What Method Dish Soap, Cucumber is made of, ingredients and materials
Method Dish Soap Cucumber is formulated with surfactants derived from plant sources, water, and botanical cleaning agents rather than petroleum-based detergents. Plant-derived surfactants (often coconut or corn-based) break down grease by surrounding oil molecules, making them water-soluble. The brand avoids chlorine, phosphates, and synthetic dyes in this line. Liquid soap formulas carry fewer coating-degradation and leaching risks than concentrated powders or solid tablets, since they do not require water-soluble films or binding agents.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Fragrance allergens and skin sensitization
Method lists 'naturally derived fragrance' without full ingredient breakdown. Plant-derived fragrance compounds (e.g., limonene from citrus) are established allergens; risk is low in rinse-off products but present for individuals with contact dermatitis or citrus sensitivity.
Residual surfactant on dishes after rinsing
All dish soaps leave trace surfactant residue if rinsing is inadequate. Plant-based surfactants are generally biodegradable and lower toxicity than synthetic alternatives, but ingestion of undiluted or heavily residued soap carries mild gastrointestinal irritation risk; standard rinsing practices mitigate this significantly.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
1,4-dioxane contamination
No regulatory or third-party testing data specific to this product on record. Plant-based surfactants have lower inherent dioxane risk than ethoxylated synthetic surfactants, but manufacturing trace contamination is possible in any plant-derived ethoxylated ingredient; Method does not publish testing for this contaminant.
Bottle material leaching
Method Dish Soap is packaged in recycled plastic (typically HDPE or PET). No public recalls or testing data indicate BPA, BPS, or phthalate leaching from the packaging into the soap itself; the acidic and surfactant environment may slightly increase leaching potential, but no specific evidence for this product is on record.
How is this PFAS grade calculated?
The brand's record and disclosure
Method is a certified B Corporation that publishes ingredient transparency on its website and has not faced major recalls or safety litigation related to dish soap. The brand does not make explicit PFAS-free claims and does not publish third-party testing for PFAS in this product; however, no regulatory findings of PFAS contamination in Method liquid soaps are on public record. Method has faced scrutiny in the past over fragrance disclosure (allergens), but the Cucumber variant lists fragrance ingredients as 'fragrance (naturally derived)' without full component transparency, which is industry standard.
How it compares in its category
Method Dish Soap sits in the premium plant-based segment, positioned similarly to Seventh Generation and Ecos. Most conventional dish soaps (Dawn, Palmolive) contain synthetic surfactants and dyes, which carry no higher chemical risk but differ in environmental profile. Plant-based formulas reduce concerns around persistent synthetic residues on dishes, though all dish soaps rinse substantially in normal use. Method's price is higher than mass-market alternatives but comparable to other plant-certified brands.
If you buy it
Store at room temperature away from extreme heat; liquid soaps remain stable and do not separate significantly over 1-2 years of typical home use. Use as directed (small amount per wash); overuse does not improve cleaning and increases residue risk on dishes if rinsed inadequately. No special precautions needed for skin contact during normal dishwashing; rinse hands and dishes thoroughly. Discontinue use if skin irritation occurs, particularly if you have known sensitivity to botanicals or fragrance compounds.
