Palm oil-based raw materials - RSPO-certified share

contain no palm oil-based raw materials

The proportion of easily degradable ingredients refers to the proportion of organic ingredients that are defined as “easily biodegradable” according to OECD 301 or Detergent Regulation (EC) No. 648/2004. The value of the phosphorus content refers to elemental phosphorus. Palm oil is an important renewable source for the production of raw materials. The Roundtable on Sustainable Palm Oil (RSPO), founded in 2004, promotes sustainable cultivation methods for palm oil. This results in a certification system and the possibility of declaring raw materials as “RSPO-certified”.
