Definitions

  • FIG. 9 schematic illustration of the method of manufacturing a detergent and preparation of detergent in accordance with an embodiment of the invention.
  • Crushed refined soda fines included in the detergent formulation may act as a bicarbonate source so as to control the pH of the detergent formulation at higher range (> pH 9) and to stabilize methyl ester sulphonate, which is prone to degradation at higher pH.
  • generation of hydroxyl ions occurs due to dissolution of alkaline salts in water and these ions may affect the effectiveness of methyl ester sulphonate.
  • the bicarbonate present in the detergent formulation provides a buffering effect.
  • the bicarbonate ions react with hydroxyl ion (generated from salt hydrolysis) to form carbonate ion and water (II). This allows methyl ester sulphonate to be effective even at higher pH levels.
  • the detergent composition as described is suitable for use in both soft and hard water.
  • Such process(s) wherein the dispersing agent is an alpha-sulpho fatty acid, preferably a linear alkyl benzene sulphonic acid.
