About
soapformulator.com is the formulation platform for soap and skincare makers. Exact, explained, and yours.
Three promises
The most trusted free lye calculator on the web. Every number explained, every oil value cited to a published range and a named source, no login, no ads on the calculator, fast on a phone with wet hands.
A formulator's workbench, not a recipe locker. Here now: saved recipes with versions, a batch log with cure tracking, fragrance and allergen checks, cost per bar, labels, stock, lot tracing, batch records, finished goods, a safety dossier for the assessor. Priced by capability, never by row count.
Every product a soaper actually makes. Bar, liquid, cream and shave soap, and syndet bars, lotions, bath bombs, lip balm, candles and melt and pour, on the same engine.
Two pledges
Portability. Your recipes are yours: import from anywhere, export everything, in open formats, free, forever.
Import a recipeBilling you can trust. You always see what you have and what you paid, you can refund a first payment yourself within 30 days, and nothing you saved is held back if you stop paying.
RefundsOpen by design
The ingredient database is licensed ODbL and built only from primary documents. The formula library is MIT. If you run a blog, a supply shop or another tool, you may use both, with attribution.

What this is notNot a safety assessment, not a regulatory filing, and not a substitute for weighing your lye on a good scale. Verify any recipe you did not calculate yourself, and treat compliance documents produced here as drafts for your assessor.
Your recipes, batches and labels in one place.
Saving a recipe works without an account. An account keeps them in one list, beside your batch log.
