Eucalyptus Smithii Essential Oil, 100 ml

Essential oil from Eucalyptus smithii is added to cosmetics for its fragrance. It smells fresh and camphoraceous, with the clean note most people associate with eucalyptus. It is obtained by steam distillation of the leaves of the Eucalyptus smithii tree and is sold pure, undiluted. According to the manufacturer, it gives the skin a cooling and refreshing feeling, so it suits shower and bath products, massage oils, hair care products and diffusers.

In a formulation, it serves as a fragrance ingredient with aromatherapy uses. It is handled like other essential oils: it is added at the end to a cooled base, and the highest dose in the finished product is set by the IFRA limit for the given category. There is no single universal value for all products.

Fragrance and appearance

The fragrance is typically eucalyptus: fresh and camphoraceous. In its documentation, the manufacturer classes it among fresh fragrances with a citrus character. According to its data, the scent profile is shaped mainly by eucalyptol and alpha-pinene. The oil is a colourless to pale yellow, thin liquid.

What it brings to a formulation

• Fresh fragrance – a scent note for shower and bath products, massage oils and aromatherapy, on its own or as part of a composition.
• Cooling feeling on the skin – according to the manufacturer, the oil gives a refreshing, cooling sensation that can be used in body oils, balms and after-sun products.
• Refreshing the scalp – the manufacturer recommends it for shampoos, conditioners, hair oils and scalp products, where it adds fragrance and a feeling of freshness.
• Soothing irritated skin – the manufacturer states a soothing effect on irritated and reddened skin and support for a clear-looking complexion. The result in the finished product depends on the dose and the whole recipe.

Use in a formulation

The oil is soluble in oils and in alcohol and does not dissolve in water. In anhydrous products, that is massage oils, body oils, balms and body butters, it is mixed directly into the oil phase. For balms and butters that are melted during production, it is added only after the mass has partly cooled.

In emulsions, it is added at the end, into the cooled emulsion while stirring continuously. The recommended processing temperature is below 40 °C. The oil is a blend of volatile components, and at a higher temperature some of them are lost. Water-based products such as facial toners or body mists need a solubiliser, otherwise the oil separates from the water. It is compatible with alcohol: in hydroalcoholic sprays and fragrances it dissolves directly in the alcohol component.

Suitable for products such as

• Shower gels and bath products – rinse-off products in which the fragrance stands out.
• Shampoos, conditioners and hair oils – hair care and scalp products.
• Massage and body oils, balms – anhydrous products in which the oil dissolves without any auxiliary ingredients.
• Body lotions and creams – emulsions to which it is added after cooling.
• Facial toners and body mists – with a solubiliser or in an alcohol base.
• Diffusers and aromatherapy – on its own or blended with other essential oils.
