Why doesn't normal BHA dissolve?

Postby ssper1997 » Sat Nov 10, 2018 2:37 pm

Ingredients BHA 2% Isopentyldiol 7% water 91% when dissolved in Isopentyldiol The powder dissolves well, but when you add water it becomes a very cloudy seal. The separator is not dissolved. When I try to add Propylene Glyco 5% and continue spinning, it still doesn't dissolve completely. It's a cloudy color floating on top. Please give me a solution to complete the formula.

Hello, it's caused by a water-based formula. Solubility Salicylic Acid with Isopentyldiol must be dissolved without water. when the formula contains water precipitation of Salicylic Acid will happen. Water formula is recommended to use. Encapsulated Salicylic Acid (Powder, Timed-Release) to prevent this kind of problem.

If you can replace it with a new one, can you put it like this? Bottle contains 100 ml. Isopentyldiol 98% (98ml) BHA 2% (2g)

Ask for more information. Use Isopentyldiol 20%with BHA 2% after melting, can you use it? Or is there a recipe for how to do it? BHA simple

[quote="ssper1997"]Any questions please use Isopentyldiol 20% vs BHA 2% Once it's melted, can it be used right away? Or is there a recipe for how to do it? BHA Simple
Isopentyldiol 20% BHA 2% and the other 78% don't know what it is?

Hello, I can't do it. Learn to confirm according to the same advice that has been suggested previously. Must use Salicylic Acid soluble type or type Timed-Release dispersed in the formula.
