Polysorbate 20, 80 for AHA facial cleanser or toner

@Jdawgswife76 if it is cleanser SA is soluble in SLES up to 2%.

Unless you have changed to DOREEN, I dont beleive that comment applied to you so maybe you should of read carefully! I was not impolite. As i stated in my post SOME like 2 people actually provided useful info. I did not ask for SA 101! I have actually received the simplified information that i was looking for Via a helpful e-mail and i do not ask for anyone to give me “exact mount” and AGAIN i had been performing tests and researching. It was a simple question. You must have missed the part where i said out of all the jibber jabber posted MOST not all was even necessary. Doreen made a post because thats what this sight is for. Please only comment helpful information. Your long winded speaches with zero knowledge and feedback does not help the person looking for assistance. Again I have gotten what I need so all other posts here are irrelevant. Thanks to the LIMITED peoplethat actually provided useful info.. MERRY CHRISTMAS. . ..

@Jdawgswife76
You seem to misunderstand the reasons why some things are mentioned, it’s NOT to make you look stupid or to discourage you from experimenting.Regarding only ‘idiots’ that make aspirin masks: google it and you see it is done by a great number of people. Even a long time member on this forum has suffered a salicylate poisoning through a gel/cream some time ago. It can happen even in lower concentrations in certain circumstances, like I wrote.
A lot of GP’s don’t even recognize a salicylate poisoning when they get it in their practice.
It’s only because of my pharmaceutical background that I know this very well.
I was only trying to warn you.

And Google why most OTC sports ointments and wart removal creams withdrawn salicylic acid and its derivatives from their formulas.
There’s even a Wikipedia entry for it

@Doreen I completely understand and if i took things out of content I apologize. It just seemed to me as though I was being treated as though I knew nothing and did not do my own reserch and experiments. Again if that was not the intention, I am very sorry! It just gets very frustrating when your trying to work with something knew and you research conflicting info and I waste ALOT of product experimenting and you just ask for some different input and get alot of othet stuff that doesnt help with issue at hand. I completely understand this comes with the world of cosmetic formulating, however there is alot of chemistry, science, and other factors that play huge rolls and not just knowing ingredients. So again my apologies If i took it wrong! Thank you for trying to help I really do appreciate it.

There is alot of conflicting information on here as well. There can be scientific studies /experiments, etc, however it still comes down to other factors and one scientist says one thing and you find another says the opposite when your researching these ingredients. The same with HA and the debate regarding the weight LMHA and HMHA. Its all over the place and inconsistent info from what I have been researching from chemist to scientist. So its just frustrating.. . I hope everyone enjoys there holiday and thank all of you for your time.

MarkBroussard said:Yes, you can use a combination of 1,3-Propanediol @ about 20% to 30% + 1% Sodium Citrate … if you’re using SA in the 1% range, that should do the trick. Keep your final pH around 3.8 to 4.0.
Thank you Mark as well for your help on this and being specific. I disnt expect any exact usgaes or formulas but i greatly appreciate the extra mile.

https://en.wikipedia.org/wiki/Salicylate_sensitivityI have seen this as well and my opinion again is simply formulation, percentages , etc. SA is perfectly safe if formulated and used correctly.

Salicylate toxicity (primarily from Methyl Salicylate or Oil of Wintergreen) is rare but still a concern.Salicylic acid is routinely used in hair care and skincare at less than 2%. The real challenge is in solubilization.Early on someone suggested searching in the forum. It is possible. The reason this is of value is that there are several threads on this recurring topic. Failing to review the old threads will steal the opportunity from you to get some useful tips.It can be tricky, requiring various solvents, oftentimes ones not as welcome in a “naturally compliant” product.My last comment is that I would highly suggest that you follow the guidelines as outlined in the Cosmetic Ingredient Review, https://www.fda.gov/cosmetics/productsingredients/ingredients/ucm107940.htmIn this case, the general practice is to lump the BHA’s into the total AHA’s. For example, 5% Glycolic plus 5% Salicylic Acid would be 10%.
Please don’t get in a tizzy, but if they are out of the guidelines above, they are not really for a Home use products and MUST be administered in the clinic, by a qualified Professional. To ignore this is reckless, negligent and unsafe. I would suggest that anyone on the fence consider intelligently the level of liability and their comfort for risk. After 30 years, I would never risk allowing a client to use a product that exceeds these published credible warnings. -
I am aware of all the safety and usages for SA. I have read a ton of threads and have Not Failed to read them. As I stted earlier, same that goes with my research with this particular ingredient, conflicting info is everywhere by everyone! Scientists, Chemists, (want to B’S) you name it. People experiment on diff levels and this seems to be a very unstable topic. But again I Am PERFECTLY well aware of the safety for this ingredient that is not the info iam concerned with. However once again thanks for attempting to help.

This threads are open and will often evolve into discussions much wider in participation than the original post. No reason to be so reactive.
-
(1) Heat the 1,3-Propanediol to 70C, add the SA to the hot solvent stirring until is dissolves
(2) Add Sodium Citrate to water, heat to 70C
Slowly pour the hot SA solution into the hot water. Add the surfactants and any other ingredients you desire.

Ty @MarkBroussard…

@Microformulation And? Discuss on I didn’t say I expected the discussion to end. Some people just comment due to nothing better to do i guess. Lol I hope it does continue on maybe someone else can use the valuable information that SOME people have contributed. ..

This is at heart a board for Professionals. We all need to act accordingly. This thread will be searchable training asset for those who will come in and search for solutions to this problem.I will not respond in a reactive manner. It accomplishes nothing and does not further Cosmetic Science in any manner.

1,3 propanediol is used at 1-10% so ate you saying use 20-30% citrate? Isnt that a bit high? Just checking
-
No, I mean you’ll need at least 20% - 30% 1,3-propanediol to keep the SA solubilized. Sodium Citrate you would use at 1%.

I got all done last ty. I finally played around with it and got it. Turned out great finally
Thank you all that helped out! ! Ended up with a great face wash. ..
