Goat Milk Soap Recipe Calculator
Recipe Breakdown
Tip: Always use a digital scale for accuracy. Safety first—wear gloves and goggles when handling lye.
How to Use This Tool
Enter your desired batch size in ounces, select your main oil type, choose the lye type, set a superfat percentage (for extra moisturizing), and specify any fragrance amount. Click 'Calculate Recipe' to see a detailed breakdown of ingredients. Use 'Reset' to clear all fields.
Formula and Logic
The calculator uses saponification values (SAP) for different oils to determine lye required. Total oils are estimated as 80% of batch size. Lye amount is adjusted by superfat percentage to leave unsaponified oils for skin benefits. Goat milk and water are proportionally calculated based on oil weight.
Practical Notes
- For a standard bar, aim for 4-5 oz per bar; adjust batch size accordingly.
- Use cold process method for best results with goat milk.
- Freeze goat milk before mixing with lye to prevent scorching.
- Cost consideration: Olive oil is economical; coconut oil adds hardness.
- Unit conversion: 1 oz ≈ 28.35 grams; scale up for larger batches.

Frequently Asked Questions
Can I use this calculator for melt-and-pour soap?
No, this calculator is designed for cold process soap making, which involves lye. Melt-and-pour bases already contain lye and require different calculations.
What if I want to use a different oil blend?
Select 'Custom Blend' and use an average SAP value. For precise blends, calculate each oil separately and sum the lye requirements.
How do I adjust for fragrance sensitivity?
Reduce the fragrance amount or use essential oils instead. Always perform a patch test before full use.
