The use of eucalyptus oils in consumer products

Insect repellents

As noted in the introduction, Eucalyptus citriodora oil has been used as a ‘natural’ insect repellent. Depending on the product formulation it is used in, Lemon Eucalyptus (known as Quwenling in China) is up to four or five times more effective and longer-lasting than citronella oil (from Cymbopogon nardus), one of the best known natural insect repellents. p-Menthane-3,8-diol is the main active component of Quwenling and this can be isolated and used as a highly effective insect repellent. Eucalyptus citriodora oil contains up to 80–90 per cent citronellal, along with geraniol, both of which are known to have insect repellent activity but tend to dilute the much higher activity of the p-menthane-3,8-diol.

The Mosi-guard Natural insect repellent spray produced by MASTA in the UK contains ‘Extract of Lemon Eucalyptus’ and claims on the label:

Approved and recommended by the London School of Hygiene and Tropical Medicine. Field trials have shown effective protection for 6 h after a single application in mosquito infected areas. Also protects against many other biting insects. Mosi-guard Natural is made from a natural and renewable resource. It is kind to your skin and has no adverse effects on fabrics and surfaces. Apply Mosi-guard Natural to exposed areas as often as required.

Eucalyptus citriodora was traditionally used for perfuming the linen cupboard by putting the dried leaves in a small cloth sachet. During the last century, its use as an insect repellent was recognised, especially against silverfish and cockroaches.

The use of eucalyptus oil as a natural flea repellent, sprayed around the home three times a week as a dispersion in water, has also been advocated. Pets and their bedding can be sprayed with the same solution. An equine shampoo, containing eucalyptus oil as a natural insect repellent, is also available for sale on the Internet.

The insect repellency properties of eucalyptus have also been reportedly used in mosquito mats in India.

Medicinal uses

Today, the number and diversity of medicinal products containing eucalyptus oil which are marketed is very large indeed. This is illustrated in Table Examples of pharmaceutical products containing eucalyptus oil which are marketed in Australia, Europe, Thailand and the United States which lists some, but by no means all, of the products which are available in Australia, Europe, Thailand and the United States. Note that there are many more products which contain eucalyptol (cineole) and although these are derived from eucalyptus oil they are not included in Examples of pharmaceutical products containing eucalyptus oil which are marketed in Australia, Europe, Thailand and the United States.

  • Source: RPS (1996), Ody (1996) and retail outlets in the UK and Thailand.
  • Products containing ingredients listed as eucalyptol/cineole are not included.
  • The list is intended to be illustrative rather than exhaustive. Some products may no longer be marketed; or they may be used for the treatment of conditions different, or additional, to those described; or they may no longer be labeled as containing explicitly ‘eucalyptus oil’. Company names may also have changed.

Eucalyptus is widely used for the treatment of asthma, bronchitis, catarrh, colds, influenza and sinusitis. Vaporisers and aromatherapy oil burners can be used in the home to distribute the essential oil odour around the room, helping to purify the air and aid breathing. There are also numerous inhalation/chest rub products on the market, one of the most well-known being Vicks VapoRub (Proctor & Gamble), which has been marketed for over eighty years. The oils used in this, and similar products, which have demonstrated a clinically significant contribution to the overall nasal decongestant effects of the product, are Eucalyptus, Camphor and Peppermint (menthol). Vicks VapoRub ointment contains as active ingredients: Camphor B.P 5.46% w/w, Menthol B.P. 2.82% w/w, Turpentine oil B.P. 4.71% w/w and Eucalyptus oil B.P. 1.35% w/w in a petrolatum base. Non-medicinal ingredients are typically Cedar leaf, Nutmeg and Thymol.

A typical formula for a decongestant oil is:

Cedar leaf2

This is then mixed with pure petroleum jelly for use as a chest rub or encapsulated for use with hot water as a decongestant.

Hall’s Mentho-Lyptus cough suppressants, Listerine mouthwash, Olbas oil and various nasal inhalers are further examples of products utilising the refreshing and expectorant properties of Eucalyptus. A recent eucalyptus product, Eucalyptamint, has been promoted in the United States as a treatment for muscle soreness. Researchers at the University of California are reported to have tested the ointment and discovered that it increases the blood flow to muscle tissue ().

