    If you use a reliable strain of hemp that is known for it’s low THC content it’s very hard to end up with a high THC CBD-oil; it’s an extract so you will only be able to extract part of the (already low) THC content of the plant. I am sure you figured this out already. Unless you start concentrating the extract that is.

    Anyway’s…, I do agree that without testing it’s hard to know how strong your CBD extract will be. Maybe an alcohol extract is the best way to go for you (if you want alcohol to be part of the process/product) I mentioned an oil extraction, but on second thought I think that would be impractical. You cant’t concentrate an oil extract after you made it. With an alcohol extract you can evaporate solvent to end up with a high CBD content. CBD testing isn’t that expensive in Europe. I am not sure if there is a reliable affordable test for CBD. Testing of the same sample can give different readings if my memory serves me well..

    This might be a good starting point for you @Graillotion:
    It’s more complex then the THC vs CBD relation. But broad spectrum is our friend basically :)

    @Graillotion
    CBD, I think, works better in it’s natural context (at least some of it). The “entourage effect” means that if you use a CBD product (in this case) in it’s natural context it works better. Especially the dose-effect relation is much less critical when you use a broad spectrum CBD product for your cream (or per oral).

    With CBD I would alway’s opt for an simple and easy oil extraction of the hemp plant to obtain my broad spectrum CBD extract… No alcohol involved…

    For the same reason THC pills, for example, are known to cause side effects ppl. don’t experience if they use it in it’s natural context (headache)

    Never “start” a company just to get samples. It makes it harder for the rest of us, and the companies participate so they can sell product.

    Don’t worry I wasn’t serious

    but please don’t post any more additives I can’t get or I might resort to it ;) (no, I am not serious, just kidding)

    @Microformulation: I might have to start a company just to be able to get the ingredients I otherwise can’t buy. Madness ;). luckily I actually like the hunting

    …you might wanna add 2% niacinamide for claims.
    https://doi.org/10.1080/14764170600717704

    interesting thought… It absorbs sebum and aids in a more matt look that way… Not an ideal choice for a dry skin I suppose though. I once reacted to niacinamide (via oral). So it’s not for me… Thanks anyway

    @F@Formulator: thanks, I might want to look into those emoilents as well. See what it’s like…

    I am having a hard time finding actives/ingredients/chemicals actually. I live in Europe (I am Dutch). I can source stuff much easier in the US via internet, no problem. Especially the more synthetic ingredients seem to be harder in Europe. Not as much variety also…

    Thank you very much Bill, I will keep that in mind. Silicia is the most likely thing I can get. It’s on my radar :)

  • In addition to what RedCoast suggested you could leave the two extracts out. Just to eliminate.. You never know :)

    INCI of the cream that (I think) is mattifying…

    There are quite a bit of “texture enhancing” ingredients in it. I am wondering if a mattifying ingredient might be listed as “texture enhancing”?

    Or maybe the absence of oils and butters? Make this day cream less shiney? (or the Silicia)?

    Thanks, that’s a lot of info already :)

    So I could try:
    Illipe butter
    fatty alcohols (some of them)
    Greensil from Greentech
    Montanov 202 emulsifier

    And basically trying to start out with the least shiney of oils and butters… Sounds logical. Good point. That needs some experimenting!

    I could imagine a certain percentage of a drying oil could help/aid in achieving a matt finish too? It makes the skin feel stiffly though, which I find less preferable myself (I suspect sunflower oil of doing this).

    I did understand several kinds of starch are used to help with a mattifing effect also but there are also reviews of ppl. saying that it started to form flakes on their skin after rubbing accidently.. Somehow I think this might be a thing..

    Is Tego Feel the same as Tegomuls? I live in Europe. I did read about Tegomuls resulting in a more matt finish…

    The dynamic Mini pro looks a bit big for my quantities/wishes. Thanks for posting anyways :). I am amazed how many, more affordable, options are out there. Space saving, more affordable, options… I think I like the OCIS homogeniser head on a Dremel very much. Probably the smaller version of it, of which Helen was talking about… Once I start saying things like this…, the buying usually already is inevitable ;)

    @Pattsi: Thanks… Could you explain when and why you use a overhead stirrer? (for what cosmetic products?) With what kind of blades? Do you use it instead of a homogenizer in cream making also?

    Verry nice tip Helen. That’s exactly what I would like to buy if I decide to do so! Definately still expensive, you are right. But the fact that it’s small and takes up no space….,   it’s a big pro for me… Sweet, big thanks!

    Yeah? Is it that bad? Good thing I checked. I a had a slight suspicion, even expectation ;).Excuse me for my late reply btw

    I am Dutch… So European availability in is important to me. Sending stuff to the US  for repair is expensive.

    I am talking about purely hobby and in quantities purely for one or two person use. Just orienting actually. I don’t even know if I am going to need it. I am too early in this hobby(for me) to even know if I do! But toy’s do attract to me…

    I was actually under the assumtion that stirring generates air bubbles in créme? But that’s not the case I understand now? And are there overhead stirrers on the market that can be transformed (with an extension rotator) into a homogenizer?

    …I think blush/flush are roughly the same thing….

    Ah…, is it?. I obviously didn’t know! Not a native english speaker ::smile:. Anyways…, there was no niamicide in it.

  • @suswang8: there is a very good chance niamicide makes your face blush. I suppose you meant to sqay “blush” isn’t it?

    I have read about it and I experienced it myself when I ingested a niacimide supplement (high dosage for sporters). NEVER ever again. My skin got very very red in several places on my body. It felt incredibly hot. Just like blushing. Man I was scared… I was in the gym when it happened…. It’s a rare side effect of niamicide. People do get it, more locally, after applying it to the skin.. Hope it helps

  • Yeah, I think you are right indeed as it’s pretty waxy stuff… Thanks :)

  • I see what you guy’s are saying. In the end everything is toxic if you absorb/ingest/inhale too much of it. And in this formula there is nothing very alarming to you guy’s? Well OK, that’s good to hear. I have read some things about PEG’s but googled these specific PEG’s listed and I found no real concerning things about them. And you guy’s clearly seem to confirm? Well that’s the easieest outcome for me; then I will for sure keep on using the original one like I have been doing…

    Very helpfull link Perry thanks! Saves a lot of surfing :). Nice

    Hi everyone,
    I am a healthcare worker. I have alway’s had a fascination with chemistry. From time to time, when I find an excuse to play “the chemist” I will do so. But it must serve a purpose. I have a sensitive and dry skin and couldn’t find a skincream that had the right properties AND was unscented. So there my recent journey in cosmetics chemistry begun. Now I like to also make my own shampoo and hairwax. I am a fan of ingredients that are safe and known to be less harmfull. A formulation must still be functional. I like as little ingredients as I can get away with. Just trying t find out what works and what can be left out. Definately just starting to learn. I greet everyone  :)
