Overview
EN 12728:1999 (CEN) defines a standardized laboratory test - the perforated disc beating method - for the determination of the foaming power of surface active agents (surfactants). The method applies to aqueous dilutions with varying degrees of calcium hardness and is intended for samples containing surface active agent ≤ 1 % (m/m). This European Standard provides a reproducible procedure to assess foam generation under controlled conditions so that surfactant foaming behaviour can be compared across products and laboratories.
Key Topics
- Scope and applicability: Test limited to surfactant solutions with concentrations up to 1% (m/m) and to water of different calcium hardness levels.
- Test principle: Use of a perforated disc beating device to generate foam; foaming power is assessed from the foam produced under the specified test conditions.
- Controlled variables: Emphasis on water hardness (calcium content) as a factor that affects foaming, and consistent sample concentration to ensure comparable results.
- Expected content of the standard: As with typical CEN test methods, the standard will specify apparatus, reagents, sample preparation, test procedure, and presentation of results to support reproducibility and comparability.
- Result expression: Foaming power is expressed in a standardized way so laboratories can report and compare outcomes (method details are in the standard text).
Applications
- Quality control: Routine QC testing of detergents, household cleaners, shampoos and other formulated products where foam performance is important.
- Product development and R&D: Comparing foaming characteristics of surfactant candidates and optimizing formulations with respect to water hardness.
- Comparative testing: Benchmarking competing surfactants or formulations under controlled hardness conditions.
- Regulatory and specification compliance: Providing standardized data to support product specifications, claims, or regulatory dossiers.
- Testing laboratories: Analytical and contract test labs use the method to produce comparable foaming data for clients.
Who should use EN 12728
- Surfactant and detergent manufacturers
- Personal-care formulators
- QC and analytical laboratories
- Research institutions studying foam behavior
- Standards bodies and procurement teams specifying foaming tests
