Hermano supplies premium white bentonite selected from our own controlled mineral resource in China.
The material is available in natural and sodium-activated grades, with different particle-size, moisture, swelling, viscosity, binding and colour requirements discussed according to the application.
White appearance alone does not determine suitability. The recommended grade should be based on the end use, required specification and evaluation in the customer’s process.
Product Overview
Premium White Bentonite is supplied from our own controlled mineral resource in China and selected for its naturally light colour, mineral quality and stable processing potential.
The product can be supplied in natural form or as sodium-activated grades. The suitable route depends on the application, required swelling behaviour, viscosity, binding performance, particle size, moisture and colour requirements.
Rather than treating white bentonite as one standard product, Hermano works with customers to select the material and processing route before production. This helps balance technical performance and cost for the intended end use.
Natural and Sodium-Activated Grades
| Grade direction |
General description |
| Natural white bentonite |
Supplied in its natural form and selected for naturally light colour, mineral quality and processing potential. Performance depends on the mineral composition of the selected grade. |
| Sodium-activated white bentonite |
Prepared through a sodium treatment route intended to adjust the sodium character and performance potential of the material. The actual response should be confirmed in the intended application. |
Both routes can be discussed with different particle-size, moisture and performance targets. The final selection should be based on the complete formulation or production process, not on colour alone.
Available Forms
- Natural white bentonite.
- Sodium-activated white bentonite.
- Crushed and dried white bentonite lumps.
- Fine white bentonite powder.
- Customized particle-size and moisture control.
- Bulk container supply or 25 kg bag packing.
Potential Applications
White bentonite can be evaluated for a range of industrial applications, including:
- Ceramic bodies, ceramic slips and refractory materials.
- Paper, coating and filler applications.
- Paints, coatings and construction materials.
- Rubber, plastics and other compounding systems.
- Absorbent and granulated mineral products.
- Drilling, HDD and geotechnical applications.
- Pet-care and clumping mineral applications.
- Cosmetic, personal-care and other high-whiteness formulations, subject to customer qualification and applicable regulatory requirements.
Application note: these are potential evaluation areas, not a claim that one grade is suitable for every application. Final selection should follow the agreed specification and application-specific testing.

Technical Selection
White appearance alone does not determine suitability for every application. The appropriate grade should be selected based on mineral composition, montmorillonite content, whiteness, particle size, moisture, swelling behaviour, viscosity, impurity control and the customer’s production process.
The table below shows the main information that can be reviewed when selecting a natural or sodium-activated white bentonite grade.
| Information to review |
Why it matters |
| End application |
Clarifies the required function, processing route and performance target. |
| Mineral composition |
Supports review of compatibility and functional potential in the intended system. |
| Montmorillonite content |
Helps assess the bentonite-related performance potential of the selected material. |
| Whiteness |
Supports visual and colour requirements where the final product needs a light appearance. |
| Particle size |
Affects dispersion, mixing, suspension and processing behaviour. |
| Moisture |
Can influence handling, packaging, processing and final formulation consistency. |
| Swelling behaviour |
Helps match the grade to sealing, suspension, binding or absorption requirements. |
| Viscosity |
Supports selection where rheology, suspension or flow control is important. |
| Impurity control |
Application-specific review helps identify requirements for colour, processing and regulatory compliance. |
| Natural or sodium-activated route |
Helps balance performance potential, processing requirements and cost. |
Information Needed for Grade Selection
To recommend a suitable grade and arrange an evaluation sample, please share the following information:
- Intended application and final product type.
- Required whiteness or colour target.
- Preferred natural or sodium-activated route.
- Required particle size, lump size or powder specification.
- Moisture requirement and handling conditions.
- Required swelling, viscosity, binding or absorption behaviour.
- Current material specification or a reference sample, if available.
- Packing, transport and order quantity requirements.
Quality and Application Evaluation
Samples should be evaluated in the intended formulation or production process. Relevant tests may include colour and appearance, particle-size distribution, moisture, dispersion, hydration, viscosity, swelling, suspension, binding performance and compatibility with other raw materials.
For cosmetic, personal-care and other high-whiteness applications, suitability should be reviewed against the customer’s specification and applicable regulatory requirements. White appearance alone is not confirmation of cosmetic-grade suitability.

Packaging and Supply
White bentonite can be supplied in bulk containers or 25 kg bags. Crushed and dried lumps, fine powder and customized particle-size or moisture options can be discussed according to the application.
Samples, TDS, COA and technical discussion are available upon request. Please provide the intended application and required specification so that the relevant grade options can be reviewed.
Frequently Asked Questions
What is premium white bentonite?
Premium white bentonite is a commercial description for selected white bentonite with a naturally light colour. It can be supplied in natural or sodium-activated grades, and suitability depends on the application and agreed specification.
What is the difference between natural and sodium-activated white bentonite?
Natural white bentonite is supplied in its natural form. Sodium-activated white bentonite is prepared through a sodium treatment route intended to adjust its sodium character and performance potential. Both should be evaluated in the intended application.
Does white colour determine suitability?
No. White appearance is only one selection factor. Mineral composition, montmorillonite content, particle size, moisture, swelling behaviour, viscosity, impurity control and the customer’s process also matter.
What forms are available?
Natural white bentonite, sodium-activated white bentonite, crushed and dried lumps, fine powder and customized particle-size or moisture options can be discussed.
Can particle size and moisture be customized?
Customized particle-size and moisture control can be discussed before production. The suitable target depends on the application, processing method, handling conditions and packing requirements.
What applications can white bentonite be evaluated for?
Potential evaluation areas include ceramic bodies, slips and refractories, paper, coatings and fillers, paints and construction materials, rubber and plastics, absorbent products, drilling and geotechnical uses, pet care and selected high-whiteness formulations.
Can it be used in cosmetic or personal-care products?
It can be evaluated for high-whiteness formulations subject to customer qualification and applicable regulatory requirements. White appearance alone is not confirmation of cosmetic-grade suitability.
What documents and samples are available?
Samples, TDS, COA and technical discussion are available upon request. The relevant documents should be confirmed for the selected grade and intended application.
