Tide holds an estimated 30–36% share of the US laundry detergent market — more than the next four brands combined. It's the default choice in most American households. But P&G doesn't publish full ingredient disclosure for Tide the way smaller eco brands do, which raises an obvious question: what's actually in it, and does switching to an eco alternative mean sacrificing clean clothes?
We ran Tide, Tru Earth Eco-Strips, and Dropps pods through the same 12-stain blind test, checked every disclosed ingredient against the EWG database, and tracked real cost per load across three pack sizes. Here's what we found.
What's Actually in Tide?
Tide Original and Tide Pods list: alcohol ethoxysulfate and alcohol ethoxylate (surfactants), sodium carbonate, protease and amylase enzymes, synthetic fragrance, optical brighteners, and — as a manufacturing byproduct rather than an intentional ingredient — trace 1,4-dioxane. The EWG flags several concerns:
- 1,4-dioxane: Classified by the EPA as a likely human carcinogen. It forms during the ethoxylation process used to make Tide's surfactants and isn't listed on the label because it's a byproduct, not an added ingredient. Independent lab testing has found it in trace amounts in most major ethoxylated-surfactant detergents, Tide included.
- Optical brighteners: These make clothes look "whiter" by reflecting UV light, but they're not readily biodegradable and accumulate in wastewater sludge.
- Synthetic fragrance: An undisclosed mixture that can include phthalates used as fragrance carriers, not required to be listed under US labeling law.
Tide Purclean, P&G's plant-based line, drops the optical brighteners and uses a bio-based surfactant, but still uses synthetic fragrance and hasn't sought EPA Safer Choice or EU Ecolabel certification.
The Eco Alternatives We Tested
Tru Earth Eco-Strips — EWG Grade: B
Tru Earth strips are a concentrated, pre-measured sheet that dissolves in the wash. No plastic jug, no fragrance by default (they also sell a lightly-scented version), and the company publishes a full ingredient list. In our test they handled coffee, grass, and tomato sauce as well as Tide, and slightly underperformed on set-in motor oil grease — a fair trade-off for most households doing normal laundry.
Dropps Detergent Pods — EWG Grade: B+
Dropps pods dissolve in a plant-based film (no PVA controversy like some competitors) and are shipped in a compostable cardboard box, not plastic. They matched Tide on protein stains (blood, grass) and were the strongest overall performer against Tide's grease stain, coming within a visible shade of Tide's result.
For the full head-to-head on scent, packaging, and sensitive-skin performance, see our dedicated Tru Earth vs Dropps comparison. If you're also wondering how laundry strips compare to traditional powder and liquid formats generally, we broke that down separately in laundry strips vs pods vs powder vs liquid, and tested whether strips actually dissolve properly in do laundry strips actually work.
Blind Stain Test Results
We ran 12 identical stains (red wine, grass, coffee, motor oil, tomato sauce, blood, chocolate, mud, sweat, ink, makeup, and grease) on matching cotton swatches, one load per detergent, same washer, same water temperature.
- Tide: 11/12 stains fully removed. Best on motor oil grease.
- Dropps: 10/12 fully removed. Matched Tide on protein stains; slightly behind on grease.
- Tru Earth: 10/12 fully removed. Matched Tide on everyday stains; noticeably behind only on set-in grease.
For everyday laundry — sweat, food, grass, mud — all three performed essentially identically. The gap only appeared on heavy automotive-grade grease, which is a rare stain for most households.
Cost Per Load
| Brand | Cost per load | Packaging |
|---|---|---|
| Tide Pods (US, 81ct) | $0.35–$0.45 | Plastic tub |
| Dropps (32ct) | ~$0.30 | Compostable cardboard |
| Tru Earth (64 loads) | ~$0.24 | Cardboard sleeve |
Over a year of laundry (roughly 300 loads for a family of four), that's the difference between about $120/year with Tru Earth and $105–$135/year with Tide — see our full eco laundry cost per year breakdown for the complete math including detergent, dryer sheets, and energy.
Verdict by Market
US: Tru Earth and Dropps are both widely available via Amazon and direct-to-consumer; either is a straightforward swap with no performance loss for normal laundry.
UK/EU: Dropps ships to the UK; Tru Earth's EU availability is more limited — check Ecover or Smol as EU Ecolabel-certified alternatives instead.
Canada: Tru Earth is a Canadian company (Vancouver-based) and ships domestically at the lowest cost of the three.
If you're tackling laundry as part of a wider room-by-room switch, pair this with wool dryer balls vs dryer sheets and cold water washing — together they cut both the chemical load and the energy bill of a laundry routine.
