Q&A

All our products are stored in a cold room, at a constant temperature and a maximum of 15 °C (59°F). Essential oils, vegetable oils and hydrosols are sensitive to heat that could strongly damage them with a microbial infection.

Our advice:

At the reception of your order, we recommend to store the products immediately in a cold room or even in your refrigerator, or in a cool place away from light.

In this way, you increase the lifespan of your products and will keep their therapeutics qualities. After being opened, products absolutely need to be refrigerated.

Essential oils:

– Essential oils distilled by steam have a 5 years lifespan

– Essential oils (essences) extracted by cold pressure, as lemon, orange, … have a 3 years lifespan.

After opening:Essential oils absolutely need to be preserved in their original packaging (amber glass flask) away from light, air and in a cold place.

Please note that citrus essential oils are more sensitive to oxidation.

Vegetable oils:

– Vegetable oils have a 3 years lifespan

After opening: Vegetable oils can be preserved until the Use by date (this date is indicated on the bottom of the label), preferably at a temperature of 15°C (59°F) in its original packaging (blue plastic bottle), away from light.

Maceration oils:

– Maceration oils have a 4 years lifespan.

After opening:maceration oils can be preserved until the Use by date (this date is indicated on the bottom of the label), preferably at a temperature of 15°C (59°F) in its original packaging (blue plastic bottle), away from light.

Hydrolats:

– Hydrosols have a 6 months lifespan, unless they are preserved in a refrigerated place.

For the most sensitive ones, like Corn Flower, Hamamelis, Melissa, St John’s Wort, Linden, Centifolia Rose, Eucalyptus Globulus, please check at reception and opening that your hydrolat does not show any floating substance, showing a microbial infection.

After opening: we recommend the use of the hydrosols within 2 months. Please note that our hydrosols include no preservative. So as to optimize this lifespan, please scrupulously follow our storage advices, but also make sure not to leave a bottle close to a constant light and to close the bottle after use.

We also recommend to carefully wash your hands before each use.

A bottle with a maximum capacity of 5 gr allows the filling of bottles of 2 gr and 5 gr. The capacity is written on your label.

Important remark: 2 products of 5 gr each do not systematically have the same level of filling (as the densities can vary).

You can find the density of each lot on the page of the concerned product on our website, in the sections:

Analysis: for hydrosols, vegetable oils and macerated oil

Chromatography: for essential oils and absolutes

Please note that density is different for each lot.

For its use, some steps have to be observed:

1. Open the essential oil bottle

2. Two possible cases:

You bought a bottle of essential oil Florihana and you want to avoid any mixing. In this case, please remove the drip (transparent plastic drip inserted in the bottle).

You want to mix oils. In this case, transfer your oils into the empty bottle.

3. Screw the black adapter (large black cork) on your bottle.

4. Place the whole set inside the diffuser (watch out for the direction)

5. Close the top of the diffuser

6. Plug in your appliance with the adapter. The connection is located under the appliance (the cable is supplied in the box).

Connect the USB cable to the diffuser. The other part of the cable has to be connected to the adapter: 100/240V supplied, or to the USB port of your computer.

Be careful, the adapter is only usable with French sockets.

7. Switch on the diffuser (large button in the center)

8. Adjust the appliance according to your needs:

Timer or diffusion period: press the timer button to switch it on. Press a second time for a diffusion period of 30 minutes. Press a third time for a diffusion period of 1 hour, and so on …

The button “on int” allows the selection of the diffusion period

The button “off int” allows the selection of a period between two diffusions.

By pressing the central button (the one of the switching on or symbol on/off) you can, following some pressures, select the power of diffusion.

9. Switch off the appliance with a pressure on the central button.

This diffuser can exclusively be used for the diffusion of essential oils, without adding any water nor alcohol.

It is highly recommended not to exceed 1h30 of diffusion per day.

The diffusion area is 120-150 m2

This diffuser has a one-year guarantee and is manufactured in China.

• Some essential oils  (and also absolutes) can turn solid due to a room temperature below 15°C (59°F). In order to unfreeze them all you need to do is to warm them between your hands in order to get them liquid and ready to use. If this is not effective, leave the product away from light at ambient temperature.
  
  Please note that the rose essential oils will turn solid at a temperature below 20°C (68°F).

There is a child security on the caps of the bottle you need to put pressure on top of the cap and then turn the cap counterclockwise as it is shown on the icon of the cap.

If it still does not work please put the bottle on a level surface and push down using the entire arm/body weight, and twist counterclockwise it should release the lead.

If you have purchased Florihana products before you will know that all of our essential oils come with a child security cap. Very occasionally, we find that the caps can be difficult to open.

Usually it is possible to open the bottle by following these simple steps:

– Firstly, if the cap is clicking rather than engaging the mechanism and turning then don’t force it so that it clicks round and round. This can damage the mechanism and make it more difficult to open

– Wear rubber gloves, or have a tea towel or cloth to hand – Boil your kettle and when it has boiled, put enough water in the bottom of a mug to cover the essential oil cap

– Turn the bottle upside down and put it in the mug. Leave for a couple of minutes to warm the cap

– Wearing rubber gloves (or using your towel or cloth), firmly grip the cap, press down and turn counterclockwise.

This method should release the essential oil cap.

Density: a body density is the ratio of its volumetric mass and of a body volumetric mass taken as reference.

For liquids, the reference body is pure water at 4°C (volumetric mass = 1kg/m3).

Density is a size with no dimension, and its value converts with no unit of measurement.

The volumetric mass for a liquid is: R= m / v

“m” being the mass of a homogeneous substance, occupying a volume “v”.

By definition, density is the ratio between two volumetric masses (volumetric mass of water). A body density is consequently given by the relation.

Density (d) converts as follows: d = m / v

In order to know the mass of a product according to its density, its density must be known.

m = d x v

In our bottles, we fix the mass of our products (2g, 5g, 15g and 50g for the essential oils).

Thus, there is a volume difference according to the density.

Example:

For the essential oil Coriander, the density is 0.862 if its weight is 5g, knowing that m = d x v -> v = m / d -> v = 5 / 0.862 = 5.80 ml

For the essential oil Clove, the density is 1.042 if its weight is 5g, knowing that m = d x v -> v = m / d ->v = 5 / 1.042 = 4.80 ml

The filling volume will thus be different accord the product and its density.
