Ultra-fine Silica

TL;DR. This ingredient is mainly used as an absorbent, anti-caking agent, texture modifier, and soft-focus mattifier. In powders, gels, and creams, it helps control oil, improve slip, and reduce clumping.

What does Ultra-fine Silica do in a cosmetic formula?

This ingredient is mainly used as an absorbent, anti-caking agent, texture modifier, and soft-focus mattifier. In powders, gels, and creams, it helps control oil, improve slip, and reduce clumping.

Is Ultra-fine Silica clean?

Clean-beauty standards generally accept this ingredient when it is non-nano and used in non-inhalable formats. The main caveat is particle size, since very fine airborne powders can be a respiratory concern during loose-powder use or manufacturing.

Is Ultra-fine Silica sustainable?

This material is mineral-derived or made from mineral feedstocks, and it is not biodegradable because it is inorganic. It is generally environmentally inert, but mining, refining, and energy use in processing are the main sustainability considerations.

Is Ultra-fine Silica COSMOS-approved?

It is generally permitted under COSMOS-natural and COSMOS-organic standards when it meets mineral, purity, and particle-size requirements. From a Green Chemistry lens, it scores well for stability and low reactivity, but less strongly on biodegradability and renewable sourcing.

How does Ultra-fine Silica work chemically?

This compound is an amorphous inorganic oxide with a high surface area, which explains its oil absorption, flow-control, and optical blurring behavior. Typical use varies widely by format, from low single-digit percentages for slip and anti-caking to higher levels in powders and mattifying products, and it is stable across normal cosmetic pH ranges.
