- The Government of Canada conducted a science-based evaluation, called a screening assessment, to address the potential for harm to Canadians and to the environment from dimethoxymethane.
- Under the Canadian Environmental Protection Act, 1999 (CEPA 1999) the risk posed by a substance is determined by considering both its hazardous properties (its potential to cause adverse human health or ecological effects) and the amount of exposure there is to people and the environment. A substance may have hazardous properties; however, the risk to human health or to the environment may be low depending upon the level of exposure.
- More information on assessing risk can be found in the Overview of Risk Assessment and related fact sheets, particularly on Types of Risk Assessment Documents and the Risk Assessment Toolbox.
- The ecological hazard and exposure potentials of this substance were classified using the Ecological Risk Classification of Organic Substances Approach.
- As a result of the draft screening assessment, the Government is proposing that dimethoxymethane is not harmful to human health or to the environment at current levels of exposure.
About this substance
- The screening assessment summarized here focuses on the substance methane, dimethoxy-, also referred to as dimethoxymethane. This substance was assessed under the Chemicals Management Plan (CMP).
- According to the information gathered by the Government, this substance occurs naturally in a limited number of food products, such as cooked shrimp and strawberries.
- In Canada, dimethoxymethane is mainly used as a solvent (that is, used to dissolve other substances) in products available to consumers including cosmetics, cleaning products, paints and coatings, spray adhesives, and batteries.
Human and ecological exposures
- Canadians may be exposed to this substance through its natural presence in food and from products available to consumers, such as cosmetics, cleaning products, and paints.
- According to information considered under the Ecological Risk Classification of Organic Substances Approach, dimethoxymethane was identified as having a low ecological exposure potential.
Key health and ecological effects (hazard)
- Dimethoxymethane is not considered to have hazardous properties for human health.
- According to information considered under the Ecological Risk Classification of Organic Substances Approach, dimethoxymethane was identified as having a low ecological hazard potential.
Risk assessment outcomes
- On the basis of the information presented in the draft screening assessment, the risk to human health from dimethoxymethane is low.
- Based upon the outcome of the Ecological Risk Classification of Organic Substances Approach, dimethoxymethane is considered unlikely to cause ecological harm.
- The Government of Canada published the Draft Screening Assessment for Dimethoxymethane on July 20, 2019. The public are invited to comment on the assessment during the 60-day public comment period ending on September 18, 2019.
Proposed screening assessment conclusions
- As a result of the draft screening assessment, the Government is proposing that dimethoxymethane is not harmful to human health at current levels of exposure, and that it is not entering the environment at concentrations that are harmful to the environment.
- Dimethoxymethane may be found in products available to consumers. Canadians should follow any safety warnings and directions on product labels and dispose of productsresponsibly.
- Canadians who may be exposed to dimethoxymethane in the workplace can consult with their employer and an occupational health and safety (OHS) representative about safe handling practices, applicable laws, and requirements under OHS legislation and the Workplace Hazardous Materials Information System (WHMIS).
