Abstract
Description
DISINFECTANT COMPOSITION FIELD OF THE INVENTION The present invention relates to a disinfectant composition. More particularly, the invention relates to a disinfectant composition comprising at least 80% by weight of water and a cationic surfactant. When applied topically, the composition of the present invention unexpectedly provides superior antimicrobial benefits while simultaneously providing excellent antiviral activity. Such a composition results in a bacterial elimination rate of at least 2 and a viral inactivation rate of at least 2 in less than 3 minutes after topical application, even when formulated with little or no ethanol. The disinfectant composition of the present invention is particularly gentle on the skin. BACKGROUND OF THE INVENTION Consumer concern regarding microbial and viral contamination is typically high. This is because savvy consumers are aware of the negative impact such contaminants can have on their health. In fact, illnesses such as sinus, ear, and throat infections, as well as bronchitis, pneumonia, and whooping cough, are all linked to bacteria. Viruses, which are parasites, are commonly associated with the common cold, the flu, and certain types of pneumonia. Consumers generally recognize that washing their hands regularly and avoiding touching their faces are good practices for minimizing the risk of illness. During epidemics, such as the Ebola outbreak, and pandemics, such as those caused by influenza, cholera, and HIV / AIDS, consumers know that these serious infectious diseases are best overcome with regimens that include medical treatment, social distancing, wearing face masks, and extensive handwashing. Information provided by the Centers for Disease Control and Prevention suggests that the COVID-19 (coronavirus) pandemic is the direct result of a virus that is more efficient and severe than influenza and that spreads rapidly from person to person through respiratory droplets. During such a pandemic, consumers know that washing and sanitizing their hands regularly is in their best interest. Disinfectant products are commercially available and are typically supplied as gels containing at least 60% ethanol by weight. While these products are known to provide good antibacterial benefits after application, some consumers avoid using high-ethanol products because they can dry out the skin, weaken the epidermal barrier, and accelerate the aging process. There is growing interest in developing a disinfectant composition that provides excellent antimicrobial and antiviral benefits while being safe and gentle enough for unlimited use throughout the day. Given consumer demand, there is also growing interest in developing a disinfectant composition that provides soothing and moisturizing benefits when applied topically and is gentle enough for use on the face and even on the most delicate consumer, babies. This invention, therefore, is directed to a composition comprising at least 80% by weight of water and a cationic surfactant. The composition of the present invention, when applied topically, unexpectedly provides superior antimicrobial benefits. LQCQ iP / ZZΖ / E / YILI while simultaneously providing excellent antiviral activity. This composition results in a bacterial elimination rate of at least 2 and a viral inactivation rate of at least 2 in less than 3 minutes after topical application, even when formulated with little or no ethanol. The composition of the present invention is also suitable for disinfecting inanimate surfaces such as tables, kitchen counters, clothing, and the like. Additional information Efforts to manufacture compositions that provide antimicrobial benefits have been described.
