Fatty Acid Esters are a type of ester that result from the combination of a fatty acid with an alcohol. When the alcohol component is glycerol, the fatty acid esters produced can be monoglycerides, diglycerides, or triglycerides. Dietary fats are chemically triglycerides.
- Glycerol Esters of Fatty Acids occur as colorless to brown powders, flakes, coarse powders, or granular or waxy lumps, or are a colorless to brown semi-fluids or liquids. They are odorless or have a characteristic odor.
- Biodiesels are typically fatty acid esters produced by the transesterification of vegetable fats and oils which results in the replacement of the glycerol component with a different alcohol.
No health benefits.
Generally biodegradable and most are nontoxic chemicals with very low skin and eye irritation. They are usually considered safe for humans and the environment.
