natrosol ftw

Calculate total batch weight.
with a small amount, adjust in the lab with primary surfactant until you have rebounded from the salt curve. then just do the math
sx wt + ing wt = total wt
ing wt / total wt = ing conc
ing conc * batch wt = how much to fix your stuff.

Sodium Lauryl Ether Sulphate (SLES) = 22%
Coco betaine (CAPB) = 5%
premix
poly 20 = 0.30
Perfume = 0.15%
add to batchPreservation (glydant +) = 0.15%
Dye = 0.05%
Critic Acid = qs%
Sodium Chloride = qs%
Water = qs%tada!

@Dilfre no these chemicals are different in structure and in behaviour
-
@chemicalmatt thanks! yeah my salt is around 2.5% right now, are you saying I can bump that up quite a bit? I don’t have a homogenizer yet so I’m relying on a high sheer blade and high rpm. Also at “the end” are you talking about the cool down from the 50° to ambient?
-
It actually came out clear in my solution, but you are right its incompatible due to it failing hplc haha. Yeah i don’t know what I was thinking, i think i just got caught up in trying to make something quick without researching
-
@Bill_Toge hey thanks for the info! my lab will soon be getting a homogeniser so I am stuck using a “chopper” blade till then.
-
Im saying in your formula .01%-.10% w/w
-
.01% to .10% ; takes a little bit to go into soln, unless you got the aq version, so in teaspoons, I guess it’s like the very very tip of the spoon like a grain on sand haha

Maybe some polyquat conditioners?
-
@perry parabens are safe to use, despite what has been written. Do you concur?
-
can you get some (glydant +) or phenoxyethanol? Store it in copper? Do you need a natural preservative?

Alright took another stab at it. I’m using cetyl OH so i have to heat this up to around 75°C. My homogenizer right now is a propeller blade that is bent up real extreme. I pumped that up really high poured the water in the oil and continued to aggressively mix till it got down to ~35°C (no force cool). Then I noticed it starting to floccuate a little bit (breakdown) so stopped it and paddle mixed it and it magically went from a matte finish to a nice glossy shine. so weird. anyway got down to ambient temp and in a jar so hopefully i dont get any coalescing, we’ll see. I’m a little scared to put it in stability at 45° or in the centrifuge. Thoughts? Primary - Abil WE 09 ~10% CoEm- cetyl OH ~5% …. water ~70%~ I’m thinking I can raise HOH and lower Primary and still get a large visc without breakdown … Thoughts?
-
yeah put together another go at it flipping the oil phase emulsifiers with the primary being the higher percentage at 11% and the co emu at 8%, fell apart around 40C.

Hi thanks for responding, my primary is ABIL® WE 09. I’m not sure I want 73%, I just want a high viscosity lotion ~30k cps. Should I be high sheer mixing for longer than 5 min before I switch to paddle mixer? This is just a lot different than o/w
