MAGNESIUM LOW BASE NUMBER SULPHONATES

摘要

Magnesium low base number (LBN) sulphonates derived from high molecular weight sulphonic acids have low viscosity and are chloride free. The magnesium low base number sulphonates are not skin sensitisers. In their preparation neutralisation of high molecular weight sulphonic acids or partially neutralised soaps of high molecular weight sulphonic acids is completed by the use of a high base number sulphonate in conjunction with a carboxylic acid. The process does not require the use of chloride containing promoters and produces low chloride products.
