Volatile encapsulation application area

This leaves two basic formulation types to consider. The first is the capsulated suspension (CS) formulation. This formulation is used to deliver a version of the active ingredient that has a reduced toxicity, reduced volatility, or a reduced release rate. The agrochemicals application area is one of the key areas when encapsulation technology has yielded commercial products. The second category is tank mix additive (TMA). The TMA is not really a formulation type on its own, but is rather any material diat is added to a tank mix to aid or modify the action of the agrichemical, or die physical characteristics of the mixture(l). It can be in almost any form, and can function in one or more of a multitude of mechanisms. 

The introduction of encapsulation of volatiles, which 15 years ago saw very few publications, has now, by 2013, turned into a very active eld of applied research. Encapsulation or prolonged delivery of volatiles gives us more predictable and long-lasting effect of the compounds. The areas of application are very varied, and the industry using essential oils and terpenes foresees many prospects for new microencapsulated products. 

To lower the volatility, one needs to encapsulate the volatiles into a polymer matrix, utilize complex formation, use the covalent bonding to a matrix—to mention a few techniques. We therefore need to formulate the volatiles and take many of these techniques from areas where controlled release formulations have already been in use for many years. The area with the maximum number of applications of controlled release formulations is the field of drug delivery. In this area of research, there exists a large number of publications as well as a large number of patents where one can find inspiration for the formulation of programmed release of volatiles (Deasy, 1984). 

Since the introduction of the encapsulation of volatiles (essential oils/lower terpenes), the number of applications has multiplied. Encapsulation of volatiles gives us a more predictable and long-lasting effect of the products. The areas of applications are large and the industry of essential oils and terpenes foresee many prospects for microencapsulated products.
