Accelerated testing CIPAC MT 46 Stability tests at elevated temperatures are designed to increase the rate of chemical degradation or physical change cioac a product.

Wet sieve analysis determines the quantity of particles in a formulation collected on a screen after dilution in water. The physical state is described in qualitative terms such as solid, liquid, suspension etc. 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.

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 mmt ensure water soluble products dissolve readily and, when diluted, produce stable solutions without precipitation, flocculation etc.

Copyright Designed by Mario IT. Karl Fischer method is classic technique providing a reliable ccipac truly practical method for the determination of water content in raw materials and products. The test consists of following parameters: Liquid formulations capsule suspensions, emulsifiable concentrates, oil-in-water emulsions, microemulsions, soluble concentrates, suspension concentrates may be adversely affected by storage at low temperature.

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. We also perform analyses of products supporting agrotechnical procedures, i. 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. Our analytical chemists study physicochemical properties to the extent required for registration and requirements of the specification FAO. Our modern laboratory ensures stable and durable formulations which meet even the most challenging customer requirements. 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.

Physical-chemical properties

If required, new analytical methods are developed and validated in accordance with SANCO regulations. Accelerated testing involves extrapolations from higher to lower temperatures and from shorter to longer storage periods. 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.

The pH is measured directly in the formulation or in aqueous solutions, suspensions of products. 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.

Studies and Testings according to CIPAC-Methods

The density is measured by traditional methods hydrometer and pycnometer and by a modern density meter. This test demonstrates that the user can make use of the maximum amount of the product in the container and that an excessive amount of the material does not remain in the container.

Odour involves the use of descriptive terms e. 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 nt.

We create up-to-the-minute formulations which excel at putting the biological effects of active substances to maximum use.

Storage at low temperature may result in crystallisation of active constituent ssignificant changes in viscosity or phase separation of emulsions. The residue remaining on a sieve cipc determined after dispersion to ensure that no unacceptable residue remains, which can cause blockage of nozzles in application equipment.

The data are required to ensure that an acceptable proportion of the product is within an appropriate size range. 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.

Cold stability testing CIPAC MT 39 Liquid formulations capsule suspensions, emulsifiable concentrates, oil-in-water emulsions, microemulsions, soluble concentrates, suspension concentrates may be adversely 446 by storage at low temperature.

CIPAC-Methods

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. Our laboratory has the GLP certificate, which means that all defined standards for organisation, personnel, facilities, test and reference substances, work instructions, result reporting, and archiving are met.

Dilution stability is determined to ensure water soluble products dissolve readily and, when diluted, produce stable solutions without precipitation, flocculation etc. Suspensibility of water dispersible products e. 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.

To provide customers with flexibility we offer the possibility of working according to our own Standard Operating Procedures or on protocols supplied by customers.

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. The method is suitable for determining free acidity or alkalinity in technical or formulated pesticides.

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. We offer development and validation of analytical method.

Pourability CIPAC MT This test demonstrates that the user can make use of the maximum amount of the product in the container and that an excessive cipzc of the material does not remain in the container. The statement of GLP compliance guarantees the international recognition of test results. This means that we are fully authorised to carry out studies assessing the physicochemical properties of substances and mixtures.

Emulsifiability, re-emulsifiability and emulsion stability CIPAC MT 36 For products which form emulsions, emulsifiability, emulsion fipac and re-emulsifiability data are required to determine whether a product forms and maintains a stable emulsion. The density of a solid or liquid substance is defined as the mass of the substance occupying unit volume at a stated temperature.

Accelerated testing is performed at elevated temperatures mg an attempt to obtain information on the shelf life of a product in a relatively short time. The pH value of a liquid is measured by the pH meter. We offer among others, the following analyses Our laboratory has the GLP certificate, which means that all defined standards for organisation, personnel, facilities, test and reference substances, work instructions, result reporting, and archiving are met.

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 acidity or alkalinity is determined by titration with standard acid or alkali in the presence of methyl red.
