Overview
Pure-Flo® Select 450 by Oil-Dri is a finely divided selective silicate adsorbent positioned for targeted reduction of soaps, phospholipid-related impurities, selected trace metals and other polar contaminants in compatible edible-oil, biodiesel and renewable-feedstock processing applications.
Select 450 is most naturally evaluated as a pretreatment adsorbent before bleaching, filtration, conversion or downstream refining. Rather than serving primarily as a broad decolorizing clay, it is intended to help reduce process-sensitive impurities that may affect feedstock quality, filtration, catalyst exposure, downstream conversion or finished-product specifications.
For process-level guidance, see our Adsorbents for Biodiesel Feedstock Pretreatment , Bleaching Clays & Purification Adsorbents , and Adsorbents for Oil Purification & Refining .
Minimum order: 2 pallets.
- 2–3 pallets: $3,829 per pallet
- 4+ pallets: $3,519 per pallet
Bagged pallet configuration: 40 × 50 lb (22.68 kg) bags — 2,000 lb (approximately 907 kg) net per pallet.
Bulk format: 2,000 lb (approximately 907 kg) supersack available by request. Contact Sorbents Direct for current pricing and availability.
Freight is calculated at checkout using live LTL rates for eligible configurations.
Where Pure-Flo® Select 450 Fits
- Biodiesel feedstock pretreatment: Treatment of compatible vegetable oils, recycled oils and other feedstocks where soaps, phosphorus-related impurities, selected metals or other process-sensitive contaminants need to be reduced before downstream conversion.
- Renewable-feedstock conditioning: Pretreatment of fats, oils and greases ahead of filtration, bleaching, refining or fuel-processing steps.
- Edible-oil pretreatment: Targeted reduction of soaps, phospholipid-related impurities, selected trace metals and other polar contaminants before downstream refining.
- Pretreatment before bleaching: Selective contaminant reduction before a broader bleaching-earth step.
- Dry-treatment process evaluation: Adsorptive cleanup in compatible systems where selective solids treatment is evaluated alongside or in place of conventional washing steps.
- Industrial oil purification: Targeted treatment where feed impurities affect downstream processing, catalyst protection, filtration or finished-product quality.
Select 450 is a selective pretreatment media - not a general bleaching clay.
Traditional bleaching-earth products such as Pure-Flo® B80, Supreme B81 and Supreme 55 are generally positioned around broader color reduction and oil polishing.
Select 450 is more naturally positioned upstream, where targeted contaminant reduction is important to the next process step.
Why Choose Select 450?
- Selective impurity reduction: Positioned around soaps, phospholipid-related contaminants, selected metals and other compatible polar impurities.
- Biodiesel & renewable-feedstock relevance: Particularly useful to evaluate where feedstock contaminants can affect downstream conversion or finished-fuel quality.
- Pretreatment utility: Can be used before bleaching earth, filtration or conversion.
- Fine powdered form: Provides close contact with the treated oil or feedstock during mixing.
- Integrated-treatment potential: Allows processors to optimize selective pretreatment and subsequent bleaching-earth dosage together.
- Industrial packaging: Available in bagged pallets and 2,000 lb supersacks.
- Qualification support: Current manufacturer documentation can be requested before purchase.

What Can Select 450 Help Reduce?
| Treatment Target | General Role | Important Considerations |
|---|---|---|
| Residual soaps | Core selective-pretreatment objective | Incoming concentration and feed chemistry influence the required dosage. |
| Phospholipid-related impurities | Relevant pretreatment target | Measure residual phosphorus-related contaminants when downstream specification or catalyst sensitivity is important. |
| Selected trace metals | May support targeted reduction | Performance depends on the specific element, feedstock chemistry and treatment conditions. |
| Other polar impurities | Application dependent | Adsorption should be confirmed against the actual contaminant profile. |
| Color bodies | Not the primary positioning | Broad color reduction is generally more naturally associated with a bleaching-earth treatment step. |
Important: Select 450 should be selected around the actual feed analysis and downstream requirement rather than assumed to remove all feedstock impurities equally.
How Select 450 Fits Into a Treatment Process
| Process Stage | Potential Role |
|---|---|
| 1. Incoming oil or feedstock | Characterize soaps, phosphorus-related impurities, selected metals, moisture, acidity, color and other relevant feed properties. |
| 2. Select 450 pretreatment | Target compatible soaps, phospholipid-related contaminants, selected metals and other polar impurities. |
| 3. Bleaching-earth treatment | Where required, follow with broader color reduction, chlorophyll treatment and oil polishing. |
| 4. Filtration | Remove spent adsorbent and retained contaminants from the treated feedstock. |
| 5. Downstream refining or conversion | Continue processing toward the required edible-oil, biodiesel or other finished-product specification. |
The appropriate process sequence depends on feedstock chemistry, treatment equipment, contaminant profile and downstream requirements.
For biodiesel and renewable feedstocks, upstream impurity control can be the real treatment objective.
Color may be visually obvious, but soaps, phosphorus-related contaminants and selected metals can be more important to downstream processing. Select 450 is most useful to evaluate when those process-sensitive contaminants are the actual bottleneck.
Select 450 vs. Bleaching Earth
| Selection Factor | Pure-Flo® Select 450 | Traditional Bleaching Earth |
|---|---|---|
| Primary role | Selective feedstock pretreatment | Broader bleaching and oil polishing |
| Typical treatment emphasis | Soaps, phospholipid-related impurities, selected metals and other polar contaminants | Color bodies, chlorophyll, oxidation products and broader compatible impurities |
| Typical process position | Before downstream bleaching, filtration or conversion | Bleaching / polishing stage |
| Is Select 450 a direct replacement? | No. These media perform different treatment roles and may be complementary within the same process. | |

