Hi All

I made liquid laundry detergent it work properly but some time  more viscous liquid will down in the bottom of bottle and less viscouse is in the top ,after shaking it will recover,the problem is that why the down .i need it will make more homogeneous and more transparent?  formula in % is given below
LABSA=15.2%
NaoH=2%
SLES=4%
sodium citirate=3%
EDTA=.2
Nacl=1%
water

    @noorahfm you need to decrease the level of Labsa and increase the level of SLES.

    Fekher Thank you for your response, we well conduct experiment about your suggestion
  • noorahfmnoorahfm Member
    Fekher, how many % will derease LAbsa and increase SlES? 

  • FekherFekher Member, Professional Chemist
    @noorahfm you must work for that just to help you LABSA can be good in 2 % .

    I don't think you'll need that much NaCl. Try adding that salt smaller increments just to thicken it as needed.

    For a mixed hand/machine washing liquid detergent you can add some extra SLES (to 6% or so) to thicken it without needing salt, and to improve flash foam.

    For a machine washing detergent, you can remove SLES and increase LABSA to 20% or so. It provides extra cleaning, without SLES foam (for machine washers the less foam the better).

    @Gunther Will the 20% LABSA clean dirt or dirt and colour what I experienced ?

    Of course that will clean dirt
    As for the color, it is a faint yellow.

    what then would be the %NaOH? will it remain the same
  • GuntherGunther Member
    I have only used neutralized LABSA,
    the NaOH % will vary a bit from supplier to supplier and even from batch to batch.
    I rarely use NaOH as it's alkalinity seems to degrade LABSA. Now I use Sodium carbonate and wait for the bubbles to dissipate.

    Sodium alkyl benzene sulfonate should be a pale transparent yellow, no matter if it's neutralized with NaOH or carbonate.
    And yes, it cleans clothes fine on its own.
  • Gunther, and Fekher I again say thank you so much for your cooperation for solve the problem,i solve the problem when decreasing Nacl and LABSA and increasing Sls ,
