Ethyl Lauroyl Arginate HCl (aka… LAE) …. preservative.
Just had this one come across my path the other day. Had not really heard of it before. Some of the mfg’s have such glowing propaganda….I think you could heat a home in Wisconsin this winter with the marketing material. Then another one…showed material that basically it was all but worthless without a chelate. So, two very different outlooks on the same product.
Naturally I am very skeptical, as it is trying to be a one and done…cure all for ‘greenkind’. 😆
What are your thoughts Dr Phil?
One of the trade names is ‘Sepicide™ G’…. the one you could heat your home with. Whereas Sino Lion….was much more along the lines of….better bolster the $hit out of this.
What about as a deo active? (Vs preservative)
Aloha.

I’ve heard of it but have no experience with this one. Recall it another fake “natural” but is GRAS. Perhaps it’s like polylysine - a cationic.
-
Yes….in the marketing, they do mention cationic.
What does that mean in the scope of preservation?

Perhaps like quats - destabilizes membranes and transport. Quats disinfectant work great in testing, pseudomonads can contaminate in practice.

I came here searching for more information on LAE as I explore uses for the 2 kg batch I now have on hand 😮💨and read this and thought “I feel like that’s D**g, and I feel like this is based on our conversation” lol. <div>From what I’ve learned LAE’s efficacy has everything to do with its cationic nature. It prevents the bugs from doing their thing and they end up dying. Your advice on the booster was spot on. From what I understand and have read in studies (and I am not a chemist, which is why I hang out here to learn from them) without the booster the LAE gets tied up clinging to other things and can’t attack the germs so they proliferate. </div><div>
</div><div>My testing items have held up beautifully and one of my testers showed me how after just a week her acne has cleared up significantly. I actually stumbled upon something about using it in deodorant. I will find it for you and post it. </div><div>
</div><div>Thank you again for all your help. If you would like a small sample of LAE to experiment with let me know and I will gladly share. It’s the least I can do for the kindness you have shown me and many others in sharing your knowledge. </div>-
Here is a study on the antibacterial mechanism: https://www.sciencedirect.com/science/article/pii/S002364382200384X

😆 You think you know who I am eh? 😄
I asked Valerie G about it….and she was also a little skeptical….. considering it more of a food grade preservative. And yes….keep the anionics…to an absolute bare minimum! However…that being said she did send me this file…see attached.
I cannot look at a sample product….and tell you if it is preserved or not. PET is the best method for this. Also, good to have in your files…..should legal issues arise…..it is the first thing they’ll ask for.
So, what I am interested in…..is if you do PET…I would love to see the results!
You know how to get ahold of me. 😂
Aloha.

Thanks I too look forward to anyone’s experience.
Don’t get too excited by the supplier’s article.

-
Did you ever send an emulsion off for PET? Still curious to see the results.
Aloha.

Used ethyl ester as skin penetration enhancer:lauroyl hydrophobe may increase efficacy for that application but would need to do Franz cell to verify.No exp.on preservation but cationic salt may work similar to BAC as suggested:mic not worth much.Maybe suppliers should use AOAC use dilution for kill times on specific organisms??
