Did you know that bacteria can grow in your detergent? Preservatives, however, protect it from this.
In liquid products, preservatives ensure that the formulations remain stable. Without preservatives, products can start to smell unpleasant or bacteria can grow. Preservatives that are added to detergents and cleaning products, regardless of their concentration, are indicated on the packaging in accordance with the EU Detergents Regulation. People with a known allergy should thus be able to avoid products containing the substance when making their purchase decision.
We use preservatives very carefully and only as much as necessary. Thus, we try to avoid preservatives as far as possible when preservation can be achieved by other formula components. During application the product is generally diluted with a lot of water.
