Ethoxylated surfactants detergent range alcohols

Chem. Descrip. surfactant blend of detergent range alcohols ethoxylate (15-40%), sodium dodecylbenzene solfonate (7-13%), ethanol (1-5%), sodium carbonate (1-5%) and formaldehyde (< 0.04%)... 

Based on the surface property data discussed earlier, methyl ester ethoxylates would be expected to perform similarly to alcohol ethoxylates, which is indeed the case. As shown in Fig. 13, methyl ester ethoxylates are comparable to alcohol ethoxylates, as well as other commonly used surfactants (see Table 1), in their ability to remove soil from fabric. Compositional variables affect the performance of methyl ester ethoxylates and alcohol ethoxylates. Lauryl range and tallow range methyl ester ethoxylates provide the best detergency, while optimal ethylene oxide content appears to depend on soil/ cloth-type (Fig. 14). Interaction with other surfactants also affects detergency performance. As shown in Fig. 15, methyl ester ethoxylates act synergistically with alcohol ethoxylates, while the opposite can be observed with alcohol sulfate and alcohol ether sulfate. 

Linear primary alcohols and alpha olefins in the C6-C 8 range have enjoyed remarkable growth in the last three decades. As esters, the C6—C,0 alcohols are used for plasticizing PVC. In the C 2-C]g range, the alcohols are used to make readily biodegradable surfactants of various types such as ethoxylates (nonionic), alcohol sulfates, and sulfates of ethoxylates (anionic). Alpha olefins are used as polyethylene comonomer (33%) and as raw materials for detergent alcohols (22%), oxo alcohols (10%), and lubricants and lube oil additives (18%). 

Applications. Applications of ethoxylated alcohols are munerous in industrial as well as in household products. They are generally excellent detergents and often present beneficial associations with ionic surfactants this fact is ascribed to its opposite sensitivities to temperature, which exert on each other a kind of compensatory effect, thereby permitting an optimum performance within the usage temperature range.
