Casein Peptone Lecithin Polysorbate Broth is a specialized neutralizing medium used for microbiological testing of pharmaceutical, cosmetic, and personal care products containing antimicrobial preservatives. Each 300 mL bottle contains a nutrient rich casein peptone base supplemented with lecithin and 10% polysorbate 80. These neutralizing agents inactivate a wide range of disinfectants and preservatives that would otherwise inhibit microbial recovery during sterility or bioburden testing. Polysorbate also acts as an emulsifier, helping disperse oily or viscous samples such as creams, ointments, and lotions within the broth. This formulation ensures accurate detection of microorganisms in products where antimicrobial compounds may be present, making it widely used in pharmaceutical quality control and microbiology laboratories.
