Hand Sanitisers: The Best Alternative to Handwashing

Date Posted: 1 March 2021

Washing your hands is the most effective way to protect yourself from viruses that cause diseases like the coronavirus. However, when soap and water are not available, using an alcohol-based hand sanitiser becomes the next best option.

Experts strongly recommend washing your hands with soap and water as the primary method for preventing the spread of the COVID-19 virus. It's a simple yet powerful habit that can significantly reduce the risk of infection. But what do you do when you're out and about, without access to a sink or clean water? That’s where hand sanitisers come in handy.

How effective are hand sanitisers in protecting against dangerous viruses like the coronavirus? Can they serve as a good alternative for people who haven’t been vaccinated? And what’s the correct way to use them? Keep reading to find out all the answers.

Hand Sanitiser and Hand Hygiene

In today’s world, where health concerns are at the forefront, maintaining good hygiene has become more important than ever. Whether you're a healthcare worker or just an everyday person, developing strong hand hygiene habits can help prevent the spread of germs and viruses, including the coronavirus.

Studies show that our hands are one of the main ways infections spread—from common colds to serious illnesses like SARS and the novel coronavirus. This makes regular handwashing essential. While washing with soap and water is the gold standard, it's not always practical in every situation. That's why having a reliable hand sanitiser on hand is crucial during times of public health emergencies.

Alcohol-based hand sanitisers are a convenient and effective alternative when soap and water aren't available. They can be carried in your pocket, purse, or bag, making it easy to maintain cleanliness even when you're on the go.

Hand Sanitiser vs Soap and Water

The key difference between soap and water and hand sanitiser is that the latter doesn't physically remove germs—it kills them. When you wash your hands with soap and water, the soap helps break down the outer layer of viruses and bacteria, and the water rinses them away. This process is highly effective but requires access to a sink and clean water.

Alcohol-based hand sanitisers, on the other hand, work by killing germs on contact. They are especially effective against the coronavirus because the alcohol content (usually 60–75%) disrupts the virus's structure, making it inactive. These products are also very convenient, as they can be used anytime and anywhere.

While handwashing is the best method, there are situations where it's simply not possible. In those cases, using a hand sanitiser is a great backup. For example, if you're visiting someone in the hospital, it's important to sanitise your hands before entering and after leaving to avoid bringing or spreading germs. Similarly, when interacting with people who have weakened immune systems—like the elderly or young children—it's wise to use a hand sanitiser to keep everyone safe.

Finding An Effective Hand Sanitiser

With so many hand sanitiser options on the market, it can be hard to know which one is right for you. Should you choose an alcohol-free version or go for one containing ethanol or isopropyl alcohol?

Alcohol-free hand sanitisers typically contain quaternary ammonium compounds, which are less effective at killing germs but gentler on the skin. On the other hand, alcohol-based versions are more powerful, with concentrations of 60–75% alcohol, often combined with natural ingredients like tea tree oil or aloe vera to make them more pleasant to use.

Ultimately, the choice depends on your personal preference and needs. However, it's important to follow expert recommendations to ensure you're using a product that works effectively.

Which Hand Sanitiser Should You Buy?

Not all hand sanitisers are created equal. Some are more effective than others, so it's important to choose wisely. According to the CDC and health experts, the best hand sanitisers contain at least 60% alcohol. Those with lower alcohol content may not be as effective at killing germs and viruses.

For maximum effectiveness against the coronavirus, look for a hand sanitiser with at least 70% alcohol. Studies have shown that products with alcohol concentrations between 60–95% are more effective at killing viruses and bacteria compared to non-alcohol-based alternatives.

Avoid hand sanitisers that contain benzalkonium chloride, as they are less effective against certain pathogens. Instead, opt for products with proven alcohol-based formulas. Sydney Solvents offers a range of high-quality hand sanitisers that are effective, gentle on the skin, and available in scents like bubblegum and lemon to keep your hands fresh and clean.

How to Use Hand Sanitisers

Hand sanitisers only work if used correctly. Here’s how to use them properly to ensure they kill germs and viruses effectively:

  1. Pour the recommended amount into the palm of your hand. Make sure it covers all surfaces of both hands.
  2. Spread the sanitiser over your hands, focusing on fingertips and palms, which are touched the most.
  3. Rub your hands together for at least 20 seconds or until they are completely dry.
  4. Do not wipe off the sanitiser. Let it dry naturally on your skin.

Summary

Washing your hands with soap and water is the most effective way to protect against viruses like the coronavirus. However, when this isn’t possible, using an alcohol-based hand sanitiser with at least 60% alcohol is the next best option. These products are convenient, effective, and ideal for use when you’re out and about. Whether you're shopping, traveling, or visiting loved ones, hand sanitisers are a smart addition to your daily routine.

Manual Tapping Machine

A Manual Tapping Machine is a useful tool for creating internal threads in workpieces. It is operated manually, providing a cost-effective solution for small-scale production or occasional tapping tasks.
The Manual Tapping Machine typically consists of a frame, a spindle, and a handle. The frame provides stability and support, while the spindle holds the tap and rotates it to cut the threads. The handle is used to manually turn the spindle and apply the necessary force for tapping.
One type of Manual Tapping Machine is the Double Spindle Drilling And Tapping Machine. This machine combines the functions of drilling and tapping, allowing for efficient processing of workpieces. With two spindles, it can perform both operations simultaneously, saving time and increasing productivity.
The Table Top Tapping Machine is another option. As the name suggests, it is designed to be placed on a table or workbench. It is compact and easy to use, making it suitable for small workshops or hobbyists. This type of machine is often used for light-duty tapping tasks.
The Vertical Tapping Machine is a more advanced version. It has a vertical orientation, which provides better stability and accuracy during tapping. The vertical design also allows for easier access to the workpiece and more precise control over the tapping process.
In conclusion, a Manual Tapping Machine is a valuable tool for creating internal threads. With different types such as the Double Spindle Drilling And Tapping Machine, Table Top Tapping Machine, and Vertical Tapping Machine, there are options available to suit various needs and applications. Whether for small-scale production or DIY projects, these machines can help achieve accurate and efficient tapping results.
