but the oil has to be free of phenols
WHY? -
You’ve got completely the wrong idea, I think. Surfactants are not fatty acids. Oils are fatty acids.
-
Licorice extract 5% - that is a huge amount. What kind of extract is that?
-
Alternative Alternative plan (Mine):
Create loads and loads of products and market them. Most will fail for one reason or another. Stop creating that type and try something different. Repeat as necessary. -
no

Here take a look and see what you think?
- Immediately I see olive oil I think, “People who do not know what they are doing.” -
I suspect the only real choices for buying it will be the original manufacturer or a China source. Not to mention that it is a drug not a cosmetic, surely?
-
No idea, sorry. I use the ammonium based surfactants.
-
Who knows, but it’s advisable to avoid high shear mixing with any thickener system.
-
I just looked up my formula for you. cyclopentasiloxane, 0.25% and dimethicone petrolatum, 0.25%. The d.p. is a Polytrap powder, one of my favourite ingredients. The D5 acts as a solvent for the Polytrap and later evaporates leaving the petrolatum/dimethicone film on the skin, it’s unbeatable for TEWL and gives great sensorials. But for a repellent, I’d leave out the d.p. and maybe use 0.3 - 1% of D5, you will have to experiment to find the optimum.
-
I forgot to mention: I use D5 in a skin cream. I reverse engineered an Ev&Crab product.
-
You mean D5? It depends where you are located. Its use is restricted in many countries. My thoughts are, that D5 would slowly evaporate from a leave-on due to body temp so, in a repellent, I doubt that you want the repellent partially evaporating. Or who knows, maybe D5 vapour is a mosquito repellent? You might become bigger than OFF, one day, I will be sitting in my Old People’s Making a coffee in a 500mL Pyrex beaker, and I’ll see you in the news, the man who made OFF obsolete.

And you will need to define exactly what you mean by “coconut milk”.
-
Is that increase in viscosity because of that surfactant or because of the salt in it? - Because of the salt. It has a LOT of salt in it. Might be a byproduct of the manufacture. You cannot thicken CAPB or Lauryl Glucoside with DEA. The problem with non-anionic surfactants is that you have to add thickeners, all of which impact your bottom line or/and customer appeal. Cheap = no customer appeal. Expensive = great sensorials.
-
You could always use it for cooking? Very healthy! I never use it in anything, because there are so many better ingredients for cosmetics.
-
Use a different preservative. No point in banging your head against a wall.
-
Not to mention the olive oil, herb infused or otherwise, will be loved to death by the Malessezzia and give you a dandruff problem.
-
This is to be expected. Green tea acts as an indicator.
-
I’m sure you will find a lot of useful information here.
-
Import them, then.
-
940 will not give the grade of gel you want. And TEA won’t work much above 63% anyway. This sanitiser thing is really annoying because of the supply shortages it has created.
-
Generally if I am developing something I can’t afford to have failures hanging around cluttering the place up. The good news is that you (should) get better at it. I suggest beginning by copying well known products that don’t have terribly complicated ingredient lists. My own first attempt at imitating something was primitive, but it worked, and encouraged me to keep going. I liked Evelyn & Crabtree’s shea hand cream so much, that I bought some organic shea on EBay, then I melted it, and mixed it with hair styling gel (carbomer!) to make a carbomer cream. Hair products are much more difficult than skin products, I think.

Unfortunately, waste is the name of the game. I shudder to think of the amount of raw materials I have discarded. Reading and researching can only take you so far. Ultimately you have to make formulae, try them, improve them, accept or discard them.
-
anything with salt in it.

First, please use centigrade, it’s the standard here.
And grams.
So, 150F is 150-32=118*5=590/9=65 degrees approx.
Marginal. Very marginal.
2 oz = 60grams. This is a very small amount, so will lose heat quickly.
If you intend to continue working with such small sample sizes, I recommend using a water bath and an induction cooker to be able to maintain an even temperature. Also, it’s really difficult to use high shear with such quantities. I normally experiment with a minimum of 250g, more often 500g. One of the problems of developing using very small sample sizes, is that errors, and there are always errors, multiply enormously when it comes time to make even a 5Kg batch.
