TYPES OF WATER USED IN PHARMACEUTICAL INDUSTRY THEIR INTENDED USE, PH AND PURITY

Sanitalk 

Here are 10 types of water commonly used in the pharmaceutical industry, along with their key characteristics:

1.Purified Water (PW):

Intended use: general manufacturing and cleaning purposes, raw material for other types of water

Purity: purified to remove impurities and contaminants such as bacteria, viruses, and minerals

pH: typically around 7.0, neutral

2.Water for Injection (WFI):

Intended use: solvent for the preparation of parenteral drugs

Purity: highly purified to meet strict specifications for purity and endotoxin levels

pH: typically between 5.0 and 7.0

3.Sterile Water for Injection (SWFI):

Intended use: diluent or solvent for parenteral drugs

Purity: highly purified and sterilized to be free of bacteria and other contaminants

pH: typically between 5.0 and 7.0

4.Sterile Water for Inhalation (SWFI):

Intended use: inhalation solution for respiratory diseases

Purity: highly purified and sterilized to be free of bacteria and other contaminants

pH: around 5.0

5.Bacteriostatic Water for Injection (BWFI):

Intended use: diluent for injectable drugs

Purity: highly purified and contains a bacteriostatic agent, such as benzyl alcohol or methylparaben, to prevent bacterial growth

pH: around 5.0

6.Sterile Water for Irrigation (SWFI):

Intended use: irrigation and lavage of body cavities, wounds, and surgical sites

Purity: highly purified and sterilized to be free of bacteria and other contaminants

pH: typically between 5.0 and 7.0

7.Sterile Normal Saline (SNS):

Intended use: diluent for parenteral drugs, wound irrigation, and hydration therapy

Purity: highly purified and sterilized, contains 0.9% sodium chloride

pH: typically between 4.5 and 7.0

8.Sterile Lactated Ringer's (LR):

Intended use: diluent for parenteral drugs, fluid resuscitation, and hydration therapy

Purity: highly purified and sterilized, contains sodium chloride, potassium chloride, calcium chloride, and sodium lactate

pH: typically between 6.0 and 7.5

9.Sterile Normal Saline with Dextrose (DNS):

Intended use: diluent for parenteral drugs, hydration therapy, and as a source of glucose

Purity: highly purified and sterilized, contains 0.9% sodium chloride and 5% dextrose

pH: typically between 4.5 and 7.0

10.Sterile Water for Injection with Dextrose (DW):

Intended use: diluent for parenteral drugs, hydration therapy, and as a source of glucose

Purity: highly purified and sterilized to be free of bacteria and other contaminants, contains 5% dextrose

pH: typically between 3.5 and 6.5

In summary, different types of water used in the pharmaceutical industry have different intended uses, levels of purity, pH, and sterilization requirements. The type of water selected depends on the specific needs of the application.
