Disturbing the team to consider again and have questions. 1. Propanediol use dissolve Salicylic Acid in this cream, right? See the instructions say 1,3- Propanediol can be used instead of Propylene Glycol , any type of Glycol and Glycerin to act as: Humectant / Skin-Feel, Solvent, Preservative Booster and how many % is good for that will melt Salicylic Acid 2. Butylene Glycol is a solvent. Salicylic Acid in this formula? Propanediol 3. If you want to use Encapsulated Salicylic Acid (Powder, Timed-Release) 4% (= Salicylic Acid 2%)In which step because he saw the instructions saying Encapsulated Salicylic Acid ( BHA ) powder when added to any formulation There is a chance that the formula will lose its viscosity. (liquid) 4. Personally, I have no experience in mixing. Dimethicone suggest these two % Dimethicone and Cyclopentasiloxane and% suitable for this type of skin as well 5. Dimethicone which one should I use? Thank you team

Hello

1. Propanediol use dissolve Salicylic Acid in this cream. right? See the instructions say 1,3- Propanediol can be used instead of Propylene Glycol , any type of Glycol and Glycerin to act as: Humectant / Skin-Feel, Solvent, Preservative Booster

1, 3- Propanediol soluble Salicylic Acid , but in this formula, the team thinks that The formula developer chooses to use it. Salicylic Acid water soluble type. The reason is because if using Salicylic Acid Normal type has a high chance of sludge formation when the formula is cooled.

3. If you want to use Encapsulated Salicylic Acid (Powder, Timed-Release) 4% (= Salicylic Acid 2%) put it into which step because you see instructions saying Encapsulated Salicylic Acid ( BHA ) powder when added to any formulation There is a chance that the formula will lose its viscosity. (liquify)

if the formula contains Xanthan Gum No problem

4. Personally, I have no experience with mixing. Dimethicone so please suggest these two % Dimethicone and Cyclopentasiloxane and% is suitable for this skin type as well

Dimethicone is non-volatile. therefore giving more weight on the skin But that doesn't mean gooey. sense of use Dimethicone is smooth on the skin. Cyclopentasiloxane can volatilize therefore lighter Dimethicone In case of dry skin, recommend Dimethicone because of its non-volatile nature Therefore, it is coated on the skin and prevents the loss of water of the skin. In case of choosing Dimethicone but scared Choose one that has a low thickness, such as Dimethicone (Very Light/5, Low-Odor)

Thank you team
