On the other post you were asking about Fragrance, use peppermint will give a nice fresh smell. As for the formulation, it has already been stated, avoid mixing bases and acids.

@MarkBroussard thanks for the link
@Perry agree

As chemist I do consider any molecule as a chemical, most people think: Chemical = Man made no? as Natural is made by mother nature…

Hello might sound stupid but, if you buy the HMW, blend is dry for 10-20-30min…. you will get you LMW no? just need a lab to give you the MW distribution I would think (GPC)…  this does not answer your question but could be a cheap alternative to so called nano product

Hello I have a limited experience but sounds like the guar did not swell properly! Are you sure that you or your staff are following the same procedure?
I found the use of some 4-5% glycerol helps to suspend the guar before the addition of H2O.

Tks @Microformulation

thanks, at the moment I am reading more on testings/assays…

Out of curiosity I look at the supermarket, and yes I agree this is the general idea, sulfate free, pH around 7, but not much science regarding the effect on the skin, eyes…. of coco glucoside for example or Cocamidopropyl Betaine…

Hello
I could create a new topic I guess but I thought I would ask here as we are discussing tear free: How can we back up the claim “tear free”? All well and good to say it but…. any science out there…? Thanks

[Max]

hello I had some success with xanthan gum, you can get a very clean gum that gives you a clear gel around 0.5/0.6%

[Max]

🙂 Thanks

Hello, I am not a fan of Wiki, but well sometime it is a start….

@Belassi what do you mean but “Protein additions”?

[Max]

@Biochemist not really, any home brew store will have some, they look like a belt that goes around the drum. 

[Max]

it all comes to the $.

a 200L drum, second hand will cost you $10, you get a drill and a paddle and you are in business I guess. To heat a you can get 2 or 3 heating units used for home brew… they can heat your mix to 40 plus degrees…

@ozgirl cool Brisbane here

[Max]

fair points thanks, I mentioned it mostly for general interest

BTW Ozgirl, where are you based?

[Max]

thanks for the feedback, we use an outside lab for PET test  
in regards of the oil-based preservatives, well might work in some cases, never know before you try I guess…

Now that’s an impressive database :smiley:

Thanks a lot for the link Perry

[Max]

Gday!
try also, Labtek, Labgear, some good new/second hand at Science essentials.
To be honest Ebay is also a good/cheap option for basic equipment.

[Max]

No  idea about the patent protection. Now yes they are not as effective but stable… you have to find a win/win solution I guess

[Max]

Hello, I used to make Retinol/Retinal… Not my favorite, as mentioned, Retinol is very unstable. As recommanded earlier, I would use, if possible a precursor like Retinol Acetate …
