Problems solved by technology

However, depending on the application, there may be restrictions that cannot be applied due to adverse effects on performance such as foaming properties. Moreover, the fluidity at low temperatures deteriorates, and it is necessary to heat up when mixing detergents. Therefore, , not very satisfactory
[0003] In addition, JP-A-10-17898 or the method of WO91 / 04313 describe the effect of improving the fluidity at around room temperature (20°C) to 70°C, but there is no description of the flowability at around low temperature (5°C). improvement
[0004] As mentioned above, high concentration of polyoxyethylene alkyl ether sulfate or alkyl sulfate has poor fluidity at high viscosity
This leads to poor handling, and there is a problem of gelation when diluting high-concentration substances and using them

Embodiment 1～26、 comparative example 1～12

[0038] Prepare the surfactant compositions shown in Tables 1 to 3 according to conventional methods, and use the following method to determine the viscosity and fluidity of the surfactant at 30°C and 5°C, and the viscosity and fluidity of the aqueous solution of 15% by weight of the component (A). Foaming properties were evaluated.

[0039] In addition, when the component (A) of the surfactant composition of Examples 1-26 was diluted to 15% by weight, gel was hardly generated in the state, and it could be diluted easily (within 5 minutes) at room temperature. On the other hand, when the component (A) of the surfactant compositions of Comparative Examples 1 to 7 and 10 was diluted to 15% by weight, the state was gelled, and it took a long time (about 1 hour) to dilute at room temperature. . When the component (A) of the surfactant compositions of Comparative Examples 8, 9 and 11 was diluted to 15% by weight, some gels were formed in the state, and it took some time (15 to 30 m...

Abstract

Provided is a surfactant composition useful for the preparation of a skin detergent or hair detergent which composition exhibits, in spite of containing a polyoxyethylene alkyl ether sulfate or alkyl sulfate salt in a high concentration, good fluidity over a wide temperature range, does not cause a viscosity increase or gelation during dilution, and can maintain the intrinsic performance of the surfactant. A surfactant composition comprising the following components (A), (B) and (C): (A) a polyoxyethylene alkyl ether sulfate or alkyl sulfate represented by the following formula (1): R 1 O(CH 2 CH 2 O) n SO 3 M (1) wherein, R 1 represents a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, 'n', which is the average number of moles added, is a number of from 0 to 5, and M represents an alkali metal atom, an alkanolamine or ammonium; (B) one or more glyceryl ether or diglyceryl ether having an alkyl or alkenyl group having 4 to 24 carbon atoms, and (C) a water-soluble salt, wherein the content of Component (A) is not less than 40 wt.%.

Description

technical field [0001] The present invention relates to a polyoxyethylene alkyl ether sulfate or alkyl sulfate that has good fluidity in a wide range of temperatures even if it contains a high concentration of polyoxyethylene alkyl ether sulfate or alkyl sulfate, and does not cause viscosity increase or gelation when diluted Surfactant compositions used for the manufacture of skin cleansers such as shampoos and body washes or hair cleansers without degrading the original performance of the surfactant. Background technique [0002] Commonly used polyoxyethylene alkyl ether sulfates or alkyl sulfates have poor fluidity at high concentrations and are difficult to use. In order to make it easy to handle, it is operated at a concentration of 30% by weight or less or in a region where the viscosity is extremely low. Therefore, depending on the application, various attempts have been made to increase the concentration and lower the viscosity by adding a third component (viscosity ...
