Chemical-Physical properties

Chemical and physical data are required to support the approval of an active substance and the authorisation of a formulated product.
For Plant Protection Products (PPPs), Biocides and Veterinary Medicinal products (VMPs) the chemical, physical and technical characteristics, along with their shelf-life, are intended to  show the safe and effective application of these products, according to their directions of use and that, during the storage, the formulation preserves the active substance and physical-chemical characteristics.
BioTecnologie BT staff is familiar with many types of formulations:
CS, DP,  DT,  EC, EW,  FS, GR, GW, ME, OD, SC,  SE,  SG, SL, SP, ST, WG,  WP,  WT and ZC

Storage Stability Studies
Cold Stability Testing  (0°C) according to CIPAC MT 39.3
Accelerated Storage Stability according to CIPAC MT 46.3
Shelf Life at Room Temperature

Analytical profile of batches of technical materials and formulated products
The analyses of at least five representative batches of production on an industrial scale recent and current of the active substance, is necessary to determine the content of the pure active substance, impurities, additives, and any other additional component. Data reported must include the results of the analysis of individual samples and a summary of these data, showing at least the minimum, maximum and average of each significant component.
Microbial Pest Control Agents (MPCA)
The analyses of at least 5 representative batches of production, or pilote-scale batches, is necessary to determine the content of the pure active substance, microbial contaminants and pathogens.The manufacturing processes have the potential of producing unwanted micro-organisms in addition to the desired MPCA which include pathogens, their associated toxins and other metabolic by-products of health concern.
BioTecnologie BT's laboratories are equipped with modern intruments to do tests on different technical grade active ingredients and formulations:
