Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You mainly want strong enzyme cleaning power in a concentrated low-suds liquid for everyday loads.
You are not personally sensitive to preservatives, optical brighteners, or fragrance.
You prefer a 4X concentrate for lighter packaging and easy single-capful dosing.
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 real problem is the preservative system. This Free + Clear formula contains methylisothiazolinone and benzisothiazolinone, both strong skin sensitizers, alongside an optical brightener and an undisclosed fragrance. Despite the plant-based, B Corp marketing, the ingredient panel does not match a clean positioning, and that is why it scores at the bottom of the category.
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 have eczema, sensitive skin, or are washing for a baby, where the methylisothiazolinone preservative is a poor fit.
You want a genuinely fragrance-free and brightener-free formula rather than one marketed that way.
You want a verified clean detergent with EPA Safer Choice certification and a published dioxane test.
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.
