Colonial CNDF is also known as Meroxapol 311 and is, technically an ethylene oxide/propylene oxide block polymer termed peg/ppg-21/7 copolymer.
Surfadone LP-100 is N-Octyl-2-Pyrrolidone. I doubt there is an altenative

You do not define the grade of ColaQuat that you are using.
However, from what I gather both the PDQ and the SME grades comprise aqueous solutions. I suspect other types are similar. This being so, that is the reason the products fail to mix with an oil base.
What is the intended end use of this product? As Bob says, that level of limonene is really bad for the skin - and would not be permitted in a cosmetic product in Europe, at least.

Despite what you might think, I was trying to help you in sourcing the product that you are having problems with importing. The products I found via Google are described as being O’Douds - which is the name you gave in your original post. There are several variants for sale and I expected there to be something there that matched your requirements.
I don’t think I can help you any further.
-
Remember that Google is your friend.
I looked up the product and found that there are a number of UK suppliers of this - including Amazon and eBay. I don’t think the import duty from UK into ROI would be excessive, would it?

Glycolic acid would not be my ingredient of choice in a moisturising lotion. Is it meant to be a moisturiser or an AHA (exfoliating) product? I am somewhat confused.
-
I will refrain from commenting on the formula as a whole but, if you find potaasium sorbate is causing problems why not just replace it with another preservative? By doing this you will save a lot of wholly pointless investigation work.
-
organic and no contains no chemicals.
Dead before it starts.
All materials are composed of “chemicals”. I’m afraid with a philosophy like that you will get absolutely nowhere. Even water is a chemical. Look at this http://www.dhmo.org/facts.html

Please be aware that Veegum is for aqueous systems.
Check that the Aerosil grade is suitable for your oil mix.

The Silnos is not acting as a suspending agent so, yes, it does need replacing. Other suspending agents useful for this type of product are Bentone Gels http://elementis-specialties.com/esweb/esweb.nsf/pages/cosmetics
Another point that should be made is the technique used for pouring the mixture into the stick mould or container. The temperature must be carefully controlled at just above the melting point of the mixture so that it sets very quickly after pouring but remain in a liquid state for sufficient time to pour and set evenly.
-
Silnos silicas are in the form of micro-sized spheres - a completely different physical form to that of the fumed silica that I mentioned above. I doubt it would have any real effect as a suspending agent.
A binder is to improve the compatibility and ease the mixing of the powder and oil components. Binders do not necessarily assist in suspending power

A picky point perhaps but I feel obliged to give a correct explanation of Tyndallisation (referred above). It is not the heating to 121 °C for 15 minutes (that is the normal autoclaving procedure for aqueous products - which is very reliable. Dry products (instruments and suchlike) are sterilised at 150 °C for one hour dry heat.
Reading further into the Wiki entry you will find the correct procedure for Tyndallisation:
Tyndallization essentially consists of heating the substance to boiling
point (or just a little below boiling point) and holding it there for 15
minutes, three days in succession. After each heating, the resting
period will allow spores that have survived to germinate into bacterial
cells; these cells will be killed by the next day’s heating. During the
resting periods the substance being sterilized is kept in a moist
environment at a warm room temperature, conducive to germination of the
spores. When the environment is favourable for bacteria, it is conducive
to the germination of cells from spores, and spores do not form from
cells in this environment -
Have you checked Abe Books for your early edition of the book?
They have a number of copies (92) for sale, some of 2001 publication.Worth a look https://www.abebooks.co.uk/servlet/SearchResults?sts=t&an=&tn=Handbook+of+Cosmetic+Science+and+Technology&kn=&isbn=
That links to the UK site but they are worldwide.

