Microplastics in Makeup and Skincare: Ingredients to Watch For

Microplastics aren't just a food and water problem. They're also baked into cosmetics, skincare, scrubs, sunscreens, glitter, and personal-care products — usually under ingredient names most shoppers wouldn't recognize as plastic. The EU has restricted intentionally added microplastics in cosmetics from October 2023 onward, but the changeover is slow, varies by category, and US regulations remain looser.
Quick Answer
Quick answer: Common plastic ingredients in cosmetics include polyethylene, polypropylene, nylon-6 / nylon-12, acrylates copolymer, acrylates crosspolymer, carbomer, PEG (any number), dimethicone, and polyurethane. Microbeads (solid plastic particles for exfoliation) are banned in US rinse-off products since 2015 but persist in some imports; liquid microplastic polymers and film-formers remain widely used.
Highest-risk products: rinse-off scrubs and exfoliants with microbeads, glitter cosmetics, “long-wear” foundations and lipsticks (heavy acrylates), liquid eyeliners and mascaras (film-formers), shimmer powders, body washes with PE microbeads.
Best first swap: install the Beat the Microbead app or scan ingredients with our app to filter your current routine. Then prioritize replacing the products with the biggest weekly contact area — face wash, moisturizer, sunscreen, and foundation.
| INCI name | Type | Common in |
|---|---|---|
| Polyethylene (PE) | Solid plastic microbeads | Old exfoliants, scrubs (banned US 2015 in rinse-off) |
| Polypropylene (PP) | Solid plastic particles | Mascaras, eyeshadow primers |
| Nylon-6 / Nylon-12 | Synthetic polymer particles | Loose powders, “blurring” primers, dry shampoos |
| Acrylates copolymer | Liquid microplastic / film former | Long-wear foundations, mascaras, sunscreens |
| Acrylates crosspolymer | Cross-linked acrylate polymer | Gel cleansers, lotions |
| Carbomer / Carbopol | Cross-linked polyacrylic acid | Gel cleansers, serums, hand sanitizers |
| PEG (numbered, e.g., PEG-40) | Petroleum-derived polymer | Most lotions, shampoos, conditioners |
| Dimethicone | Silicone polymer (silicone is a polymer, not strictly “microplastic”) | Most moisturizers, primers, foundations |
| Polyurethane | Synthetic polymer | Long-wear products, nail products |
| PETA (polyethylene terephthalate alginate) glitter | PET particles | Body glitter, highlighters, eyeshadow |
| Methyl methacrylate crosspolymer | Acrylate-based polymer particles | Mattifying primers, foundations |
| Polyquaternium (numbered) | Cationic polymer | Hair products, conditioners |
Key Takeaways
- EU banned intentionally added microplastics in cosmetics starting October 2023, with category-specific rolling deadlines through 2035.
- The US 2015 Microbead-Free Waters Act banned PE/PP microbeads in rinse-off cosmetics, but liquid polymers and leave-on microplastics remain unrestricted.
- The Beat the Microbead app and EWG Skin Deep are the easiest free tools for ingredient screening.
- Leave-on products (foundations, sunscreens, moisturizers) deliver longer skin contact than rinse-off products.
- “Clean beauty” brands vary widely — verify ingredients rather than trusting the marketing label.
- Polymer ingredients in cosmetics are primarily an environmental concern (rinse into wastewater) plus skin absorption of additives — the particle itself usually doesn't cross intact skin.
Why cosmetics use microplastics in the first place
Plastic ingredients do useful things in cosmetic formulations:
- Exfoliation — solid microbeads gently scrub skin (replaced by jojoba beads, salt, sugar, rice powder in clean brands).
- Film-forming — acrylates create a smooth, long-wearing finish on foundation and mascara.
- Thickening / gel structure — carbomer turns watery serums into pleasant gel texture.
- Slip and silkiness — dimethicone (silicone) gives the smooth feel of most modern moisturizers.
- Glitter and shimmer — PET-based glitter is brighter, lighter, and more reflective than mineral alternatives.
- Color suspension — keeps pigments evenly distributed.
Functionally they work. The trade-off: they wash down the drain into wastewater systems (where treatment plants can't catch sub-mm particles), end up in waterways and oceans, and the chemical additives (phthalates as plasticisers, parabens as preservatives) absorb through skin.
Rinse-off vs leave-on — different exposure profiles
| Category | Rinse vs leave-on | Microplastic exposure | Replacement priority |
|---|---|---|---|
| Face wash / body wash with microbeads | Rinse-off | Environmental (water systems); low skin contact | High — easy swap to bead-free or natural exfoliant |
| Foundation / BB / CC cream | Leave-on (long-wear) | All-day skin contact with film-formers + additives | High — daily face exposure |
| Sunscreen | Leave-on; full body in summer | Large surface area; chemical absorption of additives | High — switch to mineral (zinc / titanium) |
| Moisturizer / lotion | Leave-on; daily | Daily face + body contact; PEG + silicone common | High — easy swap |
| Liquid eyeliner / mascara | Leave-on | Small area but daily use; acrylates film | Medium |
| Lipstick / lip balm | Leave-on + ingested | Direct ingestion; ~24 mg/day estimated average | High — easy swap to clean brands |
| Loose powders / dry shampoos | Leave-on / inhaled | Nylon-12 + talc + silica inhaled near face | Medium — switch to silica-only or skip dry shampoo |
| Glitter cosmetics | Leave-on / shed everywhere | PET particles into environment + skin | Medium — switch to biodegradable cellulose glitter |
| Nail polish | Leave-on | Acetate polymers + plasticisers | Medium — “10-free” brands available |
| Hair gel / pomade | Leave-on for the day, then rinse | Polyquaternium + acrylates | Medium |
What the regulations actually say
- US Microbead-Free Waters Act (2015) — banned plastic microbeads (intentionally added solid plastic particles ≤5mm) in rinse-off cosmetics. Took full effect 2018-2019. Does NOT cover leave-on products or liquid polymers.
- EU ECHA microplastic restriction (Oct 2023) — broadest cosmetics microplastic restriction to date. Phases out intentionally added microplastics in cosmetics on a rolling schedule by category: rinse-off cosmetics (Oct 2027), leave-on (Oct 2029), make-up (Oct 2035), nail products (Oct 2035).
- UK — followed US 2018 microbead ban in rinse-off; less restrictive on leave-on.
- Canada — banned plastic microbeads in rinse-off (2018).
Practical implication: the products on US shelves today still commonly contain liquid polymers (acrylates, carbomer, PEG) and leave-on microplastics. The label-reading habit and a scanner are still useful even after the major regulatory changes.
