Cocamide-DEA and if it’s a hair product Polyquat 10.

The most commonly used stabiliser is xantham. I personally prefer either siligel or carbomer.

You are waisting materals. Up cetyl alcohol to 20-25% and 15% of emulsifier will be enough. Cetyl is coemulsifier. I make a generic scrub for personal use with 20% of stearic acid, 10% of cetearyl alcohol, 5% of PEG-40 HCO and 10% of some diy emulsifier (because I don’t want to waste good materials on this product). Oils qs. Work well.
-
They don’t have to be W/O. Any generic emulsifier like Polawax should work because the purpose of emulsifier in such a product is to help water to rinse the oil off. But as Perry mentioned it’s impossible to give a reasonable answer without seeing a formula. My only unintelligent guess is that you are not using enough emulsifier.

I am pretty sure it’s a bias, but what surprises me is that many people formulate without Excel. I can’t imagine how is it even possible.

This one is better and earier to work with than wrinkleblur

Analise commercial products with oils. You will notice that oils are very close to 1% line. It is just a marketing trick, because consumer thinks that oils are good for hair.
-
Again, it might be contrintuitive but oils in shampoos don’t do what people normally expect. They don’t make hair smoother but just supress lather and compromise stability. The feeling that you want is achieved by using right surfactants and conditioners. Add 2% of honeyquat and you will see the difference. And don’t add any glucosides they tangle hair.
-
Is SLMI anionic? If so, don’t use cetrimonium. 2% of polyquat 7 should work. And don’t use more than 5% of decyl glucoside (you can skip it at all). Silicones are nice but you can make a good product without silicones if use cationics.

Germaben II -very low odor, doesn’t destabilize formulas (as many preservatives do), very efficient (probably one of the most efficient in the market), watersoluble which makes it work with surfactants, o/w (but not w/o) lotions, serums and clear gels. It’s transparent and colorless and doesn’t compromise the look of the final product. It will work for the pH range you mentioned. One problem, it’s not approved by any natural standard. But it’s good to know about it in case you want to make something for personal use (or friends and family) and want it to have long shelf life.
-
You will need a very strong preservative system with such approch. Hydrosols and infusions are bug food. I would recommend skipping it and adding a tiny amount of some plant extract for claims, unless you are willing to use parabens or diazodilinyl urea. Your hair will feel tangled without conditioning ingredients. Oil isn’t a conditioning ingredient. You need cationic polymers (or cetrimonium chloride if the formula is non-ionic). I am not aware of the existence of natural conditioners. Also natural isn’t a defined term. Everything is natural for me.
-
Xantham should work here and it won’t be sticky it will be a bit slimy if that’s ok with you. Get a clear variety (it can be crystal clear).
-
Polyethylene waxes can have different melting points and different % would be needed to achieve the same viscosity. It also depends on desired viscosity of the product and what else do you have in the formula. You need to experiment with your wax to see what thickness it gives you at different levels. Try samples with 1, 3 and 5% and you will have an idea.

Since I lived in both the US and Europe I can confirm that 110 works perfectly in Europe. But 220 won’t work in the US in most cases.
-
In summary you need SCI, CAPB (around 20%) and I would adivice Olefin sulfonate as a second dry surfactant (you can also use SLSa it lathers better but less mild). You want your dry ingredients to be around 70%. This all is very roughly.
-
A product you are trying to make is called syndet bar. I noticed an interesting trend, there were 6 or 7 conversations about syndet bars on chemistcorner recently. My advice is to get swiftcraftymonkey’s ezine on shampoo bars. It is the best summary for such products. Don’t add cationic polymers and you will be able to use it on the face.

@cossci21, I haven’t formulated hair styling products yet, but I was doing research recently (I am thinking of formulating very strong hold clear hair gel). It looks like many of strong/ultimate hold products include VP/VA copolymer and PVP. I found the first one on makingcosmetics and they say it’s “Very effective film-forming agent and fixative for hair care products”. Maybe this is what you need for your formula?

Perry it’s very impressive! Great to know more about people on the forum.
@Belassi I found your books on Amazon:) -
You don’t get responds because of your attitude. Also if you don’t know who swiftcraftymonkey and call her self proclaimed you are clearly lacking knowledge about formulation world (which is quite small).
-
@S_AlAhdab, it is a very good question. I was wondering how low you can go until the soap becomes unstable.
@mikethair, would you mind commenting as a soap expert? Can the pH of the traditional soap be decreased?
-
@Perry thank you very much! Your podcast is the reason why I started formulating.
-
Agreed

I have been formulating with HLB in mind for the first year (after I just started). Then I was told by more experienced people who reviewed my formula that adding glyceryl oleate to bring HLB of the system (glyceryl stearate/PEG-100 stearate that has HLB of 11.5) down to 7-8 (which is HLB of most veg oils) is a bit overkill. But I still see advices of professionals on this forum to calculate HLB.

I personally don’t like glucosides. Especially for hair products (that is why my question was “why decyl glycoside”). The reason why I said it is considered to be mild is a result of zein test according to which it can be classified as mild comparing to other surfactants (such as SLS, SLES). The result of zein test isn’t 100% proof but it is a piece of scientific evidence. I didn’t mean that there are no people (and animals?) who are sensitive to it. I don’t have experience with animal products but my first guess would be CAPB, not decyl glucoside.
