I ground it and sieved it until it was like talcum powder. Then I made a 10% by weight mixture with water. After about 10 minutes 90% had fallen to the bottom making a thick paste.
Then I blended it using the high shear blender for ages.
Same result.
Obviously this isn’t good enough. The problem is I really can’t see any way to make sure it stays suspended without using a carbomer type system such as Aqua SF-1 and I have already decided ages ago that carbomers and shampoo are things I do not like to put together. -
Pseudomonas: “Infections range from mild external ones (affecting the ear or hair follicles) to serious internal infections (affecting the lungs, bloodstream …”
The batch should be junked immediately. That’s my opinion. -
13% essential oil of peppermint? That is a really high amount. Really?

I can bring it in, but only via post, which “usually” works for quantities up to a couple of kilos. Any method other than post fails at the customs. It’s like a Guild system from the 18th century! So for instance I don’t mind importing things like glycrrhizic acid from China which I use at 0.2%, but I think oatmeal isn’t sufficiently high value. However I live in a city that’s full of industries that have mills, it is not inconceivable I could have 100Kg milled if such a product took off. But then I’d have other problems to worry about.
Anyway I will do a product development on it and keep the thread updated. -
The only people who have bath tubs are the rich, who have Jacuzzis. This is one of the reasons why I haven’t emulated Lush (our business plan is similar) with their bath-bombs. I don’t want to risk customers calling us and saying “your bath bomb ruined our Jacuzzi”!
I just made about 200 grams of it in the spice grinder. Ground the hell out of it. After sieving, I tested it and obtained about 90% ‘milk’ dispersion and about 10% tiny particles that settle at the bottom.
Now I have to think about producing it.Thoughts:
1. It will act as a thickener probably, so I may need to adjust the viscosity by decreasing the thickener (a good thing, Glucamate VLT is expensive)
2. Since the shampoo won’t be clear any more I had better make it pearlescent which is hot process.
3. If hot process, presumably I need to avoid cooking the oats, so it’s going to be added during cool-down phase I assume? <50C? -
It is available here through Amazon.mx but the price is wildly excessive, $41! I checked pharmacy outlets for it. - No, doesn’t appear to be stocked. One possible reason is that hardly anyone takes a bath here in Mexico, showers only.

Aha! Thank you! I have Gluadin W40 in my lab supplies, I use it in the conditioner, but not the WLM. I do have a spice grinder though. Bringing things in from the USA takes time and sometimes fails, I’ll try to reduce it fine enough.

The problem with Lincoln is that it would be an import item and thus, problematic.

With some thought and glass tubing it might be possible to design one. An old geezer called Archimedes is relevant. It’s physics.
Please disregard my idea about boiling off the oxygen (unless you are doing it in the open air) because filling your lab with oxygen is not a good idea. -
Do you mean measure the volumetric concentration of H2O2? It occurs to me that you could boil say 250 grams of it in a reflux setup (Vertically mounted Liebig condenser) to remove the excess oxygen. What remains is H2O. Then weigh the remaining water, and do the Math. I’m not absolutely sure that boiling will remove all of the extra oxygen, I’d have to check.

You can find it here. It may be more than you were looking for (grin)

We are just relaunching after having our original brand stolen from under us, the new site is http://www.pearandpeach.com but it is in its early stages. However our old brand, Belassi, still has its Facebook page at https://www.facebook.com/belassimx/ - at the moment we are working with the designers to create the new label designs etc.

Well . . . having this hand problem several years ago as a result of buying some cheap dish washing liquid, I bought a tube of shea butter hand cream from Evelyn and Crabtree and it worked so well, I copied it and decided to start my own personal care company.

If you want something non-greasy use a silicone as an occlusive (barrier layer). Plenty of humectants such as glycerine, sorbitol. Aloe vera as an anti-inflammatory.

It’s really a paint question. A paint technologist will be far better at answering questions concerning paint. Nail polish is very very similar to car paint. The glitter and so forth is identical to the products of Metalflake(tm) used to paint custom cars.

I posted a link to an exhaustive article about surfactants a while ago.

You need a paint technology chemist.

If you altered the pH to 7 by adding an acid such as citric acid, what you have is snot mixed with SLES. If you try to reduce the pH of saponified oils by adding an acid, it decomposes. I cannot imagine why anyone would want to make a mix of natural and synthetic surfactants, it defeats the purpose of both.

It makes me realise that I don’t know much about any of these different substances
I guess my next step is to find out the MOQs and prices. I know that the MOQ with Inolex is usually pretty large. I’ve decided to reformulate all the creams, there is no point in doing it one at a time. I already did one today, our most expensive one. It came out better than before but I will have to put a few to one side and begin shelf life testing. I’m hoping it will be OK. I set the pH to 4.5 (was 5.5), increased glycerin to 3% and added 0.2% EDTA. -
Thank you all for your comments, so far! As a result I have already knocked out 4 of the possibles. I didn’t know phenethyl alcohol smelt like roses - I’d rather add the fragrances we prefer. And I was unaware of the problem with isothiazolinones. Any more comments will be very welcome.
-
Thanks. Pity they don’t provide a list of their exhibitors as is normal.
-
Very clear, thank you. Assuming our efforts to locate a permanent supply are successful, I think we’ll move several products to this style.
-
I imagine you can use a much lower level of preservative?
-
Oh. So there’s a plastic base, rigid I imagine, that progressively moves up and into the cylindrical body, as more product is dispensed? Is that it? The seal must work pretty well.
