Abstract
A polythiol composition according to exemplary embodiments includes at least two different polythiol-based compounds, wherein a peak area (%) of the polythiol compound represented by C8H18S6, which is measured through a high performance liquid chromatographic (HPLC) analysis graph obtained at a wavelength of 230 nm, ranges from 0.90% to 1.30%. By controlling the sub-polythiol compound, an optical product having excellent transmittance and optical properties can be manufactured.
