Troubleshooting Allantoin Solubility and Texture in Gel Cleanser & Toner
คำถาม
I am trying to create two formulations:
Toner for Clogged Pores
- Water: 94%
- Encapsulated Salicylic Acid: 5%
- Preservative: 1%
Gel Cleanser
- Water: 71.8%
- amino wash (Sodium Lauroyl Glutamate): 15%
- Allantoin: 0.2%
- Baby Foam (Sodium Cocoyl Isethionate): 10%
- pentylene glycol: 3%
- Preservative: 1%
When mixing the Gel Cleanser formula, I encountered two main problems:
Allantoindid not dissolve completely, even after extensive stirring. There was a sediment of undissolved powder at the bottom.- The mixture remained very liquid (like water), not forming a gel texture.
I tried adding a small amount of salt to thicken it, but it didn't help significantly.
How can I fix these issues?

Toner for Clogged Pores
- Water: 94%
- Encapsulated Salicylic Acid: 5%
- Preservative: 1%
This formula is suitable for a BHA toner focused on exfoliating and addressing clogged pores. As the staff mentioned, it's generally recommended to keep this type of toner simple and avoid adding ingredients like whitening agents, as the toner might need to be washed off depending on skin sensitivity, which would reduce the effectiveness of leave-on ingredients.
Oil Control Gel Cleanser
- Water: 71.8%
- amino wash (Sodium Lauroyl Glutamate): 15%
- Allantoin: 0.2%
- Baby Foam (Sodium Cocoyl Isethionate): 10%
- pentylene glycol: 3%
- Preservative: 1%
- SugarThick (PEG-120 Methyl Glucose Dioleate): 3% (Recommended for thickening)
The staff recommended adding SugarThick at 3% to achieve a gel texture and address the issue of the formula being too liquid. They also advised removing Pure MSM from this wash-off product.
Gel Cleanser Mixing Instructions
Here are the steps for mixing the gel cleanser, incorporating the solutions for the issues you encountered:
- Prepare the Water Phase: Measure out the Water (71.8%).
- Dissolve Allantoin: Add Allantoin (0.2%) to the water. Stir well to dissolve. Allantoin should dissolve at this concentration in water at room temperature. If you see undissolved powder remaining after thorough stirring, it indicates that too much Allantoin was added or it wasn't fully dispersed initially. You should filter out any undissolved solid particles using a coffee filter or fine mesh.
- Add Other Water-Soluble Ingredients: Add amino wash (15%), Baby Foam (10%), pentylene glycol (3%), and Preservative (1%) to the water mixture. Stir gently to combine the ingredients. Avoid vigorous stirring at this stage to minimize foam formation.
- Thicken with SugarThick:
- Gently heat the mixture to approximately 70°C.
- Add SugarThick (3%) to the heated mixture.
- Stir gently but continuously until the SugarThick is completely dissolved and the mixture starts to thicken into a gel consistency. Avoid creating excessive foam while stirring.
- Cool Down: Let the gel cool down to room temperature.
Regarding the appearance, the final gel should be a stable, consistent texture. The clarity or opacity will depend on the specific raw materials used, but it's likely to be clear or slightly hazy rather than cloudy white unless one of the ingredients inherently causes cloudiness. The separation you observed was likely due to the lack of a proper gelling agent, which adding SugarThick should fix.
The combination of amino wash and Baby Foam in this formula should provide a soft and sufficient lather, as confirmed by the staff. If you desire even more foam, you could consider slightly increasing the percentage of Baby Foam, keeping in mind the total percentage of ingredients should add up to 100%.