| Tamped density | 37.0 lb/ft³ | 43.0 lb/ft³ |
| Particle size | 62% passing 325 mesh | 62% passing 325 mesh |
| Which is better? | Neither should be assumed universally superior. Final selection should use current Oil-Dri guidance and comparative trials with the actual feedstock. | |
These comparison values are based on previously supplied product information and require confirmation against current Oil-Dri documentation.

Biodiesel & Renewable-Feedstock Pretreatment
Select 450 is particularly relevant to evaluate in biodiesel and renewable-feedstock systems where contaminants such as soaps, phosphorus-related impurities or selected metals may affect downstream conversion, filtration or finished-fuel requirements.
Feedstocks can vary substantially across refined vegetable oils, used cooking oils, animal fats and other renewable sources. A treatment dosage or grade selected for one feed should not be assumed to perform identically on another.
For process-level selection guidance, see: Adsorbents for Biodiesel Feedstock Pretreatment .
Application & Trial Guidance
Appropriate Select 450 dosage depends on feedstock, incoming soap content, phosphorus-related impurity concentration, selected metal profile, moisture, treatment temperature, mixing conditions, contact time, filtration equipment and downstream specifications.
- Begin with controlled bench trials using the actual oil or feedstock.
- Characterize the untreated feed before setting the treatment objective.
- Evaluate multiple Select 450 dosage rates rather than assuming one universal treatment level.
- When Select 450 is followed by bleaching earth, optimize both dosages together.
- Measure relevant contaminants before and after treatment.
- Evaluate filtration behavior, product retention and downstream performance along with contaminant removal.
- Confirm that treated material meets the actual downstream process or finished-product requirement.
No universal dosage is stated because the proper treatment rate should be established through process testing and current manufacturer guidance.

Questions & Answers
What is Pure-Flo® Select 450?
Select 450 is a finely divided selective silicate adsorbent positioned for pretreatment and targeted impurity reduction in compatible edible-oil, biodiesel, renewable-feedstock and industrial-oil processes.
What impurities does Select 450 target?
Select 450 is positioned around soaps, phospholipid-related impurities, selected trace metals and other compatible polar contaminants that can interfere with downstream processing.
Is Select 450 a bleaching clay?
It is more accurately positioned as a selective silicate adsorbent for targeted pretreatment. Traditional bleaching earth generally has a broader emphasis on color reduction, chlorophyll and oil polishing.
When should Select 450 be used before bleaching earth?
It may be evaluated where soaps, phosphorus-related impurities, selected metals or other polar contaminants need targeted reduction before broader bleaching or downstream conversion.
Can Select 450 be used in biodiesel processing?
Select 450 may be evaluated for pretreatment of compatible biodiesel feedstocks where process-sensitive impurities need to be reduced before downstream conversion or finishing.
What is the difference between Select 450 and Select 350?
Both products belong to the selective-adsorbent family. Select 450 has particularly strong current positioning around biodiesel and renewable-feedstock pretreatment, while Select 350 has broader selective pretreatment positioning. The most appropriate grade should still be established through current Oil-Dri guidance and representative process trials.
Is Select 450 stronger than Select 350?
Sorbents Direct does not currently have sufficient verified manufacturer documentation to make that claim. Differences in moisture, density or other physical properties do not by themselves establish adsorption superiority. Compare the products using the actual feedstock and target contaminants.
Should Select 450 replace B80, Supreme B81 or Supreme 55?
Not automatically. Select 450 is primarily positioned for selective pretreatment, while B80, Supreme B81 and Supreme 55 sit more naturally in the broad bleaching and polishing branch. They may be complementary rather than direct substitutes.
What dosage should I use?
There is no universal dosage. Establish treatment rate through controlled trials using the actual feedstock, contaminant profile, filtration system and downstream specifications.
What is the minimum order?
The current minimum order for published bagged-pallet pricing is two pallets, or 4,000 lb total.
