Hand Sanitiser FAQ

Q. What is a hand sanitiser?

A. A hand sanitiser is a liquid formulation that quickly kills, neutralises, or inhibits the growth of germs on physically clean hands, with the aim of avoiding transmission of germs.  Unlike hand cleansers, which clean physically dirty hands and require water to lather and then rinse off, hand sanitisers do not require water and can simply be left on the hands.

Q. Why would I need a hand sanitiser?

A. The U.S. Centers for Disease Control states that the number one way to prevent the spread of germs is by hand washing. Unfortunately, that is not always convenient. This product does not replace hand washing; it is a supplement. EcoHydra’s Antibacterial Hand Sanitiser kills germs instantly whilst moisturising the skin, thereby helping to prevent the spread of disease.   In fact, EcoHydra is more effective in use than alcohol-based products as well as being cheaper per application.

Q. Why is alcohol free significant?

A. Research findings from different studies show that alcohol-based hand sanitisers actually increase the number of bacteria on the skin the more they are used. Alcohol is a solvent that strips away oils that are important for water retention, and dries out the skin when it evaporates. This drying effect causes chapping of the skin, creating cracks and crevices where germs may become trapped or hidden. Even if an alcohol-based hand sanitiser has emollients, repeated use will still leave the skin dry, irritated, and more susceptible to invasion by germs. In addition, alcohol-based products are extremely flammable, which is highly undesirable, particularly in medical or school settings. Since EcoHydra’s Antibacterial Hand Sanitiser is water based, it won’t sting those small, unseen cuts or abrasions so common with school-age children and medical staff. It is highly effective while being very gentle on the skin.

Q. If I can still smell the alcohol-gel hand sanitiser, is it working?

A. Once an alcohol-based sanitiser has evaporated, its killing power is gone and this usually happens very soon after application. Some brands of alcohol-based sanitisers include strong fragrances to try to give a sense of security to the consumer...("as long as I can smell it, it must still be working")...however, as soon as the alcohol evaporates, it is no longer effective at killing germs. EcoHydra’s Antibacterial Hand Sanitiser has a documented persistence of residual activity for up to 4 hours

Q. Alcohol-gel instant hand sanitisers have emollients. Do these works as well as EcoHydra’s Antibacterial Hand Sanitiser in keeping the skin clean and soft?

A. When an alcohol sanitiser evaporates, it leaves behind the non-evaporable parts of the formula. Repeated use of alcohol based hand sanitisers leaves the skin dry and actually more susceptible to infiltration by disease-causing microorganisms. Some manufacturers of alcohol sanitiser have added emollients to these preparations to try and cut down on the drying effect of the alcohol. However, these emollients, when over-used, remain on the skin and become sticky after the alcohol portion of the product has evaporated. This leftover sticky emollient is unpleasant to feel, and can be transferred to food. Furthermore, it can act as a "germ magnet" and actually pick up germs from surrounding surfaces.

Q. How does the pricing of EcoHydra’s Antibacterial Hand Sanitiser compare to branded alcohol-containing hand sanitisers?

A. Pricing is very competitive with other hand sanitising solutions currently available. The cost per usage is generally significantly lower than branded alcohol-containing hand sanitisers. This is because EcoHydra’s Antibacterial Hand Sanitiser provides around three times the number of uses (based on volume required to achieve effectiveness).

Q. Do other companies manufacture a Benzalkonium Chloride (BAC) based sanitiser?

A. Yes. The active ingredient in EcoHydra’s Antibacterial Hand Sanitiser, BAC, is used by other companies but with limited success because its efficacy is easily neutralised. However, EcoHydra’s Antibacterial Hand Sanitiser incorporates a unique formulation that ensures lasting antimicrobial activity of BAC which has been proven through independent testing.

Many alcohol free products (as stated on their labels) take an excessively long time to dry, and some have added alcohol to speed up drying. Our product dries quickly without any alcohol.

Q. How effective is the EcoHydra® Alcohol Free Antibacterial Hand Sanitiser against harmful microorganisms?

A. The hand sanitiser is effective against a wide range of common germs, killing up to 99.9999% of disease-causing germs in as little as 15-30 seconds.

Q. How long is the EcoHydra® Alcohol Free Antibacterial Hand Sanitiser effective for?

A. In contrast to alcohol-based hand sanitisers, the EcoHydra® Alcohol Free Antibacterial Hand Sanitiser has residual germ-killing activity, and has been shown to continue to be active at destroying some common bacteria after application.  However, this residual activity is not permanent and regular re-application should be practised. 

Q. Does EcoHydra’s Antibacterial Hand Sanitiser work better with repeated use? Why?

A. The, EcoHydra® Alcohol Free Antibacterial Hand Sanitiser shows increased effectiveness with repeated use.  This is in contrast to alcohol-based sanitisers which show reduced effectiveness with repeated use. Whereas repeated use of alcohol creates skin crevices that can harbour germs, repeated use of the EcoHydra® Hand Sanitiser actually improves skin texture, thus making it progressively harder for germs to breed.

Q. How much of the EcoHydra® Alcohol Free Antibacterial Hand Sanitiser needs to be used?

A. An amount of 1-2 squirts (0.4-0.8ml) is sufficient to produce the desired effect.

Q. Is EcoHydra’s Antibacterial Hand Sanitiser supposed to be mixed with water or diluted before use?

A. No. EcoHydra’s Antibacterial Hand Sanitiser is formulated not to need dilution with water.

Q. Does EcoHydra’s Antibacterial Hand Sanitiser need to be wiped off after use?

A. No. EcoHydra’s Antibacterial Hand Sanitiser is meant to be left on the skin until it dries

Q. Will there be an aftertaste on food after using EcoHydra’s Antibacterial Hand Sanitiser before eating? 

A. No. Under conditions of normal use (hands dry after use), the product will not leave any noticeable aftertaste on food. The US  Food and Drug Administration requires that “an antimicrobial product applied to the hands is both:

  1. Safe and effective when applied to human skin, and
  2. A safe food additive when applied to bare hands that will come into direct contact with food.”

The EcoHydra Hand Sanitiser meets both of these criteria.

Q. Why do you say that using EcoHydra’s Antibacterial Hand Sanitiser will lower the rate of illness and absenteeism in schools, businesses and medical institutions?

A. A double-blind study was completed, which looked at the effectiveness of a BAC alcohol free instant hand sanitiser in reducing illness-related absenteeism during the height of a cold and flu season in several elementary schools in Southern California. The results of the test indicated that the overall illness was reduced by 33%, which shows that EcoHydra’s Antibacterial Hand Sanitiser is very effective at reducing costly absences due to gastrointestinal or respiratory illnesses. 

Q. What is the shelf life of the EcoHydra® Alcohol Free Antibacterial Hand Sanitiser?

A. EcoHydra® Alcohol Free Antibacterial Hand Sanitiser has a shelf life of three years.  We have a symbol on our label which denotes “Use within 18 months of opening”.
