Commonly used bactericidal and algicides can be divided into two categories: oxidizing bactericidal and non-oxidizing bactericidal and algaecides.

Isothiazolinone biocide can inhibit bacteria, fungi and molds at the same time, and does not produce drug resistance; it has excellent physical and chemical compatibility.Although isothiazolinone is acidic, it is applicable in a wide range of pH values, and it can maintain a high even under alkaline conditions. Stability; it can be naturally degraded into non-toxic substances without causing environmental pollution.

BIT-20 biocide is a broad spectrum microbicide. To kill many bacteria, fungi and yeasts; the liquid with a lowest concentration of 0.1% will have a good antibacterial effect;

The main industrial preservatives used in liquid detergents are including 1,2-benzisothiazolin-3-one，Magnesium ion-protected isothiazolinones of CMIT/MIT 14%， Isothiazolinone with low magnesium ion content of CMIT/MIT 1.5%, MIT biocide; Benzalkonium Chloride etc.

The popular biocides of CMIT/MIT, Isothiazolinone, PCMX/ Chloroxylenol are widely used as biocide of soap liquid, hand sanitizer, laundry detergent etc.

Benzisothiazolinone, also called BIT. It is a broad spectrum microbicide for the preservation of industrial water-based products against the attack of microorganisms. BIT 85% Powder containing 99% W/W 1,2-Benzisothiazolin-3-one.
