Description: A toiletry item used in a bath, it causes water to fizzle. It was invented in 1989 by co-founder Mo Constantine. Working from her shed in Dorset, Constantine was inspired to create her 'Aqua Sizzlers' (which would later become 'Bath Bombs') after becoming intrigued by tablets. While her first attempts looked much like Alka-Seltzer tablets, Mo and her husband Mark Constantine quickly began experimenting with a range of molds and ingredients.
The original bath bomb was patented by the Constantines in 1989 under the brand name 'Cosmetics To Go'. However, when the company went into administration, the couple lost the patent. In 2014, a new patent was issued to Cosmetic Warriors LTD (the proprietor of the Lush Cosmetics trademark), protecting the process of creating a bath bomb with distinct layers.
