Borosilicate ●
TL;DR. This material is mainly used as an optical-effect particle, filler, and texture modifier. It can add shimmer, brightness, slip, or soft-focus effects, especially when paired with mineral color coatings.
What does Borosilicate do in a cosmetic formula?
This material is mainly used as an optical-effect particle, filler, and texture modifier. It can add shimmer, brightness, slip, or soft-focus effects, especially when paired with mineral color coatings.
Is Borosilicate clean?
From a clean-beauty perspective, it is generally considered inert, low-irritation, and not a common allergen. The main quality questions are particle size control, respirable dust management in powders, and trace metal purity.
Is Borosilicate sustainable?
This material is mineral-derived and not biodegradable in the way plant-based organics are, but it is generally inert and not a microplastic. Its footprint is tied mostly to mineral extraction and high-temperature processing rather than aquatic bioaccumulation.
Is Borosilicate COSMOS-approved?
It can fit COSMOS-natural when it meets mineral-origin and purity requirements, but it is not a meaningful fit for COSMOS-organic content calculations. Its Green Chemistry profile is strongest on stability and low reactivity, and weaker on renewable sourcing and energy-intensive manufacture.
How does Borosilicate work chemically?
The molecule is an amorphous inorganic network built from silicon, oxygen, and boron units, often supplied as fine reflective platelets or particles. It is insoluble, broadly pH-stable in normal cosmetic ranges, and usually used at low visual-effect levels in makeup, body shimmer, and radiance products.
