Sodium chloride (NaClcap N a cap C l𝑁𝑎𝐶𝑙) is a common chemical in New Zealand, naturally occurring in seawater and mineral deposits like the Lake Grassmere saltworks. It is a widely used mineral and chemical compound, essential for life and with applications in food, pharmaceuticals, and various industrial and personal care products across New Zealand.

Natural occurrence in New Zealand

Lake Grassmere:

New Zealand has solar salt production at Lake Grassmere, where salt is harvested from evaporation ponds to produce large mounds of sodium chloride crystals.

Seawater:

As sea salt, it is the primary mineral in ocean water, with New Zealand’s surrounding seas being a natural source.

Industrial and commercial uses

Pharmaceuticals:

High-purity “Pure Dried Vacuum” (PDV) salt is used in manufacturing products that need to meet pharmacopoeia standards.

Food and beverage:

It is used as a food seasoning and stabilizer. Calcium chloride, which is also a chemical, is often added to foods like cheese and canned goods to increase saltiness without adding sodium, as noted by NZ Chemical Suppliers.
Personal care:

It is used in products like body washes and soaps to improve texture and hardness.
Industrial:

It is used as an abrasive, thickener, and stabilizer in cleaning products.
Chemical analysis:

It is sold as a standard solution for calibration and testing in labs, such as those provided by Hach New Zealand.
