ANALYSIS OF LAUNDRY DETERGENTS



ANALYSIS OF LAUNDRY DETERGENTS- Powders, Bars/ Cakes and Liquids: 
Detergents are graded on the basis of their active matter, carbonate and poly phosphate content.

POWDERS:
Active matter/ Active detergent (% LAS)
Total Alkalinity (% Na2CO3)
Total salt (% NaCl)
Total phosphates
Bulk density & Tapped density for powders
Reflectance (%)
Moisture (%)
Sieve Analysis
pH

CAKES
Active matter/ Active detergent (% LAS)
Total Alkalinity
Total salt (% NaCl)
Total phosphates
Total fatty matter (TFM) for detergent soap
Moisture (%)
pH
Gritt/ Smoothness

LIQUIDS
Viscosity
Specific gravity
pH

Nearly all detergents are alkaline because nearly all soils and most staining agents are acidic. As a result, an alkaline cleaner performs best at removing these soils because they bring these acids into solution.
