Saponis, the soapmaker’s math bench

Field notes

The homepage divides the project into four formulation areas, with the soap bench marked active while anhydrous products, creams, and surfactant cleansers remain in calibration or planning stages. Its stated inputs include 22 fats and butters, dual sodium- and potassium-hydroxide handling, and mold dimensions; its stated outputs include INCI and FDA mass-balance labels. Computation is described as client-side and reactive, with oil libraries and substitution tables exposed as supporting resources.
