Microbial testing of Surfactant
Generally surfactant contain 30 % to 50 % active matter and remaining water or other impurities.
I am thinking if surfactant contain water 50 to 70 % water so microbial testing is require or not ?
I checked generally surfactants specification does not contain microbial limit or testing.
I want to know that why 30 to 50 % surfactant does not contaminate or microbial testing not require.
