Affiliate disclosure

LyeCal is free to use and reader‑supported. Some links on this site are affiliate links, including links to products on Amazon.

As an Amazon Associate, LyeCal earns from qualifying purchases. If you buy soap‑making supplies through one of our links, we may earn a small commission — at no extra cost to you. This helps keep the calculator free and never changes the price you pay.

Affiliate relationships never influence our SAP values, soap‑quality figures, or guidance. Saponification data and quality predictions are provided as estimates for educational use — always verify critical recipes against a second source and follow proper lye‑safety precautions.
