As a layered silicate material, bentonite is widely used in cosmetics for thickening, improving sensory texture, suspending powders, stabilizing rheology, and forming oleogels. Depending on its structure, origin, and modification method, cosmetic-grade bentonite can be categorized into several types, including natural sodium/calcium bentonite, purified montmorillonite, and organo-modified bentonite intercalated with quaternary ammonium salts (e.g., distearyldimonium hectorite).
In color cosmetics, the most commonly used type is organo-modified bentonite, which is compatible with oil phases, silicone oils, and certain esters, and provides pronounced thixotropy and thickening performance.
Core Advantages of UNI-POWDER Bentonite Powder
1. Enhances Pigment Suspension and Uniformity
Optimized particle size distribution and uniform layer surface charge enable the powder to more easily unfold its lamellar structure in oil or silicone oil phases, forming a stable three-dimensional network. Viscosity builds up quickly, shear thinning is pronounced, and spreadability is improved, resulting in a more stable system.
2. Strong Oil-Phase Compatibility and High Formulation Flexibility
Suitable for various volatile silicone oil systems and complex multiphase formulations, reducing risks of slow gelation or incomplete dispersion caused by differences in oil phases.
3. Low Impurity Content and Clean Color
Meets color cosmetics requirements for appearance, stability, and color purity, providing higher safety and superior skin feel.
Pre-Activated Gel: Superior Performance in Formulations
A pre-activated gel is based on powdered bentonite, and through pre-shearing, controlled polarity adjustment, and an internal activation system, it can form a gel directly during use without requiring high-intensity dispersion.
1. Easier to Use and Higher Production Efficiency
Ready-to-use gel requires no high-shear equipment, ensures better batch consistency, and reduces production time and cost.
2. More Precise Rheological Control
Exhibits stable and controllable performance in emulsions, creams, foundations, concealers, and solid sticks.
Pre-Activated Gel: Superior Performance in Formulations
▶ Skincare
Bentonite is widely used in skincare products such as emulsions and creams as a thickening and stabilizing agent. It effectively increases viscosity, maintains product stability, and prevents separation, sedimentation, or oil-water stratification, ensuring long-term product performance.
▶ Sunscreen
Bentonite enhances the dispersion and stability of UV filters in sunscreen formulations, improving their overall efficacy. Its stable properties prevent sedimentation and oil-water separation, ensuring even application and long-lasting protection.
▶ Color Cosmetics
Bentonite is also valuable in makeup formulations such as foundations and concealers. It helps regulate oil content, enhances product spreadability, and improves longevity for a fresher appearance throughout the day. In lip lacquers, it contributes to the development of transfer-resistant formulations and boosts pigment stability.
With its versatility and unique properties, Bentonite and Bentonite Gel offer significant potential for cosmetics applications, enhancing texture, thickening performance, and suspension capability. To learn more about Bentonite and how to use it effectively, contact us!
