Recipe Tuner™: create balanced formulas in seconds
The new Recipe Tuner™ lets you adjust your oil blend without editing numbers by hand, by getting a live Soap properties view (hardness, conditioning, lather, and more).
How it works:
- Move any slider to change an oil’s percentage; the others rebalance so the total stays at 100%, and the soap property graph/bars update as you go.
- Move the sliders and watch how the soap properties are affected.
- Once you're satisfied with the soap properties, click Apply to update your recipe, or Cancel to leave it unchanged.

A short 2-minute video tutorial shows how to use Recipe Tuner™. Watch it here.
