Example Embodiment
[0023] Example 1:
[0024] Add 0.1 mol coconut oil and 35.1 g PEG8000 to a reaction flask equipped with a stirrer, thermometer, water separator and reflux condenser. After heating to 100 ℃, stir and melt, add 0.3 mol sodium lysine, heat to 150 ℃, and react at a constant temperature. In 10 hours, 1.6% sodium caprylyl lysine content, 2.1% sodium decanoyl lysine content, 32.2% sodium lauroyl lysine content, 12.8% sodium myristoyl lysine content, palmitoyl lysine content Sodium content 7.1%, sodium linoleyl lysine content 1.5%, sodium oleoyl lysine content 11.6%, sodium stearoyl lysine content 1.6%, sodium lysine content 0.4%, sodium fatty acid content 0.9% , PEG8000 content 22.6%, glycerol content 5.6% sodium cocoyl lysine surfactant composition.
Example Embodiment
[0025] Example 2:
[0026] Add 0.1 mol palm kernel oil and 35.5 g PEG8000 into a reaction flask equipped with stirring, thermometer, water separator, and reflux condenser, heat up to 100 ℃, stir and melt, add 0.3 mol sodium lysine, heat to 160 ℃, constant temperature After 8 hours of reaction, 0.1% sodium caproyl lysine content, 1.6% sodium octanoyl lysine content, 2.1% sodium decanoyl lysine content, 31.1% sodium lauroyl lysine content, and myristoyl lysine content were obtained. Sodium content 12.7%, sodium palmitoyl lysine content 7.1%, sodium linoleoyl lysine content 1.6%, sodium oleoyl lysine content 12.3%, sodium stearoyl lysine content 1.6%, arachidic acid A palm kernel oleoyl lysine sodium surfactant composition with a sodium lysine content of 0.1%, a sodium lysine content of 0.4%, a fatty acid sodium content of 1.0%, a PEG8000 content of 22.6%, and a glycerol content of 5.7%.
Example Embodiment
[0027] Example 3:
[0028] Add 0.1 mol olive oil and 41.7g PEG8000 into a reaction flask equipped with a stirrer, thermometer, water separator, and reflux condenser. After heating to 100℃, stir and melt, add 0.3 mol sodium lysine, heat to 160℃, and react at a constant temperature. In 8 hours, 7.3% sodium palmitoyl lysine content, 0.5% sodium palmitoyl lysine content, 60.1% sodium oleoyl lysine content, 2.4% sodium stearoyl lysine content, and arachidoyl lysine An olive oil acyl lysine sodium surfactant composition with a sodium content of 0.2%, a sodium lysine content of 0.5%, a fatty acid sodium content of 1.0%, a PEG8000 content of 22.5%, and a glycerol content of 5.5%.
