Bacteria is made up of both good (probiotic) and bad (Pathogens) and should remain in a microbial balance that is in favour of good bacteria. It is only when this balance starts to increase on the pathogen side that problems such as bacterial infections start to occur. Probiotics are naturally sourced from plants and are used in their natural chemical free state to help keep the balance in check. All ingredients are vegan and animal cruelty-free, non-polluting and biodegradable. They do not contain any dangerous substances, chemicals, carcinogens or toxins. This makes them completely safe for long term use by cleaning operatives.
