Benonite Clay ●
TL;DR. This ingredient is primarily used as an absorbent, texture builder, and viscosity modifier in masks, cleansers, powders, and some emulsions. It helps bind oil and water into a thicker, more spreadable paste or gel-like structure.
What does Benonite Clay do in a cosmetic formula?
This ingredient is primarily used as an absorbent, texture builder, and viscosity modifier in masks, cleansers, powders, and some emulsions. It helps bind oil and water into a thicker, more spreadable paste or gel-like structure.
Is Benonite Clay clean?
From a clean-beauty perspective, this material is generally well accepted and has low irritation potential when used on intact skin. The main quality concerns are fine-powder inhalation during manufacturing or loose-powder use, plus routine screening for trace mineral impurities.
Is Benonite Clay sustainable?
This ingredient is mineral-derived, so it is not renewable in the plant-based sense, but it is abundant and typically processed with relatively simple physical methods. It is inorganic and does not biodegrade, but it is environmentally inert when responsibly sourced and purified.
Is Benonite Clay COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourced as an allowed natural mineral and processed without disallowed chemical modification. Its Green Chemistry fit is strongest on simple processing and low reactivity, with weaker alignment on renewability because it comes from mined deposits.
How does Benonite Clay work chemically?
This material is a hydrated layered aluminosilicate with exchangeable sodium or calcium ions, giving it high surface area, oil-binding capacity, and swelling or thixotropic gel behavior in water. It is often used around 1 to 25% depending on format, hydrates best with good dispersion and mixing time, and can lose structure in high-electrolyte or very low-pH systems.
