    I agree with @ketchito, focus on what the FDA has approved for use as skin protectants and work your way from there. This is what they consider skin protectant actives:

    https://www.ecfr.gov/current/title-21/chapter-I/subchapter-D/part-347/subpart-B/section-347.10

    I also have eczema and found that a generous amount of skin protectants, humectants, and occlusive agents worked best for me. I looked into making a two part treatment a while ago but have settled on only using the colloidal oatmeal moisturizer (linked below). It has greatly reduced the frequency and duration of my flare ups. If you have any questions about the formula feel free to pm me.

    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.

    I also premix certain gums with glycerin. I found that adding the premix in aliquots and mixing thoroughly in between helped reduce the amount of fisheyes or agglomerations I saw.

    Which gums have you tried?

    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.

    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.

    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.
