Sodium chloride

From PyroGuide

Formula: NaCl

Synonyms: Common salt, halite, table salt,

Description: Sodium chloride is used in pyrotechnics as delay agent in a few glitter formulas, but besides that, it is hardly ever used, since it is very hygroscopic. It is white or colourless solid in the form of crystals or powder.

Hazards: If inhaled it may cause mild irritation to the respiratory tract. Ingestion in very large can cause vomiting, diarrhoea, and prostration. Dehydration and congestion occur in most internal organs. Hypertonic salt solutions can produce violent inflammatory reactions in the gastrointestinal tract. Skin Contact may irritate damaged skin; absorption can occur with effects similar to those via ingestion. Eye Contact causes irritation, redness, and pain.

Sources: Sodium chloride can be purchased almost anywhere.
