ISO 4319 Surfactants - Comparison Test of Detergents for Fabric Washing

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4319 testing. ISO 4319 is a standard created for comparative testing of fabric washing products to realistically reflect the performance of products likely to be used by consumers.

It details the variables to be considered, shows the importance of each of these variables, and provides a basis for the preparation of adequate comparative test methods to give a valid estimate of the performance of two fabric washing products.

Some of the ISO 4319 requirements are:

• Composition: Detergents should consist of ingredients that are safe and effective for cleaning fabrics.
• Performance: Detergents should have the cleaning power to remove various types of stains and dirt from fabrics.
• Compatibility: Detergents should be compatible with a wide variety of fabrics and should not cause damage or discoloration.
• Safety: Detergents should be safe for the user and the environment and should not contain harmful substances above certain limits.

ISO 4319 also specifies various test methods for evaluating the performance of detergents. These test methods include:

• Stain removal: The detergent's ability to remove standardized stains from fabric,
• Color fastness: The ability of the detergent to preserve the color of the fabric and not fade or bleed,
• Fabric damage: The effect of detergent on the strength and integrity of the fabric,
• Foaming: The amount of foam produced by the detergent that can affect the effectiveness of the washing process.

Compliance with ISO 4319 can ensure that a detergent used for washing fabric meets specified performance, safety and compatibility requirements.
