Product Overview

Pure-Flo® B80 by Oil-Dri is a naturally active bleaching and clarification adsorbent produced from an intergrowth of hormite- and smectite-type clay minerals. It is used in edible-oil refining and compatible liquid-purification processes where color reduction, residual-soap removal, phosphorus-related impurity reduction, trace-metal adsorption and filtration performance are important.

Unlike acid-activated bleaching earths, B80 relies on the inherent activity of its mineral structure rather than mineral-acid activation. This gives B80 a distinct position within the bleaching-earth family and makes it useful to evaluate where treatment performance, filtration behavior, product retention and process economics must be considered together.

For broader grade-selection guidance, see our Bleaching Clay & Purification Adsorbents collection and Oil Purification & Refining guide.

Product: Pure-Flo® B80

Manufacturer: Oil-Dri Corporation of America

Material type: Naturally active bleaching earth / bentonite-based purification clay

Primary applications: Edible-oil refining, color reduction, residual-soap and phosphorus-related impurity reduction, trace-metal adsorption and clarification

Activation: Naturally active; no mineral-acid activation

Commercial format: 908 kg vendor supersack minimum

Where Pure-Flo® B80 Fits

Edible-oil refining: Bleaching and purification of compatible vegetable oils, animal fats and related refinery streams.
Color reduction: Adsorption of compatible pigments and color bodies where the naturally active clay chemistry fits the feedstock.
Residual-soap reduction: Treatment of remaining soaps following upstream refining steps.
Phosphorus-related impurity reduction: Adsorption of residual phospholipid-related contaminants in compatible oil systems.
Trace-metal reduction: Treatment of selected metals that may affect downstream stability, oxidation or processing.
Clarification & filtration: Fine mineral adsorbent used with downstream filtration to remove the spent clay and associated contaminants.

B80 belongs in the broad bleaching-earth branch - not the selective-adsorbent branch.

B80 is most naturally evaluated where the objective is broad oil purification, color reduction and removal of compatible residual impurities. For more targeted pretreatment of soaps, trace metals and phosphorus-related contaminants, compare Pure-Flo® Select 350 and Pure-Flo® Select 450.

Why Choose Pure-Flo® B80?

Naturally active mineral structure: Provides bleaching and purification activity without mineral-acid activation.
Oil-refining application fit: Designed around purification of edible oils and compatible refining streams.
Broad treatment role: Can support reduction of pigments, residual soaps, phosphorus-related impurities and selected trace metals.
Filtration considerations: Particle-size distribution and clay structure influence filter-cake behavior, filtration rate and retained product.
Moderate surface chemistry: Naturally active grades may be useful where a less aggressively activated clay provides the preferred balance of purification and process economics.
Established Oil-Dri product: Manufactured by Oil-Dri Corporation of America within the Pure-Flo® purification-media family.

Final performance depends on feedstock, contaminant profile, dosage, temperature, contact conditions, filtration system and required finished-product quality.

What Can B80 Help Reduce?

Treatment Objective	General Role	Important Considerations
Color bodies & pigments	Core bleaching application	Performance depends on pigment chemistry, feedstock condition, dosage and contact conditions.
Residual soaps	Common refining objective	Incoming soap concentration and upstream refining efficiency affect required adsorbent dosage.
Phospholipid-related impurities	Compatible purification target	Residual phosphorus levels and feedstock condition should be measured when this is a critical downstream specification.
Trace metals	Selected metals may be reduced	Actual performance is element, feedstock and process dependent.
Oxidation products	May support reduction of compatible degradation compounds	Adsorption varies with compound chemistry and oil condition.
Suspended / entrained material	Removed with the spent clay during filtration	Clarification performance also depends on the filter system and cake formation.

Important: B80 should not be assumed to remove every contaminant equally. Representative bench or production testing is recommended when changing feeds, grades or treatment conditions.

Naturally Active vs. Activated Bleaching Earth

Selection Factor	Pure-Flo® B80	Activated / Specialty Bleaching Earth
General treatment approach	Naturally active mineral surface	Surface properties modified through additional processing
Acid activation	No mineral-acid activation	May include acid activation depending on product
Typical selection emphasis	Balance of purification, filtration behavior, product retention and economics	May provide stronger or different adsorption behavior for certain feeds and contaminants
Is one universally better?	No. The appropriate grade depends on feedstock chemistry, contaminant profile, dosage, filtration and required finished-product quality.

Values shown are typical reference properties and should not be treated as guaranteed lot specifications. Confirm current manufacturer documentation and/or the applicable COA before final qualification.

Filtration, Product Retention & Process Economics

Bleaching-earth performance should be evaluated on more than contaminant removal alone. In edible-oil processing, the adsorbent becomes part of a spent filter cake, so filtration rate and retained oil can materially affect the economics of the treatment.

Process Variable	Why It Matters
Adsorbent dosage	Higher dosage can increase treatment capacity but also increases spent-cake volume and potential product retention.
Contact conditions	Temperature, mixing and residence time affect adsorption and process consistency.
Filtration rate	Influences cycle time and production throughput.
Cake permeability	Affects pressure requirements and filtration productivity.
Product retention	Oil retained in the spent cake represents lost finished product.
Finished quality	Treatment should meet the actual color and contaminant specification without unnecessary over-treatment.

Questions & Answers

What is Pure-Flo® B80?

Pure-Flo® B80 is a naturally active Oil-Dri bleaching-earth product used in compatible edible-oil and liquid-purification processes. Its mineral activity is provided without mineral-acid activation.

What makes B80 “naturally active”?

B80 relies on the intrinsic surface characteristics of its mineral structure rather than mineral-acid activation to provide bleaching and adsorption activity.

What impurities can B80 help reduce?

Depending on the feed and treatment conditions, B80 can be evaluated for color bodies, residual soaps, phospholipid-related impurities, selected trace metals and other compatible refining contaminants.

Is B80 acid activated?

No. B80 is positioned as a naturally active bleaching-earth grade rather than a mineral-acid-activated clay.

Is naturally active clay better than acid-activated bleaching earth?

Neither is universally better. A naturally active grade may provide a favorable balance of purification, filtration behavior and product retention in one process, while an activated grade may provide stronger contaminant removal in another. Representative process testing is the best comparison.

What is the difference between B80 and B81?

Both belong to the Pure-Flo® oil-purification family, but they should not be assumed to be interchangeable. Compare their current manufacturer specifications, surface chemistry, acidity, particle-size distribution, filtration behavior and performance in the actual feedstock.

When should Select 350 or Select 450 be considered instead?

Select 350 and Select 450 are more naturally positioned for selective feedstock pretreatment where contaminants such as soaps, trace metals and phosphorus-related impurities are important to downstream processing. Selection should be based on the actual feed and treatment objective.

See our Biodiesel Feedstock Pretreatment guide for additional context.

Is B80 suitable for edible-oil processing?

B80 is positioned for compatible edible-oil refining applications. Application-specific regulatory, quality and documentation requirements should still be confirmed for the exact supplied product before use.

What is the typical lead time and minimum order?

The currently listed vendor minimum is 908 kg in supersack format, with a typical lead time of approximately 1–2 weeks subject to confirmation at quotation.

What documentation is available?

Manufacturer SDS, TDS and lot-specific COA information may be available. Regulatory or application-specific documentation should be requested before purchase when it is required for qualification.
