What Method Dish Soap, Frosted Fir is made of, ingredients and materials
Method Frosted Fir is a water-based liquid soap concentrate formulated from surfactants, water, and botanical fragrance compounds. Unlike bar soaps or solid detergents, liquid concentrates eliminate concerns about mineral coatings or ceramic residue transfer. The water base means no volatile organic solvents are present in the formulation itself, and no Teflon-type coating or synthetic polymer coatings are involved in the product as sold.
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 (synthetic and botanical)
Frosted Fir fragrance is a complex blend not itemized on the label. Synthetic fragrance compounds and some botanical essential oils (e.g., limonene, linalool) are known sensitizers; risk varies by individual exposure history and skin barrier integrity.
Skin irritation from surfactant concentration
Concentrated liquid soaps require dilution to avoid skin contact sensitivity. Undiluted or excessive use can cause irritation, redness, or dermatitis; this is a use-error hazard, not a formulation defect.
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 (fragrance contaminant)
No recalls or published test results link Method liquid soaps to 1,4-dioxane contamination. Risk is theoretically present in surfactant ethoxylation byproducts but is not on record for this brand.
Formaldehyde / VOCs
Method has a stated preference for alternative preservative systems and does not list formaldehyde releasers in available product literature. No regulatory action or recall has been issued for this product on this basis.
Source, ATSDR ↗Heavy metals
Frosted Fir is a cosmetic-grade liquid with minimal pigmentation; no cadmium, lead, or chromium contamination is on record. The 'frosted' descriptor likely refers to opacity from surfactant suspension, not inorganic colorant load.

The brand's record and disclosure
Method has a documented commitment to sustainable and transparent formulation practices, with third-party certifications including EPA Safer Choice recognition for several products. The brand does not publicly claim PFAS-free status but has not faced major recalls or regulatory action for this product line. Fragrance ingredients are not individually disclosed on the label, which is standard industry practice but limits consumer verification of specific allergens.
How it compares in its category
Liquid soap concentrates like Method occupy the lower-hazard end of cleaning products because they avoid the coating durability and leaching concerns of solid block soaps and the volatile off-gassing risks of powdered or aerosol cleaners. Method's positioning as a plant-derived, phosphate-free formula is consistent with mainstream 'green' brands; it carries no known additional restrictions versus unscented or fragrance-free alternatives in the same category.
If you buy it
Use as directed; dilute concentrate with water according to package instructions to minimize skin contact during application. Store in a cool, dark place away from direct sunlight to preserve fragrance stability and prevent degradation of surfactant activity. No special disposal or recycling protocol is required beyond rinsing the bottle; it is water-soluble and compatible with municipal wastewater treatment. Discontinue use if skin irritation or respiratory sensitivity to fragrance occurs, particularly for individuals with fragrance allergies or asthma.
