Polyvinylpyrrolidone (PVP) for Peel-Off Masks

For peel-off mask formulations, Polyvinylpyrrolidone K90 (PVP-K90) is generally the most suitable type. Its high molecular weight helps create a strong, cohesive film that is necessary for the mask to peel off effectively.

Other types of PVP, such as PVP-K15, PVP-K17, PVP-K30, and PVP-K60, have lower molecular weights and are typically used in liquid styling products. While they might be used in combination with PVP-K90 to fine-tune the film properties, PVP-K90 is the primary film-former for peel-off masks.

Usage Percentage:
The optimal percentage of PVP to use depends on the desired film strength and the specific formulation. The product descriptions do not provide a specific percentage range for peel-off masks. It is recommended to start with a percentage and adjust based on testing to achieve the desired peelable film consistency and strength.

Packaging:
Once the peel-off mask is finished, it should be stored in an airtight container, such as a tube or jar, to prevent the product from drying out. Ensure the packaging is clean and suitable for cosmetic products to maintain hygiene and product stability.
