Calcium Sodium Borosilicate is a type of glass that is highly resistant to temperature changes, chemical influences and has very good optical properties. Its main component is boron oxide, together with sodium and calcium oxides. This material is known for its high refractive indices, which makes it an ideal choice for creating pearlescent pigments with high gloss.

Calcium Sodium Borosilicate is mainly used in the cosmetics industry, especially in the production of eye shadows and various types of nail polish. Due to its special properties, it is often used to create glossy and shimmering effects. In addition, it is also a component of some lip products such as lip glosses or lipsticks. Outside the cosmetics industry, it is also used as a component of heat-resistant glasses and building materials. The safety of Calcium Sodium Borosilicate has also been thoroughly investigated and is considered safe for use in cosmetics.
