And seriously, @ngarayeva001 , @Chemist77 , @JOJO91343 , and @Belassi , thank you so much for your input and taking the time to help me troubleshoot this. I know you all are busy, so I appreciate your time and expertise.

@ngarayeva001, I had actually started wondering the same thing. The two surfactants had come from Essential Wholesale.
@Chemist77, thank you. I’ll check out the HPMC!
-
Took out the HEC. Still get a tacky feel upon drying even though it is less. Also tried a batch with a lowered fragrance level so less poly was needed (0.3%). Increased chelant to 1% and it definitely improves the feel, but there is still that tacky feeling upon drying.
-
I really hope it’s not the HEC though…it’s had a nice impact on the foam.
-
I should add, I reworked the surfactant levels a bit, so knock outs are going on now on a re-worked formula.
-
Chemist77 said:Did u knock out HEC and check if that’s the culprit.
I’m going to knock it out next (up working now). But previous batches without it still had the same stickiness.
-
But thank you for the detailed explanation on Carbopol. I’ll make sure to bookmark this because I know that will be very useful later. So, I do appreciate it!
-
Sorry for the confusion, @JOJO91343. It’s cocamidopropyl betaine, not Carbopol.
-
* it being fragrance. Sorry I wasn’t more clear above!
-
@Belassi, do you think increasing the chelant could improve the skin feel?
@ngarayeva001, I’ve also dropped it down to 0.5%, but the stickiness was still an issue. Actually the last batch where I did no poly, the fragrance load was at 0.5% and that was one of the worst ones I had had in terms of how sticky it was.
-
Fragrance* I can’t phone type. Sorry.
-
It is. But the frangeande does not seem to be solubilizing effectively without it. And surprisingly, the batch I tried without it was actually stickier. Made no sense to me. Same ASM, no poly, and stickier.
-
@ngarayeva001, the ASM is already quite low on this (in the 5% range) m, but I’m wondering if decreasing it further may help?
-
That formula shared is already cut down. I thought it was strange as well. I’ve varied the levels of ASM also. It’s quite low now and the tacky feeling has improved, but it’s not gone. I thought I had read somewhere that chelating agents can help as rinsing aids, so I was wondering if and increase in the chelator could potentially help. I’m at a loss at the moment.

Thank you!

Catherine, 1:4!

Thank you both!

Thank you!

Thank you, @Belassi !
-
@chemicalmatt, can you recommend a surfactant that would allow for the product to be clear. I appreciate it!
-
@MarkBroussard, can you recommend an incubator? Thank you!
-
Definitely not interested in anything illegal. Located in USA!
-
Thank you, Gunther. That is very helpful. I agree that a rented space would be best. What if I just wanted to do stability testing? Are there any particular incubators you would recommend?
