Health and Safety Concerns

With regard to the ingredients—which are not fully listed on the product label, but are on the Material Safety Data Sheet (MSDS) — boric acid stands out as a safety concern because it is considered of moderate acute toxicity. Unfortunately, whether it is a highly concentrated ingredient in the product or not is difficult to tell. The other two ingredients don't raise any red flags with regard to safety and health effects.

Under normal usage, this product does not appear to have any adverse health effects according to the product MSDS. However, upon direct contact with the eyes, it can cause redness, burning, and watering. Repeated contact with the skin can cause problems, such as a skin rash. In addition, breathing in dust from the product can irritate the respiratory tract resulting in symptoms, such as coughing. Also, the MSDS notes that ingesting the product may be harmful.

First-aid measures noted on the MSDS and the product label differ slightly in some cases. If eye contact occurs, the directions on the packaging note to flush the eyes with water for 15 minutes. In addition, the MSDS notes to contact an ophthalmologist. If swallowed, the MSDS recommends drinking two glasses of water or milk immediately and then seeking medical attention. The label doesn't mention anything about drinking liquids but suggests to immediately contact a Poison Control Center or doctor.

If skin contact occurs, rinsing well with water is recommended on the product label; whereas the MSDS suggests using soap and water and then a moisturizing cream if needed for dryness. If any irritation persists, seek medical attention. Finally, the MSDS notes that if excessive amounts of product dust are inhaled, to get fresh air and seek medical attention if a cough or other symptoms develop. Vomiting is not recommended.

This product is safe for septic systems, according to the manufacturer.
