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.
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…
