Calcium Sodium Borosilicate ●
TL;DR. This ingredient is primarily an effect pigment substrate, used to create sparkle, shimmer, and multidimensional light reflection in makeup, nail products, and some body-care formulas.
What does Calcium Sodium Borosilicate do in a cosmetic formula?
This ingredient is primarily an effect pigment substrate, used to create sparkle, shimmer, and multidimensional light reflection in makeup, nail products, and some body-care formulas.
Is Calcium Sodium Borosilicate clean?
From a clean-beauty lens, this ingredient is generally low-reactivity and low-sensitization because it is an insoluble inorganic particle. The main scrutiny is physical, including particle size for powders and eye-area use, plus trace-metal specifications from pigment coatings.
Is Calcium Sodium Borosilicate sustainable?
It is made from non-renewable mineral feedstocks in high-temperature furnaces, so its footprint is more about energy use than agricultural sourcing. It is inorganic and does not biodegrade, but it is not a plastic polymer and is expected to remain largely inert in the environment.
Is Calcium Sodium Borosilicate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic only when supplied as an approved mineral-derived color or effect material and when coatings and impurities meet the standard’s criteria. Its Green Chemistry profile is mixed, with mineral feedstocks and high heat limiting renewability, while inertness and low reactivity are favorable traits.
How does Calcium Sodium Borosilicate work chemically?
This material is an amorphous inorganic glass network containing alkaline-earth and alkali ions plus boron and silicon oxides, often engineered as thin reflective platelets with oxide coatings for interference effects. It is insoluble and stable across normal cosmetic pH, with typical use around 0.1 to 10% depending on the desired shine, and sometimes higher in color cosmetics.