Tigerbalm is one of the most popular liniments, traditionally used in Asia but now widely available in the West. A Chinese merchant is said to have composed the first Tigerbalm, based on the ointment that tradition says was used by Genghis Khan’s Mongolian horsemen and which was very effective against saddle and backache. A typical formula is:

Vegetable oil10

This is then mixed with pure petroleum jelly (adding the above oil at about 15% w/w). A small spot is applied to the forehead to alleviate headaches, or it can be rubbed on aching muscles or insect bites. However, in Tigerbalm products currently marketed in the UK eucalyptus oil appears to have been replaced by cajeput oil (from Melaleuca cajeputi) which also contains a high level of cineole and has similar warming, expectorant and analgesic properties.

Other applications of eucalyptus oil include its use in a footbath for sore feet (one teaspoon in a bowl of hot water) and addition to the water used in saunas or steam rooms to invigorate and relieve congestion. It can also be used to prevent blistering caused by burns or over-exposure to the sun, to soothe itching caused by insect bites or rashes and to aid healing of sores, cuts and abrasions.

Aromatherapy uses

The reported medicinal and aromatherapeutic properties of Eucalyptus are legendary. Amongst the properties attributed to Eucalyptus globulus and other cineole-rich oils by various aromatherapy texts are the following:

Antineuralgic (relieves or reduces nerve pain)
Antiphlogistic (checks or counteracts inflammation)
Antispasmodic (prevents and eases spasms or convulsions)
Balsamic (soothing, having qualities of a balsam)
Cicatrisant (promotes healing by formation of scar tissue)
Depurative (cleanses the blood)
Diuretic (aids production of urine)
Febrifuge (reduces fever)
Hypoglycemiant (reduces blood sugar levels)
Prophylactic (prevents disease or infection)
Rubefacient (causes redness of the skin)
Vermifuge (expels intestinal worms)
Vulnerary (helps heal wounds and sores by external application)

Aromatherapy texts also recommend Eucalyptus in cases of boils, pimples, dandruff, athlete’s foot, measles, nervous exhaustion or fatigue and various other complaints. In addition to its physical benefits, Eucalyptus is claimed to act on the emotional centre of the brain. With the properties of centring, balancing and stimulation, it can be used for treating exhaustion, congestive headaches, an inability to concentrate, mood swings and temper tantrums.

In aromatherapy, Eucalyptus is said to blend well with Angelica, Benzoin, Black pepper, Cedar wood, Coriander, Geranium, Juniper, Lavender, Lemon, Lemongrass, Marjoram, Melissa, Peppermint, Pine, Rosemary, Sandalwood, Spearmint, Tea tree, Thyme and Wintergreen. It is said to combine well with Lemon for mental clarity and with Myrtle for building up the immune system. The heating effect of Eucalyptus can often be balanced by mixing it with a ‘cooling’ oil such as Lavender or Peppermint (to reduce fever).

Typical formulations for personal care products

Eucalyptus oils can easily be incorporated into detergent or soap-based products or those based on alcohol or vegetable/mineral oils. However, their strong odour may conflict with other fragrances which are used in the products. Furthermore, in common with other essential oils, eucalyptus is not water-soluble and so cannot easily be incorporated in purely aqueous products without adding a solubiliser (usually a type of non-ionic detergent).

One way of circumventing any odour and water solubility problems is to use one of the many eucalyptus herbal extracts, widely available around the world, where solvents such as propylene/butylene glycol, glycerol or ethanol are used to extract the fresh plant material. In these cases, and depending on the extraction methods used, the components of the extract will differ significantly from those of the essential oils. However, under the sixth Amendment to the EU Cosmetics Directive the INCI (International Nomenclature for Cosmetic Ingredients) name used on European product packaging is the same for both oil and extract, namely the Linnaean botanical name of the plant species used, for example, Eucalyptus globulus. However, the solvent used, such as propylene glycol, will also appear somewhere in the ingredient listing. In the USA, the CTFA3 INCI name ‘Eucalyptus Globulus Extract’ or ‘Eucalyptus Globulus Oil’ must be used until such time as the two sets of nomenclature are fully harmonised.

