@Bill_Toge I am working on a 10% azelaic acid emulsion, using sepimax zen as the main emulsifier/gelling agents. I noticed you had success with butyloctyl salicylate as the solvent. What would be the appropriate usage rate to solubilize the 10% azel…

Thank you! Aloha to you as well.

@Graillotion I have the AVC and am ready to experiment next week! One question I have is about pH adjusting when using AVC. I have seen other electrolyte-sensitive polymers mention pH adjusting can negatively affect viscosity. How are you pH adjusti…
-
@Graillotion @jemolian Looks like I have some experimenting to do. Thank you both!
-
@Graillotion Thank you! I might just convince the client to remove the electrolyte offender from the formula (not doing much of anything) Batch a sample with AVC (no electrolyte) and without the AVC (with electrolyte and different polymer). I am de…

Brilliant. I'll test it out. Thank you @MarkBroussard !

@MarkBroussard I think I have asked this before, but I can't find the thread. Have you tried any of the dimethicone alternatives like the LexFeel N series? Do you find they also have some anti-soaping properties? Just trying to source materials for …

@Perry fascinating. Makes sense. Thank you!

Noted! Thank you, @MarkBroussard

I do not have a sample of this (yet) but the client says it has no crystals after sitting for months. I also question the SA content given the location on the IL (have not seen CoQ10 used at 2%+) but it is marketed as 2% all over the website.

@MarkBroussard :D touché

Rubies, diamonds, and crystals in your products provide "healing energy" to the skin. Also, there is a brand that sells "harmonized water". Water that is "infused with scalar waves" - leads to the water molecules "…

@Syl seems like no industry is immune to drama! Thanks for sharing.

@PhilGeis thanks for that link! Fascinating information. Do you happen to know if AMT owns Formulator Sample Shop? They have a link to them at the bottom of the website, they are located in the same city in N. Carolina, and FSS pushes a lot of the A…

Happy Birthday, Perry!

@MarkBroussard do you happen to have a preferred vendor for it?

Thank you! @MarkBroussard

@ketchito @Graillotion sorry for the delayed response! (on vacation). I don't have images of my retains until I get back, to show the darkening. This is a product for a device manufacturer client, where the solution is being applied to the skin t…

@chemicalmatt brilliant. Thank you for the insight and suggestions!
-
@natzam44 As suspected. Thank you! The heating question is regarding post-application on the hair, not during formulation. It seems a lot of the polymers, after application to the hair, require some sort of heat source to "activate" the fi…

@pattsi Yes, that is correct about the "R" name... ;) The client doesn't want to avoid preservatives. At all. The product was just presented to me and I saw how ridiculous it was and I explained that to her.

@Perry :D Truth

@Pharma Right? The "claim" is that they are "biologically active" and highly bioavailable, especially those that are acetylated or have fatty acid moieties added, and are of low molecular weight. Of course, marketing fuels most o…

It would vary per peptide-complex blend. You would need to ask for the compositional breakdown from the manufacturer. I do find brands tend to mislead in marketing when it comes to peptides. For instance, Matrixyl 3000 (INCI: Glycerin, Water, But…

@Rockstargirl the only available data on HPR comes directly from Grant, the manufacturer. I don't think any independent, peer-reviewed studies exist.
-
@Pharma great question! I was as confused as you are. When I read the Veegum data, the suggested usage rate was much higher than found in this formula. My guess is that it was added as a stabilizer, but even then the client says the current formula…
-
@ariepfadli thank you!

@Pharma thank you

@Abdullah I believe that happens in-vivo with the triglycerides in the follicle sebum, but the question is if topically applied triglycerides (plant oils) get broken down into the FFA's when applied. @jemolian great article by Michelle! She seems …
-
@Pharma thank you for saying this! I see far too many people claiming benefits of plant lipids due to the FA content, but we know that very few FA's are free within the oil, and most are bound in triglyceride form. For instance, there are data s…
