Water dispersible granules (WG) are obtained by blending and agglomerating a ground solid active ingredient together with surfactants and other formulation ingredients, using water (or water + surfactants), as an agglomerating agent. A drying step is necessary to reduce moisture to a 1 – 2% range.

What are the advantages of water dispersible granules?

The benefits of a water dispersible granule are very similar to the benefits brought by wettable powders with the exception of one added benefit: reduced exposure risk. WDGs are easier to mix and measure and because they are less dusty, they are less of an inhalation hazard.

What is a dispersible concentrate?

DC Dispersible concentrate A liquid homogeneous preparation to be applied as a solid dispersion after dilution in water. DP Dustable powder A free-flowing powder suitable for dusting.

What is SL in formulation?

EC Emulsifiable concentrate. WP Wettable powder. SL Soluble (liquid) concentrate.

What does SC mean in pesticides?

The powder is suspended in a small amount of liquid to make the thick liquid formulation. Abbreviations used include “F” for flowable, “L” for liquid, and “SC” for suspension concentrate.

What’s the difference between soluble and dispersible?

What is the difference between water-soluble and dispersible? Water-soluble film completely dissolves, whereas dispersible film just breaks down into minute particles.

What are the types of formulations?

Types of Pharmaceutical Formulations

• Oral drugs.
• Parental Formulations.
• Topical Formulations.
• Modified release Formulations.
• Modified release Formulations.
• Modified release Formulations.
• Novel Drug Formulations.
• Oncological Formulations.

What does emulsifiable concentrate mean?

An emulsifiable concentrate (EC) is a liquid formulation that contains technical material, one or more organic water-immiscible solvents and an emulsifier (such as a surfactant). ECs are still one of the most common formulation types for pest control worldwide.

What is SC EC?

Suspension concentrate (SC) formulations consist of having a solid active ingredient dispersed in water. SCs have grown in popularity due to benefits such as absence of dust, ease of use and effectiveness when compared to other formulation types such as emulsifiable concentrate (EC) and wettable powder (WP).

What is SC and EC in insecticide?

Why do we dissolve disprin in water?

If you do continue to take the dispersible form it is important to start taking them dispersed in water because this means that the aspirin will not concentrate in one part of your stomach, which would be more likely to cause side effects.

What is granule liquid saturation and why is it important?

Granules liquid saturation, which is defined as the portion of pores within a granule that are filled with liquid, was shown to be a key factor in controlling granule coalescence. 34 Granule liquid saturation takes into account both the volume of available pores as well as the liquid volume as follows:

What happens when granules collide in the granulator?

As granules collide in the granulator they can either stick together (coalesce), resulting in growth, or they may bounce back with no increase in granule size. Layering is the term used for a special type of coalescence when fine particles or granules coalesce with larger ones.

What are storage granules in bacteria?

Storage granules are the major inclusion bodies found in some medically important bacteria. These granules are visible microscopically in the cytoplasm, with their composition depending on the bacterial species and growth conditions.

Is granule breakage necessary for the formation of inhomogeneous granules?

Granule breakage was associated with continuous exchange of particles, promoting homogeneous granules. Lack of granule breakage, however, promoted the layering mechanism of granule growth, leading to the formation of inhomogeneous granules (van den Dries & Vromans, 2002 ).
