¹⁾ Product Class:		I II III IV	baby in direct contact with skin with no direct contact with skin decoration material
²⁾ when used as aftertreating agent to improve the wet fastness of dyeings and prints with acid dyestuffs
³⁾ suitable for product class I, if rinsed well
⁴⁾ COD	=	Chemical Oxygen Demand (mg 0₂/g product)	The COD is a measure of the sum of all organic substances. It indicates the quantity of oxygen required to completely oxidise organic substances.
⁵⁾ BOD₅	=	Biochemical Oxygen Demand (mg 0₂/g product)	The BOD is a measure of the sum of all biodegradable organic substances. The BOD₅ indicates the quantity of dissolved oxygen required to biodegrade organic substances within 5 days. It is one parameter to establish the degradability of a product. However, there are only few substances that are completely biodegraded after 5 days!
COD/BOD ratio			For the practical person in the sewage plant this ratio is a reference value for the biodegradabilty. Based on experimental values it is assumed that a COD/BOD ratio up to 2 is a sign for easily degradable waste water. The higher the ratio, the poorer the degradability.
			Note The COD/BOD relation is often mistakenly taken to evaluate the biological degradation of a chemical product. What must be considered, however, is the COD/BOD₂₈ relation. Since hardly any substances are biodegraded after only 5 days, the biological oxygen demand after 28 days is usually much higher.
