CARRIER OILS

Carrier oils are rich in vitamins and minerals and are of incredible benefit to the skin. Each oil offers different properties and the choice depends on the therapeutic benefit being sought. They can be used for moisturising, protecting and soothing the skin, wound healing and maintaining skin elasticity. Carrier oils keep skin and hair soft, lustrous and smooth. They are also used in massage as carriers of essential oils, facilitating their safe dilution and absorption into the skin. They can also be used as a base for natural soaps, creams and lotions.
Organic Cold  Pressed Oils
Cold pressed vegetable oils are the best and generally superior quality oils. The term cold pressed states that the oil is produced by pressing without supplying extra heat. Thy are neither refined with chemicals or solvents, nor deodorized with steam. The term "cold-pressed" is not an indication of the temperature used in the process, for example, seed oils are extracted at an average temperature of 37°C. The freshly pressed oils are collected in stainless steel tanks and then pumped through filters, which extract the remaining seed sediment. The oil is then transferred to chilled oil stores and protected from natural light. Cold pressed oils have a limited shelf life and should not be exposed to high temperature.

To achieve the highest quality virgin cold pressed oil, vegetable matter should only be pressed once, so the highest level of the naturally occurring essential fatty acids is retained. For nutritional oils such as flax seed oil, this process produces a premium oil, high in Omega 3 with a smooth rich taste. For personal care oils, it produces high quality oils, rich in natural antioxidants, including Vitamin E and essential fatty acids.

* denotes that the oil is " produced to ecological standards and free from agro-chemicals"

Refined Oils

A refined oil is produced by pressing plant material under high temperature or by solvent extraction. Water, acid, brine, activated carbon or bleaching clay may be used in the refining process to remove unwanted substances, such as cloudy matter, colouring, odours, flavouring substances or solvent residues. The benefit of a refined oil is that the process removes odour and colour, producing a crystal clear product with an extended shelf life of up to 24 months, compared to natural oils which may only have up to 12 months shelf life. The process does not affect the fatty acid profile of the oil. However, the final product will lose sensitive substances like betacarotene and vitamin E, and secondary plant compounds like carotinoides.

Deodorisation:  If an oil has a strong, unwanted odour, flavour or colour, it is possible to deodorise it, by treating it with steam up to 240 degrees centigrade.  This does not involve chemicals, so is permissible with  organic oils.  Lotions, body oils and balms are often made with deodorised oils, as a strong, unwanted odour may be problematic.  The process does not affect the quality of the oil, or the fatty acid profile, but will enhance the shelf life. 

Natural Oils

Natural oils are produced from conventionally grown seeds, kernels and fruits. The oil may be produced by cold pressing and filtering, or by CO2 extraction

Wheatgerm, Crude (unrefined) Triticum vulgare 3.90 5.85 11.40 19.80 35.25

CO2 extraction:  When a certain amount of pressure is applied to carbon dioxide, it turns into a liquid which is very inert, safe and can be used as a "liquid solvent" in the production of certain carrier oils.

Macerated Oils
Macerated oils are made by placing herbs and plants selected for their therapeutic properties, into cold pressed Sunflower, Sweet Almond or Olive Oil and then leaving them in the sun for several weeks. The sun helps to infuse the active plant ingredients, essential oils and other plant material such as the colour, to gently transfer their healing qualities to the oil.
