@Cafe33, agreed, I have a Uline 3Kg scale (0.1g increments) that came with two 500g calibration weights, plastic cover, and power supply, and it’s the scale I use most frequently. Really good item.

   Wait until we get the swimming pool heater sorted out…

Normal behaviour actually. You will need to experiment with cooling methods.

The glucoside is a non-ionic surfactant and the cocopolyamine is a pseudo-cationic conditioner. We use that in all our shampoos actually (Polyquart H81) at 1%, it gives a ‘volumising’ effect and makes the hair more manageable. PEG 150 distearate is just a thickener.
PEG-6 CAPRYLIC/ CAPRIC GLYCERIDES acts like a water soluble oil that doesn’t depress foam too much, it’s an emollient / refatting agent.
SODIUM LAUROYL OAT AMINO ACIDS is a gentle anionic surfactant.
All the rest is of no consequence, it’s claims ingredients, pH adjusters, buffering, fragrance and preservative.
I would say it should not be too difficult to duplicate this product but it will not be cheap to make.

soapberry and xanthan gum … sounds horrible, I can just imagine the vile snotty sensorials.

[belassi]

“No detergent” eh?
What do you think CAPRYLYL/CAPRYL GLUCOSIDE is? And this? PEG-15 COCOPOLYAMINE
Hahaha!

I use 70% ethanol but I use safety precautions and don’t hang around to get drunk by inhaling it.

1. Do you have a brand?
2. Do you have a logo?
I see so many going about this backwards. First, do market research. Will the products sell? Will there be a demand?
Please take the benefit of my advice. When I began this eight years ago I was like you, except that I have enough background teaching chemistry to be very familiar with using a lab.
I flung myself into developing products and tested them on all and sundry. One after another. Soon I had quite a range of skin creams, gels, shampoos and conditioner. I invented a brand, Belassi. We exhibited our line before we registered the brand, and someone immediately registered it and stole it.
We began the branding process again with a new brand. Successfully. It cost money and time.
And now? How many of all those products still sell enough to cover the expense of stocking them?
TWO products. One shampoo, and one anti-aging cream. That’s what our customers buy.
Think about it.

[belassi]

Way too many preservatives. I use just 0.4% sodium benzoate at pH 5.0 to preserve a shampoo that’s based on percolated coffee. (You have no doubt seen how mould grows on coffee if it’s left for a few days?) I recently discovered a half-used bottle my daughter left behind 8 months ago. Still perfect.
aloe vera juice in shampoo? waste of money.
Lamesoft PO65? 3% is too much. Use 1%.
Oils 2%? Get rid of them, terrible for cleaning and also viscosity.
EO at 1%? Too much. Use 0.4%
Cocamide MEA at 1.25% will enhance foam and viscosity.
There is an excellent liquid thickener, I use it, and it enhances preservation too since it has propanediol. Glucamate VLT. But you will not like the price.

[belassi]

Oh I see. I thought it was a skin cream, I didn’t know it was a mask. I should have realised, with the clay. There’s no bentonite in there is there? That’s bad for redness.

Moving house as well, 30KM.  We’ve bought a lovely old stone built cottage in 1,750 sq m of ground. But I need to build the new lab. At least I will be able to custom design it, with plenty of power points, storage, and so on. 

[belassi]

In order of probability:
1. niacinamide (known for this effect)
2. potassium sorbate
3. phenoxyethanol

And why are you using CAPB in a leave-on skin product?

[belassi]

Gracias! Tengo que construir mi nuevo laboratorio.

[belassi]

Thanks.
We are moving to a small town south of Monterrey, called Santiago. It’s a “pueblo magico”.

Carbopol 94o type will not work at that pH level. @thuy9197 is correct to use SF1. Though, I doubt such a low % will work.
You can find the correct quantity of KOH from various online calculators, eg soapcalc.net

[belassi]

Sorbitol has quite an effect. Try this:
Take a small sticking plaster and coat the pad with sorbitol. Then stick it to your skin. Take a look after a couple of hours.

[belassi]

1.5% is way too high.

[belassi]

I have the feeling that their MOQ was like, “Do you have a discharge bay for our tanker truck?”

[belassi]

I second @Gunther. If you want sulphate free, there are so many combinations and different surfactants it could take a lifetime to come up with what you deem acceptable. It took me, oh, a year I think, to come up with my first, and it needed thickening with a very expensive thickener. It was ok but it was too expensive. Then I spent another six months experimenting with things like Plantaren LGC Sorb, Betaine, sodium cocoamphoacetate … the list goes on.
None of this mattered in the end. The ammonium sulphate based blend and CAPB so far outperformed everything else, it became the product my customers want, and when I used it as a base for novelty shampoos such as tea tree, coffee, and so forth, even more so.

The process of mixing in a machine induces friction between the particles. There is an energy input. I think it’s quite possible that the mechanical mixing energy is causing a chemical reaction between two or more of the components.

[belassi]

Just to upset all of you, I buy the more exotic materials direct from China, by post, and have never had a problem.

[belassi]

Yes, that’s right, I remember now. Corbion.

[belassi]

This shouldn’t really be a problem, as Perry said. Use a paddle style mixer, mix at low rpm and keep the paddle well below the surface. Then simply let the shampoo rest for a few hours, overnight if necessary, prior to pouring. The foam will have subsided.

@Zink:
If you want to try Dipotassium Glycyrrhizate, I could send you a small quantity of the acid. I stock pure Glycyrrhizic Acid. You can easily convert it to the dipotassium salt by titration with KOH. I tend to use a lot more of the yellow-brown 12% liquorice powder extract (in shampoo).
