Essential oils

Introduction

An oil is “essential” in the sense that it carries a distinctive scent, or essence, of the plant.

Essential oils do not, as a group, need to have any specific chemical properties in common, beyond conveying characteristic aromas. They are extracted from flowers, grasses, stems, seeds, leaves, roots, bark, fruit, moss and tree secretions using various means including distillation, expression, extraction, enfleurage, maceration and head space technology. They are used by the flavour and fragrance industry to create, and then manufacture, flavourings for food and beverages, and perfume compounds for cosmetics, household products and fine fragrances, amongst other items.

International business environment

  • Brazil, China, the USA, Egypt, India, Mexico, Guatemala, Morocco and Indonesia are the major producers of essential oils.
  • The EU dominates world trade but no single country here is a major producer.
  • About 65% of world production comes from developing countries.
  • There are approximately 160 essential oils traded globally.
  • The top 10 oils make up some 80% of world trade.
  • Therefore world trade in essential oils is divided into two components, referred to as the major and minor oils. Major oils are those oils traded in large quantities (but often lower prices).

South Africa: exports and imports

Imported products dominate South Africa’s sales. Most of the imports come from India, USA, eSwatini, UK and China. South Africa exports mainly to the USA, UK, Germany and France. Statistics up to 2018 are provided at www.saeopa.co.za/about-us/the-industry/industry-profile-southern-africa

Local business environment

  • South Africa has the potential to be a major supplier of certain essential oils, such as rosemary, lemon grass, lavender, lemon balm and rose geranium. The eucalyptus oil sector is some 80 years old and is largely self-sufficient and established. Others, like geranium, lavender and chamomile are relatively new.
  • The essential oil industry is driven by two main factors: commercial farmers seeking alternative high value crops to diversify risk and increase profitability; and rural communities, Government and NGO’s seeking high value crops that can be produced on a co-operative basis thereby creating jobs in economically depressed rural areas.
  • The South African essential oils industry comprises over 80 small commercial producers of which fewer than 20% are regular producers. Most oil production is Mpumalanga, KwaZulu-Natal and the Eastern Cape.
  • Since South Africa does not produce enough essential oils for its own needs the future for this sector looks promising, theoretically. Producers have found marketing their products to be difficult.
  • SAEOPA offers to present information on essential oil farming to interested farmer study groups.

Indigenous essential oils

  • Rural communities often wild harvest indigenous plants, either on their own land or that of a commercial farmer.
  • The exploitation of this indigenous plant material holds some interest for rural development, and a number of new cultivation projects are underway, with the aim of ensuring long term sustainability of these industries and enabling rural communities to create wealth from indigenous knowledge. The Western Cape, for example, is promoting the cultivation of Buchu (Agathosma sp.)
  • Other promising indigenous oils are: Artemisia afra. Leonotis leonurus, Eriocephalus sp., Lippia sp., Salvia sp., Helichrysum sp., Cymbopogon validus, Coleonema sp., Tarchonanthus camphoratus, Arthrixia sp.

 

For more information on the market trends contact the Southern African Essential Oil Producers Association (SAEOPA) (see “Associations involved” heading). The Indigenous Plant Use Forum (IPUF) is a useful place to engage with what research is happening on plants and their properties.

For the newcomer

Various essential oils have been used medicinally at different periods in history. Medical applications proposed by those who sell medicinal oils range from skin treatments to remedies for cancer, and are often based on historical use of the oils for these purposes. Such claims are now subject to regulation in most countries, and have grown correspondingly more vague, to stay within these regulations.

Interest in essential oils has revived in recent decades, with the popularity of aromatherapy, a branch of alternative medicine which claims that the specific aromas carried by essential oils have curative effects. Oils are volatilised or diluted in a carrier oil and used in massage, or burned as incense, for example.

Carrier oil, also known as base oil or vegetable oil, is used to dilute essential oils before they are applied to the skin. They are so named because they carry the essential oil onto the skin. Carrier oils do not contain a concentrated aroma, unlike essential oils, nor do they evaporate like them. There are a range of different carrier oils each with their own individual properties and suitability towards different treatments in aromatherapy. Infused oils are a combination of a carrier oil and various herbs. True carrier oils are generally cold-pressed vegetable oils such as: Sweet almond, grape seed, avocado, olive oil, sesame, evening primrose, sunflower and Jojoba oil.

  • A wide range of producers grow essential oil crops – farmers both commercial and emerging, farmers looking for alternative crops, co-operative farmers and community projects, as well as the cottage industry. The technologies for extracting and distilling the oils are reasonably easy to access and operate.
  • One of the most important aspects is marketing intelligence – before planting, find out what the buyer wants in terms of quality and quantity. This determines what to plant, how much and also what type of distillation is going to be used. This is a growing market, but it can be a risky business if all aspects of the market requirement are not taken into account.
  • Also important is weed control and management. Your essential oil product will be compromised if weeds are harvested and distilled with the crop.
  • Use essential oils to create products such as creams, bath salts, candles, potpourri and gifts. Attracting tourists is a further form of income.

National strategy and government contact

Department of Trade, Industry and Competition (the dtic) www.thedtic.gov.za

Representatives of SAEOPA have attended various trade missions sponsored by the dtic. These trade missions are largely considered to have been successful with the prospect of orders being placed. However, in the process, SAEOPA identified several issues that need to be addressed in order to secure market access: (i) The need to consolidate production in order to supply sufficient quantities with consistency. The volumes are required in order to get serious international attention. (ii) The need to have basic testing facilities (e.g. Gas Chromatograph) in order to test oils and to be able to give assurances with regards to quality and characteristics.

Department of Science and Innovation (DSI) www.dst.gov.za

The DSI is periodically involved in essential oil production. Its interest in the industry is largely channelled through initiatives like the work of the CSIR (in particularly community projects); the SA Essential Oils Business Incubator; the work of the Institute for Natural Resources (at the University of KwaZulu-Natal University); and the chemical sector incubator (Chemin) situated in Port Elizabeth.
