Described herein are systems, methods and embodiments associated with the use of biomass for generating a preparation that can be used in manufacture of a personal care product. The described embodiments include collection of evidence of toxic cyanobacteria presence within biomass. Upon identification of biomass containing toxic cyanobacteria, embodiments describe processing of the biomass which will ultimately lead to the preparation. Thereafter, regardless of the initial presence of toxins, once the biomass is processed, the preparation can be safely used within a personal care product.
