1-Hydroxy-3-nitro-4-(3-hydroxypropylamino)benzene (see note 17): EU cosmetics regulatory profile

Technical answer in context

1-Hydroxy-3-nitro-4-(3-hydroxypropylamino)benzene (see note 17) appears in the captured CosIng dataset as a regulated substance record. The snapshot does not provide a chemical description. The record contains one or more regulatory-review signals—annex III, maximum concentration, conditions or warning wording, SCCS material—so a formula decision should be checked against the current consolidated annex text and the exact product conditions.

Identity and traceability

Identity is the first control because commercially supplied materials can differ by composition, grade, salt, hydrate, particle form or impurity profile. The table below reproduces the identifiers available in this specific source record; a dash or blank is not silently converted into a positive identification.

The safest match is multi-field: compare the supplier specification against the recorded name, CAS/EC identifiers where present, and compositional description. A name-only match is weak evidence for mixtures, botanicals, polymers and materials with variable composition.

Recorded cosmetic functions and peer evidence

Cosmetic functions describe the technical role associated with an ingredient in the inventory. They help frame intended use and documentation questions, but do not replace a safety assessment or determine whether a claim is legally acceptable.

HAIR DYEING

Imparting color to hair. Hair dyeing preparations may be temporary, semi-permanent, permanent, depending on the length of time the colorant remains on the hair. This is a database classification of cosmetic function, not proof that every grade, concentration or finished-product use is suitable.

Within the captured Cruxi analysis set, 196 certified records share this function and 173 of those records carry an annex, restriction, concentration, condition or SCCS signal. That comparison is a prioritisation aid: it does not transfer restrictions from one substance to another.

Annex, restriction and use-condition signals

Read these fields together. A maximum percentage without its product category, use condition or warning can be misleading; an annex reference can change through amendments; and an inventory ingredient may be linked to an identified regulated substance. Where the record is incomplete, use the consolidated regulation and the supplier’s substance identity to close the gap.

SCCS, classification and horizontal-regulation signals

The Scientific Committee on Consumer Safety (SCCS), classification information and other-regulation fields can change the scope of a review. An opinion may concern a particular use pattern or concentration rather than every use of the substance. Horizontal legislation can also matter independently of the cosmetics annexes.

Classification signal

The captured classification field is empty. That absence is not a finding that the material has no hazards or classification obligations.

What the dataset analysis adds

This page is not a copy of one database row. The offline build compared the record with a frozen cohort of 12,358 unique CosIng records. In that cohort, 3,029 records carried at least one annex, restriction, maximum-concentration, condition or SCCS signal. The analysis uses those signals to prioritise review effort; it never treats a cohort rate as a legal rule.

1-Hydroxy-3-nitro-4-(3-hydroxypropylamino)benzene (see note 17) shares its primary recorded function, HAIR DYEING, with 196 records in the captured cohort. Shared function supports comparison of documentation questions, but it does not make the substances toxicologically or legally interchangeable.

The recorded annex group contains 382 captured records. Compare reference number, product scope and conditions within that group before assuming two entries are interchangeable.

Formula-compliance review workflow

1. Resolve identity. Reconcile the supplier INCI, composition and CAS/EC identifiers with this record. Record ambiguities instead of choosing the closest-looking name.
2. Open the current legal text. If an annex or reference is shown, check the consolidated Regulation (EC) No 1223/2009 entry, amendments and any effective dates.
3. Map the actual use. Document finished-product category, leave-on/rinse-off status, target users, body area, exposure route and intended concentration.
4. Carry every condition forward. Capture concentration limits, warning wording, purity criteria, prohibited combinations and professional-use qualifications in the formula specification.
5. Review scientific context. Read the scope and assumptions of any SCCS opinion and compare them with the grade and exposure scenario under assessment.
6. Check horizontal obligations. Consider classification, REACH/CLP or other recorded legislation where relevant; cosmetics compliance does not cancel those duties.
7. Document the decision. Keep the source version, access date, supplier evidence, calculations and assessor rationale in the product information file.

Technical questions teams ask

Does a CosIng entry mean 1-Hydroxy-3-nitro-4-(3-hydroxypropylamino)benzene (see note 17) is approved?

No. CosIng expressly describes itself as informative. Authorisation or restriction depends on the binding regulation and its annexes, applied to the correctly identified substance and use.

Can the recorded function justify a finished-product claim?

No. The function field helps describe an ingredient’s cosmetic role. Finished-product claims still need suitable substantiation and must be assessed in the context of the actual formulation and presentation.

What does a blank concentration or restriction field mean?

It means this captured record does not provide that value in the field. It is not proof of unlimited use. Check linked substances, the current annexes, supplier documentation and other applicable law.

How should this profile be cited internally?

Use the CosIng record ID and source snapshot shown below, then retain the current official record and consolidated legal entry used for the final decision. The Cruxi analysis is a research aid, not the primary legal citation.

Coverage limitation: EU Search limits an unpartitioned result window to 10,000 records. This snapshot contains that deterministic inventory slice plus the complete substance partition; downstream pages disclose the source snapshot and do not claim full-inventory coverage. Data may be amended after the retrieval date. Always verify a final decision against current official sources.
