Any preservative agent added to the product will also be indicated on the label. Very small quantities of preservatives are present in many detergents to ensure that the product lasts a long time and it keeps its quality over time.
The INCI name
Each ingredient, whether a fragrance or a preservative, is listed with its internationally recognized name – the INCI name (International Nomenclature of Cosmetic Ingredients). By giving each ingredient a unique name, it becomes easy for consumers worldwide to recognize the ingredients present, irrespective of language differences.
