A method of reducing the amount propylene chlorohydrin produced in a reaction to make a hydroxypropylated/crosslinked starch comprising removing residual propylene oxide from alkaline slurry. The residual propylene oxide is removed by the dewatering the alkaline slurry or by washing the starch in slurry at a pH of around 10. The starch is then neutralized in an acid solution and recovered from the second slurry and may or may not be washed, depending on whether the slurry while at pH around 10 to make a hydroxypropylated/crosslinked starch having less than 1 ppm propylene chlorohydrin.
