The Cosmetics Lab Soap Calculator: what's new

(version: 1.0.2025.259)

We've added new features in our Soap Calculator. Here's what's new:

"Pinned" action buttons – Key actions (Back, Next, Save, Print) are always available in a fixed bottom panel. No need to scroll when moving between the recipe and results pages — a big plus for mobile users.
"Save" button always available – You don't have to go to the results page to save a recipe.

Expandable recipes in your recipe list – You can now expand or collapse recipes directly in the management page to see recipe details at a glance.
Filters (by recipe name and ingredients) make it much easier to find exactly what you’re looking for.
We’ve prepared a new video to demonstrate the features of the updated recipe management page. You can watch it here.

A neater, more compact layout for selected oils and ingredients reduces scrolling when making selections.
Selected oils can be sorted alphabetically, by quantity, or in a custom order (via drag-and-drop).
Selected additives can be sorted alphabetically, by stage (then alphabetically), or in a custom order (via drag-and-drop).
In the results view, when additives are sorted by stage (then alphabetically), they are grouped and arranged to clearly show when each should be added during the process.
Additives can be filtered by type for faster selection.
A "Clear search" button makes it quicker to search through oils and additives lists.
Oil information (soap properties and fatty acids) is now accessible by clicking the "i" icon next to each oil.
Automatic conversion between weights and percentages when switching measurement methods.
