liquid laundry detergent down in the bottom of bottle
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%

@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
-
Fekher, how many % will derease LAbsa and increase SlES?
-
@noorahfm you must work for that just to help you LABSA can be good in 2 % .

waterI 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 ?

Gunther Thank you for your response,
we will try to cover that problem with help of your experience. -
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. -
you are welcome @noorahfm

Use the following stable formula;
LABSA (96%) 13%
CAUSTIC SODA 1.56
SLES(70%). 7
STPP. 1
EDTA 1
NACL. 1 -

NACL. 1IMO refrain from using NaCl if it has good viscosity on its own, otherwise cloud point sharply rises with salt.
You can easily try it yourself:
Make some of it
then pour some in a bottle as it
pour the rest in another bottle and add some salt
put in the fridge without freezing
the one containing salt is likely to become cloudy.EDTA is a salt and likely to cause the low temp cloudiness problem as well
1% EDTA is too much, 0.1% is enough.Is STPP Sodium TriPolyPhosphate?
If so, phosphates are banned or frowned upon as they lead to rivers and lakes eutrophication, so it’s better to get rid of it.If you need to increase viscosity, some CAPB can help without rising cloud point.
