Soap and detergent can mix, in the use of MSG, iodized salt, fluoride toothpaste, what issues should pay attention to, talk about some personal views below.

Therefore, there is no so-called “acid-base neutralization”. The main component of soap The high-grade fatty acid sodium and hard water, calcium and magnesium ions combine to form a precipitate and affect the detergency, and detergent
