Xylol FAQ: Common Questions Answered

A roundup of the questions people ask most about xylol (xylene), with short, plain answers. For the longer story on any of them, the fuller guides on this site go deeper.

Is xylol the same as xylene?
Yes. They are two names for one chemical, dimethylbenzene. “Xylol” is the older, traditional term; “xylene” is the modern one.

What is xylol used for?
Mostly as a solvent, for thinning oil-based paints and coatings, cleaning equipment, and degreasing. Industrially, its para isomer is also a feedstock for PET plastic and polyester.

Is xylol dangerous?
It is flammable, and its vapors are harmful in high or repeated doses. Used with good ventilation, gloves, and eye protection, it is safe for routine work.

Does xylol mix with water?
No. It is practically insoluble and, being lighter than water, floats on the surface.

Is xylol the same as paint thinner?
Not exactly. It can thin oil-based products, but it is stronger and slower to evaporate than a typical mineral-spirits paint thinner.

Can xylol thin latex paint?
No. It does not mix with water, so it will not thin latex or acrylic paints. Use it only with oil-based products.

How should xylol be stored and disposed of?
Store it cool, sealed, and away from flame and sparks. Never pour it down a drain; take used solvent to a hazardous-waste facility.

Where can I buy xylol?
In small amounts from hardware and paint stores, and in bulk from chemical distributors. It is sold under both the xylol and xylene names.
