物理的性質
It is a yellowish to grayish-brown solid, somewhat brittle when cold, and presents a dull granular, noncrystalline fracture when broken. It becomes pliable at about 35°C.
-
天然物の起源
Wax from the honeycomb of the bee, Apis mellifera L.
-
使用
Beeswax is used to produce edible films (sodium caseinate, soy protein isolate etc.). It can form a mixture with a variety of fatty acids and polyols to provide flexibile, elastic and stretchable films. It also decreases the water vapor permeability and enhances the mechanical properties of the film.
-
製造方法
By alcoholic extraction of the raw wax(Fenarolfs Handbook of Flavor Ingredients,
1975).
-
調製方法
Yellow wax (beeswax) is obtained from the honeycomb of the bee
(Apis mellifera Linne′ (Fam. Apidae)); see Wax, Yellow. Subsequent
treatment with oxidizing agents bleaches the wax to yield white
wax.
-
一般的な説明
Beeswax is a natural wax that is formed from honeybee Apis mellifera. It is a lipid that contains hydrocarbons, esters and free acids, which can be used to lower the transference of water on films.
-
応用例（製薬）
White wax is a chemically bleached form of yellow wax and is used
in similar applications: for example, to increase the consistency of
creams and ointments, and to stabilize water-in-oil emulsions.
White wax is used to polish sugar-coated tablets and to adjust the
melting point of suppositories.
White wax is also used as a film coating in sustained-release
tablets. White beeswax microspheres may be used in oral dosage
forms to retard the absorption of an active ingredient from the
stomach, allowing the majority of absorption to occur in the
intestinal tract.Wax coatings can also be used to affect the release of
drug from ion-exchange resin beads.
-
安全性プロファイル
A mdd allergen.
Combustible when heated.
-
安全性
White wax is used in both topical and oral formulations, and is
generally regarded as an essentially nontoxic and nonirritant
material. However, although rare, hypersensitivity reactions to
beeswax (attributed to contaminants in the wax) have been
reported.
-
貯蔵
When the wax is heated above 150℃, esterification occurs with a
consequent lowering of acid value and elevation of melting point.
White wax is stable when stored in a well-closed container,
protected from light.
-
不和合性
Incompatible with oxidizing agents.
-
