note
- Polyamide-12 is a synthetic plastic that does not biodegrade quickly. While it is generally considered safe for human use, its environmental impact as a potential microplastic is a growing concern. Some manufacturers are moving toward biodegradable alternatives.
Good to know
- Polyamide-12 is also known as Nylon-12 in some ingredient lists.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel and is widely used in cosmetics globally.
