  How to thicken a dishwashing liquid system

  How to thicken a dishwashing liquid system?

  Here is the formula:

  LABSA 9.4%

  NaOH 1.25%

  CDEA 2.7%

  DMDM 0.2%

  NaCl 0.2%

  Scent 0.1%

  EDTA 0.1%

  Scent 0.1%

  For some reason, the dishwashing liquid I made lacks the viscosity. I even tried to hydrate 0.5% xanthan gum with 3% glycerine, but to no avail. Salt just precipitated at the bottom of the system.

  Please help

  To the same formulation, add around 6-8% SLES. Use sodium chloride to adjust the viscosity then as needed.

  Either:

  A. Add some SLES

  B. Add some extra LABSA+NaOH

  C. Add both A and B
  D. Add some extra salt

  Always add salt dissolved in water (i.e. a 25% salt solution), never in powder form.
  Add salt in small increments, like 0.1% (active NaCl), or better yet, do a salt curve experiment to find out the optimum salt amount.
