its names : Sodium bicarbonate, sodium hydrogen carbonate (chemical name), Vichy salt (Belgium), baking soda (United States), petite vache or soda à pâte (Quebec).
Description: Baking soda is a very popular product, present in millions of homes around the world. It has many uses (health, household, beauty, gardening and gastronomy) and its properties are very versatile (deodorant, fungicide, alkalizer, stain remover, cleaner, etc.). It is a leavening agent used in baking powder. It is also one of the oldest natural remedies in the world to protect the body against various diseases.
Caution! Baking soda should not be confused with caustic soda, which is extremely corrosive and very dangerous, nor with soda crystals.
Technical characteristics: Baking soda is a white, odourless powder, obtained by a process that combines two natural mineral raw materials: salt (rock salt) and limestone (blanc de meudon) to form sodium carbonate. It is non-toxic, non-flammable, biodegradable, ecological and economical.
Storage: Baking soda has an unlimited shelf life. However, it must be kept in its original, well-closed packaging, away from heat and humidity, and out of the reach of children. Tip: If you want to know if your bicarbonate is still usable, put some white vinegar in a bowl and add a pinch of bicarbonate; if a chemical reaction occurs, it means that your bicarbonate is still good!
Compatibility: Do not use on aluminium or waxed surfaces (risk of staining).
Do not use on wool and silk as the bicarbonate could destroy the fibres.
Precautions for use: Do not mix baking soda with vinegar in a closed bottle! The formation of foam and CO2 would increase the pressure; this reaction would cause the cap to pop off and propel the bottle up to 50 metres,
Contra-indications: internally, baking soda is not recommended for pregnant women, for people suffering from heart failure, high blood pressure (because of its salt content) and for children under 5 years old.
