### ⭐⭐⭐⭐ Is it safe for soap making?
*by A***A on 4 November 2019*

Hi, I've got your NaOH , Thank you . But the soaps I've made look different in color( particularly, my coconut oil soap always turns out to be white but now it's pinkish( I used the same oil, as before) So I really wonder : is your product pure and safe for soap making? What might cause that pink discoloration then? Thank you
