Is Wex-Cide 128 toxic? What are its toxicity levels?

The Environmental Protection Agency (EPA) has established four toxicity categories for acute hazards of pesticide products based on the LD50 and LC50 values. Wex-Cide 128 is a phenolic disinfectant that falls under EPA Category IV, which indicates the least toxic potential. Studies conducted on animals showed that Wex-Cide 128 is not a primary irritant to skin or eyes and does not induce sensitization in guinea pigs. In an acute oral toxicity study on female rats, all rats survived and gained weight during the study, and the acute oral LD50 of Wex-Cide 128 is greater than 5,000 milligrams per kilogram of body weight. It’s important to note that all studies in this document were conducted at use dilution.

Is Wex-Cide 128 effective as a non-human primate disinfectant?

Wex-Cide 128 is a disinfectant concentrate developed to provide a less toxic alternative to commonly used disinfectants in the human primate healthcare environment. It is an intermediate level disinfectant (Tuberculocidal) with efficacy in the presence of 5% organic soil load. The concentrate is not orally or dermally toxic, nor a skin sensitizer, making it safe for use around non-human primates, caregivers and the environment. The diluted solution is EPA Toxicity Category IV, and no precautionary statements or signal words are required. For full efficacy, please refer to the full efficacy sheet under “additional downloads” at the bottom of the page.

What are phenolic derivatives and how are they used in disinfectants?

Phenolic derivatives, also known as “phenolics,” are a group of active ingredients that are used in disinfectant formulations for household, industrial, and veterinary applications, as well as for post-harvest preservation of fruit and vegetables. These derivatives are derived from phenol, also known as carbolic acid, which was historically used as a germicide in hospitals. However, modern phenolic derivatives have improved antimicrobial properties and are less harmful to humans and the environment.
