Handleiding

This is an interesting question because

smells are almost always ephemeral, or

short-lived. To catch them and process them

is a real art which can be very exciting. By

now, scientists have established that what

we most often perceive as fragrances are

light evaporating ethereal oils.

The word ethereal comes from the Greek

word “aither” for “upper air,” and means

heavenly or delicate. In nature, ethereal

oils play an important biological role.

For example, they provide a source of

information for insects, and a protective

shield for some plants.

HOW A FRAGRANCE

IS CAPTURED

If you were to ask a chemist what perfume

is, he may answer: “Perfume is a water-

alcohol solution of perfume oils from

vegetable, animal, and/or synthetic origin.”

This is a fine definition, but how do the

perfume oils get into this water-alcohol

solution?

experiments, use only the specifically

recommended plant parts for your

HOW DOES THE FRAGRANCE

GET INTO THE BOTTLE?

Most fragrances are offered in various concentrations. The difference in

price can be enormous, depending on the differences in concentration

and alcohol content of the fragrant liquid.

TRADE NAME CONCENTRATION OF PERFUME OIL (%)

Perfume more than 22%

Eau de Parfum 15-22%

Eau de Toilette 8-15%

Cologne less than 5%

experiments. The fragrances you will

extract by yourself are not intended to be

applied to the skin. But they can be used to

apply fragrance to several materials. You

must never extract anything from sachets,

potpourris, or industrially perfumed

materials!

BREWING FRAGRANCES

IN THE KITCHEN

The oldest and simplest way of extracting

fragrant material from plants is to brew

them by boiling them in water, similar to

how tea is prepared. You have probably

already sniffed the strong aroma of fresh

peppermint tea.

> Materials from the kit: 2 measuring

cups with lids

> Additional materials: boiling water,

2 cups, 1 bag of peppermint tea, 1 bag of

chamomile tea

Experiment

1. Heat the water in a pot or kettle. Let

your parents help you with this.

2. Brew one cup each of strong

peppermint tea and chamomile tea. Let the

teas cool off some.

IS REALLY A PERFUME?
