Method Laundry Detergent

Method Laundry Detergent uses a corn and coconut-derived surfactant system that is genuinely better from a sourcing standpoint than petroleum-derived surfactants in conventional detergents. The plant-based surfactants are biodegradable and effective. Method is also highly concentrated — 8× concentration means less packaging per load than standard detergents. These are real improvements over the mainstream laundry products Method positions itself against.

The fragrance situation undercuts the clean formula positioning for most SKUs. Method's laundry line is predominantly fragranced, and the scents are prominent rather than subtle. The fragrance blends are synthetic and proprietary — listed as 'fragrance' with the same lack of compound disclosure as conventional detergents. For a brand that markets ingredient transparency and plant-based chemistry, the fragrance opacity creates a contradiction: the cleaning chemistry is disclosed, the scenting chemistry is not.

Benzisothiazolinone (BIT) has appeared in some Method laundry formulas as a preservative. BIT is a broad-spectrum biocide that is effective at preventing microbial growth in liquid products but is a documented skin sensitizer and is restricted or requiring disclosure in multiple markets. It's not a universal ingredient in Method products, but it's worth checking the current label of specific SKUs if preservative sensitivity is a concern.

Method's free+clear variant removes fragrance and was formulated specifically for sensitive skin applications. It represents Method's ingredients at their best — the plant-based surfactant system without the synthetic fragrance addition. If Method is a preferred brand due to availability, price, or existing household supply, the free+clear version is the appropriate choice. For households building a low-tox laundry setup from scratch, EWG Verified options offer a higher standard of independent ingredient verification.
