Excebiol Biodegradable Lubricant Base Oil [Development Product]

Poly alkylene glycol-based lubricant that combines water solubility, biodegradability, and lubricity.

Sanyo Chemical’s Biodegradable Lubricant Base Oil. Here is what makes “EXCEBIOL” so great!

1. Excellent water solubility and biodegradability

The EXCEBIOL series has excellent water solubility, so it mixes easily with water and does not separate over time, maintaining a uniform liquid state.
The EXCEBIOL series is biodegradable, making it environmentally friendly even in the event of leakage into the environment.

2. Excellent lubricating function

The “EXCEBIOL” series covers a wide range of viscosities with a rich lineup, enabling the selection of the grade that best suits various applications.

3. Extensive lineup covers a wide range of viscosities

The EXCEBIOL series has excellent water solubility, so it mixes easily with water and does not separate over time, maintaining a uniform liquid state.

“EXCEBIOL” is a poly alkylene glycol-based lubricant base oil that is friendly to people and the environment.

Potential Applications

EXCEBIOL” is biodegradable and can be used as a lubricant base in various fields to reduce environmental impact in case of accidental leakage.

1. Marine energy-related

Lubricant base for wind turbine generators, etc.

2. Ship related

Lubricant base for power sources such as marine screws, etc.

3. Agricultural and Construction Machinery

Lubricant base for agricultural and construction machinery, etc.

4. Molding and processing

Mold release agents, etc., in the molding and processing field

Main properties of “EXCEBIOL”

EXCEBIOL has superior water solubility and biodegradability compared to existing base oils such as ester, mineral, and PAO base oils and exhibits comparable lubricating properties.

Water solubility of “EXCEBIOL”

“EXCEBIOL” easily mixes with water and maintains a homogeneous state after shaking.

Table 3. Evaluation of water solubility of “EXCEBIOL”

<Test Method>
EXCEBIOL water solubility evaluation test:

A 2ml sample of each grade of EXCEBIOL was weighed into a test tube, and 2ml of water was added gently.
(For “EXCEBIOL DE-1000,” 3 ml of water was added to 1 g of sample.)
The sample was shaken first gently and then finally vigorously to check its compatibility with water.
After the specimens were shaken, they were allowed to stand for 24 hours, and it was observed that there was no separation of the liquids over time.

[The photographs in the table above show the appearance before shaking and after 24 hours of standing.］

Comparison test:
Ester/mineral oil/PAO base oil was tested similarly, and liquid separation from the water was observed over time.
