SNAc for Rhamnose-containing Glycolipids
Canada Gazette, Part I, Volume 160, Number 5: GOVERNMENT NOTICES
A Significant New Activity (SNAc) notice applies to glycolipids, rhamnose-containing, Pseudomonas putida‑fermented (CAS 2892303-59-0), requiring 90 days' advance notification before certain new uses. The notice targets uses in non-oral cosmetics and specific consumer soaps/detergents above 2% by weight (with a transitional 100 kg threshold until 2027) and requires toxicity and exposure information including eye‑irritation data.
Summary
Summary#
This notice—Significant New Activity Notice No. 22299 under the Canadian Environmental Protection Act, 1999—applies to the substance glycolipids, rhamnose-contg., Pseudomonas putida‑fermented, from D‑glucose, sodium salts (CAS 2892303-59-0). It is in force as of January 31, 2026 and requires advance notification and information when the substance is used in certain consumer cleaning products or cosmetics at higher concentrations.
What it does#
- Defines a “significant new activity” for the substance when it is used in the manufacture or sale of products where the substance is present at more than 2% by weight:
- a cosmetic (except an oral cosmetic),
- a liquid laundry soap or detergent that is a consumer product,
- a hand dish soap or hand dish detergent.
- Requires a person proposing one of those uses to send a notification and supporting data to the Minister of the Environment at least 90 days before starting the activity.
- Lists specific information that must be provided, including:
- the planned annual quantity to be used,
- the function of the substance in the product,
- available toxicity and exposure information,
- studies on eye irritation at concentrations from greater than 2% by weight up to less than 9% by weight.
- Excludes certain uses from the notice:
- use as a research and development substance or a site‑limited intermediate,
- manufacture of products that are for export only,
- uses already regulated under other federal laws named in the notice.
- Includes a transitional threshold until January 31, 2027: the notice applies only if the proposed use or distribution for sale involves more than 100 kg of the substance during that period.
- States that the Ministers of the Environment and Health will assess the submitted information within 90 days of receiving a complete notification.
Who's affected#
- Manufacturers, importers, formulators, and distributors who handle glycolipids, rhamnose‑contg., Pseudomonas putida‑fermented, from D‑glucose, sodium salts for use in:
- non‑oral cosmetics,
- liquid laundry soaps/detergents sold as consumer products,
- hand dish soaps/detergents.
- Retailers and anyone who would sell or distribute products that contain the substance at concentrations above 2% by weight.
- Organizations doing research or making export‑only products are generally not affected by these rules.
- The notice also affects anyone who would transfer physical possession of the substance; they may need to notify downstream recipients in some situations (the notice sets out when notification is not required).
Why it matters#
- The government has flagged these new uses because it believes they could change how people or the environment are exposed to the substance and that such changes might lead to harm. The notice makes companies explain and justify planned uses before they start.
- For companies: this adds a pre‑use reporting step, extra testing (for example, eye‑irritation data), and a possible waiting period while regulators assess risk.
- For consumers: it means regulators are checking whether this ingredient is safe in everyday products like cosmetics and soaps before broader use or sale is allowed.
- For public health and regulators: the information gathered will guide whether the substance needs limits, labeling, or other controls.
