Pentaerythritol Tetraoleate (PETO) CAS 19321-40-5

Identity and physicochemical profile

Compare acid and saponification values in mg KOH/g and kinematic viscosity in mm²/s (cSt) at the same stated test temperature. Water content, hydroxyl value, color and pour point should be checked against the offered grade’s specification. We can provide quality-control information with the applicable test methods, units and reporting basis for the agreed grade.

Applications and grade selection

PETO is evaluated as a synthetic ester base fluid, oiliness agent or lubricity component in hydraulic, gear and motor oils and metalworking fluids. Final performance depends on fatty-acid quality, residual functionality, additive package and the complete blend.

• Compare viscosity at the actual operating temperatures, not only one room-temperature value.
• Evaluate hydrolytic and oxidative stability, lubricity, elastomer compatibility and low-temperature flow in your finished formulation.
• Biodegradability, fire-resistance or environmentally acceptable lubricant claims require supporting test data for the exact grade and final product.

Glycerol Trioleate is an oleate ester based on glycerol rather than pentaerythritol. It provides a related ester comparison for lubricant development; compare the grade’s viscosity and formulation performance before considering substitution.

Storage and handling

Store sealed in a dry, ventilated area away from excessive heat, moisture and incompatible materials identified in the SDS. Limit prolonged air and water exposure where oxidation or hydrolysis control is important, and mix bulk material before representative sampling when required.

Safety, documentation and procurement

Use the current SDS for PPE, spill response, transport and disposal. For a quotation, share your intended application, quantity and destination. If known, include the viscosity grade and test temperatures, acid-value and water limits, preferred package or a reference specification.

For emulsification or solubilization in a lubricant formulation, review PEG 400 Dioleate and PEG 600 Dioleate as PEG-based oleate ingredients with different PEG grades. Glyceryl Monooleate can be evaluated for boundary lubricity and co-emulsification. These formulation roles differ from PETO’s ester base-fluid role; compare grade specifications and validate the complete formulation before substitution or combination.
