Actually I use many products with plant based Omegas. Firstly there is an overwhelming demand for vegan products in the market I work in (smaller start-ups). A fish product would get washed out for this reason.
AAK makes a plant based Omega 3/6 product that is quite affordable and I currently have a product in production. If you are looking for just Omega 3’s predominantly many will use Chia Seed Oil to provide this benefit.

@DavidW is probably your best resource for this question. He is out of Florida and well versed in the Regs.

I only posted the article because you implied that Sodium Hyaluronate decreases TEWL as its primary mechanism of action.
In addition since we are discussing moisturization it provides a baseline for the newer people following the conversation.

Belassi is correct. However with the movement towards more “natural” products I encounter more and more people trying to use these products as a Pomade. The “natural” products fall far short of the more traditional products. This is arguably an area where “natural” needs to take a back seat to performance.

Pumice is traditionally a darker colored abrasive volcanic rock. The white grade is usually grey to off white. I worked on a project with the material years ago. We got more whitening by reducing the initial concentration and adding some Zinc oxide. In the end we further reduced the pumice as it can be more abrasive than some other materials and will cause more exforiation (scraping).

Sorry for the weird text, that is just how it pasted. Generally Sodium Hyaluronate is considered a humectent although it is also an important part of the NMF as well. If you read up a little you will find that mimicing the NMF can be an effective tool in moisturization.

While it arguably could have some effect on TEWL, this is hardly the primary mechanism of action of Hyaluronic acid.
Generally t acts to draw water into the skin. Current thought is that TEWL is improved over a period of time as the NMF is restored. It is fairly involved and many other chemicals contribute just as importantly to the NMF.

Really never said it was hard or complicated, just not something to take lightly or to attempt without some real study. Perry has a webinar coming up this week for anyone looking to get a good overall picture of the topic.

Why not obtain and use a commercially available 30% solution of SLS instead?
-
Just a quick addition. You decided on the lowest concentration of preservative. As Makingskincare also points out there are many issues. In only the best of conditions (low water content, no difficult to preserve ingredients, packaging, etc.) would you go this low. While I know many due to safety concerns like to use a low level, keep in mind that an insufficiently preserved product is actually MORE dangerous to your clients than any chemical ever will be.
If you look at MakingSkincare’s website, she has a pretty good initial review of preservation and preservatives. I only say initial review because as I said preservation is constantly evolving, especially in regard to naturally compliant products and todays expert would be behind tomorrow if he didn’t stay current.

Too many to mention! What region are you looking in?

It is not that simple. Selecting a preservative really takes a big picture approach. What is the final pH? Is it a leave-on or rinse-off product. Packaging is a factor as well.
In the end the only way to get a final definitive answer is to get it tested. Bottom line.
Lastly, if you are going to make Cosmetics you are hardly done researching this preservative or preservation as a whole. I read 3 Journals a month from cover to cover and I would estimate 30% of what I read about is preservatives.
To show how big picture your approach needs to be, check out this website. It is run by a distributor so they recommend their products but in the end you can see how many factors affect this process.
To be truly effective in crafting Cosmetics effectively and safely you MUST put in the time to learn and continue to sharpen this knowledge. Preservation is not an area to take lightly.

Lots of people here are happy to help, but as many will say you still will need to engage in the basic research. It will lead you to a better understanding of the subject matter. That said; try this link.

I just ask since I had a client who sold a product at such a low pH. What is interesting is at that low of a pH many of the actives could be denatured. Rather than an emulsion you might just be making a Ceviche. In his case he sold it on Amazon. Several years later I learned he lost a lot of money in a Product liability suit when it caused scarring. Hence the 3.5 pH limit.

So out of curiosity, you know this and it is a Professional product or you know this and are forging ahed?

Works now.

For me the audio dropped off at 0:37.

Soliance has had a similar product for years as well (Vegetan FL Creation).

Where did you find a water soluble Salicylic acid powder? I am not doubting you. It is just that usually Salicylic acid presents many issues regarding using the proper solvent and generally water solubility is unfavorable. I use a lot of an encapsulated version (Salspheres from Salvona) but it is much more expensive than Salicylic acid and a solvent.
-
Would have to see the Formula. Keep in mind that HEC is not an emulsifier but rather a rheology agent.

Check with Bobzchemist. I believe that the company that he works with does this type of work.

On Ebay you can get some Silverson’s which are the gold standard. You are right to be careful with any brands that you don’t recognize.

You may want to consider sourcing out a used Homogenizer at first either on EBay, LabX or a similar website. If you look hard you will see some deals. A new piece of equipment can be pricy and quite an investment. I have spoken with several people who have bought less expensive “imported” homogenizers. In general they have had bad experiences as the equipment is difficult to repair and difficult to get replacement parts if needed.
