Paraben - Wikipedia

Parabens are a class of widely used preservatives in cosmetic and pharmaceutical products. Chemically, they are a series of parahydroxybenzoates or ,esters, of parahydroxybenzoic ,acid, (also known as 4-hydroxybenzoic ,acid,).Parabens are effective preservatives in many types of formulas. These compounds, and their salts, are used primarily for their bactericidal and fungicidal properties.

Surfactant - Wikipedia
Surfactant - Wikipedia

Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.. The word ",surfactant," is a blend of surface-active agent, coined c. 1950.. Agents that increase surface tension are "surface active" in ...

Amines or Esters; Which Should You Use?
Amines or Esters; Which Should You Use?

Plants are more likely to quickly absorb ,esters,, as amines are more water soluble. Once the chemical is absorbed into the plant (either ,amine, or ester), it is converted to the active ,acid,, which in turn injures or kills plants that are susceptible to the respective herbicide. As we all know, correct timing is crucial for acceptable weed control.
