I believe VLT is perfectly safe. It’s an excellent thickener with great sensorials and improves preservative efficacy.
-
Read the PDF book I posted about that.
-
Use 70/30 methyl/propyl. The propyl is harder to dissolve in my experience.
-
For creams, I generally am at 95%.

When you try dissolving crushed aspirin in anything, you are going to discover that it is very different.
-
You will need to use an oil soluble dye.
-
aspirin is not salicylic acid.
secondly, have you checked your ingredients for comedogenesis? -
I bought mine from an outlet in the USA that imports it from a co-op in Ghana. To purify it you have to melt it and filter it.
-
Serge, Bob’s comment is right on, you need to experiment.
If all you are doing is solubilising essential oils, then you don’t need to consider emulsion properties really, it is simply a solutions issue.Remember that though we call them “oils”, essential oils are a mixture of all sorts of types of chemicals, including esters, aldehydes, alcohols, terpenes, and so on. -
Another possibility is to replace the CAPB with Dehyton AB 30, a similar betaine that possesses an extra nitrogen ion giving a cationic effect.
-
Remove the cetyl alcohol.
-
I was playing around with one of our simpler products, a hand soap based on ammonium rather than sodium, and tried substituting Dehyton AB30 for the usual CAPB. The thickening is a lot more but on trying to add water I realised it was about to go into the hex phase and set solid. So if you want to try exploring that oddity, it appears AB30 is a good one to use.
-
5.5 is perfect. Adding 1 to 1.5% of Lamesoft PO-65 should help. Or a solubilised ester.
-
Not good to use tap water. Might be full of salts.
What is the pH? -
You’ll just have to try it and see!
-
It comes as thin as water.
-
Thanks for that. I checked out BASF’s sell sheet on ULProspector. I doubt that AO45 thickens (itself) with salt. It’s being promoted as an alternative to regular CAPB like their PK45 product, and regular CAPB doesn’t thicken if you add salt; rather, it can be used with anionics as part of a thickening system. I have another BASF betaine, AB30, and that doesn’t thicken with salt although it will thicken an anionic system.

The old scale-up problem.
-
Yes it might very well be sulfamic acid. It’s a sort of orange-pink colour, but possibly it’s been coloured, who can say. It disappears limescale like nothing I’ve seen before.
-
Phosphoric acid is not to be used in consumer products because it pollutes water supplies and causes algae blooms. Maybe that is why Cillit is no longer on the market.
-
Not very corrosive. It won’t attack metals, it leaves chrome fittings sparkling clean.
-
Update: This is quite foamy, a bit too much in fact. Reduce the SLS to say, 4% and add 6% water. Otherwise great!

The usual way for me is:
1. I might see some interesting substance in one of the trade publications, or I read a patent, or …2. I send off for a sample and in due course (usually) it arrives.3. I experiment with some sample formulations (usually the manufacturer’s ones so as to be predictable) and decide whether I want to formulate with this or not.4. If not I thank the manufacturer, if yes, I consult the catalogues of the two redistributors available to me, to see if they stock it. If they don’t, I get back to the original contact and ask for details of their representative in Mexico.5. I get in touch (or vice versa) with the in-country rep. Now comes the tricky part. Somehow I have to be able to buy in max. 25Kg packages since I just can’t physically deal with anything bigger. Whether this is possible or not, in my experience, depends on:“Am I the only prospective customer?”If the in-country distributor already has or can get other customers for the same product he may very well be amenable to splitting a drum.I apologise if the above seems a bit convoluted, it’s just my own experience of this business and it applies to Mexico specifically. -
There are many distributors. Probably what you need is a repackaging distributor: one that buys large quantities and repackages it so as to allow smaller purchases. For instance I can’t deal with a 55 gallon drum of surfactant but I can manage 25Kg containers.
