Did you know bath bombs were invented by Mo Constantine one of the founders of Lush cosmetics in 1989? Bath bombs as we know today are a great addition to the bathing experience – adding fiz, a pop of colour and sweet smells! 

Made from a blend of dry ingredients: sodium bicarbonate, citric acid and water, the mixture can be tightly compressed into any chosen mould.

So what’s the science behind the fizz? 

As long as the mixture remains dry, nothing will happen… However, if the mixture comes into contact with water the chemicals dissolve, causing the citric acid (C6H8O7) to react with the sodium bicarbonate (Na2CO3).

This reaction creates sodium citrate (Na3C6H5O7) and carbon dioxide (CO2). These are the bubbles and fizz that we see immediately after. 

Bath bombs have many benefits, including balancing the bodies’ PH, flushing out toxins, softening the water and relaxing muscles.
