  • Where can I find this rare ingredient? Please help!

    Hello! First, some background to my question: I’m working on my first formulation. I’m creating an oil-based cleanser that’s fragrance and essential oil-free, non-comedogenic, non-stripping/drying, removes makeup and sunscreen, washes away cleanly, and doesn’t leave a tight feeling behind on my skin. It’s a big ask, but I’m up for the challenge. So far, I’ve found one product on the market that meets all but one of these requirements: Botanic Farm Grain Ferment Cleansing Sherbet (unfortunately, it’s not fragrance-free, which is a big deal for my very reactive/rosacea-prone skin). I strongly feel the other requirements will be made or broken by the emulsifiers.

    Since this is my first attempt at formulating, I want to go simple with it: I only want to combine Rice Bran, Hemp Seed, and Red Raspberry Seed oils with the two emulsifiers from the Botanic Farm cleanser (PEG-20 glyceryl triisostearate and PEG-10 isostearate) to make an oil to milk cleanser. Note: I am not currently asking for formulation help, as I haven’t even attempted to make this yet. Also, the texture does not have to be a balm/sherbet - I’m happy with a liquid formula. 

    With help from ngarayeva001, I have a supplier for the PEG-20 (The Formulary and Glamour Cosmetics), but neither of us has been able to find a supplier for the PEG-10 isostearate. To me, it seems like the difficulty comes in the rarity of the raw material; I can only find 2 producers/3 products on the market:

    1. Nikkol MYS-10
    2. Nikkol MYS-10V
    3. Radiasurf 7473

    On to my question: Does anyone have a resource for a supplier of this material? I am located in the US, so ability to ship to the US would be ideal. I would prefer to purchase retail quantities as well.

    Follow-up question: If this raw material is actually impossible to source, does anyone have suggestions for potential material substitutions?

    Thank you so much!

    To add to the above, I attempted to reverse engineer a very similar korean balm (banila clean it zero) multiple times with almost identical LOI. I have all ingredients but PEG-10 mentioned above and apparently it’s the most important ingredient in this product. I would also appreciate if anyone knows a good replacement for it because I don’t believe it can be found at repackers marker.

    Thank you, but ulprospector only sends samples to companies who can prove that they are not dormant and can provide recently issued invoice. I believe that the question is about a repacker who is willing to sell amounts around one kg. I spent some time looking for it myself and don’t think it’s sold anywhere. So it would be great to know whether there’s a good replacement.

    I don’t have an answer for this but you might try either http://knowde.com  or http://chemberry.com  They are less strict about sampling the UL Prospector.

    Thank you @chickenskin! I’ll look into sourcing that material as an alternative.

    Great resources @Perry! I’ll follow up on those and see what I can get.

    I’ve had success making an oil-to-milk with the PEG-20 glyceryl triisostearate on its own, so you may not need the PEG-10 at all

    @LincsChemist, I think that’s going to be my first attempt for sure. What % of PEG-20 did you use? I was thinking I’d start with 15%.

    @essenceofllama I used 10% - it’s pretty mild though, so I’d think you would get away with 15%

    Total surfactants should be close to 20 to get more or less good rinse off. That’s what I figured for balms. You need less for cleansing oils.

    @LincsChemist and @ngarayeva001 - Thank you both! I will begin testing formulas as soon as all of my materials arrive!

    after I saw you both ( @essenceofllama  and @ngarayeva001 )  comment on it in another thread I also attempted to look for it. That ingredient is some kind of magical balm-only material, it’s also in the  farmacy green clean balm . I did find Nikkol which in my US location is distributed by KOBO but I only saw Peg-10 stearate not isostearate. 

    That Ethox product is PEG-9, not sure how much difference it makes. My current guess is it’s got to be from china.

    @EVchem, I totally agree. I only saw it in balms: https://incidecoder.com/ingredients/peg-10-isostearate
