SYNTRAN 8441-N

• For color fastness to washing; removal of excess / non-fixed dye after dying / printing. 
• Used in detergents and textile auxiliaries avoids incrustation, greyness of fabrics and keeps fabric fresh in terms of colour, brightness and feel, thereby increasing the life of the fabric.
• Boosts detergency.
• Enhances soil dispersion and prevents its redeposition.
• Excellent temperature and chlorine stability.
• Biodegradable.

SYNTRAN 8442-N

• Used in detergents and textile auxiliaries avoids incrustation, greyness of fabrics and keeps fabric fresh in terms of colour, brightness.

B. Sequestrants

SYNTRAN® polycarboxylates as sequestrants (chelating agents) for usage during scouring, dyeing, printing and other textile treatment processes.

By formation of a water-soluble complex with metal ions (Mg2+, Ca2+), these ions are prevented from impairing the solubility of anionic (hydroyzed reactive) dyes.

Polycarboxylates do not attach metal complex dyes.  They therefore have no ill effect on the shade or fastness of dyeings.
