  • Toxicity Summary: While quaternium-10 itself is not toxic, it is a nitrosating agent. Nitrosating agents may decompose and/or react to cause nitrosamine contamination. Nitrosamines are produced from secondary amines and amides in the presence of nitrite ions and are believed to be carcinogenic. Once in the body, nitrosamines are activated by cytochrome P-450 enzymes. They are then believed to induce their carcinogenic effects by forming DNA adducts at the N- and O-atoms.

Verification checklist

  1. Search exact identity across Schedules 4–8.
  2. Apply use, concentration and warning conditions.
  3. Check hazardous-substance classification and Group Standard scope.
  4. Confirm the latest legal instrument, not only the spreadsheet.

Official market sources

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Alkyl (C12-22) trimethyl ammonium, bromide and chloride e.g. steartrimonium chloride” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search exact identity across Schedules 4–8.
  3. Apply use, concentration and warning conditions.
  4. Check hazardous-substance classification and Group Standard scope.
  5. Confirm the latest legal instrument, not only the spreadsheet.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This identity appears on a market positive list for the list function represented by the source record. Confirm that the intended function and product use fall within the list scope and every stated condition.

Positive-list presence is purpose-specific and is not blanket approval for every cosmetic use. The searchable spreadsheet is an aid; the legal Group Standard and incorporated notices remain authoritative.

The record cites Schedule 7, reference 44, source row 118, source version effective-2026-01-01. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
