Re: MSOP vs SSOP

 

Facial bleach of the old days is H2O2 + NH4 (Ammonia). The first world has fancy brand names but I am sure that you could find it in the stores. Here my aquarium group informs me that they buy ammonia to "fishless cycle" their tanks. So I guess it must be available in Vietnam too.

Here we use Javel (NaClO) has bleach.
