COMPOSITIONS COMPRISING FLEXIBLE PARTICLES, NON-IONIC SURFACTANT AND NON-IONIC CLOUD-POINT MODIFIER

摘要

A diagnostic or therapeutic composition comprising physiologically tolerable, diagnostically or therapeutically effective flexible particles and a physiologically tolerable non-ionic surfactant emulsifier in an aqueous dispersion medium, characterised in that said aqueous dispersion medium further contains a physiologically tolerable, non-ionic, water-soluble cloud-point modifier at a concentration such that the cloud point of said medium is above a temperature usable for steam sterilization.
