Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want an affordable, fragrance-free, simple powder for everyday loads.
You value the fragrance-free, brightener-free, preservative-free profile and are comfortable with a disclosed ethoxylated surfactant.
You prefer powder for reduced packaging and no preservative concerns.
You want named enzyme cleaning power in a liquid concentrate without compromising on fragrance-free, non-ethoxylated ingredients.
Liquid convenience matters — this delivers the clean formula profile without the powder-format tradeoffs.
Value is a factor — at $38/load this is competitive with mainstream brands for a substantially cleaner formula.
The main thing to know
The one real flag is the surfactant. Linear Alcohol Ethoxylate is effective and fully disclosed, but ethoxylated surfactants can carry trace 1,4-dioxane, and Nellie's has not published a test ruling it out. If a verified dioxane-free formula matters to you, a mineral-base powder is the safer pick.
The preservative system (phenoxyethanol-based) is the only meaningful gap versus the top-tier powder formats. Not high-hazard, but if zero preservatives is a hard requirement, a dry-format sibling is a better fit.
Skip this if you...
You specifically want a lab-verified 1,4-dioxane-free formula.
You regularly tackle heavy protein or grease stains without pre-treating.
Independent third-party certification is a requirement before you buy.
Zero preservatives is a hard requirement — Molly's Suds Powder is a better fit.
Independent third-party ingredient certification is required before purchase.
You prefer dry formats for reduced packaging and shipping footprint.
