Ingredient source facts
PIGMENT RED 172 ALUMINUM LAKE has identifier matches to Annex II 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. The informative CosIng metadata and legal-table references differ; this page does not treat them as interchangeable.
Evidence retrieved 2026-10-06. Source versions and topic-specific limits are listed below.
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.
Recorded identity: 2′,4′,5′,7′-Tetraiodofluorescein, its disodium salt (Acid Red 51; CI 45430) and its aluminium salt (Pigment Red 172 Aluminium lake) when used as a substance in hair dye products
Matching CAS: 12227-78-0 · Matching EC: 235-440-4
Review the exact scope of this Annex II entry: 2′,4′,5′,7′-Tetraiodofluorescein, its disodium salt (Acid Red 51; CI 45430) and its aluminium salt (Pigment Red 172 Aluminium lake) when used as a substance in hair dye products [2]
The consolidated text is a dated reference. Current amendments, corrigenda and applicability dates must be checked. EU evidence does not resolve Great Britain rules.
Known context: EU. Ingredient identity is recorded; concentration, intended use, exposure and current legal conditions still need checking.
| Source fact | Recorded value | What to check |
|---|---|---|
| INCI / recorded name | PIGMENT RED 172 ALUMINUM LAKE [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| Common ingredients glossary name | PIGMENT RED 172 ALUMINUM LAKE [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| CAS identifiers | 12227-78-0 [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| EC identifiers | 235-440-4 [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| Recorded chemical description | Pigment Red 172 Aluminum Lake is an insoluble pigment composed of the aluminum salt of Acid Red 51 extended on an appropriate substrate. It conforms to the formula: [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| Informative CosIng functions | COLORANT, HAIR DYEING [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| Chemical name | 2-(3,6-Dihydroxy-2,4,5,7-tetraiodoxanthen-9-yl)benzoic acid, aluminium salt (CI 45430) [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
| CosIng annex reference | II/1337 (when used as a substance in hair dye products) [1] | Check identity, concentration, exposure and use against the current legal annex and any amendments. |
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.
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.
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.
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.
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.
Read the official document in context. The audit details identify the precise locators and preserved versions used for this page.
