DLSS-disodium laureth sulfosuccinate (powder)
Hello,
recently i got DLSS (powder) and i never have worked with it. Some say it is simular to SLS (working) but with powders i dont have any experience. I tried to make 20g of dlss and 100g of water and it just become white paste after night, even 10/100 didnt work. How can i get to be clear liquid (27%) and can i use it as primary surfactant (the mildest in anionic i think) ?
Thank you
Greg

Rencelji - some info on DLSS and how to use it - http://swiftcraftymonkey.blogspot.co.uk/2010/04/surfactants-sulfosuccinates.html

I did read that but there is no information at all for powder DLSS and how to work with it. I know really well that blog, but like i said. On internet (i couldnt find) is no info how to work with powder at all. And i have no experience with it also. On blog it is writen 32% active , that mean 32g of powder to 100g of water, but it will be just white paste -almost solid when will cool down. Really will be pleased for any info with DLS. Lets say if i make shampoo with DLSS as primary surfactant (powder) and betaine, how would i mix powder in to get 27%-32% active and not white paste?
Thank you again

Sample formula - http://www.clr-berlin.com/files/243_03_0401_herbal_body_cleansing_foam__sles-free.pdf32% active doesn’t mean to add 32g to 100g water.Here’s more info on what 32% active means - http://itsallinmyhands.com/2013/04/23/on-surfactants-and-formulation-face-wash-shampoo-and-shower-gels/

Hey, thank you for link. I see the point and thank you again for that. But how would you make with powder 32% active surfacant ? Just for dlss. To disolve in water i find it quite a big problem, since when it cool down it get almost solid paste.

See the sample formula posted above for how to work with DLSS.

I saw the formula, but i would like to learn how to actually make 32% active in liquid form. I tried 3.2g DLSS powder and 6.8g water, it become just white paste. So i really have no idea if it works like this .

A shampoo for normal hair, might only have a total active concentration of 13%. This 13% is comprised of a blend of surfactants.
For example Ammonium cocoyl isethionate (30% active) used at 15%, Decyl glucoside (53% active) at 8% and 15% Cocamidopropyl betaine (30% active) makes a total active concentration of 13.24%. The rest of the formula will consist of water, viscosity modifier, conditioning agent, pH adjuster, preservative, fragrance etc.You should use a blend of surfactants rather than just one.The formula I linked to above, uses DLSS at 5% so if you were to experiment with it at 5%, this means it will be 1.6% active concentration. If you’re looking for your shampoo to total 13% active concentration then you’ll need to add other surfactants.Do have a read of this - http://swiftcraftymonkey.blogspot.co.uk/2009/03/surfactants-short-guide-to-things.html -
MakingSkincare… indeed you are right about the amount of effective DLSS inside of a shampoo… but I think Greg is mostly concerned about first making the liquid form of DLSS (which is made of 32% active matter + water and preserving system and glycerin (maybe) for the remaining 68%).
What I already told him is that it is not that easy to make a liquid surfactant from a powder one (and this is why on websites that sell cosmetic ingredients, we 99% of the time find already liquid surfactants!).Adding the powder in lower concentration directly into the shampoo formula doesn’t sound that easy either.Greg… the paste which forms after it cools down… is it totally white?Have you tried keeping it and checking it after a few days?My liquid (32%) DLSS is very thick and dense but it is transparent… -
Thanks Itsallinmyhands. Welcome to the forum.
I have used powdered DLSS in my shampoo/body washes without diluting it first so I’m not sure I understand why he wants to do this. -
Ok if you have had experience with this then he could indeed try this way!
ps. Thank you!

Hello all,
thank you for answers to all. I couldnt reach internet those days therefore i couldnt answer you. Like Itsallinmyhands said, i was trying to make detergent to than mix it in shampoo. And have really problems with it. Even putting in formula you posted isnt going right. Powder is consider to be 100% right ? so 5% it means 5g of that formula u posted MakingSkincare ?
Itsal: yes, 1st when i mix it with hot water it mix ok but there is lots of small bubles on top that covers the top of liquid. When it colls down it it like clay paste/white paste. I didnt try leave it more than 1-2 days, but can also try that ti se if will clear but i really doubt it.

Yes that’s why I heard a cosmetologist explain that this is the reason why 99% of the times surfactants are NOT sold in powder. Apparently it is not so easy to make them be in the liquid state (unless one is a professional and knows how to do it
I guess). As she said above, if you want to follow that recipe which says DLSS at 5%… you have to actually use the powder at 1.6% (I quote MakingSkincare: “The formula I linked to above, uses DLSS at 5% so if you were to experiment with it at 5%, this means it will be 1.6% active concentration. If you’re looking for your shampoo to total 13% active concentration then you’ll need to add other surfactants.”)Where, obviously 1.6 is the 32% of 5!Understood? The fact that it forms bubbles should be quite ok, after all it is a surfactant and they will go after a while.However… did you try adding a little of glycerin as I told you before?
