Main components of beeswax

Beeswax is a complex organic compound. The main components of beeswax are esters, fatty acids and hydrocarbons synthesized from higher fatty acids and monohydric alcohols.

1, esters

Fatty acid esters include monoesters and hydroxy esters, with a content of 70%-75%. Among the monoesters, there are 23% mellyol palmitate, 2% lacquer palmitate, 12% mellyol cerate, and 12% mellyol pyrogallic acid. The hydroxy esters include hydroxy palmitate wax alcohol ester 8%-9%, diester 9%-95%, and acid ester 4%-4.5%.

2, Fatty acid

Free fatty acid content is 10%-15%; saturated fatty acid 9%-11%, of which ceric acid 3.3%-4.4%, wood tar oil acid 1%-1.5%, melitic acid and montanic acid 2%, folic acid 1.3% -1.5%, pyrogallic acid 1.5%, etc.

3, sugar

The carbohydrate content is 10%-16%. The saturated hydrocarbons are most prominent with 15-31 carbon atom chains, among which 25 alkanes are 0.3%, 27 alkanes are 0.3%, 29 alkanes are 1%-2%, and 31 alkanes are 8%-9%; no Saturated hydrocarbons are mainly 30 alkanes, accounting for 2.5%.

4. Other ingredients in beeswax

Beeswax contains fatty acid cholesterol esters, colorants (mainly 1-3 double hydroxide flavonoids), ω-myristylactone, free fatty alcohols, etc. In addition, beeswax also contains a small amount of water and minerals. The ash content of beeswax contains 80%, 13%, and 7% of carbon, hydrogen, and oxygen respectively.
