Physico-chemical Properties
These tests measure physical and chemical properties of substances. They are requisite together with toxicological and ecotoxicological properties for a reliable safety assessment of various chemical substances, pesticides, biocides etc. to human health and the environment, to help predicting toxicological or environmental hazards and behaviour.
The Physico-chemical testing represents an integral part of the standard information requirements and are necessary for the registration of chemical substances, pesticides, biocides etc....Read more...
OECD/EU-Methods
The OECD (Organisation for Economic Cooperation and Development) has developed standardized testing methods as a part of the registration of chemicals which are internationally accepted.
We provide test data for physicochemical properties including melting temperature, boiling point, relative density, vapour pressure, surface tension, water solubility and partition coefficient. Moreover, many further physico-chemical tests are available as well including granulometry, flammability, viscosity etc and screening tests for thermal stability (e.g. explosive properties) using differential scanning calorimetry (DSC), if required.

UN-Methods
The UN methods are needed for purposes of the CLP Regulation (EC) No. 1272/2008 and the Global Harmonised System (GHS) for the Classification and Labelling as well as the Transport of Chemicals.
The goal of the GHS is to identify the intrinsic hazards found in substances and mixtures and to convey hazard information about these hazards. The criteria for hazard classification are harmonized and now form an integrated hazard communication system (ST/SG/AC.10/30/Rev.6)

CIPAC-Methods
CIPAC's main objective is the standardization of methods (The CIPAC methods / Collaborative International Pesticides Analytical Council) for the analysis of pesticide products and physico-chemical tests for formulations. This standardization is achieved through the conduct of internationally recognized tests according to accepted procedures.
The CIPAC methods play an important role particularly for the registration and authorization of plant protection products. Depending on the formulation of the product, InterBioTox can perform the required method of analysis for your needs according to GLP compliance.
The analytical methods are mainly based on GC and HPLC techniques and are focused as well as to the physicochemical tests, which may consist of visual observations or of manipulations but, at present, are usually based on instrumental techniques.

FEA-Methods
Aerosol products are present in different industries including cosmetic, technical, household and many more. These products are subject to number of controls both at the pre-production, in-process and post-production stages.
FEA (European Aerosol Federation) has developed guidelines for aerosol testing to ensure a safe use. The following study could be applied by the laboratory of InterBioTox to Biocidal Products and Pesticides with spray applications
