Must update you on this one. After 2 weeks on stability testing all samples (room and elevated temperature) significantly lost original viscosity. Result was water-thin liquid. No good.

For a hair conditioner pure Behenyl Alcohol is too expensive. Best is a commercial blend of Cetearyl Alcohol (30% - Cetyl, 70% Stearyl). Behenyl quats eg. Incroquat Behenyl TMS from Croda give nice conditioning effect without build up.

You may need to include wax with higher melting point. May be Candelilla or Carnauba. Also inclusion of butters like Cocoa, Shea, Mango and the like may help with consistency. Good luck!

Reporting back on a trial with Konjac Root. I have used Glucomannan 95% purity powder. Happy with the result. At 0.5% I got clear flowable gel with 10% ascorbic acid. Will continue work with this formula. Thanks, Mark for a great suggestion.

You can try Incromectant LAMEA ( Acetamide MEA and Lactamide MEA blend). I think it is substantive to the skin and claimed to be superior humeactant comparing to Glycerin.

Don’t believe the label. I have seen many labels that made me smile

Crill 6 (Sorbitan Isostearate) and Cithrol GMO (Glyceryl Oleate ) from Croda may fit the bill in terms of solubility. It’s unlikely that this type of surfactants will foam IMHO.

Emu oil is not really an oil, but animal fat. Think of chicken broth and what is forming on the top of it. One of the best solubilisers I have tried is an ingredient called Solubilisant LRI (PPG-26 Buteth 26 and PEG-40 Hydrogenated Castor Oil) from Sensient.

I run small batches on Reverse Osmosis water. You can get various size units and holding tanks. Buying water for shampoos will be tedious to say the least.

Great. Sounds rather promising. On my way to hunt 95% powder. Thanks again.

I use Azulene in face cream. Very small amount just for a hint of colour. Wrinkle reducer? I doubt it very much, but it is good for sensitive skin. I have reasonably good colour stability, but I do not hold product in stock for a long time. Can vouch for about 12 months. Level depends on depth of colour required. I made up 1% dilution in solvent (Caprylic/Capric Triglyceride). Level of use about 0.05% to my memory.

Mark,
I had to Google Konjak Root. Haven’t heard of it before. Looks like it sold in Australia as weight-loss supplement.
Have you tried it in the formula and at what levels?
-
Thanks Ozgirl! The pH is likely to be around 3, not 4. I guess it is back to tried and proven Xanthan gum. It makes a sloppy liquid gel with 30% AHAs. I haven’t tried this formula with ascorbic acid but if I can’t find a better alternative, then I’m stuck with it.
-
Normally Carbopols are useless at low pH. There is Carbopol Aqua CC, but I haven’t tried it and not sure whether it is approved for use in Australia. Good thought though. Thanks, will check it out.

The odour of lanolin depend on the method of refining. Usually solvent processing leaves lanolin with more sweet odour. I suspect Chinese lanolin has been processed this way. Any true lanolin will have specific lanolin odour. There are many Lanolin derivatives that have no odour. For example, water-soluble PEG-75 Lanolin.
