Hard Water Tolerance of Mixed Surfactant Systems Containing Sodium Dodecyl Sulfate and Decyl Polyglucoside
J. Environ. Nanotechnol., Volume 8, No 4 (2019) pp. 23-25
Abstract
The objective of this research was to evaluate the efficiency of the mixed micelles of glucoside-sodium dodecyl sulfate surfactant for estimation of water hardness. The non-ionic glucoside surfactants have proved themselves as potential alternatives to the cleaning and washing commodity market, exhibiting effective hard water tolerance. The suitability of the glucoside surfactant for the lime soap dispersion ability was determined through the mixed micellization studies. The effect of incorporation of synthesized decyl polyglucoside to the anionic sodium dodecyl sulphate surfactant on the water hardness tolerance has been investigated through nephelometric measurements. No turbidity was observed up to 350 ppm hardness of water beyond 10% level of incorporation of APG10. The plots of turbidity against water hardness for 1:0, 4:1, 2:1 and 1:1 calcium to magnesium ratio have revealed a linear variation of turbidity with hardness for a fixed surfactant concentration at 2.5 mM. In comparison, decyl polyglucoside was found to be better in hard water tolerance than anionic surfactants. Hence, it was concluded that with moderate foaming, decyl glucoside would be a better surfactant for making detergents to face water crisis.
