Definitions for "Esters"
Keywords:  fruity, alcohol, acetate, cooch, methyl
Compounds formed by reactions of organic acids with alcohols. For example, some esters used in cosmetics are emollients (skin soothers and softeners) and are designed to spread easily and penetrate our skin effectively. They tend to resist rancidity better than natural oils, thus their common use in products.
A group of chemicals resulting from the combination of an acid and an alcohol.
Methyl and ethyl esters produced from any vegetable (hemp, corn, soybean, sunflower) or tree (almond, walnut, palm, coconut) oils, animal fats (beef tallow), used oils (recycled fryer oils) or other fat sources from organic compounds. Esters are formed by combining an acid with an alcohol and eliminating the water. In the biodiesel reaction, esters are formed as a result of combining fatty acids and methanol or ethanol. See Transesterification.
A small specific portion of a structure of a molecule. All nail coating polymers, except for polishes, contain esters.
