AI Technical Summary

Technical Problem

There is room for improvement in the foaming properties and fineness of existing surfactant compositions such as sodium dodecyl hydroxy ether acetate.

Method used

The composition was optimized to improve foaming properties and foam fineness by adding a specific ratio of alkyl hydroxy ether acetic acid (A) and alkyl hydroxy ether acetic acid (B) to the surfactant composition and determining their peak area ratio using liquid chromatography/time-of-flight mass spectrometry (LC-TOF-MS).

Benefits of technology

It significantly improves the foaming properties and foam fineness of surfactant compositions, making it suitable for cleansing agents for skin and hair.

Abstract

The present invention relates to a surfactant composition containing alkyl hydroxy ether acetate (A) represented by the following general formula (1) and alkyl hydroxy ether acetate (B) represented by the following general formula (2), the ratio of the peak area of alkyl hydroxy ether acetate (B) to the peak area of alkyl hydroxy ether acetate (A) measured using a liquid chromatograph / time-of-flight mass spectrometer (LC-TOF-MS) being 0.01% to 10%.R 1 -CH(OH)-CH2-OCH2COOM 1 (1) [In general formula (1), R 1 represents an alkyl group having 8 to 12 carbon atoms, and M 1 represents a hydrogen atom, a sodium atom, a potassium atom, or triethanolammonium.] 2 -CH(OH)-CH2-OCH2COOM 2 (2) [In general formula (2), R 2 represents an alkyl group having 4 to 7 carbon atoms, and M 2 represents a hydrogen atom, a sodium atom, a potassium atom, or triethanolammonium.]
