whats the best way to dissolve texapon(sodium laureth sulfate) in water?
whats the best way to save time in dissolving texapon? its time consuming…

What are you using for? I dissolve it in sulphonic acid for dishwash.
-
disperse it in hot water and use a high-shear mixer
-
I want it for hair or body shampoo ..when I mixed it wih water it takes about half hour.. maybe there is a better way to dissolve it. even I try NaCl solution but there isnt any change.
-
Are you using needles or 70% active? Check whether it is 2 moles EO if it is in paste form.
-
whats needles?
I use 70% SLES and its in paste form. -
Try to use lukewarm water, might help a bit I suppose. As I told you check the EO moles with your supplier.
-
whats EO ?
-
EO is Ethylene Oxide, I am sure you are well aware of ethoxylation and if you remember we had a short discussion too about this
-
whats a relation between EO and dissolving of texapon?
-
What do u think is texapon????????????
-
Texapon is Sodium Laureth Sulfate. The ‘eth’ part of the Laureth refers to Ethlyene Oxide. The more EO in the molecule, the more water soluble.
TEXAPON N 70 NA - has an average of 2 mols of EO -
@perry will I be correct to say the more the EO the more foaming the laureth
-
@perry is there a way to increase the speed of dissolving texapon?
-
@Bimsmide - it depends on how the EO effects the CMC point of the surfactant. I’m not really sure there is a general rule but it’s probably more EO with increase foaming of laureth to a point. I’m not sure what that point would be.
@nasrins - Did you try hot water and high speed mixing? You might also try pre-blending it with something else like Glycerin or some other liquid in your formulation. -
@perry I think both hot water and high speed arent good idea. with hot water adjusting viscosity becomes difficult and with high speed foam is produces. even I try to dissolve texapon in nacl solution but it doesnt work.
-
30 minutes doesn’t sound like a very long dissolution time to me - and if you can’t increase your water temperature or your mixing speed, you are stuck with it. The only alternative would be to buy a less-concentrated grade.
-
@nasrins - I don’t understand why hot water would make it harder to adjust viscosity. Wouldn’t you just heat it up then adjust your viscosity when you cool the batch down?
-
@perry I know that heating increases the solubilizing process but I think there sould be a good other way.
-
I know of no better way.
-
thanks perry
-
What blade are you using? When I use texapon the homogenizer helps to break it down faster and better than a chopper blade.
-
You should heat water up to 70degree
-
High steer is next reason and i think an other way is available
-
i use this one, with high steer the problem is bubbles.
-
you can make a reverse process like first add texapon into the main vessel and add slowly water in it with continuous mixing may be it will work for you.
