Thickening a Liquid Sunscreen Formulation with Satin Cream Maker

Regarding the sunscreen formulation being too liquid based on your formula and process:

As the staff suggested, the best way to increase the thickness and viscosity of the cream is by adding more Satin Cream Maker (Product ID 247).

• Satin Cream Maker acts as both an emulsifier and a thickener, helping to build the cream structure and increase viscosity.
• Adding an additional 1.5% of Satin Cream Maker (Product ID 247) as recommended by the staff should help achieve a thicker consistency.

Additional advice for the mixing process to increase thickness:

1. Follow your original mixing steps until you obtain the cream texture from combining the water and oil phases.
2. Allow the cream to cool down.
3. When the temperature of the cream is around 50-70°C (or slightly above 50°C), add the additional 1.5% Satin Cream Maker.
4. Mix thoroughly until you are sure that the Satin Cream Maker is completely dissolved into the cream. Complete dissolution is essential to achieve the desired thickness. The cream will gradually thicken as it cools down.
5. Once the cream temperature is below 50°C, then add the heat-sensitive ingredients (Alpha Arbutin and Mild Preserved Eco) and mix until uniform as before.

Furthermore, as the staff inquired, please ensure that the equipment used for mixing is appropriate and can effectively help the ingredients dissolve and combine well.
