  • the negative charge alkoxylated polyarylphenol increased the L* of the monitors. High L* values equate to a cleaner whiter fabrics.
  • the negative charge alkoxylated polyarylphenol provides significantly better benefits than the ethoxylated polyethyleneimine.
  • the formulation was used to wash eight 5x5cm knitted cotton cloth pieces in a tergotometer set at 200rpm. A one hour wash was conducted in 800ml of 26° French Hard water at 20°C, with 2.3g/L of the formulation. To simulate particulate soil 0.04g/L of 100% compressed carbon black (ex Sigma-Aldrich) was added to the wash liquor. To simulate oily soil (6.3 g) of an SBL2004 soil strip (ex Warwick Equest) was added to the wash liquor.
  • Formulations were tested containing TAMOL ® NN7718 (BASF), the polycondensate product of naphthalene sulfonic acid and formaldehyde, and lignin sulphonate as comparison sulphonated aromatic polymers for anti-redeposition benefits.
  • Formulation were tested containing a negative charge Alkoxylated polyarylphenol, Dispersogen LFH ex Clariant, (tristyrylphenol polyoxy ethylene phosphoric acid ester (anionic)).
