Calcium Sodium Borosilicate

Summary

Calcium Sodium Borosilicate is one of the effect materials that bends light into pearl and glow. It appears in 35 products in our range.

About

On an ingredient list it is written as Calcium Sodium Borosilicate, Calcium Aluminum Borosilicate. It is synthetic (borosilicate glass, ground to particle size for cosmetic use).

In the Formula

It is an effect material. It does not add pigment so much as bend light, which is what reads on skin as pearl, glow or a soft-focus sheen. Formally it is classed as bulking agent / effect pigment (borosilicate glass).

The Evidence

Its safety for cosmetic use has been assessed by the expert panel review Safety assessment of borosilicate glasses as used in cosmetics (Becker LC, 2013, Int J Toxicol, PMID 24174476). We cite what the ingredient is assessed for, not what a finished product was claimed to do.

Honest Limits

Calcium Sodium Borosilicate does its job inside the formula. It is not an active, and nothing on this page should be read as a treatment claim.
