New ester-amides containing one or more long chain fatty acyl groupings are described which have antimicrobial activity against several pathogenic microorganisms, and have properties making them useful as antimicrobial agents.
Provided is a liquid composition that places a low burden on the environment and has such properties as to thicken or gelate upon the application of strain. The liquid composition according to the present invention contains components (A), (B), (C), and (D). The component (A) is an N-methyl-N-(2,3-dihydroxypropyl) fatty amide represented by Formula (1). The component (B) is an N-methyl-N-(2-hydroxypropyl) fatty amide ester represented by Formula (2). The component (C) is an oily substance. The component (D) is water. Formulae (1) and (2) are expressed as follows:
There is provided a surfactant composition for detergents, which has its high detergency and foamability within a broad pH region even in the presence of solids. It has its excellent foamability, thickening property, water solubility and stability. The composition contains a component (a) represented by the following formula (I) and at least one component (b) represented by the formulae (II) and (III), in the total amount of 0.1 to 80% by weight, at the ratio of (a)/(b) by weight of from 99.9/0.1 to 70/30.
1
In the formula (I), R
1
CO— is a saturated or unsaturated acyl group which has 6 to 24 carbon atoms and which may have hydroxy group; R
2
is a linear or branched alkyl group having 1 to 3 carbon atoms; and R
3
is a linear or branched alkylene or alkenylene group having 1 to 6 carbon atoms.
2
In the formulae (II) and (III), R
1
CO—, R
2
and R
3
have the same meanings as above and R
4
CO— is a saturated or unsaturated acyl group which has 6 to 24 carbon atoms and which may have a hydroxy group. The composition may also contain a surfactant other than the above-mentioned components (a) and (b).
