Eucalyptus Leaf Extract Powder

Eucalyptus leaf extract starts from the leaf of Eucalyptus globulus, the blue gum tree, with the bark, fruit and the steam-distilled leaf oil excluded. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a green powder that disperses in water.

The extract is supplied at a 10:1 ratio with no marker percentage and is milled to 80 mesh. It carries the non-volatile leaf fraction, and the essential oil sold under the same species name is a separate material that is not part of this extract.

Eucalyptus globulus Identity & Plant Part

The botanical entity is Eucalyptus globulus Labill., Tasmanian blue gum, a tall evergreen of the Myrtaceae. The part used is the leaf. Bark, flower buds, woody fruit and the distilled oil are not part of this ingredient. Young blue gum leaves are rounded, waxy and blue-gray, while adult leaves are long, curved and glossy green, and both appear in leaf material of this species.

The identity risk is the oil. Most eucalyptus products on the market are essential oil rich in 1,8-cineole, and cosmetic extracts follow a different process. A dried water extract keeps polyphenols instead, namely ellagitannins, flavonoids, phenolic acids and acylphloroglucinol-terpene compounds, named only as constituent families.

Eucalyptus globulus is grown widely outside Australia, so leaf lots differ in origin, and the botanical name on the certificate is the main identity check.

What 10:1 Means for Eucalyptus

A 10:1 water extract of eucalyptus leaf is a very different material from the oil that most buyers associate with the plant. The ratio measures concentration against the Eucalyptus globulus leaf and does not describe cineole, tannin or flavonoid content. Cineole leaves with steam during drying, so the powder is defined by its water-soluble polyphenols. A stated tannin or flavonoid figure has to come from a marker-based product. Leaf powder and standardized grades of this tree are not listed beside it.

Application Areas

Leaf Extract Capsules

Eucalyptus extract suits two-piece capsules as a dispersible green powder. With the oil gone, the powder is drier and less sticky than the milled leaf. Opaque capsule shells protect the green color from light, and fill weights are confirmed early in a run.

Tannin-Aware Tablet Blends

The extract goes into tablets with microcrystalline cellulose and a disintegrant, and ellagitannins can discolor in contact with iron. Stainless tooling is used, and a film coat hides the green-brown color and the astringent taste. Dry granulation limits sticking.

Green Tea-Style Instant Mixes

Instant tea-style powders use the extract with lemon, mint and honey flavors. The cup is hazy green-brown and moderately astringent. A carrier in the dry blend keeps dose even across sachets, and barrier film protects the green shade.

Powder Stick Drinks

Sticks combine the extract with fruit flavors and sweetener, which offset astringency. It disperses to a hazy tan-green liquid. Mixes are protected from light and heat, since polyphenols darken during storage. Filling in a dry room keeps the green powder free-flowing inside the stick.

Gummy Base Blends

Gummies carry the extract in lime, apple and pear flavors that suit its green tint. Add it late in the cooked base, and test finished color and astringency once the gel has set, because tannins tighten the mouthfeel at room temperature.

Formulation Notes

Eucalyptus leaf extract is a green powder with a faint, resinous and slightly woody aroma and an astringent, bitter taste. In water it disperses to a hazy green-brown liquid, and fine particles settle on standing. The sharp, medicinal smell of the oil is largely absent after water extraction and drying.

Ellagitannins and flavonoids darken with iron, light and heat, so the powder is stored in a closed liner away from sunlight and handled with stainless or plastic tools. Weigh it in a dry room, since leaf extracts attract humidity. Check shade against a retained sample when a new lot arrives, because the green tone shifts to brown with age.

A Eucalyptus globulus extract lot that arrives browner than the previous one is compared with a retained sample before blending.
