CIP Solution Concentration Calculator

Calculate a dilution using stock and target concentrations expressed as % by mass (% w/w). Both must refer to the same active substance or formulated product.

Inputs

Illustrative inputs (not cleaning recipes): Caustic example 1.5% w/w Nitric example 1.0% w/w Sanitiser example 200 ppm w/w

Chemical

Stock concentration (% w/w)

Use the supplier’s verified concentration and chemical identity.

Target concentration (% w/w)

Use the validated recipe and supplier basis; 200 ppm by mass = 0.020% w/w.

Final batch quantity

Choose kg or litres below. A 1,000 kg batch is not a 1,000 L batch.

Quantity basis

Stock density (kg/L)

Example only for 50% NaOH. Use supplier data at the dosing temperature; blank omits stock litres.

Final solution density (kg/L)

Use the density of the final concentration at the specified temperature.

Enter inputs to calculate.

Handling: Follow the chemical supplier’s mixing instructions and the site risk assessment. Use controlled dosing into water where specified; dilution can release heat. Never mix acid and chlorine products. Confirm the finished concentration using a suitable validated analytical method.
