I agree with Bill. You won’t ever get this to work. Either go to a synthetic detergent (syndet) bar or make soap without skin lighteners. There is zero evidence that skin lighteners will work in soap anyway - I’m reasonably certain that they have to be applied to skin in a lotion and left on for a considerable length of time in order to work at all.

I’m feeling helpful, so I will pass on some information that I found on the web. Not too hard, just search for mango butter manufacturing process.
As far as I can tell, Mango Butter is the high-melt-point fraction of Mango Kernel Extract. Mango Oil is what’s left behind after you refine the Mango Butter out of the extract. So, saying you want the butter and not the oil is using the wrong terminology. Perhaps you meant that you want the extract?
Wikipedia has some useful information: https://en.wikipedia.org/wiki/Mango_oil
And there’s this:

OTC Sunscreen actives are always +/- 10% of the Active amount. The assays aren’t that accurate, so you need every bit of that room.
-
I checked, and there’s actually a bunch of information on how to do this already on the internet. Basically, you have to get the kernel out of the shell, then either cold-press or solvent-extract the oil from the kernel, which is about 14-20% oil.
How large a scale are you planning?

We all have experience using variable speed overhead mixers with a heat source below the mixing container - it’s the standard lab configuration for cosmetics.
Determining how your procedure should be run is best determined with experimentation. There are some shampoo formulations that can be produced by dumping everything in at once, then stirring. Some formulas need heating on top of that. Other formulas need two separate phases mixed together.
You will want to start by using a sample formulation from a reputable website, and follow the manufacturing directions PRECISELY. Once you’ve made a successful batch that way, you can start changing things around.
-
You’re going to need to pay a consultant for that. Good Luck!
-
This would be a drug/pharmaceutical product. I’m sorry, but I can’t help with this sort of thing - the potential liability is much too high.
Just about the only thing I can say is that this is a dangerous product to experiment with, and I strongly suggest that you not do it at all.
-
Purify it to what end? If you want to grind them and use them as exfoliants, probably boiling them for a few hours would work.
If you’re trying to make some kind of extract, crushing them and then boiling/extracting in hot water might be a good first step also. After that, it gets complicated.
-
I don’t want anyone to think I didn’t agree with Bill either. The best way to make most products on a small scale is with a stirrer above the batch and a hotplate below it.
-
From their website, it looks like they’ve already discontinued the 250W model.
The data logger program would be quite valuable if you are going to scale up in an advanced facility that has engineers capable of interpreting the results and applying them to their larger-scale machinery. It would also be helpful if you were making pharmaceuticals of any kind, since regulators love documentation. Otherwise, I’d consider it a very expensive toy.
-
This is really about your future needs. The 1hp (750W) motor is 3 times as powerful as the 250W motor. You may not need that extra power now, but it’s possible you will in the future. Also, the more powerful motor will not only allow you to move more viscous material, it will also allow you to move larger volumes of material. And, all things being equal, a larger motor with more power working at a lower percentage of its capacity is usually much more reliable than a smaller motor with less power working at a high percentage of its capacity - that should translate into a greatly increased lifespan for the L5M-A.
Finally, it looks like Silverson no longer makes the L5M model at all, so if you buy one, you’d be buying a discontinued model, which I wouldn’t recommend, even if it is cheaper.

You need to realize where the weak point in using a magnetic stirrer is - it’s the connection between the magnet attached to the motor, and the magnetic stir bar doing the stirring. Using an overhead stirrer eliminates that weak point.
There are some magnetic stirrers specifically designed to somewhat overcome this problem, but they require specialized stir bars made with high magnetic strength rare-earth magnets. If you have bunches of money, look at IKA:

If you have less money to spend, you can go outside the scientific area and get acceptable performance, but without the bells and whistles. Heating will need to be done seperately:

Not sure of the prices here:

No, there is no correlation at all. The shelf life of any chemical is for that chemical at 100% only.

Pemulen TR-1 is only sold commercially by Lubrizol:
https://www.lubrizol.com/PersonalCare/Products/Pemulen/PemulenTR-1.html but you can get small amounts at The Personal Formulator http://www.personalformulator.com/wvss/product_info.php?products_id=1010 -
Try adding some Pemulen to your water phase before emulsification, and then neutralizing it after emulsification. You may find you need to reduce your Cetyl Alcohol a bit to compensate for the increased viscosity you get from the pemulen.

I’m stumped, personally. Anyone else have any ideas?
As a result, I would fall back on what I always do whenever calculations are useless and/or incomprehensible (which is often).
Determine the correct value experimentally. Just make several batches with increasing levels of caustic, check the pH, and you have your answer.
As a byproduct of this discussion, I just realized why very many of the home crafters I’ve talked to are so overly hung-up on calculating things - it’s because it works very well for soap.
-
Just an ordinary light microscope should do.
Clay will not breed microbes in anhydrous products. No water = no growth. Concentration of clay isn’t an issue, unless it caries a lot of water in with it - dry powdered clay typically has little to no water. Mold is a problem whether you have clay or not.
-
which dow corning emulsifiers are available to you?
-
Love it.
-
I appreciate that you’d like help, but you haven’t actually asked a question. What specifically do you need help with?
-
OK, I’m giggling. It’s awful, but really dark humor. Healthy hair burns at Just over 450F, (actually 233C/451.4F). I’m just imagining someone taking that claim seriously…
I know, I’m a horrible person before I’ve had enough coffee.
-
Let us know how that works out. Now you have me really curious.
-
Have you looked at @Perry’s course about this?

It’s not like you only get one chance at investors. I’m sure it’s a learning experience. And if you’re the kind of charismatic, outgoing person who can charm an investor into working with you just from an idea about starting a line, great. I would personally be way too worried about all the other people competing for the same money to even try that. I’d have to feel that my plans and presentations were as good as I could make them before I could have the confidence to ask for money.
So, I realize that I’m probably the wrong person to ask for advice on this. Especially since, as far as I know, there is no way to contact investors unless you already know them.
-
I’m very risk-adverse, so if I was going to do this, not only would I have a credible business plan and sales/marketing plan in place, but I’d have the entire line mapped out, right down to the product types, all the shades, prototypes for the shades and product types, label/packaging design, and even the display units - with as many concept drawing as possible. Even plans for expansion, and contingency plans for not getting as much seed money as I’d hoped for.
All this would be in place before I ever talked to an investor - because otherwise, you’re asking an investor to trust you enough to let you design the line after he’s already paid for it - and that’s a very big ask for someone with zero experience starting lines. You need a well-polished presentation, also.
This is months and months of full-time work, but I seriously doubt you’ll find anyone to give you money otherwise.
