We are producers of plant raw materials and manufacturers of natural extracts. Concentrating the best of plants in a bottle is a highly technical process. We offer different types of extracts: Essential oils, Absolutes, Vegetable oils, Hydrolates, Macerates, and a few other technical and specific products. Below you can find out more about each type of extract and the different extraction techniques. A high quality natural extract starts with a specific soil, a climate, and quality plants that flourish in their environment, grown and harvested with care, at the right time. Fresh flowers must be distilled on site, as close to the field as possible, to get the best out of them. Various controls throughout the process and many years of experience mean that we can optimise the quality of the extract, its organoleptic and aromatic properties, smell, colour, concentration of active molecules, and avoid undesirable alterations and residues. And to achieve this in a sustainable way, we also make sure that we respect nature, save resources, do not deplete or pollute the soil, and respect people by enabling agricultural cooperatives and local economies to survive and develop. As part of this approach, more and more of our products are certified Organic and Fair For Life.
Absolutes are generally diluted on a carrier, usually an alcohol, to make them easier to handle and incorporate into preparations and perfumes: Ethanol, TEC, MPG.
It is also possible to obtain absolutes from an enfleurage ointment, CO2 extract or balsam.
These are highly technical products, and the vast majority of our absolutes are manufactured at our main production site in Le Sen, in the Landes region of France.
In terms of yield, for example, for jasmine, you need around 750kg of flowers to obtain 1kg of absolute, which enables you to make around 3000L of perfume. To obtain 1kg of Labdanum absolute (cistus gum extract) you need 50kg of twigs.
1 Triethyl citrate (TriEthyl Citrate TEC) is a natural product resulting from the esterification of citric acid with ethanol. It is naturally present in wine and is easily metabolised by the human body. In cosmetics, this ingredient is used in deodorants, as an alternative to aluminium salts, for its ability to combat body odour and its antibacterial properties. TEC is authorised for organic use.
2 MonoPropylene Glycol. This is a synthetic product which we avoid using wherever possible at Landema, preferring the natural TEC alternative.
List of our absolutes :

-Essential oils obtained by steam distillation: water is boiled and the steam passes through the plants, carrying the aromatic compounds with it. The whole is condensed, cooled and then the essential oil separates naturally by decantation, as its density is different to that of water. The resulting water, which still contains certain water-soluble aromatic molecules, is called floral water or hydrolat. The cycles, temperatures and heating times are optimised for each type of plant material to get the best out of it.
-Hydro-distillation is the oldest technique, dating back to Antiquity. It uses the same principle, but the plants are immersed directly in boiling water.
-Essences obtained by mechanical means for citrus fruits (cold expression and centrifugation or scraping of the zests).
-Dry distillation (vacuum distillation) this technique is used to distil heavy molecules that are not volatile enough at ambient temperature and pressure. This is the case for Peruvian wood resin essential oil, for example. Most of our essential oils are harvested and distilled directly on our farms. In other cases, either we work with local partners to buy the raw materials and distil them at our main production site in France - this is the case for the most advanced extraction techniques (continuous steam distillation, dry or vacuum distillation, fractionation), or we buy the essential oils from a trusted partner who distils them as close as possible to the fields, usually using a traditional method. In all cases, quality control and final packaging are carried out in France by our teams, who guarantee product quality and traceability and draw up full documentation.
Yields vary greatly from one plant to another, from cultivation to distillation, and this goes a long way towards explaining the price differences between essential oils.
For example, one hectare of fine lavender can yield 15 to 40kg of essential oil, and 80 to 100kg for lavandin. It takes around 650 litres of dried green matter (stems and flowers), or 150kg, to obtain 1kg of lavender essential oil.
For cloves, 7kg are enough to obtain 1kg of essential oil. Cistus requires 1600kg of twigs and leaves.
For rose, 3 to 4 tons of flowers are needed to obtain 1kg of essential oil. Knowing that at harvest time, one person picks an average of 15,000 flowers a day, or 3 bags of 15kg, to obtain 15 grams of essential oil, it's easy to see why Damask Rose essential oil is one of the most precious!

Vegetable oils are most often co-products of the food industry and require specific extraction techniques, and we work with rigorously selected producers and specialist partners. We also pay close attention to the method of cultivation and the social and environmental impact of the entire chain, striving to promote and develop responsible and sustainable practices. All products are analysed in our laboratory, and quality control and final packaging are carried out on our premises in France, at Le Sen in the Landes region.
In cosmetics and aromatherapy, vegetable oils can be used as functional ingredients, as carriers for other ingredients such as active cosmetic ingredients or essential oils, or for their intrinsic properties (moisturising, nourishing, soothing, healing, antioxidant, etc.).
For food use, virgin and organic vegetable oils are often preferred, and generally sought after for their essential fatty acid content (omega-3, omega-6).
List of our vegetable oils :
- Apricot kernel (Prunus armeniaca)
- Argan deodorized (Argania spinosa)
- Black cumin (Nigella sativa L.)
- Coconut (Cocos nucifera)

- Hemp (Cannabis sativa)
- Jojoba (Simmondsia chinensis)
- Sweet almond (Prunus dulcis).
There are several types of macerates:
Glycerine macerate: product obtained by macerating a fresh or dry plant in alcohol and vegetable glycerine.
Hydroalcoholic glycerol macerate: product obtained by macerating a fresh or dry plant in a mixture of water, alcohol and vegetable glycerine. In gemmotherapy, the macerated parts are plant buds and young shoots.
Oily macerate: product obtained by macerating a fresh or dry plant in a vegetable oil.
Hydroalcoholic macerate: product obtained by macerating a plant in alcohol and water. The pharmacopoeia recommends a method of manufacturing mother tinctures to be followed for use in medicines and homeopathy.
Most of our macerates are made at our production site in Die, Drôme Provençale.

Essential oils are natural aromatic substances extracted from plants. They are often used in aromatherapy for their health and wellness benefits. Essential oils can be extracted from different parts of plants, such as leaves, flowers, barks, roots or seeds. The use of essential oils dates back to ancient times, where they were used for their medicinal properties and to perfume cosmetics and skincare products.
