TIN

Safety grade: A**

Tin is a metallic element that is sometimes used in cosmetic formulations. It is a silvery-white metal that can be processed into very fine particles for use in beauty products.

As a surfactant in cosmetics, tin helps to reduce surface tension and allows different ingredients to mix together smoothly while also helping to cleanse and create a pleasant texture in the product.
