Quat solutions contain anti-rust ingredients, but leaving them in the solution too long can cause damage. Phenolics are powerful tuberculocidal disinfectants. They have a very high pH and can cause damage to the skin and eyes.

Does phenolic disinfectant have a low pH?

When used as directed, LOW pH PHENOLIC 256 is strong enough to kill a broad spectrum of pathogenic bacteria, yet it is mild enough to have no hannful effects on the surface being disinfected, when used as directed.

What do phenolic disinfectants have?

Phenolic compounds used as antiseptics or disinfectants include pure phenol and substitution products with halogens and alkyl groups. They act to denature and coagulate proteins and are general protoplasmic poisons. Phenol (carbolic acid) is one of the oldest antiseptic agents.

What are the drawbacks of phenolic disinfectants?

Phenol is no longer used as a disinfectant due to its toxicity and carcinogenicity. Skin absorption and irritation is still a possibility with the other compounds still currently used. They don't kill bacteria spores, and the presence of organic material can decrease their effectiveness.

What is the advantage of using phenolics as disinfectants?

Phenolics are stable, long-acting disinfectants that denature proteins and disrupt membranes. They are commonly found in household cleaners, mouthwashes, and hospital disinfectants, and are also used to preserve harvested crops.
