Which one of the following ingredients does not constitute paint?

general-sciencechemistry

ATurpentine oil (thinner)
BPoly-hydroxy phenols (anti-skinning agent)
CThiourea (accelerator)
DTitanium dioxide (pigment)

Explanation

Paint is formulated from a thinner (turpentine oil), an anti-skinning agent (poly-hydroxy phenols) and a pigment (titanium dioxide, the standard white pigment). Thiourea is an accelerator used in rubber vulcanisation, not a paint constituent. Hence thiourea is the ingredient that does not constitute paint.
