I just had a cold process emulsion fail using Caprylyl Glycol (and) Phenoxyethanol (and) Hexylene Glycol.  First one in two years.  Next time I'll add post post emulsion.  I sorta stupidly believed a guideline that I suspected was n…
  • If you have to have high electrolyte content and want a serum or creamy serum you might consider a combination of Seppic's SepiMax Zen (Polyacrylate Crosspolymer-6) maybe at at 0.5% with Sepinov EMT-10 (Hydroxyethyl Acrylate/Sodium Acryloyldimethyl …
  • @MarkBroussard, thank you. That was helpful to me. And now, I have worked up the courage to ask what may well be a dumb and obvious question to you guys. I bought a used Sorvall Omni Mixer/Homogenizer. I found instructions how to dissemble and…
  • Realize Beauty very recently did a piece on chelating agents. She is a big fan of sodium phytate. I don't recall her mentioning anything about pigments but she did point out cost of the ingredient. You might try adding a question on her post.
  • @Perry, thanks for doing this. Looking forward to it.
  • @Perry Impressively fair minded and I would be grateful for the same treatment in those shoes.
  • Thank you, @MarkBroussard and @Perry.  Nice to know I am learning and can trust my judgement a little.   @MarkBroussard, that is exactly what my thoughts were about the "fractionally distilled", simply the extraction method that had nothin…
  • Recently, I've come across two vendors selling toners and there are no preservatives listed.  One was nothing but rosemary hydrosol and the latest is aloe based.  I inquired about the aloe based product and the first response was that they needed no…
  • Humbled again. I created one for my own use but never thought to have the water percentage self adjusting nor did I add the cost columns. @bobzchemist - I hope the repeated humbling keeps me from reaching the peak of Mt. Stupid. How does your spr…
  • Carbomer again, eh? Thanks for all the comments on the other thread. I've played around with the sodium carbomer and hope to find time this w/e to try 940. I had some very nice results with non ionic emulsifiers and even with Rita/Eco/NutraMulse.…
  • Thank you to all. @bobzchemist, I hope one day I can pose a question in that last "Best" format. In the meantime, I will always do my best to be respectful of the experience here and post as much detail as possible. But, sometimes I a…
  • I've read a number of posts that are very demanding and rude and have been surprised by it. I can understand how the experts would be offended and not interested in assisting. On the other hand, I am keenly aware most of you are much more knowledg…
  • @bobzchemist Thank you for pointing out this is derived from berries and not tree nuts. I used the link you provided, read the info, and learned this has a high HLB. The company states it would be useful in emulsification including oil in water…
  • Jane, Sorry to derail your question with my lecithin response. If you're at all interested in the perspective of a non-chemist, I'd say there are some homecrafters who will never budge from their stance of "all natural" ingredients. Jus…
  • Gazelle, I'm not one of the scientists here but in a very early formula I made I used lecithin as the emulsifier. I used a formula from a book I had bought. Last one I made from that book. I did not care for the end result. The skin feel was un…
  • Hi, I'm Nanette and I'm new to cosmetic formulating. I've been spending quite a bit of time reading through everyone's posts, learning a lot, and envying many of your science backgrounds. I'll admit to a certain amount of trepidation introducing m…
