@Belassi, Awesome! Congratulations! Are you using a specific coffee extract?
-
I wouldn’t. I knew that there are lots of companies doing this, but I’m surprised that this thing is becoming so normal.
When I add an API (oils in this case) the quantity is justified on its pharmacological effect and it is based by pharmaceutical/medical scientific articles/books. -
Now it makes more sense
Thank you -
Is acid ascorbic stable in that formulation?
-
The urea must be in fine particles and I think Merck can provide it.
You can dissolve urea in a mixture of glycerol and alcohol which can be incorporated in the simple ointment base (10% lanolin, 90% petrolatum) -
Awesome info! It would be great to read an article regarding adding different oils in shampoo. Any information is much appreciated!
Thank you -
So they are used just to speculate? Or in other words, it is added in small quantities (0.1%) just for ad purpose?
-
I was thinking the same about panthenol (about 1%) and 0.5-1% argan oil. Both are expensive here.
-
What would be the % for pantenol and argan oil?
-
The guy have seen lots of youtube videos, must be serious!
-
Now that you have seen lots of youtube videos, you are ready to skip university or even better to teach there.
-
Yeah, but 5% of a blend with 10 ingredients means you can find only traces of those ingredients
I tend to believe, after a few months, urea will be transformed in NH3 and you will notice a slightly increase of pH.
Why not go for a much cheaper humectants? -
OMG, where are you from?
What about alibaba.com, they do ship worldwide. -
What is the purpose of Lactil in the formulation?

It usually irritates me when I get a request to formulate a product in a very short time. And I always say, if you want a formulation, made on paper without any testing than I can do it 5 minutes, but don’t come back to me and say it didn’t work, or it was unstable.
Two months for 6 formulations is very short time just for formulating, excluding stability tests.
I’d ask at last 6 months only for formulations…. -
Check for the same model on ebay. I’m sure you will find it.
-
Bill_Toge please provide a few article links about what you said because it is interesting
Thank you -
You can add some acid too.
-
“I need a hair manufacturer” lol

That would be enough, but you should check how much foam does the shampoo generate.
-
Unfortunately we do not work with tween 60 and span 60, but that indeed is a good idea.
-
A desperate way to sell your product. Very bad.
-
I have cetearyl alcohol 15%, petrolatum 10%, paraffin oil 4% and tween 80/span 80 4% for hlb around 12
In the oil phase I also add propylene glycol 5% which I’m thinking to remove it.
Water phase is only 40% water and 0.75% hec -
For a small ph increase you will need very little tea. But you can go for the sodium salts as well.
-
Tested and I can confirmed, menthol dissolves very easy in the oil phase especially in a higher temperature! Very nice!
Since we are in the topic, I have an other question.
When I add all these substances in the oil phase (especially methyl salicylate is around 15%) will increase the quantity of the oil phase and based on my tests, the final cream does not have a high viscosity (I had to add HEC to solve this issue) and I tend to believe the stability is not the best. Should I decrease the oil phase and add up more water (and hec) so the oil phase will be emulsified better? I’m going to test this tomorrow anyway. Thank you
