PEG-8 Beeswax is the result of the esterification of the free fatty acids of beeswax with polyethylene glycol.
The outcome of this process is a light colored wax with self-emulsifying properties and improved oil gelling capabilities designed to be used in all cosmetic applications.
PEG-8 Beeswax creates emulsions with a rich texture and glossy appearance.

PEG-8 Beeswax creates lotions that are bright and fluid with enhanced emolliency and spreadability.
PEG-8 Beeswax will allow the formulator to use up to 60% oil phase.
Applications include sunscreens, pomades, hair care fixatives, depilatories, ointments, creams and emulsions.
Peg-8 Beeswax is a synthetic derivative of natural beeswax and acts as an emulsifier, emollient, stabilizer, and thickener in cosmetics.
PEG-8 Beeswax stabilizes creams, lotions, and moisturizers by mixing oil and water-based ingredients well together.
This property helps PEG-8 Beeswax give a smooth, non-greasy, and luxurious texture to various products.
Further, Peg-8 Beeswax forms a light, protective layer on the skin to improve hydration and barrier support.
PEG-8 Beeswax reduces water loss and softens and conditions the skin.
In its raw form, Peg-8 Beeswax appears as a light colored wax that is dispersible in water but soluble in oil.
PEG-8 Beeswax is safe for use on the skin if strictly regulated and purified.
The wax obtained from the honeycomb of the bee.
PEG-8 Beeswax consists primarily of myricyl palmitate, cerotic acid esters and some high-carbon paraffins.
PEG-8 Beeswax is a natural wax that is formed from honeybee Apis mellifera.
PEG-8 Beeswax is a lipid that contains hydrocarbons, esters and free acids, which can be used to lower the transference of water on films.
PEG-8 Beeswax is a semi-solid non-ionic self-emulsifying wax made from esterification of the free fatty acids of beeswax (Cera Alba).
Melting point 59-70°C/138-158°F.
HLB-value 9 (gives water-in-oil emulsions).
Saponification value 77-90.
Self-emulsifying wax for making stable oil-in-water emulsions that can contain a high concentration of oils or lipophilic active ingredient.
Provides enhanced emolliency and spreadability.
Compatible with a variety of oils and wide pH range tolerance.
PEG-8 Beeswax is a polar beeswax derivative created by esterification of beeswax with polyethylene glycol.
In this way the free fatty acids of beeswax have been converted into polyethylene glycol esters.
The introduction of polyethylene glycol groups imparts hydrophilic properties to beeswax. Elimination of the free fatty acids of beeswax leads to improved oil retention and oil gelling capabilities.

White wax consists of tasteless, white or slightly yellow-colored sheets or fine granules with some translucence.
PEG-8 Beeswax's odor is similar to that of yellow wax but is less intense.
PEG-8 Beeswax absolute is obtained by alcohol extraction of beeswax.
The yield is generally less than 1%.
The yellowish-brown, viscous product has a mild, honey-like odor, and high tenacity; PEG-8 Beeswax is used almost exclusively in fine fragrances.
Crude yellow beeswax is harvested together with honey and represents a secondary secretion of the bee.
Once the honey is recovered from the honeycomb by draining the cells, the wax combs are washed with water, melted and poured into molds to harden.
PEG-8 Beeswax is refined by melting in hot water to which sulfuric acid or alkali may be added to extract impurities.
The resulting wax is referred to as yellow beeswax.
PEG-8 Beeswax contains cerolein, a mixture of fatty acids and soluble in hot alcohol and slightly soluble in cold alcohol; myricyl alcohol and myricyl palmitate, insoluble in alcohol.
PEG-8 Beeswax is produced worldwide with the same chemical composition.
The odor may vary slightly, depending on the source.
Physical properties
PEG-8 Beeswax is a yellowish to grayish-brown solid, somewhat brittle when cold, and presents a dull granular, noncrystalline fracture when broken.
PEG-8 Beeswax becomes pliable at about 35°C.
Uses
PEG-8 Beeswax is used to produce edible films (sodium caseinate, soy protein isolate etc.).
PEG-8 Beeswax can form a mixture with a variety of fatty acids and polyols to provide flexibile, elastic and stretchable films.
PEG-8 Beeswax also decreases the water vapor permeability and enhances the mechanical properties of the film.

Pharmaceutical Applications
PEG-8 Beeswax 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.
PEG-8 Beeswax is used to polish sugar-coated tablets and to adjust the melting point of suppositories.
PEG-8 Beeswax is also used as a film coating in sustained-release tablets.
PEG-8 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.
PEG-8 Beeswax coatings can also be used to affect the release of drug from ion-exchange resin beads.
Production Methods
PEG-8 Beeswax is obtained from the honeycomb of the bee (Apis mellifera Linne′ (Fam. Apidae)); Yellow.
Subsequent treatment with oxidizing agents bleaches the wax to yield white wax.
