Frequently Asked Questions
Common questions about soap making calculations and our tools.
How accurate are your lye calculations?
Our calculations are based on verified SAP values from multiple sources and are accurate to within 0.1%. We use industry-standard saponification values that have been tested and verified by professional soap makers worldwide.
What superfat percentage should I use?
For bar soaps, we recommend 5-8% superfat for optimal conditioning and safety. For liquid soaps, use 0-3% superfat. Higher superfat percentages provide more moisturizing properties but may reduce lather and shelf life.
Can I substitute oils in existing recipes?
Oil substitutions require recalculating lye amounts as each oil has different SAP values. Use our lye calculator to adjust amounts when substituting oils, and consider how property changes will affect your final soap.
Is it safe to make soap at home?
Yes, soap making is safe when proper safety precautions are followed. Always wear protective equipment, work in ventilated areas, and use accurate measurements. Our calculators help ensure safe lye-to-oil ratios.
