Formulation Intelligence

Formula Builder

A guided wizard that adapts to your product. Butters, water phase and essential oils are all optional — skip anything you don't want to use, then take your finished recipe to the calculator for batch sizing in grams.

Pick your product

Each preset is a balanced starting point — the wizard will let you customize ingredients before generating the final recipe.

African Black Soap (ABS)

A traditional alkaline cleanser made from plant ash and oils. It clarifies strongly, so hair and facial formulas must be diluted and pH-checked carefully.

Syndet (soap-free cleansing bar)

Short for synthetic detergent: a soap-free cleanser made with surfactants. It can be mild and pH-balanced; synthetic does not automatically mean harsh.
