Additional information

Squalane is the saturated form of squalene. It does not contain any double bonds in its chemical structure and therefore is very stable against heat and oxidation and not subject to hydrolysis.

The ready biodegradation of the squalane was determined by the carbon dioxide evolution test method (OCDE guideline 301B). The results indicated that the activated sludge inoculum was active, degrading the canola oil reference 99.9%. The average cumulative percent biodegradation for squalane was 64.7%. However, squalane may be considered inherently biodegradable because it reached 60% of TCO2, though not within a 10 -days window of reaching 10% TCO2.

Remark : Direct exposure to soil unlikely to occur.
