Soap Making
Intelligent soap formulation for every method.
Lye calculations, soap property analysis, mould scaling, INCI labels, and batch tracking — all in one connected workspace.
More than a soap calculator.
Whether you make cold process bars, hot process, or liquid soap, Stillroom HQ handles the maths so you can focus on the craft. Every batch tracked, every recipe stored, every label generated — from your workbench to your customer.
Real Recipe Cards, Not A Mock-Up
What's inside the Soap Making Studio.
Intelligent Lye Calculator
Calculate NaOH and KOH amounts automatically for cold process, hot process, and liquid soap. Set your water ratio and superfat with precision.
Soap Property Analysis
Monitor hardness, cleansing, conditioning, bubbly lather, and creamy lather bars with live visual feedback as you adjust your recipe.
Mould & Batch Scaling
Scale recipes automatically based on mould size, batch weight, or number of bars. No manual maths required.
Fragrance & Additive Guidance
Track fragrance usage rates, acceleration risks, and discolouration notes directly inside your formulations.
INCI Label Generation
Generate compliant ingredient declarations automatically from your recipe data — ready to paste into your label design.
Inventory & Cost Tracking
Connect oils, additives, packaging, and suppliers directly to formulations and production runs for accurate cost-per-bar.
Built For Real Soapmaking Workflows
From first recipe through to finished bars on a shelf.
Designed for teaching and workshops too.
