Accelerated testing is performed at elevated temperatures in an attempt to obtain information on the shelf life of a product in a relatively short time. This test should be conducted with suspension concentrates, capsule suspensions and suspo-emulsions.
Stability tests at elevated temperatures are designed to increase the rate of chemical degradation or physical change of a product. This test is performed visually and organoleptically. Persistent foaming CIPAC MT 47 Persistent foam is a measure the amount of foam likely to be present in a spray tank or other application equipment following dilution of the product with water in accordance with the label instructions. Depending on the formulation type and packaging material, testing under standardised relative humidity and light exposure conditions may also be required.
Accelerated testing CIPAC MT 46 Stability tests at elevated temperatures are designed to increase the rate of chemical degradation or physical change of a product.
Our modern laboratory ensures stable and durable formulations which meet even the most challenging customer requirements. Our methods comply with the requirements of the European Union and with the principles of Good Laboratory Practice.
Liquid formulations capsule suspensions, emulsifiable concentrates, oil-in-water emulsions, microemulsions, soluble concentrates, suspension concentrates may be adversely affected by storage at low temperature.
Karl Fischer method is classic technique providing a reliable and truly practical method for the determination of water content in raw materials and products. The density is measured by traditional methods hydrometer and pycnometer and by a modern density meter.
The pH is measured directly in the formulation or in aqueous solutions, suspensions of products. Persistent foam is a measure the amount of foam likely to be present in a spray tank or other application equipment following dilution of the product with water in accordance with the label instructions.
The spontaneity of dispersion of water dispersible products eg water dispersible granules and suspension concentrates is determined to show the product is easily and rapidly dispersed when diluted with water. In liquid chromatography we use UV detector, fixed or variable wavelength, which includes diode array detector DAD and refractive index detector.
It is an important parameter for neat substances as well as for produced goods and must be controlled, especially in the chemical, pharmaceutical, petrochemical and food and beverage industries.
Suspensibility of water dispersible products e. Our objective is to minimise any adverse impact that our products might have on the environment. Our analytical chemists study physicochemical properties to the extent required for registration and requirements of the specification FAO. Definition of Good Laboratory Practice Good Laboratory Practice GLP embodies a set of principles that provides a framework within which studies are planned, performed, monitored, recorded, reported and archived.
We have the Mastersizer laser diffraction particle size analyzer which delivers rapid, accurate particle size distributions for wet dispersions. Dilution stability is determined to ensure water soluble products dissolve readily and, when diluted, produce stable solutions without precipitation, flocculation etc.
Wettability of solid products which are diluted for use e. Dispersion stability of suspo-emulsions CIPAC MT The result of this test shows if a sufficient amount of active constituent is homogeneously dispersed in suspension and emulsion in the spray liquid, to give a satisfactory and effective mixture during spraying.
For water dispersible products, a wet sieve test must be conducted. This test is applicable to wettable powders, suspension concentrates, water dispersible granules, aqueous capsule suspensions, dispersible concentrates, suspo-emulsions, water soluble granules and water soluble powders.
Our laboratory specialises in — The determination of physical and chemical properties — Content of active substance The tests are carried out in accordance with CIPAC methods. Particle size distribution CIPAC MT The nominal size range for solid materials for direct application eg dustable powders and granules and solid materials for dispersion in water eg wettable powder and granules must be determined. The density meter is the most accurate density meter on the market and is ideal for numerous fields of application and successful continuous operation in the laboratory.
The method is suitable for determining free acidity or alkalinity in technical or formulated pesticides.
Studies and Testings according to CIPAC-Methods
On the basis of the inspection which was held in by Bureau for Chemical Substances confirmed that Pestila Sp. The density of a solid or cipaf substance is defined as the mass of the substance occupying unit volume at a stated temperature.
The test consists of following parameters: Your submission has been received! The acidity or alkalinity is determined by titration with standard acid cipzc alkali in the presence of methyl red. Copyright Designed by Mario IT. Accelerated testing involves extrapolations from higher to lower temperatures and from shorter to longer storage periods.
The dry sieve test is designed to determine the particle size distribution of dustable powders and granules that are intended for direct application, to ensure acceptable application. The pH value of a liquid is measured by the pH meter.
Emulsifiability, re-emulsifiability and emulsion stability CIPAC MT 36 For products which form emulsions, emulsifiability, emulsion stability and re-emulsifiability data are required to determine whether a product forms and maintains a stable emulsion. Storage at low temperature may result in crystallisation of active constituent ssignificant changes in viscosity or phase separation of emulsions. Water content plays a significant role in many chemical processes and affects cilac performance, organoleptic properties and stability.
We offer development and validation of analytical method.
These studies are undertaken to generate data by which the hazards and risks to users, consumers and third parties, including the environment, can be assessed for pharmaceuticals, agrochemicals, veterinary medicines, industrial chemicals, cosmetics, food and feed additives and biocides.
Dilution stability CIPAC MT 41 Dilution stability is determined to ensure water soluble products dissolve readily and, when diluted, produce stable solutions without precipitation, flocculation etc. Odour involves the use of descriptive terms e. The residue remaining on a sieve is determined after dispersion to ensure that no unacceptable residue remains, which can cause blockage of nozzles in application equipment.
We also perform analyses of products supporting agrotechnical procedures, i. We reduce any risks that might occur during transport, storage or utilisation, by paying special attention to the selection of appropriate components at the formulation stage. Something went wrong while submitting the form: For products which form emulsions, emulsifiability, emulsion stability and re-emulsifiability data are required to determine whether a product forms and maintains a stable emulsion.
