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.
Claims1
The surfactant detergent formulation which contains, by weight:
- 37.0% of the reaction product at 100.degree. C. of 1 mole of 1-hydroxyethyl-2-octylimidazoline with 1 mole of methacrylate and following saponification with an amount of water to give a 50% concentration of the resulting amphoteric surfactant,
- 27.2% of a nonionic surfactant obtained from nonylphenol ethoxylated with 9 moles of ethylene oxide,
- 27.2% of a nonionic surfactant obtained from nonylphenol ethoxylated with 6 moles of ethylene oxide, and
- 8.6% of coconut diethanolamide.
