or tri glycerides ethoxylated fatty acids etc however ethoxylated alcohols and phenols are the preferred co surfactants ethoxylated alcohols have been used in past as a stabilising emulsifying additives for making water containing fuel compositions for example a u s pat no 6 080 716 of 2000 describes a surfactant which is made by reaction of aliphatic alcohol with ethylene oxide the non ionic ethoxylated surfactant as emulsifying additives are prepared from reaction of aliphatic alcohol with ethylene oxide and are also available commercially in one embodiment the cosurfactant is ethoxylated linear alcohol nonionic type with varying alcohol chain and ethoxylation content these are available commercially as tomah products under the name u201c tomadol u201d these have the general chemical representation as ro ch 2 ch 2 o nh where r is mostly linear alkyl chain and n may vary from 2 5 to about 12 preferably from 2 5 to 7 these ethoxylates are generally in the molecular weight range of 280 to 590 and the ethylene content wt varies from 35 to 70 the advantage of using u201c tomodols u201d include the preferred range of hlb values of 4 to 12 and acceptable flash points which are in the range of 140 248 u00b0 c the lower u201c tomodols u201d are liquids at ambient temperature having.
