Ethyl alcohol or ethanol is one of the most common components of the home first aid kit. It can be purchased in pharmacies with two types of concentration: 70% and 96%. What is the difference between them? What is their effectiveness as a disinfectant? What can we use them for and why not? The Mentis Company clears the doubts.
The alcohol of 96% is the most concentrated alcohol that we are going to find commercialized, while that of 70% is a diluted alcohol and has a certain amount of water. The latter contains 70% ethanol and 30% water. Both types of alcohol are licensed for use as antiseptics for healthy skin.
The development of personal services for facial, body and ornamental aesthetics is related to the use of products for grooming, hygiene, cleaning, disinfection or sterilization. These products are used for the implementation of aseptic techniques in each of the work elements according to their risk, as well as with hand hygiene techniques. These products are regulated for their sanitary, quality control and sanitary surveillance regimes in relation to production, processing, packaging, sale, importation, storage and marketing.
To understand the applicable regulations for each of the hygiene, cleaning, disinfection or sterilization products, it is necessary to differentiate those for domestic use and from those for industrial use:
Alcohol-Based Cleaning and Hygiene Product for Industrial Use
The main function of alcohol-based cleaning products is to remove dirt and tend to take care of machinery and industrial facilities, hospitals, educational centers, etc., which meets the following requirements:
- Market: It is not intended for cleaning, hygiene and household products.
- Distribution and marketing system: It is aimed solely and exclusively at the industrial sector.
- Composition: The amount of active ingredient is different in terms of concentration, with respect to cleaning, hygiene and cleaning products for domestic use.
- Use of the product: It is carried out solely and exclusively through specialized machines, equipment or personnel.
Alcohol-Based Household Hygiene Product
The main function of this formula is to remove dirt and disinfect the environment and promote the care of household products, such as utensils, clothes or areas that will later be in contact with human beings. This definition does not include those products whose formulation has the main function of removing dirt, disinfecting and promoting the care of machinery and industrial and commercial facilities, educational centers, hospitals, public health and others for use in industrial processes.
Why is 70% alcohol preferable?
Another common mistake is to buy 96 alcohol in the belief that being more concentrated, it will act better against viruses and bacteria. The Mentis Company explains why this is not the case. The highest bactericidal activity is presented by 70, since it improves penetration into the bacterial protoplasm and is fast-acting, destroying 90% of the bacteria on the skin if it is kept moist during 2 minutes. On the other hand, the 96-year-old only manages to inactivate 75% of the bacteria. The latter is a purer alcohol and, therefore, it evaporates quickly and remains less time on the surface to be disinfected.
Keeping that in mind, The Mentis Company launched an oxygen-infused hand sanitizer, named as O2 Cleanser that kills 99.9% of the germs, bacteria and viruses on the surface. Hypochlorous Acid (HOCL), Natural sanitizer Nano-Colloidal Silver, plant derived sanitizer, disinfectant, and the Oxygen that is from the chemical production of Hypochlorous acid, were used to produce such a sanitizer. This product is a multi-purpose cleanser and can be used to purify the consumables, fruits and veggies.
These differences between 70% and 96% alcohol are also applicable to hydroalcoholic gels that since the coronavirus pandemic began have become essential for hand hygiene when it is not possible to wash them with soap and water. For a hydroalcoholic gel to have virucidal activity, the alcohol must be in the formula at a concentration between 60% and 95%. Within this range, 70% is generally considered the optimal concentration.
The experts comment that for hand hygiene you can simply use alcohol instead of hydroalcoholic gel. However, this option can make your hands drier. Our hands are going to suffer the dehydrating effect caused by alcohol, which is precisely the mechanism on which its effectiveness is based. This problem will be minimized if we use a gel or a hydroalcoholic lotion, since these types of formulations incorporate substances that reduce dehydration, such as glycerin, panthenol, plant extracts and even oils. The Mentis Company knew the circumstances of simply using alcohol on the surface. The company let everyone know that there is an alternative to keeping you and your loved ones healthy and clean, with the use of natural plant-based products.
Effectiveness of alcohol in surface disinfection
Alcohol can be used as an antiseptic on living tissue and also as a disinfectant on surfaces and objects. Other products for domestic use whose use could be more convenient, especially when it comes to disinfecting large surfaces. The volatility of alcohol causes it to evaporate relatively quickly, making it unnecessary to rinse when applied to a surface. But this apparent advantage is actually a disadvantage, since, by spending less time on the surface or object to be disinfected, its effectiveness decreases.
For this reason, The Mentis Company brought to the world, O2 Cleanser, that has the ability to not only sanitizes your skin, cleanses the surfaces, kills the 99.9% germs, but can also be used as an antiseptic.
