Which among the following is NOT a feature of adipocere formation?

Adipocere has a offensive rancid or an unpleasant sweetish smell. It occurs as a result of hydrolysis and hydrogenation of preexisting fats into higher fatty acids which later combines with calcium and ammonium ions to form soluble soap which resists putrefaction.
