What You'll Learn
Effectiveness against germs and bacteria
Ethyl alcohol, also known as ethanol, is an effective ingredient in hand sanitizers for eliminating germs and bacteria. According to the Centers for Disease Control and Prevention (CDC), an alcohol concentration of between 60% and 90% is optimal for disinfection purposes. This concentration range ensures the effective elimination of a broad range of germs, including common bacteria such as E. coli, Staphylococcus aureus, and Salmonella.
The effectiveness of ethyl alcohol in killing bacteria is attributed to its ability to rapidly denature proteins. This mechanism is enhanced when ethyl alcohol is mixed with water, as proteins are denatured more quickly in aqueous solutions. At concentrations above 60%, ethyl alcohol effectively kills microbes on the skin and surfaces, including bacteria, viruses, and fungi.
The CDC has specifically noted the efficacy of 70% ethyl alcohol in killing certain organisms, such as Cryptococcus neoformans, Blastomyces dermatitidis, Coccidioides immitis, and Histoplasma capsulatum. This concentration is also effective against the new coronavirus that causes COVID-19.
While ethyl alcohol is an excellent disinfectant, it is important to note that it is not a sterilant. Alcohols lack sporicidal action and cannot penetrate protein-rich materials, making them unsuitable for sterilizing medical and surgical instruments. Additionally, alcohol-based sanitizers are not meant to be consumed, as they will not destroy pathogens inside the body.
In summary, ethyl alcohol at a concentration of 70% is highly effective at killing germs and bacteria. It is a common ingredient in hand sanitizers due to its ability to rapidly disinfect and its broad-spectrum antimicrobial activity. However, it should be used topically and not as a substitute for internal disinfection.

Moisturisers and skin safety
The use of hand sanitizers has become a common practice to maintain hand hygiene and prevent the spread of viruses, especially during the COVID-19 pandemic. While hand sanitizers are effective in killing bacteria and viruses, excessive use can lead to skin problems and health issues if not used appropriately.
Hand sanitizers, particularly alcohol-based ones, can strip moisture from the skin, damaging the hand microbiome and causing the skin barrier to deteriorate. This can result in dry, cracked, or itchy skin. To counter these effects, it is essential to prioritize skin safety and regularly moisturize the hands.
Moisturizers play a crucial role in maintaining skin health and protecting the skin barrier. They help lock in moisture, preventing water loss and keeping the skin supple and hydrated. When choosing a moisturizer, look for ingredients like glycerol, which has been suggested to maintain antimicrobial activity while offering skin protection. Other ingredients with emollient properties, such as dimethicone, isopropyl isostearate, and castor oil, can also be beneficial by smoothing the skin and filling the spaces between skin flakes.
Additionally, some hand sanitizers in the market already contain moisturizing agents, helping to combat the drying effects of the alcohol. For example, Lotus Aroma's hand gel and spray sanitizers contain organic aloe vera, which has moisturizing properties. La Roche-Posay's antibacterial hand-sanitizing gel is another option, offering a fragrance-free formula that eliminates bacteria and germs without drying out the skin.
When using hand sanitizers, it is important to follow the recommended guidelines and allow sufficient contact time for the product to effectively kill germs and viruses. By maintaining proper usage and incorporating moisturizers into your hand care routine, you can effectively balance sanitization and skin safety.

Manufacturing location
Ethyl alcohol, also known as ethanol, is a safe and effective ingredient in hand sanitizers when used as directed. It is recommended that hand sanitizers contain at least 60% alcohol to be effective in killing germs. Concentrations between 60% and 95% are most effective, and ethyl alcohol at 70% concentration falls within this range.
Ethyl alcohol-based hand sanitizers are widely available and used, particularly in clinical settings such as hospitals. During the COVID-19 pandemic, ethyl alcohol 70% was listed by the EPA as an effective disinfectant against the SARS-CoV-2 virus.
Parchem, a distributor of ethyl alcohol 70%, supplies the ingredient in bulk to various sectors, including government, military, and healthcare. They adhere to the National Association of Chemical Distributors (NACD) guidelines for the safe handling, distribution, and delivery of hazardous and non-hazardous materials, ensuring environmental and human safety.
The manufacturing location of ethyl alcohol 70% for hand sanitizers is not limited to one specific place, as it is a widely used ingredient. Companies like Parchem distribute this product in bulk to various sectors, indicating a broad reach and supply chain. The CDC provides guidelines and recommendations for the use of hand sanitizers in community settings, but the specific manufacturing locations of ethyl alcohol 70% can vary depending on regional demands and supply chain logistics.

Absorption and texture
Ethyl alcohol-based hand sanitizers are safe when used as directed. They are effective at killing 99.9% of disease-causing germs and bacteria. However, they are most effective when used on hands that are only slightly soiled. When hands are heavily soiled or greasy, handwashing with soap and water is recommended.
The CDC recommends washing hands with soap and water whenever possible because it reduces all types of germs and chemicals on hands. If soap and water are unavailable, hand sanitizers with at least 60% alcohol content are recommended. Alcohol-based hand sanitizers can quickly reduce the number of microbes on hands, but they do not eliminate all types of germs.
Ethyl alcohol hand sanitizers are typically absorbed quickly by the skin, leaving a smooth and dry texture. Some hand sanitizers may also contain moisturizing agents, such as aloe vera, to prevent dryness and leave hands feeling soft and supple.
The absorption and texture of ethyl alcohol hand sanitizer can vary depending on the specific formulation and additional ingredients. Some hand sanitizers may leave a sticky or tacky residue, while others may be designed to be fast-absorbing and non-greasy.
It is important to note that while ethyl alcohol hand sanitizers are generally safe and effective, they should be kept out of the reach of young children. In cases of ingestion, hand sanitizers can cause alcohol poisoning. Always supervise children when using hand sanitizers and ensure they understand the importance of proper hand hygiene.

Scent
Ethyl alcohol, also known as ethanol, is a clear, colourless liquid with a distinct alcoholic scent. It is typically safe to use and is an effective disinfectant against germs, bacteria, and viruses.
When used in hand sanitizers, ethyl alcohol is recommended at concentrations of at least 60% to ensure effectiveness in reducing germs. Concentrations above 80% are generally not suitable for disinfecting purposes as they may be too strong and could be flammable.
The scent of ethyl alcohol in hand sanitizers can vary depending on the brand and added ingredients. Some hand sanitizers may have a strong alcoholic scent, while others may have added fragrances to mask the alcoholic smell and provide a more pleasant sensory experience.
For example, some hand sanitizers may have a citrus scent, leaving your hands smelling fresh and clean. Other common fragrances include floral or fruity scents, such as lavender or strawberry. These added fragrances not only enhance the sensory experience but also may appeal to personal preferences, making hand sanitizing a more enjoyable part of personal hygiene routines.
It is important to note that while scent can be an appealing factor in hand sanitizer selection, it should not be the sole criterion. The effectiveness and safety of the product should always be the primary considerations. Additionally, some individuals may have sensitive skin or preferences for unscented products, so choosing a hand sanitizer without added fragrances can also be an option.
