Ingredient source facts

1,4-Benzenediamine, 2-(methoxymethyl) 1,4-Benzenediamine, 2-(methoxymethyl)-, sulfate: EU cosmetic annex conditions and formula evidence

1,4-Benzenediamine, 2-(methoxymethyl) 1,4-Benzenediamine, 2-(methoxymethyl)-, sulfate has identifier matches to Annex III in the acquired 18 May 2026 EU Cosmetics Regulation text. The table distinguishes the substance identity, product-use conditions and recorded limits. Confirm the exact substance/group scope, formula concentration and intended use before applying an entry. This does not certify formula safety or settle Great Britain requirements.

Evidence retrieved 2026-10-06. Source versions and topic-specific limits are listed below.

Exact legal-entry matches and product-use conditions

Exact checksum-valid CAS and/or exact EC identifier in preserved legal identity cells. Group and substance scope are still conditional.

Each line below retains its own concentration basis, conditions and warnings. Blank source cells mean no condition was recorded in that cell; they do not establish unrestricted use.

Annex III · Entry 292

Recorded identity: 1,4-Benzenediamine, 2-(methoxymethyl) 1,4-Benzenediamine, 2-(methoxymethyl)-, sulfate

The consolidated text is a dated reference. Current amendments, corrigenda and applicability dates must be checked. EU evidence does not resolve Great Britain rules.

Resolve the entry against your actual formula

Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.

  1. Does the supplied material fall within these exact entries?

    Put your supplier CAS/EC, substance composition, salt/group membership, purity, physical form and intended function beside each matched entry. A matching identifier does not resolve every group or impurity condition.

    Useful evidence: Supplier specification, composition and certificates of analysis; the exact annex rows above.

  2. Which row governs the finished-product use?

    Compare the finished-product concentration, body site, rinse-off/leave-on use, consumer/professional setting and any exposure restrictions with each row. Preserve the units and calculation basis; do not transfer a limit from a different product-use row.

    Useful evidence: Quantitative formula and use instructions; a row-by-row condition and warning worksheet.

  3. Is a prohibition or trace question involved?

    For Annex II matches, review Article 14 before formulation decisions. Article 17 concerns a separate, conditional non-intended trace situation; it does not grant blanket permission to intentionally add a prohibited substance. Record origin and technical-avoidability evidence for specialist review.

    Useful evidence: Ingredient/impurity origin, manufacturing controls, trace quantities and the cited Article 17 text.

  4. What must reach the safety assessor and Responsible Person?

    Send the reconciled identity, condition table, exposure facts, supplier evidence and unresolved amendment/date questions. Agree formula, assessment and PIF responsibilities before notification or manufacturing handoff.

    Useful evidence: A dated formula-evidence matrix, supplier data, exposure description and document ownership list.
