Calcium Sodium Borosilicate
Calcium sodium borosilicate and calcium aluminum borosilicate are shimmering powders composed of very tiny flakes of shiny glass-type compounds. Frequently used in makeup, they give the skin a gorgeous glow.
Calcium sodium borosilicate and calcium aluminum borosilicate are made in labs by fusing silica with several different oxide compounds, depending on the colour wanted.
In addition to their shimmering qualities, the two borosilicates are good bulking agents, helping to give products the desired consistency.
