Is thinner oil based?

Other than the price, the differences between the two solvents are subtle: Both are petroleum products. Both can be used to thin oil-based paints and varnishes and to clean paintbrushes. Paint thinner is mineral spirits, but in a less refined form.

What can I use instead of lacquer thinner?

In terms of toxic solvents, ethyl alcohol (sold as denatured alcohol), isopropyl alcohol, rubbing alcohol, acetone, and mineral spirits or paint thinner are the least toxic. Solvents such as methyl alcohol, lacquer thinners, toluene, xylene, and turpentine can often be substituted for these toxic substances.
