I have used Iselux sfs sb recently and tbh didn’t find anything unusual in terms of odor. Is it a fresh sample or old because the old sample of mine smelled horrible. I have used only 0.2% fragrance and it smells pretty nice.

Great article @ozgirl.

@Ghandi you mean a formulation to produce commercially without spending a dime???
-
I remember long time back coming across SISTERNA, check and you will find a starting formulation for an edible cream. Gel not too sure tho.
-
LABSA needs to be neutralized here, can’t leave it unneutralized. Neutralization will convert into sodium salt which then becomes a surfactant. I don’t see a need for sodium sulfate, not sure what’s the need here. Generally a filler/bulking agent for powder laundry detergents, use sodium chloride and it should thicken the solution. Next time post your formulation in percentage to make things easier for those who try to advise.
If the solution still remains thin, then there are not enough surfactants and you would need to increase everything in little increments. -
Try sodium chloride, get rid of carbomer and cmc. Simple!!! And you never neutralize SLES, period!!!
That SLES though is going to leave good amount of residue on the floor after cleaning, FYI. -
Not knowing too much about your conditioner, I suggest that you try to wash a lab beaker/vessel with LAS and where you would apply a little conditioner to the walls and bottom of the beaker/vessel. LAS is used extensively in H&I and I use it for my dishwash liquid in neutralized form. If there is no complexation of LAS/NP9 mixture with your cationic (which I doubt might happen) then you can give it a try. Note that it is an acid and very corrosive so even that might pose an issue to your filling machine parts. I remember @Bill_Toge and @DRBOB@VERDIENT.BIZ advising you on the same and those looked good enough measures IMO.
Surely someone can chip in with a better perception here, @chemicalmatt generally comes to mind in such ‘nowhere to go’ situations. -
These are for oil phase, check the compatibilty if the supplier has provided you with the PDS of these products.
-
Yeah but I have never seen TEA being used for a dishwash liquid, generally sodium hydroxide will do the job.
-
That’s very surprising, why don’t you get it done by a third party just to make sure.
Also I noticed you have NaOH and TEA both, specific reason here or just want to use a combination of alkalis. -
It seems 3-4 ingredients are lot for you, good luck then!!!
-
That must work as I just gave you the commercial formula.
-
Add PVP but remember it will disturb the clarity. Process at 85C since below that it is quite difficult to get a uniform product. I have used PVP K90 at upto 3% but compromised on clarity. IMO the hold of wax itself is perfect, I added PVP since customer was insisting. Should be slow mixing and you will have no issues.
Good luck. -
Surface cleaners are not really viscous even if you want to dilute it. Why don’t you use Benzalkonium chloride as someone suggested @2-3% and you can still dilute the final formula upto 20 times. Use a non ionic surfactant like an APG at around 0.5% and another non ionic like Berol 260 @1-2%, it will give you a milky emulsion. Use a defoamer @0.005% level to minimize the foam while cleaning.
-
I have got it right every time I do the trial. Just follow what I suggested, get the base right first before you add the additives.
-
@Bobzchemist simply brilliant. I always had to make new batches when I was doing shade matching for liquid foundation.
-
Generally its the loss of actives in certain cases, you will have to do microbial testing to check the efficacy of those. Maybe you will need to add more to preserve the formulation, recently I had the same dilemma with Phenoxyethanol and I was told to check the active. Either I could increase it in the final formula or send it back to supplier who would then top up the lost active content.

Forgot to mention that it is again all subjective to the quantities you use. For us it is liquid enough to process at RT but if I go higher then maybe a process change wouldn’t be a bad idea.
-
Generally we always do at RT since the end result is going to be same, further if not HP then why heat at all.
-
A 20% dilution approximately of DC CE 0101 with other things thrown in should do the trick for you. Have used the same for my make up remover wipe solution.
-
Homogenization has been quite a help for me.
-
Well I have seen it in antiperspirants and similar products, again everything changes as per the formula. Have a knockout done with that formula of yours.
-
Try one batch without it, should give you an idea. That TSF 405 foams too, and that could be the source as well since 15% is indeed a high dosage.
