Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 946-882-9 | CAS number: -
Particle size distribution (Granulometry)
Administrative data
- Endpoint:
- particle size distribution (granulometry)
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is marketed or used in a non solid or granular form
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 04/05/2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Scope:
This procedure is used to qualify the clarity or appearance of solid and liquid raw materials and finished products.
Apparatus:
Whatman #4 filter paper or equivalent (size will depend upon funnel if vacuum filtering)
Ultrasonic bath
Forced fan oven or Heat-Lamp
Reagents:
Acetone (reagent grade)
Procedure:
1. Remove any air bubbles by heating for 1-2 minutes or sonicating. Clean the outside of the jar with acetone.
2. Inspect the entire sample (some particulates can float or settle with time). Gently mix the sample, taking note of any “swirls” of material at the bottom.
3. If doubt persists, filter a portion of the sample and take note of any discoloration or particles on the paper. Another option is to peer through the sample when the jar is placed over a document. The writing should NOT appear fuzzy. - GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- liquid
- Key result
- Form:
- liquid: viscous
- Colour:
- Clear
Pale to yellow color - Substance type:
- organic
- Conclusions:
- The substance is a pale to yellow viscous liquid at 20°C and 1013 hPa.
- Executive summary:
The substance is a pale to yellow viscous liquid at 20°C and 1013 hPa.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
