The 60-Second Bathroom Microplastic Audit: 12 Products to Scan First (2026)

Last updated: June 21, 2026

Why a 60-second audit beats trying to research everything

The microplastic ingredient list across modern personal-care products is genuinely overwhelming. The average shampoo ingredient list has 25–40 items; mainstream toothpastes have 15–25; sunscreens 20–30. Researching each one individually, cross-referencing with the EWG database or PubChem, and tracking which products contain which ingredients is a project, not a decision.

The 60-second audit reframes the problem: you scan once per product, get a 0–100 score, and act on the worst few. Most users discover that 3–5 products account for 70-80% of their daily plastic-ingredient exposure. Replacing those 3–5 cuts the load disproportionately. The remaining products are either already-clean or low-frequency-use.

The 12 products in priority order

1. Sunscreen

Most-likely-plastic-ingredient: dimethicone, acrylates copolymer, polyethylene. Highest priority because you apply 1+ ounce per use to your largest organ (skin), often in summer when daily reapplication compounds exposure. See our best sunscreens without microplastics for cleaner picks. Scan first.

2. Deodorant

Most-likely-plastic-ingredient: PEG, dimethicone, propylene glycol, acrylates copolymer. Daily use on thin axillary skin near lymph nodes makes this a high-exposure category. Almost every mainstream antiperspirant has 3-4 plastic-flag ingredients. See our deodorant brand ranking. Scan second.

3. Shampoo

Most-likely-plastic-ingredient: polyethylene (exfoliating shampoos), dimethicone (smoothing shampoos), PEG, acrylates copolymer. You use a quarter-sized amount 2-4× per week — meaningful accumulated load. Plus the production-scale plastic ingredients wash directly into waterways. See microplastics in shampoo & conditioner.

4. Conditioner

Most-likely-plastic-ingredient: dimethicone, amodimethicone, behentrimonium chloride, cyclopentasiloxane. The smoothing/detangling function of modern conditioners is achieved almost entirely with silicones — a cluster of related liquid plastics. “Silicone-free” conditioners (Verb, Briogeo, Innersense) are the cleaner picks.

5. Body wash

Most-likely-plastic-ingredient: sodium polyacrylate (thickener), PEG-7 olivate, acrylates crosspolymer, polyquaternium-7. Body washes apply more product per use than shampoo — and the surfactants strip the skin's natural lipid barrier before the plastic ingredients have a chance to interact with skin. Bar soap is the cleanest alternative; Dr. Bronner's Castile is the simplest clean option.

6. Body lotion

Most-likely-plastic-ingredient: dimethicone, carbomer, PEG-40 stearate, cyclopentasiloxane, polyacrylate-13. Lotion stays on skin and is absorbed over hours. Daily-use body lotions in winter or year-round-dry-skin contexts deliver meaningful cumulative load.

7. Hand soap

Most-likely-plastic-ingredient: PEG-150 distearate, polyquaternium-7, polyacrylate, acrylates copolymer. Frequency of use is the issue — most adults wash hands 6-15× per day. Bar soap (Dr. Bronner's, Kirk's) is the cleanest format. Refillable foam dispensers with simple liquid soap are second-best.

8. Toothpaste

Most-likely-plastic-ingredient: polyethylene (exfoliating), PEG-12, carbomer, sodium polyphosphate. You spit out most of it but you also swallow some. Direct mucous-membrane contact for 2 minutes 2× per day is non-trivial. See best microplastic-free toothpaste.

9. Mouthwash

Most-likely-plastic-ingredient: poloxamer 407, polysorbate 80, PEG-40. Direct mouth contact for 30–60 seconds, then partial swallow. Major brands (Listerine, Scope) all contain at least one polymer; alcohol-free natural versions (Tom's of Maine, Tend mouthwash) are cleaner.

10. Face moisturiser

Most-likely-plastic-ingredient: dimethicone, carbomer, acrylates/C10-30 alkyl acrylate crosspolymer, PEG variants. Direct face application with daily reapplication. High-end face moisturisers are often worse than mid-tier because the “luxurious feel” is silicone-based. Simple options: Cetaphil Daily Hydrating Lotion (basic), Pipette Baby Lotion (clean), Weleda Skin Food.

11. Hand sanitiser

Most-likely-plastic-ingredient: carbomer, PEG-12 dimethicone, propylene glycol, polyacrylate. The gel texture of standard hand sanitiser is achieved with carbomer. Liquid alcohol-only formulations (PurellAdvanced Liquid, Touchland Power Mist) often have shorter ingredient lists than the gels.

12. Lip balm

Most-likely-plastic-ingredient: polybutene, polyethylene, microcrystalline wax (petroleum derivative). You ingest small amounts of lip balm with normal use. Beeswax-based balms (Burt's Bees Original, Badger Cocoa Butter Lip Balm) and pure plant-oil balms (Hurraw!) are the cleanest picks. See microplastics in lipstick & lip balm.

The 5 ingredients to flag on every label

The actual 60-second audit workflow

1. Open the MicroPlastics app on your phone, walk to the bathroom.
2. Pick up product #1 (sunscreen).
3. Tap scan, point camera at barcode. Wait ~2 seconds.
4. Read the 0–100 score. If >60, tap the “cleaner alternative” suggestion to see the same-format, similar-budget swap.
5. Move to product #2 (deodorant). Repeat.
6. Continue through the 12 products. Total time: ~60 seconds per product = 12 minutes for the full audit.
7. At the end you have a ranked list of every product in your bathroom by microplastic risk score.
8. Make a list of the 3-5 worst scoring products. These are your replacement priorities for the next time you'd normally repurchase them.

What the data usually shows

In our user audits, the typical bathroom breakdown looks like:

• 3–5 products score above 70 (high-risk — replace next time).
• 4–6 products score 40-70 (medium-risk — swap on next repurchase when convenient).
• 2–4 products score below 40 (clean — no action needed).

The 3–5 high-risk items are almost always: a chemical sunscreen, an antiperspirant, a smoothing conditioner, a thick face moisturiser, and either a hand soap or body wash. Swapping those 3–5 produces measurable urinary phthalate and BPA reductions within 2-3 weeks per the “fresh food and clean product” intervention trials.

What to do with the results

1. Don't throw out perfectly good products. Use what you have until it runs out, then replace with the cleaner alternative. Throwing out unopened products is bad for waste reduction and unnecessarily expensive.
2. Replace in order of use frequency. The product you use daily matters more than the one you use weekly. Replace sunscreen and deodorant first, mouthwash and hand sanitiser later.
3. Buy the cleaner alternative once. Once you've identified the swap (Thinkbaby for sunscreen, Each & Every for deodorant, Briogeo for conditioner, etc.), you don't need to re-research each time. Subscribe or repurchase the same SKU.
4. Re-audit annually. Brand reformulations happen. The Native deodorant you bought last year may be a different formulation today. Quick rescan once a year catches drift.
