This guide also includes recommendations regarding packaging material. By requiring that their suppliers follow these guidelines, and th

Import of the mentioned products from, in particular, developing countries to the European Union (EU is also facilitated and promoted by t

Please note that when limit values are given, possible contamination by t

9、he external environment and inaccuracy in the measurement of very low concentration must be taken into consideration.Recommended substitutes are less harmful while providing the desired effect or property.EXPLANATORY SECTIONWord listLimit value:Limit value as agreed in business sector and or by lega

10、l requirements.Note that the limit value is measured in products. Weight percentshall be calculated from the weight of the whole product if nothingelse is stated.CAS RN: Chemical abstract services registration number.CAS RN are given for specific defined substances.Properties:Human toxicological and

Test equipment if nostandardized test method exists. Abbreviations of recommended testequipment are explained below.De

12、tection limit:Lowest concentration the test equipment is able to detect. This canvary between different test laboratories. Note that detection limit isnot relevant as required limit values for all substances as thebackground concentrations can be notably higherPackaging material: According to Direct

13、ive (EC No 94/62/EC of 20 December 1994 onpackaging and packaging waste. The directive regulates substances inpackaging material; meaning all products made of any materials ofany nature to be used for the containment, protection, handling,delivery and presentation of goods, from raw materials to pro

A general division into four categories has therefore been made.TextileTextile material, both natural and synthetic fibres LeatherLeather, bothnatural andleather imitationAccessoriesMetal, plasticsetc. used in

20、inished product. Remains of the process chemicals may however be found in the finished product and cause health or environmental problems.Alkylphenol ethoxylates (APEO and derivatives The most common APEOs are Nonylphenol ethoxylates (NPEO and Octylphenol ethoxylates (OPEO.Limit value:Should not be

21、used in processes. Occurrence in products below100 mg/kg (0.01% for total APEO is regarded as unintendedresidues (contaminants which cannot be controlled. Properties:Irritating to skin. The metabolites affect the respiratory system,have endocrine disruptive effect (hormones and are dangerousfor the

22、environment. Nonylphenol ethoxylates are rapidlydegraded to 4-nonylphenol, which is even more dangerous forthe environment. A similar environmental danger is thedegradation of octylphenol ethoxylate into 4-octylphenol. Use:Dispersing and emulsifying agents in textile chemicals as wellas impregnation

23、 agents in printing pastes. Occurs in leatherlubricants. Manufacturing of coatings.Comments: The main alternatives for NPEs also include alcohol ethoxylates,both linear and branched, and glucose-based carbohydratederivatives such as alkylpolyglucoside, glucamides, andglucamine oxides.Legal backgroun
