Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- not specified
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data from a peer-reviewed handbook, accepted as a reliable data source according to Chapter R.7A of REACH Guidance on information requirements and chemical safety assessment, adequate for assessment. Restrictions apply as no experimental details and purity is not specified.
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Not applicable.
- Physical state at 20°C and 1013 hPa:
- solid
- Key result
- Form:
- solid: crystalline
- Colour:
- White
- Odour:
- odourless
- Substance type:
- inorganic
- Conclusions:
- Aluminium sulphate, anhydrous, is solid at ambient temperature.
- Executive summary:
A reference handbook, also cited in a reference database, describes the anhydrous form of the substance as white, lustrous crystals, pieces, granules, or powder, with no odour.
- Endpoint:
- appearance / physical state / colour
- Type of information:
- not specified
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data from a secondary source, accepted as a reliable data source according to Chapter R.7A of REACH Guidance on information requirements and chemical safety assessment, adequate for assessment. Restrictions apply as no experimental details and purity is not specified.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Not applicable.
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- solid: crystalline
- Colour:
- colourless
- Substance type:
- inorganic
- Conclusions:
- Aluminium sulphate, octadecahydrate, is solid at ambient temperature.
- Executive summary:
A reference database provides description of the octadecahydrate form of the substance as a solid, colourless, monoclinic crystals.
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 09 March 2010 to 04 June 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Remarks:
- Description of the substance is provided in an experimental report regarding physico-chemical properties. No guideline is required, and test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- no guideline required
- Specific details on test material used for the study:
- Expiry date 18 December 2010 (allocated by NOTOX, 1 year after receipt of the test substance)
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- solid: granular
- Colour:
- white
- Substance type:
- inorganic
- Conclusions:
- The test substance is solid at ambient temperature.
- Executive summary:
An experimental report on physico-chemical properties is available, and describes aluminium sulphate hydrated basic as white granules.
- Endpoint:
- appearance / physical state / colour
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Justification for type of information:
- The test substance is aluminium sulphate basic, of formula Al2 (OH)0.16 (SO4)2.92, and not pure aluminium sulphate Al2 (SO4)3; however, according to the notifier, limited basicity may occur in the technical substance. Therefore, the chemical similarity (only 0.8% OH) is considered sufficient for supporting data on the hydrated form, the reference substance for the REACh registration dossier being the anhydrous form.
- Reason / purpose for cross-reference:
- read-across source
- Physical state at 20°C and 1013 hPa:
- solid
- Executive summary:
From analogue, the 15 -16 H2O hydrated form of the registered substance is expected to be a solid at ambient temperature and pressure.

Description of key information
Aluminium sulphate (anhydrous) is a white, odourless, solid.
Octadecahydrate and other hydrated forms are expected to be solid too (from literature and experiment on analogue).
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
A reliable literature source is provided for the reference substance (anhydrous form), and is considered as key data.
Supporting information on the common hydrated forms 18 and 14 H2O is extrapolated from literature and from description of an analogue in an experimental report.
