The Biology and Chemistry Behind the Scented Bathroom Soft Scrub

The Biology and Chemistry Behind the Scented Bathroom Soft Scrub

Hey guys! Welcome to House Cleaning Toronto video blog. Based on popular request, we’ve made a video to show you how to make the perfect Scented Bathroom Soft Scrub.

We don’t just make dull-smelling natural products; we use perfumery and aromatherapy to make uplifting and energizing cleaning products. We’ll teach you the chemical and biological basis of our choices and even make the Bathroom Soft Scrub in front of you.

Much like how musical notes make up a song, and different colors blend together to make a painting, fragrance notes are necessary to make a perfume.

Overall, there are three note scales used to make a perfect fragrance. Top notes, also called opening notes or head notes have the lightest molecular structure. What does that even mean practically? It means the top note scent evaporates the fastest. You can smell it as soon as you apply the fragrance. It represents the first impression. The top note should lure you in and smoothly transition into the heart of the fragrance. The top note we will use is peppermint.

Peppermint oil has a high menthol content. Menthol chemically activates the cold-sensitive receptors on our skin. It is well known for the cooling sensation it provokes when inhaled or applied to the skin. Menthol also acts as a pain reliever and muscle relaxant by stimulating opioid receptors and blocking voltage-gated sodium channels that excite muscles. Peppermint oil also has a high concentration of pulegone, which is a natural but very strong and effective insecticide and pesticide.

Getting back to our perfumery notes, you can smell the middle notes once the top notes evaporate. The middle notes are often called the heart of the fragrance. They last longer than the top notes and strongly influence the base notes. The middle note we will use is tea-tree essential oil. A major chemical component in tea-tree oil is Terpinen-4-ol, which reduces inflammation by suppressing pro-inflammatory mediators in our body, and also kills microbes. Tea-tree oil effectively kills bacteria, fungi, and insects, and inhibits the development of viruses. Tea-tree oil is also an expectorant, meaning that it helps bring up sputum from the air passages, which is especially helpful in treating colds.

The base notes are the final fragrance notes that appear once the top notes are completely evaporated. The base notes provide the lasting impression. These rich notes linger on the surface for hours after the top notes have dissipated. We will use cedarwood essential oil as our base note. Cedrine and thujopsene, which are important chemicals in this oil act as expectorants, getting rid of coughs and phlegm, and as sedatives, inducing the release of serotonin and melatonin. Melatonin as you may know makes you calm and restores your sleep. Studies also show that inhalation of cedarwood oil protects your body against various types of food poisoning and fungal pathogens.


Okay, so we will be using cedarwood essential oil as a base note, tea-tree essential oil as a middle note, and peppermint essential oil as a top note. Cedarwood oil has a clear, balsamic smell, tea-tree oil has a light spicy smell, and peppermint oil has a powerful minty-fresh smell. As you apply this combination in your cleaner, the smell of peppermint will energize you. And when you’re back from work after a long tiring day, the lingering smell of cedarwood will relax you. What a perfect combination!

Now that we understand the chemical and biological benefits of these aromas, let’s make our product!
