Subject: Sodium alginate for mask
Regarding your questions about using Sodium Alginate in a mask formulation:
- Peel-off mask: Sodium Alginate acts as a film former on the skin and is suitable for mask formulations, but it does not create a peel-off mask.
- Usage percentage: For typical cream/mask formulas, a low concentration is recommended. You can start by testing at 0.5%. If the film effect is not sufficient, you can increase it up to a maximum of 1.0%. Using more than 1.0% may cause pilling.
- Hardening: Sodium Alginate will not harden over time if stored properly to prevent moisture loss. This can be achieved by using suitable packaging or keeping it submerged in liquid. The hardening observed in the spherification video is likely due to drying out.
- Addition step: Sodium Alginate functions as a thickener and film former. It is typically incorporated into the formulation process, but the specific step can depend on the overall formula design.
- Wash-off or Leave-on: Due to its film-forming nature, Sodium Alginate is commonly used in wash-off masks.
