Description of key information

Sulfonic acids, petroleum, calcium salts (CAS 61789-86-4) the substance is produced by sulphonation of alpha-olefins, typically mineral oil with suitable substrates to produce the substance subject to registration.  As the mineral oil is a starting material and is essential to stabilise the chemical structure of the substance, it is not possible to remove the mineral oil from the substance.  The substance will not occur in nature but, in the absence of mineral oil, assessment of the chemical structure determines that the chemical species would be a glass-like solid substance.  The physical nature of the substance in mineral oil is, however, a highly viscous liquid.  The mineral oil is not, however, a constituent of the substance.
