Salts and Esters

Some products come as salts and esters. The main difference is that Salts are soluble in water and thus require less agitation to keep them in solution, while Esters come as emulsifiable concentrates and constant need agitation to keep them in suspension.

Class exercise:
In one glass of water, add salt and mix to represent a “water soluble” – let stand. To another glass of water, add oil and mix to represent an “ester” – let stand

What happens to the “ester” with time. What does that mean for product uniformity and application?
