Formulation tools

Formulate with precision, not guesswork.

Use practical cosmetic formulation calculators to scale batches, convert percentages to weights, estimate ingredient costs and work out safe usage amounts with confidence.

Note: conversions between weight and volume depend on ingredient density. Water is approximately 1g/ml, but oils, surfactants and powders can vary.

Usage Rate Calculator

Calculate how much of an ingredient to use based on its recommended percentage range. Useful for preservatives, fragrances, essential oils, actives, extracts and colourants.
