Why is the EPA Registration Number on the bottle label so important to me?

Here's why:

While the EPA (Environmental Protection Agency) does not endorse or recommend any product, the EPA registration number on the label means that the agency has reviewed the product’s formula, its active and inert ingredients and that the product will do what it claims.  And those are our expectations, aren't they?  That the product will do what the label says, and it's safe? According to agency representatives in a Nails Magazine interview, “The EPA registrations means a product should do what the label says and should not pose an unreasonable hazard to your health.” In addition, member guidelines of the International Nail Technician Association’s state, “In all cases, we recommend using an EPA registered hospital liquid disinfectant that the label claims is a bactericide, viricide and fungicide.”

Check out this snippet from a label on a Gallon of One-Step Disinfectant:

"Disinfectant, Non-Food Contact Sanitizer, Cleaner, Mildewstat, vVirucide for Hospitals, Nursing Homes, Whirlpool, Institutional, Iindustrial Use. This product is for use on hard, non-porous surfaces in Barber / Beauty Shops and Salons. This product can be used on hard, non-porous surfaces such as footbath surfaces. Effective as a disinfectant in hard water up to 400ppm hardness  (calculated as CaCO3) in the presence of 5% serum contamination."

So, the bottom line is this:  Whether you use One Step Disinfectant by Splish Splash or some other disinfectant, be certain it's an EPA registered disinfectant!
