Abstract
A non-ionic surfactant detergent formulation comprising a detergent and additives to improve the properties of the detergent and wherein the detergent comprises a non-ionic surfactant, and the additive comprises a zwitterionic surfactant carrying at least one hydrophobic group having a straight or branched aliphatic chain of 5 to 9 carbon atoms and at least one aliphatic substituent carrying an anionic water-solubilizing group.
Claims4
A detergent formulation which contains, by weight:
- 17.4% of the reaction product at 40.degree. C. of 1 mole of 1-hydroxyethyl-2-octylimidazoline, in the presence of sodium methylate as catalyst with 1 mole of methylacrylate and following saponification with an amount of water to give a 50% concentrated solution of the resulting amphoteric surfactant,
- 50.1% water,
- 13.0% of a nonionic surfactant obtained from 2,6,8-trimethylnonanol ethoxylated with 6 moles of ethylene oxide,
- 13.0% of tridecyloxypolyethylene ethanol, and
- 6.5% of coconut diethanolamide.

A detergent formulation which contains by weight:
- 17.0% of the reaction product at 100.degree. C. of 1 mole of 1-hydroxyethyl-2-octylimidazoline with 1 mole of methylacrylate and following saponification with an amount of water to give a 50% concentration of the resulting amphoteric surfactant,

C. of 1 mole of 1-hydroxyethyl-2-octylimidazoline, in the presence of sodium methylate as catalyst with 1 mole of methylacrylate and following saponification with an amount of water to give a 50% concentrated solution of the resulting amphoteric surfactant,
- 12.6% of a nonionic surfactant obtained from nonylphenol ethoxylated with 9 moles of ethylene oxide,
- 12.6% of a nonionic surfactant obtained from nonylphenol ethoxylated with 6 moles of ethylene oxide,
