Perfume Making Workshop @ Science Centre

This is the end product of Christopher's and he is very happy about it.

Filling the solvent into the perfume.

Dropping a few droplets of the different scent of oil or perfumes.

Shakti was smelling the ester.

The substance used to make the ester that Shakti smells.

Pour 200ml of distilled water into the water.

Crushing the Jasmine flowers.

The end-of-yearexaminations are over, and SST has planned a range of activities for us. One of them was to learn about the making of Perfume at Science Centre. Perfume making are separated into three segments with four
experiments.

The first segment is extraction of the smell from two natural raw materials.The first experiment is about solvent extraction of the Jasmine flowers.

Then pour the crushed flowers into the water and stir in one direction for three minutes.Here is how we extract it.First crush the Jasmine flowers in a pack.

Secondly, prepare a beaker filled with 200ml of distilled water.

Finally carry out the filtration process and collect the Jasmine water.

To smell it shake it throughly as it is non - soluble and so as to redissolve the Jasmine water.

The next experiment is to find out the lime scent. First, scrape the lime skin along the grater.We took turns to grate it and while grating, we smelt the scent of the lime. The instructor told us that the grated pieces are actually where the citric oil is.

At the second segment, we learn about esters, creating esters and writing a word equation. Ester are scented organic compounds. To make a ester,the instructor ask us to pass her our beaker which she filled with Salicylic Acid Crystals, Methanol and Concentrated Sulphuric Acid which act as a catalyst.

Lastly the the third segment which all of the students love is making their own perfume. Before that , the instructor gave us a crash course on the three part of the perfume. The top note which is most refreshing, most volatile and evaporate the fastest. The next is the heart note, which last the first few minutes and somewhat the neutral type. Finally is the base note, this is the last to evaporate and normally after one day the smell will change.

After that, we were given a glass vile to store our perfumes.Then the instructor said to forget about all those and ask us to mix our favorite smells together and the result may be the same as the smells that we choose. Most pioneers went around tables mixing different smells and the result were astonishing as some came out good well some were very smelly.
