Some physicochemical properties of chlorinated paraffins (from Nielsen and Ladefoged, 2013; EU‐RAR, 2000, 2005, 2011)

	SCCPs	MCCPs	LCCPs
Description	Clear to yellowish mobile to highly viscous oily liquid	Liquid	Liquid or solida
Additivesb	Epoxidised vegetable oil, glycidyl ether, organophosphorous compounds
Boiling point	> 200°Cc
Solubility	Practically insoluble in: Water (< 0.5 mg/L at 20°C), lower alcohols, glycerol and glycols Soluble in: chlorinated solvents, aromatic hydrocarbons, ketones, esters, ethers, mineral oil
Vapour pressure	Chlorine content 50%: 1.6 × 10−4 mmHg (0.0213 Pa) (at 40°C)	Chlorine content 45%: 1.7 × 10−5 mmHg (0.0023 Pa) (at 40°C) Chlorine content 52%: 1.0 × 10−6–2.0 × 10−6 mmHg (0.00013–0.00027 Pa) (at 20°C)	–
Log Po/w	Chlorine content 49%: 4.39–6.93 Chlorine content 71%: 5.68–8.69	Chlorine content 45%: 5.52–8.21 Chlorine content 52%: 5.47–8.01	Chlorine content 42%: 9.29–> 12.83 Chlorine content 48%: 8.69–12.83

SCCPs: short‐chain chlorinated paraffins; MCCPs: medium‐chain chlorinated paraffins; LCCPs: long‐chain chlorinated paraffins.

^aDepending on the carbon chain length and chlorine content.

^bAs stabilisers, to improve thermal and photo stability.

^cAround 200°C decomposition with release of hydrogen chloride occurs.
