What is suspension concentrate?
Suspension concentrate (SC) formulations are liquid products such as fertilizers, pesticides and other agri-chemicals that have active ingredients (small solids) dispersed in water. They are more effective than emulsified concentrate (EC) and wettable powder (WP) formulations due to the fact that a stable SC must have active ingredients that remain insoluble under all temperature conditions. They are most commonly made by taking a solid active ingredient that does not dissolve in water or oil and impregnating onto, or combining it with, a substance such as clay. This is often done in a spray dryer. The solid mixture is then ground to a fine powder through milling and suspended in a small amount of liquid, usually water through a mixing process. Common ingredients include wetting agents, dispersants, viscosity modifiers (thickeners) and preservatives.

SC’s are quick to dry and are practically invisible and give a great residual effect which may last between 1 to 3 months long .
What happens when you dilute suspended concentrate?
When diluting a suspended concentrate in water, the suspension aids also get diluted; as a result, the solids can then settle quickly to the bottom of the mix tank. Suspended concentrates require a lot of shaking and agitation to prevent the active ingredient from settling.
Why is a suspended concentrate fluid thick?

How is suspension given?
Suspension dosage forms are given by the oral route, injected intramuscularly or subcutaneously, instilled intranasally, inhaled into the lungs, applied to the skin as topical preparations, or used for ophthalmic or otic purposes in the eye or ear, respectively. Some suspensions are available in a ready-to-use form that is, already distributed through a liquid vehicle with or without stabilizers and other additives. Other preparations are available as dry powders intended for reconstitution just before use with an appropriate vehicle. Generally, this type of product is a powder mixture containing the drug and suitable suspending and dispersing agents to be diluted and agitated with a specified quantity of vehicle, most often purified water.
What are the characteristics of suspension?
Ideal features of suspension dosage form 1 The final product should be physically, chemically and microbiologically stable. 2 Pharmaceutical suspension should be aesthetically pleasing and should also have a pleasing odour, and taste. 3 Suspended particles should be small and uniformly sized in order to give a smooth, elegant product free from a gritty texture. 4 The product must remain sufficiently homogenous for at least the period between shaking the container and removing the required amount. 5 Suspensions must not be too viscous to pour freely from a bottle or to flow through a needle syringe (for injectable suspensions). 6 All the doses dispensed from a given multi-dose container should have acceptable uniformity of drug content. 7 The drug substance must not recrystallize and/or change its polymorphic form during storage. 8 Suspended particles should settle slowly and the sediment or creaming produced on storage, if any, should readily redisperse upon gentle shaking of the container. 9 Parenteral and ophthalmic suspensions should be sterilizable and syringable (for parenteral suspensions). 10 Parenteral suspensions should be isotonic and non‐irritating.

Water-miscible formulations
By far the most frequently used products are formulations for mixing with water then applying as sprays. Water miscible, older formulations include:
Other formulations
Other common formulations include granules (GR) and dusts (DP), although for improved safety the latter have been replaced by microgranules (MG e.g. for rice farmers in Japan ). Specialist formulations are available for ultra-low volume spraying, fogging, fumigation, etc. Very occasionally, some pesticides ( e.g.
What happens if SC is not properly structured?
If an SC is not properly structured, the formulation can breakdown resulting in solid particles settling to the bottom of the formulation. This leads to reduced shelf life stability and poor performance in the field. The inclusion of a rheology modifier helps overcome this issue by increasing the viscosity of the formulation, providing improved stability.
Why is it important to include a wetting agent in a milling process?
It is important to include a wetting agent as during the milling process, fresh surfaces are generated which are generally of non-polar nature and will flocculate together rapidly. This could lead to increased viscosity and even mill blockage. Including a wetting agent overcomes this as it replaces air and prevents agglomeration, allowing dispersants to perform. Wetting agents can also provide some dispersion.
Can adjuvants be added to spray tanks?
In the agrochemical industry, adjuvants can be incorporated into a formulation ( built-in / in-can adjuvant) or can be added separately into the spray tank alongside other agrochemical products.
