How do you manage navigating all those tabs?

Hi, it looks like you’re missing an emulsifier here. Your fatty alcohols can support an emulsion but they won’t cut it on their own. A pretty common one in conditioners is Glyceryl Stearate SE.

I would read this as more monoethanolamide.

I think you’re looking for pre-dispersed polymers/thickeners such as:
Aculyn 22 (Acrylates/Steareth-20 Methacrylate Copolymer)
Crothix Liquid (PEG-150 Pentaerythrityl Tetrastearate (and) Aqua (and) PEG-6 Caprylic/Capric Glycerides)
Carbopol Aqua SF-1 Polymer (Acrylates Copolymer)Look at the literature for each as the Aculyn and Carbopol need to be neutralized to get your viscosity. You might have to add a bit more than 0.5-1.0%.

It doesn’t seem like you listened to any of us when you posted this same thing last time. How would you like us to help you when you don’t help us?

It seems this post was made at the same time as the one I linked and isn’t a copy of the last post, my apologies.
We still need the information requested to be of any help.

Could you share your formula or at minimum the list of ingredients? Expansion can be a preservation issue.
-
Glad you could confirm you do indeed have skatole.
I’m even more curious about the application now. Is it one of those bathroom sprays meant to eliminate malodors if you spray it in the bowl before doing your business?
-
I don’t have an answer to your question, but I do have a question of my own. What is your intended application? Fragrance?
-
Based on the ingredients listed and the amount of information we have, I’d say the issue is a lack of water.

Use as little biotin as you possibly can, then filter your bulk before filling.

Hello,
I’m part of the R&D team at a contract manufacturing company based in South Florida. My colleague is working on recreating this product right now. He’s been successful in the lab and is trying to find equipment to scale up his process as we speak. If you’d like to set up a meeting to discuss specifics, feel free to send me a private message. -
In manufacturing, a batch needs to have its pH raised or lowered to meet specifications. Usually, the pH adjuster is included in the formula and we simply have to add a bit more at the end. However, it does happen that a formula doesn’t have one or it contains an acid but when we measure pH it comes out too low and we need to add an alkaline pH adjuster. We often use sodium hydroxide for this as it’s cheap and we have a lot of it on hand. This would be classified as an incidental ingredient and does not need to be disclosed on the label. So there is a good chance that other products you use also contain sodium hydroxide but don’t include it on the label.
When you say salt water do you mean specifically sodium chloride? That may happen if there are other ionic ingredients in the formula that release a chloride ion when dissociating. Depending on the formula, there could many different sodium salts “formed” but the concentration would be incredibly low. I put that in parentheses because most sodium salts are soluble in water so the sodium would remain as a free floating ion unless all the water is removed.
-
To answer your question, I find it highly doubtful that there could be undissolved sodium hydroxide remaining in a product. Sodium hydroxide is not added as a solid. Generally, it is dissolved in water before being added to the product to ensure it disperses quickly and allow the compounders greater precision when weighing it.

There are many other choices. @PhilGeis has listed some of them above. Do you have any other constraints when it comes to preservatives?
-
Unfortunately, I don’t have an answer. I haven’t seen those units of measurement and google isn’t bringing anything up after a 10 minute search.
-
True, though it is a start.
-
I think you forgot to answer a question.
-
Hey Ray, why do all your comments sound like AI and include a link?
-
Add more ceteareth-25 or replace some of it with ceteareth-30 or both.
-
Weird, I added the whole brochure and only the first page is showing. In case it happens again, the INCI is [Glucosamine HCl (and) PCA (and) Glutamine (and)
Lysine HCl (and) Betaine (and) Yeast Beta Glucan]EDIT: It seems you have to download the file to see the rest of the brochure.

Would this material happen to be ScentARC?
-
It can be dispersed in polyols such as propylene/hexylene glycol, propanediol, or a blend of these and glycerin.

Replace all instances of cationic here with anionic. I replied a bit too early for my brain to be working properly.

What I’m saying is there are no byproducts unless all the water is removed or there is a molecule that makes an insoluble salt with sodium. The latter is very unlikely because sodium salts are soluble in water with exceptions that wouldn’t generally be seen in cosmetics such as sodium bismuthate. All that will happen is the sodium will hover near cationic molecules or water. If the water is removed, the sodium will then form salts with the cationic molecules it is most attracted to.
