Pure Hand Instant Hand Sanitizer Gel, based on the active ingredient Benzalkonium Chloride, is a unique gel formulation that features exceptional skin feel, conditioning and moisturizing properties. The efficacy of this product has been confirmed to reduce S. aureus 99.999% in as little as 15 seconds.

 

A wash off Benzalkonium Chloride offering in the ranges of 0.1-0.13% is recognized under the 1994 TFM for Antiseptic Drug Products when making claims against bacteria. Its leave-on or hand sanitizer use without a rinse is recognized and covered by the OTC Drug Review for antiseptic hand wash, healthcare-personnel hand wash and surgical scrub uses, with the through requisite prior evidence of it being marketed for a material time and extent prior to December 1975 in the United States for these uses. Therefore, until a final antiseptic monograph is issued and establishes Benzalkonium Chloride in Category I or Category II its (0.1-0.13%) remains in Category III and is allowed to be marketed as a wash-off (rinse) offering per the TFM or as a leave on because of being in the market prior to December 1975, i.e. Bactine®, developed in 1947 and introduced in 1950.

Why Benzalkonium chloride based Hand Sanitizers?

History- Benzalkonium chloride is an alcohol-free antimicrobial compound that has been widely used in the health care industry for more than 60 years in formulas for preservatives, surface cleaners, sterilizing agents, and leave-on, FDA Monograph anti-bacterial skin treatment products. The chemical properties of benzalkonium chloride make it a good candidate for persistent antimicrobial activity in mammalian tissue.  The Cosmetic Ingredient Review (CIR) Expert panel concludes that benzalkonium chloride is safe as a cosmetic ingredient at 0.1%.

What are the advantages of Benzalkonium chloride-based over Alcohol-based Hand Sanitizers?

Benzalkonium chloride based Hand Sanitizers have several distinct advantages over alcohol-based hand sanitizers. While both product forms are FDA Monograph for leave-on products, fast acting and allow for use without water or towels, benzalkonium chloride based products are non-flammable, non-damaging to skin, are persistent, and will not stain clothing or flooring.
