Select 450 is a selective silicate adsorbent from Oil-Dri designed to reduce soaps, trace metals, and phospholipids in edible oils and biofuel feedstocks. It is commonly used as a pretreatment step to improve feed quality and support more efficient downstream bleaching, refining, and specification compliance.
Order minimum: 2 pallets (Pallet ≈ 40 × 25 kg bags).
- Pallet — 2–3: $3,829ea • 4+: $3,519ea

Where it fits
- Edible oils: removal of soaps, phospholipids, and metals that impact stability, color development, and refining performance.
- Biodiesel feedstocks: impurity reduction to support spec compliance and improve downstream processing performance.
- Pretreatment before bleaching: used ahead of activated clay to improve overall contaminant removal in challenging crude oils.
- Industrial oil purification: targeted cleanup where trace contaminants impact downstream performance.
Why Select 450
- Targets soaps, metals, and phospholipids that can be difficult to manage with clay alone.
- Useful as a pretreatment to improve feed quality before downstream bleaching and refining steps.
- Consistent filtration behavior for predictable throughput in common pretreatment setups.
- Broad feedstock compatibility across edible oils and biofuels processing.

FAQ
What does Select 450 remove?
Select 450 is designed to reduce soaps, trace metals, and phospholipids in edible oils and biofuel feedstocks.
When should I use Select 450 vs Select 350?
Both are selective silicate adsorbents for soaps, metals, and phospholipids. Select 450 is often chosen when you want a stronger pretreatment option for more challenging feedstocks. Bench trials are the best way to confirm the most efficient dose and grade.
What is the minimum order?
The order minimum is 2 pallets. Each pallet is approximately 40 × 25 kg bags.
Is freight included in the pallet price?
No. Freight is calculated at checkout using live LTL rates. Liftgate and appointment options can be selected during checkout.
What documentation is available?
SDS, TDS, and COA are available with all orders. If you need documentation in advance, request it through our documentation page.
