Ingredient review
Laminated Polyethylene Powder
INCI: POLYETHYLENE/POLYETHYLENE TEREPHTHALATE LAMINATED POWDER
A synthetic laminated powder that provides gentle exfoliation but raises environmental concerns due to microplastic content.
In plain English
This ingredient is a tiny, flat particle made by bonding two types of plastic (polyethylene and polyethylene terephthalate). In skincare, it's used to give products a silky feel or to gently scrub away dead skin cells. Think of it like very fine, smooth sand that helps polish your skin. However, because it's a plastic that doesn't break down easily, it can contribute to microplastic pollution when washed down the drain.

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
Laminated Polyethylene Powder 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 Laminated Polyethylene Powder.
- 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 composite material where a thin layer of polyethylene is laminated onto a polyethylene terephthalate base, then ground into a fine powder. It is designed to be a uniform, non-absorbent particle for cosmetic texture and exfoliation.
How it works
In a formula, these tiny laminated particles create a physical scrubbing action when massaged onto the skin, helping to dislodge dead skin cells and debris. They also add a smooth, silky feel to products like primers or masks because of their flat, plate-like shape.
Pros
Consistent exfoliation
The laminated structure creates uniform particles that provide a predictable, gentle scrubbing action without the jagged edges of some natural exfoliants.
Smooth texture
In makeup or masks, it adds a silky, non-greasy feel that helps products glide on and feel lightweight on the skin.
Cons and cautions
Environmental microplastic concern
As a non-biodegradable plastic, this ingredient can persist in waterways and contribute to microplastic pollution after being washed off.
Potential skin irritation
If the powder is too coarse or used with heavy pressure, it can cause micro-tears or irritation, especially on sensitive skin.
Best for
- People looking for a gentle physical exfoliant
- Those who prefer synthetic ingredients for consistency
Use caution if
- Individuals with very sensitive or broken skin
- Environmentally conscious consumers avoiding microplastics
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations, but its environmental impact is a significant concern. Skin irritation is possible with overuse or on sensitive skin.
Research notes
Limited peer-reviewed research on this specific laminated composite. General studies on polyethylene microplastics indicate low acute toxicity but raise environmental persistence concerns. Most safety data comes from industry assessments.
Common label clues
- Typical concentration
- Typically 0.5–5% in rinse-off products
- Regulatory status
- Generally allowed in cosmetics globally, but some countries (e.g., UK, Canada) are restricting or banning plastic microbeads in rinse-off products. Check local regulations.
- Common uses
- Exfoliating scrubs, Peel-off masks, Makeup primers
- Environmental note
- This ingredient is a microplastic and does not biodegrade. It can accumulate in oceans and soil, potentially harming wildlife. Many brands are phasing it out in favor of biodegradable alternatives.
Good to know
- This ingredient is often listed under broader microplastic bans in some regions
- It is different from pure polyethylene powder, which is softer and used as a filler