Formulations and methods of preparation for some typical personal care products containing Eucalyptus are given below, where European INCI names are used throughout.

Oral health care

The therapeutic properties of eucalyptus oils and extracts have meant that their use in oral health care products such as toothpastes, mouthwashes and chewing gums is becoming more common. Euthymol by Warner Lambert, a traditional style toothpaste, is based on the renowned natural antibacterial properties of Eucalyptus and thymol. Eucalyptus is believed to kill bacteria that cause halitosis and is said to be particularly effective against breath problems caused by strong-smelling food and drink. Microbiological testing by Quest has demonstrated that Eucalyptus globulus oil (with an 80—85 per cent 1,8-cineole content) has moderate antimicrobial activity against both Gram-positive and Gram-negative bacteria.

The Eucalyptus may thus be present as an active agent, for example, as a decongestant (along with menthol) in the Wrigley’s Airwaves ‘vapour release’ chewing gum, or as part of a more complex flavour compound. Eucalyptus is not common as a predominant flavour ingredient in oral care products as it has a medicated note that is not liked by some people, particularly in North America. Clark () cites a 1992 Wall Street Journal article which reported that the major brands of mouthwash which contain eucalyptol were all losing market share. However, Eucalyptus is used to give lift and some freshness to oral care flavours.

One interesting application of Eucalyptus is in a mouthwash to combat or reduce snoring. A product called ‘Good Night Stop Snore’ is available by mail order in the UK. This is claimed to be an effective natural remedy for snoring if used every night. The mouthwash contains a blend of natural essential oils including Peppermint, Thyme, Fennel and Eucalyptus. These are said to have the combined effect of clearing bronchial congestion, whilst toning and increasing blood supply to the soft palate.

Another interesting oral care use is in an ‘aromatherapeutic’ chewing gum, designed to impart a stress-free mind as well as fresh breath. Peace of Mind Gumballs are marketed by Origins (Estée Lauder) in the USA as part of their Sensory Therapy line. They contain a blend of relaxing essential oils, including Peppermint, Basil and Eucalyptus. The latter is added for its ‘tranquil effect’.

Research by Osawa and Yasuda at the Lotte Central Laboratory in Japan found that extracts of the dried leaves of Eucalyptus globulus showed appreciable antibacterial activity against the bacteria that cause dental caries and periodontal disorders (). The researchers identified eight compounds that exhibited antibacterial behaviour, three of which (macrocarpals) had never been isolated before (). These macrocarpals have greater antibacterial activity than thymol, commonly used as an oral antibacterial agent. The extracts also act as inhibitors of glucosyltransferases, used by cariogenic bacteria such as Streptococcus mutans to synthesise insoluble glucans. These adhere to the tooth surface, forming dental plaque and leading to acid attack of the enamel. Further work was planned to involve in vivo testing as a possible new natural cariostatic drug for the maintenance of oral health.

In a draft review by the Food and Drug Administration Dental Plaque Subcommittee in the USA, a fixed combination of menthol, Eucalyptus, thymol and methyl salicylate is classified as a Category I, safe and effective oral care ingredient. The final report was due to have been published during 1999.

Cleaning uses

Eucalyptus oil can be used in a wide variety of ways as a cleaning agent. It is perhaps best known in Australia as a wool wash () but other applications in the home include use in carpet shampoos, floor and general hard surface cleaning, spot and stain removal from clothes and furniture, as a solvent for the removal of chewing gum and for general air freshening. Elsewhere, it can be used as a leather or vinyl cleaner and for the removal of tar marks from motor vehicle paintwork, residues from stickers, labels or sticky tape, and grease or paint from the hands (when it will also eliminate obnoxious odours). These properties utilise the ability of cineole and other monoterpenes to act as a solvent for other oily or greasy molecules.

A general purpose cleaner which contains Eucalyptus is included in Table Examples of personal care and other products which contain eucalyptus oil.
