The Chemical Directory / Toxic Household Chemicals Safety Guide
On this page you will find a list of the chemicals that you may be using in home cleaning or used by some professional cleaners.
Acetone – Flammable volatile liquid with distinctive odor. Reacts explosively with hydrogen peroxide. Irritating to eyes, respiratory tract and skin. May be absorbed by inhalation. Can cause changes in liver’s ability to metabolize chemicals, kidney damage, dizziness, sedation and coma.
Acids – Solutions with a pH range between 0 to 6.9. They are corrosive between pH 0 and 2.0 and produce severe burns on contact. See also pH. Uses: Many cleaning products (e.g., delimers, bathroom cleaners, bowl cleaners) are acidic.
Acute health effects – Effects which occur rapidly as a result of short-term (usually less than 24 hours) exposures. Acute effects are usually of short duration, but long term effects can occur after one exposure. Examples include irritation, corrosivity, chemicallyinduced unconsciousness (narcosis), or death.
Aerosol propellants – Gases used to pressurize spray products. Chloroflouorocarbons, which deplete the ozone layer, may be found in old cleaning products. Today other chemicals, such as isobutane, a petroleum product may be used. Hydrocarbon propellants like isobutane contribute to smog problems because of their contribution to tropospheric (ground level) ozone formation .

pH – A measure of the acidity or alkalinity of a solution. A pH of 7 is considered neutral. A pH greater than 7 indicates alkalinity. A pH less than 7 indicates acidity. In the absence of specific test data on irritation, pH provides some insight into whether a product will be corrosive or cause irritation. Products with very high or very low pH (11.5 or 2) should be assumed to be corrosive. High or low pH values (e.g., between 9 and 11, or between 4 and 2) indicate the product would be more irritating than neutral pH products where the pH is closer to 7.
