the cold emulsifier i’m using consists of:
-Polyglyceryl-2 Dipolyhydroxystearat
-lauryl glucoside
-glecyrin aqua- Be careful to do patch tests. I tried a cold emulsifier (Emulgin VL75) which is
I think what you have here (the INCI is identical). Sure, it emulsifies really well. But I, and one of my testers, came out in a bountiful crop of pimples (applied to the back of the hand). I am 100% certain it was the emulsifier and I strongly suspect it was the glucoside. -
It has long been known in soaping communities that liquid soap has to be “matured” to allow the insoluble salts to settle out. Then the clear soap is separated. It would make more sense to use the required fatty acids, in my view, rather than the oils.
-
The only soaps that are even moderately soluble at room temperature are potassium laurate, myristate, and oleate, the potassium salt of acids from coconut oil, and the sodium oleate. The other sodium and potassium soaps of the saturated fatty acids require elevated temperatures for solution.
You will note that olive oil contains palmitic, stearic, linoleic, linolenic acids. Do you see them in the above list? No, thought not.

Should i use polysorbate 20 or 80 in it?
- No. Why would you want to do that? Adding something to a shampoo is done for functional reasons. -
Wait for the CAPB to arrive.

You need to use stainless. I would not recommend glass because you’re handling an inflammable material. In fact, I do hope you have a fume cupboard and extractor or you will end up in hospital through inhaling the fumes.

It really depends on what you want to do. If you want to develop a commercial line, then it would be better to base your product on a tried and tested commercial blend and add any marketing ingredients you want. That way you avoid the time consuming and tedious and expensive experiments to develop a custom formula. Our most successful product is a blend; I only have to mix two surfactants, because one of them already is a blend of four ingredients.

For emulsifier, what about this combination?
Beeswax 7.8%+0.2% Borax & Lecithin 1%
NO! It’s out of the dark ages. Use something modern. -
But that would have no antibacterial or keratolytic effect without the SA?
-
The preservative is benzyl benzoate.

Sorry, I just checked but I only have the 8th edition.

Not ‘described by’ me. It was a Dermatology Times article.

I wonder if it’s possible to make traditional soap but bring the pH down with citric or something similar and throw some preservatives in it.
If you try that, you will see why it isn’t possible. The reaction is reversible, the soap splits into free fatty acids and becomes an unpleasant goop. -
Please quote ingredients in percent if you want advice.

Thanks, but … it’s Croda! Here in Mexico Croda are impossible. Huge MOQ, no customer care.

Sure. (This does not apply to the US)
Kill the bacteria: Thyme extract; monolaurin; Tea Tree oil
Stop the inflammation: aloe vera > 20% or more; Calendula extract.
Wound healing: Tepezcohuite extract
Improve the skin, pseudo estrogenic effect: licorice acid -
I’ve only tested with dehydroacetic acid, it split the potassium salt (which was in solution) and precipitated lumps immediately.
-
Use cold process emulsifiers.

In my country I don’t think it is legal to use formaldehyde. It is a known carcinogen.

@Bios, frankly, you appear to lack the knowledge base required for formulating this kind of product. Copper peptides are about as similar to copper chloride as pine bark extract is to coal tar. You would need not only to source the peptides - which will NOT be cheap - but also to store, handle, and formulate in such a way as to preserve their desired properties. How much formulation experience do you have? Any experience with peptides?
-
Glabridin is available from China.
-
Why would you want to do this? I have not seen any information about copper benefiting skin - except for copper peptides, which is a completely different thing. Copper chloride is a blue-green compound that will probably stain the skin. Do you have any studies to quote about this? The only reason I can think of is if you are designing a medical product to deal with skin diseases such as impetigo.

^^^^ Exactly.
If you have the pure acid or its salt, well, it’s obvious. Try doing a 100:1 dilution and tasting it. You will know.
The 12% root is equally obvious. It is a yellow-brown powder with an intensely sweet licorice flavor. The saponins it contains appear to be synergistic with the surfactants I use, it does not settle out, but rather, makes the most amazing metallic effects with cold pearl, and its hair conditioning ability is remarkable. -
If you want the antibacterial benefits, do not use coconut oil, use lauricidin. It’s easy to use, just treat it like you would cetyl alcohol.
