Disteardimonium Hectorite

What is Disteardimonium Hectorite?

Disteardimonium hectorite is a synthetic, organo-modified smectite clay derived from natural hectorite through quaternization with distearyldimonium groups. This process makes it dispersible in oils and organic solvents, unlike natural clays. Commonly found in anhydrous products like foundations, mascaras, lipsticks, sunscreens, and deodorants, it functions by absorbing oils and swelling to create a three-dimensional gel network. This structure traps and suspends insoluble particles such as pigments, pearls, or actives, ensuring even distribution and preventing settling or clumping during storage or application. Its thixotropic properties allow the product to thin under shear for smooth spreading and thicken at rest for stability. Approved by regulatory bodies for cosmetic use, it enhances texture without adding water to formulas.