That list is NOT an INCI list.
Venetian theriak is a very old term from traditional herbal practice and is ill defined as to what it actually is. “Theriak” is an ancient term for treacle.
The list you offered looks more like a part recipe for an 18th century formulation of some kind of elixir. Similar recipe products are still sold in continental Europe as “digestifs”.Your list (with the addition of liquorice) reminds me of Fernet-Branca (a very much acquired taste but I enjoyed it immensely after meals when I worked in the South of France -although it is an Italian product).
Are you certain your product is alcohol free?
-
The list you gave is a crude INCI LOI which is intended for consumer
information to enable them to avoid components that they may object to
(for a number reasons). These lists do help others in determining the
gross ingredient content but are quite useless in revealing detail -
this is where experience counts and very often a chemistry background
may be of little use.We are trying to help but we can do little
unless you are more open about the details. Nobody is trying to steal
any trade secrets from you as these days, trade secrets hardly exist and
if they do, they don’t remain secrets for very long.From the little you have revealed, what type of silica are you using?
Silica as used in cosmetics can vary from 1mm+ particles to “fumed silica” (Aerosil/Cabosil) where the particle size is extremely small and it can act as a suspending agent for pigments. Your revealed ingredient list lacks any other obvious suspending/stabilising agent and this may well account for the problems you are experiencing.
-
I have looked at these products. I had to go the South African site to obtain any ingredient information. Here, most offer a LOI and of those declared, all contain at least one conventional preservative - possibly not a commonly used one but a preservative nonetheless. There are one or two products which give no formula details on the website.
This company has an excellent marketing division turning something quite ordinary into something quite magical.

Whilst I was searching for new sources I found two alternative aucops. wordpress links which seemingly were both taken down during my search.
You may be lucky by googling the book title: Handbook of Cosmetic Science and Technology and hoping it is still available. It costs around $200 to buy.
-
Very, very dangerous!
Extreme risk of something horrible (and costly in legal fees) resulting from this exercise.
I strongly suggest that you give up with this and work on something more conventional and safer.
-
That is a great pity. I will look if I can find it elsewhere.
-
Sorry, but we can’t help you without more information regarding the formula/components of the product and details of the changes you have made.
-
Is this formula your own creation or is it something published?
Either way, please let us know what it is.
-
A very dangerous path you are going along.
If a cosmetic product has the ability to maintain the life of its intentionally included micro-organisms it will also have the ability to similarly maintain the lives of any contaminant organisms. The consequences of that could be catastrophic. Even if your packaged product complies with your requirements of a mono-culture, as soon as it is opened there is a distinct danger, almost a certaintly, of contamination.

Remember you can make your own sodium benzoate/gluconolactone mix.
-
As you seem to be able to obtain BASF materials (Texapon & Euperlan), have you enquired of the supplier of those if they also supply BASF preservatives (Bronidox is phenoxyethanol) or any others. Sodium benzoate and gluconodeltalactone is being pushed at the moment as a good preservative. I have not used it but it may be worth investigating. Sold as Geogard Ultra but you could add it as separate ingredients. There is a similar mix which additionally contains calcium gluconate.
Please don’t be too quick to dismiss sulfate based detergents. Most, if not all, of the bad press about these has be created by scaremongering Internet busybodies who have no real knowledge of anything except how to generate disquiet. I could make similar commetns about parabens where all the panic generated about these is based on some deeply flawed research carried out in the UK and, typical of these things, all further research pointing out these flaws has been dismissed as incorrect.

What is the problem with using alcohol as a fragrance solvent? Even strict muslim countries, where alcohol is normally forbidden, usually provide an exception for perfumes and products in which there is no easy access to the liquid contents e.g aerosols and crimp top sprays.
There are good reasons for alcohol being the solvent of choice for fragrances but I am unable to think of a reason where another solvent would be better.
-
I think you will need to do more than let the beer stand and go flat - a lot of CO2 can (and will) remain dissolved without extra encouragement to dissipate e.g vigorous stirring and/or heat.
Regarding fragrance, what market are you aiming for? I think that a predominately “hop” odour will be too restricting and only appeal to a beer connoisseur.
