Definition of beeswax
It is obtained by melting and purifying the honey comb of Apis mellifera or Apis mellifera and other species
Geographical distribution of beeswax
Jamaica, Africa, Madagascar
How is beeswax prepared
How the wax is secreted
Yellow beeswax
Separation of the honey, honey comb is melted with hot water, residual honey dissolves, solid impurities sink, sieved, wax allowed to solidify in moulds
White beeswax
It is prepared from yellow beeswax, bleaching using chlorine, chromic acid, charcoal, potassium permanganate etc, or slow bleaching with sunlight, air and water
For slow bleaching
The melted wax is poured on a revolving cylinder to form ribbon strips which are exposed to sunlight and air. The strips are frequently moistened and turned till the outer surface is bleach
Characteristics of beeswax
It is a yellowish brown or yellowish white solid
It breaks with granular fracture
It is insoluble in water, slightly soluble in alcohol but soluble in chloroform and warm oils like turpentine
It has a characteristic odour(honey like odour
Chemical constituents of beeswax
Myricyl palmitate(myricin) {C15H31COOC30H61}, 80% making it the major constituent, and a little of
Myricyl stearate
Other constituents are
15% free cerotic acid{C26H53COOH}
Hydrocarbons cholesterol esters
Uses of beeswax
POP AND CLC
Plasters, ointments, polishes
Cosmetic creams, Lipsticks, candles
Clinical uses of beeswax
Beeswax + vegetable oil
Gives a mixture used to treat skin cracks
Mixture of CCOBT{Camphor, common salt, olive oil, beeswax and tallow is used for ulcer patients and for external tumor
Adulterants of beeswax
Paraffin, stearic acid, Japan wax, carnauba wax, ceresin
Detection of adulterants
On heating with NaOH, cooling and acidifying, there should be no turbidity
Reason. Beeswax is a true wax and the saponification of the cerotic acid does not form soap unlike the adulterated samples that form water soluble salts on treatment with alkali
The wax is hydrolyzed with alcoholic alkali by heating and cooled by stirring
Reason. It should be cloudy between 59 to 61 degree Celsius and not above 61 degree Celsius
