  • Thank you for clearing that up @MarkBroussard and @PhilGeis ! In that case I'll stick with 2) :)
  • Thanks @MarkBroussard, I didn't know the INCI name was common in the USA. I did some searching and came across this: https://www.fda.gov/cosmetics/cosmetics-labeling/cosmetic-ingredient-names (Quote) So this would suggest that 3) is preferable fo…
  • Disclaimer, I have no personal experience formulating sunscreens, so I hope that others will comment. I decided not to bother for now because from what I read, the efficacy of sunscreen formulas is very hard to predict theoretically, and testing fo…
  • Just finishing up watching the event on replay as I couldn't make it on the date. I wanted to say thank you to Perry for the entertaining hosting and all the speakers for the interesting content! I had a great time watching, learned a lot of new thi…
  • Can't answer all the questions, but from my experience I haven't noticed a difference between Coco Glucoside and Caprylyl/Capryl Glucoside in mildness or foam. The main difference that I've seen is that Coco Glucoside is cheaper but Capryl/Caprylyl …
  • Reminds me of the wonderfully weird stearic acid croissant diet: https://fireinabottle.net/introducing-the-croissant-diet/

  • Here's the safety report on triethyl citrate: https://online.personalcarecouncil.org/ctfa-static/online/lists/cir-pdfs/PR590.pdf Generally described as non-irritating, though as always individual experiences may vary.
  • Thinly veiled link-building? A word of caution, the active in these eye drops was developed and is used as a medical treatment for glaucoma by lowering the pressure inside the eyeball. Definitely not a cosmetic.
  • If your product doesn't contain water and there is no risk that water may enter it, then you don't need a preservative. As for why your product did or didn't work, I don't know.
  • What about triethyl citrate as an aluminium-free active? It's in my go-to deodorant.
  • elemental.eu say they have it, according to their website they will ship to the USA for €19.99. :)
  • I just saw a mention of "dry" cocamidopropyl betaine, a quick search showed that it does seem to be available as a powder. No idea about formulating with it though.
  • Which xanthan gum did you use? Cosphaderm X34 shouldn't create a snotty texture. Glucosides do get gummy when they dry out. As for your current batch, no idea what to do with that.
  • I'm partly curious about what I might not know about the benefits of eyebrow sprays, and partly disgusted by the more likely scenario that this is just another useless cosmetic gimmick, generating waste and cluttering people's lives.
  • Why an eyebrow mist?... Yes you would need a solubilizer. Have a look over here: https://www.youtube.com/watch?v=kNbgHvi_lqM Yes you need a preservative, I won't figure out for you which is suitable for this unusual purpose, maybe someone else will.
  • I would also be interested in the difference between SLMI and SCMI. From the little information I've been able to find I believe they are fairly similar but don't really know. I don't know about the slimy consistency, but what I do know is that the…
  • I'm confused, what are the remaining 83% of the formula? Do you mean that you add your powder to water before use so that water then equates 83%? I haven't used your specific surfactants myself, but I have found that each surfactant has a distinct …
  • Do you really need to add water or aloe vera juice? A (possibly whipped) body butter would be much easier to make, no issues with preservation to figure out. If you really wanted to incorporate a water phase you'll also need an emulsifier which is d…
  • The idea that gram-positive bacteria are good is questionable as a blanket statement. There are plenty of pathogenic gram-positive bacteria.Seen as skin infections are most often caused by the gram-positive Staphylococcus aureus, I'd be weary of pot…
  • @ngarayeva001 Do you know of a supplier that sells the vegetable-oil-like fractionated coconut oil? I've been wanting to try it for a while, but haven't been able to find a supplier.
  • @helenhelen Glad to hear you're happy with it! :)
  • It's true I can manage with my bamix and emulsifying attachment right now. However, I have seen that the consistency with a rotor/stator homogenizer can get quite a lot thicker, so I do think it makes sense to get a small homogenizer if the plan is …
  • You may find this interesting: https://blog.euromonitor.com/redefining-the-lipstick-effect-examples-of-recession-proof-categories/ Basically, the thesis is that if people don't have the money to treat themselves with big ticket items, they buy "…
  • I see, thanks for explaining. I do not have an explicit source and instead based that statement on the absence of a reliable source recommending sprays. Very interesting statement you found in the FDA policy, it raises a few potential issues I hadn'…
  • @helenhelen It does seem to be very well received! A modular, serviceable solution from a small manufacturer is right up my street as well. As much as I like the idea of the cordless option, I'd personally go for corded. Short battery life (some say…
  • I definitely understand your reservations about purchasing an item which has a high probability of becoming a wasteful paperweight. One more option I just came across, after thinking I'd already seen every possibility: https://www.usefulstuff.de/pr…
  • I can't comment on that specific homogenizer, though if the 1000mPas maximum viscosity is true I would also be concerned. I've been looking for a similar homogenizer myself, and am currently most interested in this one: https://www.amazon.de/Homoge…
  • Maybe it is this study? https://www.sciencedirect.com/science/article/abs/pii/S0195670113000297
  • We've already discussed this in the other thread, no? The issue that I see is that most spray bottles that consumer hand sanitizer is sold in do not dispense enough to achieve full coverage and sufficient contact time, within a reasonable amount of …
  • Simple process to make soap with lye leached from wood ash: https://www.youtube.com/watch?v=c2Ka0jrOa6A As a generalization, hardwood works better than softwood as it contains more potassium.
