Emulsifier Dosage Calculator

Work out emulsifier dosage instantly with clear inputs, formula shown and shareable results.

About Emulsifier Dosage Calculator

Emulsifier is normally dosed on the oil phase rather than the total batch, because its job is to cover the interfacial area created when that oil is dispersed. Typical doses are 1-3% on oil for food emulsions and up to 5% for fine emulsions with very small droplets and large interfacial area.

Formula

Emulsifier dose

Oil mass = batch x oil phase %; emulsifier = oil mass x dose on oil %

Worked example

With the default values below, Emulsifier Dosage Calculator returns Emulsifier Required of 3.5000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why dose on oil rather than total?

Interfacial area scales with the oil volume and the inverse of droplet size. Dosing on the total batch means changing the oil content silently changes the coverage.

What determines the dose?

Target droplet size, oil type, emulsifier efficiency and the required stability period. Smaller droplets need proportionally more emulsifier because interfacial area rises as diameter falls.
