Measured values for Acetic acid, and where each one comes from
32 measured values for 12 properties, read from 4 public databases. On 3 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point

- Miscible
- NIOSH Pocket Guide
Partition coefficient (log Kow)
1 record
Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.
- log Kow = -0.17

Viscosity
1 record
Governs how far a spill spreads and how fast it soaks into a surface or a sorbent.
- 1.056 mPa-s at 25 °C
- Hazardous Substances Data Bank (HSDB)
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.

Odour
2 records, each a different case
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- Sour, vinegar-like odor

These are the public records read for Acetic acid, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
