Hot Process — Use in 1 Week
Cooked soap that's safe to use in 7 days. Rustic look, full saponification before pour.
Hot process soap is fully saponified in the pot before you pour it. The advantage: bars are usable in 7 days instead of 4 weeks. The trade-off: the pour is thick and rustic-looking, harder to swirl. Great when you need product fast.

Expected qualities
Step-by-step
- Standard procedure to bring to trace in a slow cooker.
- Cook on low. The mass will go through stages: applesauce, mashed potatoes, vaseline, then translucent.
- Total cook time is usually 45–90 minutes depending on cooker.
- Test for zap — when it's gone, the soap is done.
- Add fragrance and any heat-sensitive additives AFTER cook (off-heat).
- Pour into mould — the texture is thick like mashed potato. Pack down firmly.
- Unmould after 12–24 hours. Cut. Bars are safe to use in 7 days but firm up further over weeks.
Notes & troubleshooting
- HP forgives lye-calculation errors slightly because you can see saponification finish.
- Add purées (pumpkin, avocado) AFTER cook; they'd burn during the hot phase.
