Work out surfactant active percentage instantly with clear inputs, formula shown and shareable results.
Surfactant raw materials are supplied as solutions — sodium laureth sulphate is typically 70% active, cocamidopropyl betaine 30%. Formulating on active content rather than as-supplied weight is essential, otherwise switching between suppliers with different actives silently changes the product.
Active content
Active mass = raw material x raw active %; active in product % = active mass x 100 / batch size
Raw material needed
Raw material = batch x target active % / raw active %
Because cleaning power, foam and viscosity depend on active surfactant concentration. Two 30% dosages of raw materials at 30% and 70% active give completely different products.
Yes. It must be deducted from the added water in the formula, or the total will exceed 100% and the actual concentration of everything will be wrong.
