Bentonite Sodium Stearoyl Lactylate ●
TL;DR. This ingredient is primarily a rheology modifier and emulsion stabilizer, helping thicken formulas, suspend particles, and improve texture. It is especially useful in creams, masks, cleansers, and mineral-heavy systems.
What does Bentonite Sodium Stearoyl Lactylate do in a cosmetic formula?
This ingredient is primarily a rheology modifier and emulsion stabilizer, helping thicken formulas, suspend particles, and improve texture. It is especially useful in creams, masks, cleansers, and mineral-heavy systems.
Is Bentonite Sodium Stearoyl Lactylate clean?
From a clean-beauty perspective, this ingredient is generally well accepted, with low sensitization concern and no major restricted-list friction. The main quality questions are purity, heavy-metal screening for the mineral fraction, and supplier documentation.
Is Bentonite Sodium Stearoyl Lactylate sustainable?
This material combines an inert mined mineral with a fatty-acid and lactic-acid derived surface treatment. The organic portion is expected to be biodegradable, while the mineral portion is not biodegradable but is generally environmentally inert.
Is Bentonite Sodium Stearoyl Lactylate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when the mineral source, processing aids, and fatty-acid feedstock meet standard documentation requirements. Its Green Chemistry profile is favorable because it can reduce the need for synthetic thickeners and uses a simple mineral backbone with biodegradable organic functionality.
How does Bentonite Sodium Stearoyl Lactylate work chemically?
Technically, this is a surface-modified layered silicate system, where platelet particles are treated with an anionic fatty-acid ester salt to improve wetting, dispersion, and emulsion stabilization. It is typically used at low single-digit levels, swells or disperses depending on water phase and shear, and performs best when fully hydrated before high oil or electrolyte loading.
