How does Aerosol spray work and what’s inside?

Good day, all.

There are a lot of fluctuations in our global situation. We hope everyone stays well and healthy.

During this time, we have received many inquiries from the aerosol industry. Unfortunately, it seems the price hike and supply shortage is going on for Molecular Sieve. However, you might be wondering what Molecular Sieve is and why the aerosol industry needs it? It is actually in our daily life, but we might not have noticed it before. Please let us walk you through the article about Molecular Sieve for the aerosol industry.

What is aerosol?

Firstly, the aerosol industry might sound too technical and give you a complicated feeling. To make it simple, dust or fog is an example of natural aerosols. It is a suspension of fine solid particles or liquid droplets in air or any gas. Mist also one of it.

How is it being used in the aerosol industry?

For industrial, we create synthetic aerosols by making use of the same physics. The suspension of fine particles, liquid or gas. Looking into the aerosol industry (aka spray industry), they make use of it to contain gas or liquid at room temperature. It is simply poured into the can and sealed. The popular propellant is liquefied gas. It is simply poured into the can, pumped at high pressure, and sealed.

Under a high level of pressure, liquid cannot turn into gas. Therefore, when you press the button for spraying, the valve is open, pressure becomes reduced. This liquid propellant will boil and form a gas layer on top. Then, it will push the real liquid product mixing with some of the liquid propellant up the tube to the nozzle. If you ever hear the ball rolling sounds when shaking the spray can, that “pea” helps to mix the liquid product and liquid propellant well together. And, the product will be pushed as a fine mist for us. It is one liquid pushing after another and getting shaped by the nozzle.

And, why do we need Molecular Sieve for the aerosol industry?

Liquefied gas is being used as liquid propellant that’s also mixing with the product. The gas is LPG (Liquified Petroleum Gas) which comes from natural source, but it shouldn’t be smelly for consumers. So, here is where Molecular Sieve comes.

Molecular Sieve is a desiccant that has very small holes which act as a filter to let only some smaller and equaled molecules go in, and the bigger ones cannot. Mercaptan is a sulfur compound that exists in LPG. I only mentioned sulfur compounds, but I suppose you could imagine that the smell is not very pleasant. Therefore, aerosol makers need to use Molecular Sieve to remove Mercaptan from LPG.

The general name of Molecular Sieve would be 3A, 4A, 5A and 13X. 13X is the most popular to be used in the aerosol industry to absorb Mercaptan smell for a nice deodorant, perfumes and other products.

SHODEX Chromato News October 2022: Stay Updated with New Applications

New Application Data on Shodex.com

Separation of Ascorbic Acid and Isoascorbic Acid (DE-413) >> Application Note

Ascorbic acid and isoascorbic acid were separatd using two columns of RSpak DE-413 (a column for polymer-based reversed phase chromatography). The calibration curve of ascorbic acid and isoascorbic acid shows good linearity respectively in the range from 1 to 100 μg/mL. 

Analysis of Oligonucleotides and Their Impurities (1) Truncated Oligonucleotides (VN-50 2D) >> Application Note

In R&D and QC of nucleic acid drugs such as antisense nucleic acids require development of analytical methods that separate the target synthetic oligonucleotide from its impurities as much as possible. In this application, four compounds were analyzed using HILICpak VN-50 2D, a polymer-based HILIC column. The four compounds were the target synthetic oligo-DNA (20mer; n nucleotides) and its three analogs with 1 to 3 truncated nucleotides (19mer, 18mer, and 17mer; n-1, n-2, and n-3 nucleotides respectively).

Under HILIC mode, the higher the hydrophilicity, the stronger the retention becomes. Thus, the four oligo-DNAs eluted in the order of smaller to larger oligomer. The application developed here does not require a use of ion-pairing reagent nor highly concentrated salt in the eluent. Therefore, it is suitable for LC/MS analysis of oligonucleotides.

Analysis of Oligonucleotides and Their Impurities (2) Base Alteration (VN-50 2D) >> Application Note

In R&D and QC of nucleic acid drugs such as antisense nucleic acids require development of analytical methods that separate the target synthetic oligonucleotide from its impurities as much as possible. In this application, four compounds were analyzed using HILICpak VN-50 2D, a polymer-based HILIC column. The four compounds were 20mer synthetic oligo-DNAs: one with the target base sequence and its three analogs with 1 to 3 base alterations.

By having different bases make their hydrophilicities different from each other. Four synthetic oligo-DNAs were separated by HILIC mode using this hydrophilicity differences. The application developed here does not require a use of ion-pairing reagent nor highly concentrated salt in the eluent. Therefore, it is suitable for LC/MS analysis of oligonucleotides.

What we learned from exhibiting in Thailand Lab 2022.

news | 06 October 2022
Tag: shodex thailand

Hi readers. Good day!

Greeting from us, Showa Denko Singapore. The other day, we exhibited our SHODEX™ HPLC Column booth at Thailand Lab International 2022, a laboratory related exhibition, for three days. This year, I have a lot of good experiences with users at our booth. With this exhibition, I made some new discoveries about lab users, and good tips about exhibiting at big events. Let’s go through together what I have learnt this time.

Tips for hot booth

  • A focus topic

Mostly, a popular booth is a booth that focuses on only an attractive topic. In Thailand, this time it was popular with a Cannabis-themed booth. Cannabis has become a trending topic for Thai people since the regulations eased for a while. I can easily see it anywhere from the roadside to a specialist shop. Our local partner who also exhibited the Cannabis booth (about analysis equipment 😊) said almost 200 companies have started manufacturing it so far. No surprise that Cannabis could be an eye-catching topic for booth display this year.

  • Interactivity

Also, the hot booths mostly have an interactive display or activities with customers, i.e. moving display, games and so on. Definitely, you can adapt this concept to your product/business showcase too.

Customer’s experience

At this time, about 100 users visited our booth. After full 3 days, I found some interesting habits of each customer. I think it could be useful for your business too.

  • 90% of the participants were women

From my working experience in Thailand, 90% of the staff/customers or even your colleagues will be women. Also, this time women are the majority among lab users.

  • Women look at the table, while men look at the posters.

In the most of the movements, women tend to look at the display table first. Maybe it is eye-level or a more eye-catching display on the table. While, men’s first look will be on the poster at the booth panels at an unreachable distance.

FYI, we have touchable product mock-up and cute Japanese dolls at the table display, while more academic posters are black-themed and quite far in distance.

  • Fewer visitors come inside the booth.

The nature of the visitors only walk past the booth. We found that only 5% of visitors came inside the booth. So, we have learned that the booth panels (or posters) with too many fonts might not be useful for both us and visitors.

Based on this hypothesis, we made improvements such as adding more tables and increasing the number of displays (more colorful displays for eye-catching) from the second day onwards. As a result, the number of visitors increased and we were able to gather more information and various opinions about our product too.

Summary

At this exhibition, we achieved the following:

  • Get the voice of the user
  • Explore market trends
  • Get hints for future marketing plans
  • Notes to improve next year’s exhibition

Through this experience, I would like to take on new challenges next year,

  • To have special feature in our booth
  • Fewer fonts to make visitors understand our product/service better
  • Novelty goods for women 

Showa Denko Singapore is working to understand more about our customers to improve their experience with our service and product.

If you have any good marketing tips, please feel free to let us know too. >> contact us.

Thank you for reading to the end!!
