  A detailed X-ray Soft Excess of the narrow-line Seyfert-1 galaxy Tonantzintla
S180 (Ton s180) present. The study used four XMM-Newton observations for period
from the year 2000 to the year 2016 taken from the XMM-Newton archive. Two
different models were used to treat the X-ray Soft Excess for each data
separately, the first model is power law component and the second one is two
black body components. We found that, for all observations, the spectra fitted
by using a power law component are poor and the output parameters much
different from the previous studies, this model unsuccessfully reproduces the
continuum shape of the spectrum, including the soft excess, of all observations
(Nh = 3.62 +-1020 cm^{-2} and photon index for the hard and soft bands are 3.31
and 1.57). The study proved that it can rely upon the two black body components
in treating X-ray Soft Excess of the narrow-line Seyfert-1 galaxy (Nh= 1.395 +-
10^20 cm^{-2} and The temperature of the two black-body components (KT) are
0.075 and 0.17 keV).
