が、前記の全ての条件を満たすことはできない。As the fatty acid constituting the fatty acid monoethanolamide, coconut oil fatty acid obtained from natural coconut oil is most often used. However, coconut oil fatty acid monoethanolamide is excellent in foamability, detergency, and low temperature stability, but it is not always sufficient in thickening, and it may be difficult to obtain a product having a desired viscosity. Therefore, among those skilled in the art, the carbon number is 12, 14, 1
Although fatty acids mainly containing 6,18 are obtained and monoethanolamide from these fractionated fatty acids is used, all the above conditions cannot be satisfied.

The fatty acid monoethanolamide mainly containing the above fatty acids has a strong thickening property, but the foaming power, detergency and low temperature stability are deteriorated.

に至った。[Means for Solving the Problems] In order to solve the above problems, as a result of intensive studies by the present inventors, it was found that only fatty acid monoethanolamide having a fatty acid composition within a specific range is effective in solving the above problems. The present invention has been solved.

That is, when the fatty acid having less than 12 carbon atoms exceeds 15%, the thickening property becomes poor. Carbon number 1
If the fatty acid of 2 is less than 45%, the viscosity increase is poor, and if it exceeds 55%, the low temperature stability is deteriorated. If the saturated fatty acid having 14 carbon atoms is less than 12%, the thickening property will be poor, and if it exceeds 17%, the low temperature stability will be poor. If the unsaturated fatty acid having 18 carbon atoms is less than 12%, the thickening property is poor, and if it is 17% or more, the low temperature stability is poor.
