dish wash liquid concentrate
Posted by Avirock on February 26, 2018 at 7:00 amHello friend I need your Assistance on Dish wash Concentrate. I
have make Concentrate with following ingredients. I want to mix all ingredients
without water and make Concentrate liquid. I do but when I neutralize the labsa it will become very thick paste.
I want liquid.860 gm Water
94 gm LABSA
12.5 NaOH
27 gm CDEA
1 gm EDTA
2 gm Sodium chloride
Any piece of advice, suggestion or hint
Thanks

A hydrotrope might come in handy but that will affect the foam profile. It could be a glycol or Na Cumene Sulfonate or Xylene Sulfonate, try if these work and you end up happy with the foam quality.

Thankyou for your for your valuable reply.
But sir I request you could you please explain indetal.
Thanks -
when I neutralize the labsa it has become very thick paste. And if I add water in labsa it has also become very thick past is there any way to do same and get less viscuss gel. Thanks
-
Can you please note down your complete procedure here, will be much better in making any suggestions/recommendations. Also please list diwn your formula in % and not in grams.
-
Thanks for your reply.
Please get the following information.
Water 86.3%
LABSA 9.4 %
NaOH 1.25%
CDEA 2.7%
EDTA .1%
Sodium chloride .2,%

What is the order of addition, that much shouldn’t make it thick as it is almost a regularly used dosage.

Dishwashing concentrates contain water. They just contain less than non-concentrate products.
Try increasing the concentration of your actives (and reducing the water) and see how concentrated you can go before the viscosity is not acceptable or the product is unstable.
As Chemist77 mentioned Sodium Xylene Sulfonate can be added to help reduce viscosity in concentrated formulas. Also you could try some ethanol to help reduce the viscosity a little.

how i mix(neutralize) labsa and NaOH flakes without of help of water. when i mix with NaOH + water it will become thick paste.
-
While rereading your question I just realized that you are trying to defy chemistry. Once you neutralize it is going to be thick, end of.

@Avirock actually i did the experience with Labsa 10%, NaOh 1,2 % without CDEA even with using different quntity of slat it dosen’t lead to good viscosity it stays too near to water viscosity even i see that with using perfume the bad smell of Labsa at that level 10% still exist and finally with that formula some collant effect found and it is bad thing.
So as conclusion making dish wash liquid with only LABSA and NaOh is according to my experience is very bad idea.
I did some correction for my formula by reducing LABSA % by diluating, adding SLS and CAPB so i obtained acceptable product with good foam, acceptable odor and not very low viscosity. -
Most dishwash liquids use SLES, not SLS
but you can always try with the latter to see if foam gets better.Be aware that SLS is more skin irritating than SLES (albeit Sodium sulfonate is irritating too)
and if SLS comes in fine powder form, it can irritate your lungs.CAPB was a bit pricey for an economy product
so I just added more LABSA (+NaOH) and SLES to get more foam.
