Hectorite Clay ●
TL;DR. This ingredient is used mainly as a rheology modifier, suspending agent, and absorbent, helping formulas feel more stable and less runny. It can also add slip and a soft-focus finish in masks, creams, and color cosmetics.
What does Hectorite Clay do in a cosmetic formula?
This ingredient is used mainly as a rheology modifier, suspending agent, and absorbent, helping formulas feel more stable and less runny. It can also add slip and a soft-focus finish in masks, creams, and color cosmetics.
Is Hectorite Clay clean?
It is generally well tolerated on skin, with low sensitization concern because the particles are insoluble and largely inert. Clean frameworks usually treat it as an acceptable mineral ingredient, with attention mainly to respirable dust control during manufacturing and impurity testing for heavy metals.
Is Hectorite Clay sustainable?
It is sourced by mining, so it is nonrenewable and tied to land-use and extraction controls rather than agriculture. It is inorganic and does not biodegrade, but it is not expected to bioaccumulate and is typically environmentally inert.
Is Hectorite Clay COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic products when naturally derived and processed by allowed physical methods. Its Green Chemistry fit is strongest on low reactivity and minimal solvent use, with the main limitation being nonrenewable mineral sourcing.
How does Hectorite Clay work chemically?
This material is a layered hydrated silicate mineral with a high surface area and charge-bearing platelets that swell or disperse to build viscosity and suspend pigments or powders. It is stable across typical cosmetic pH ranges and is commonly used at low single-digit percentages, with higher levels in rinse-off masks or anhydrous systems where stronger structure is needed.
