How important is the pH value of daily chemical products to the selection of preservatives?

Most preservatives are easy to exert their effectiveness in acidic and neutral environments, and their effectiveness is significantly reduced or even ineffective in alkaline environments, and they cannot achieve antiseptic effects, while quaternary salt preservatives are when the pH value is greater than 7 only valid. Changes in pH value cause changes in the cell membrane structure of microorganisms, thereby changing their permeability, thereby affecting the existence of preservative molecules (such as ionic or molecular forms), and many organic preservatives usually pass through microorganisms in molecular form. The lipid layer of the cell membrane. It is obviously inappropriate to choose Kasone when the pH value is greater than 9. At this time, sodium hydroxymethylglycinate or MIT will have the opportunity to choose.

XK - MIT methlisothiazolinone

Performance characteristics:

1. Methylisothiazolinone (MIT) is a broad-spectrum bactericidal preservative, that can effectively kill algae, bacteria and fungi.

2. The effective dosage is small, non-toxic and non-polluting, widely used, very easy to mix in various formulations.

3. After releasing the use concentration, it is easily biodegraded into non-toxic and non-polluting substances. Low toxicity, emission without residue.
