[preparation of liquid washing agent]
(embodiment 1～38,, comparative example 1～6)
According to the composition shown in table 1～5 (formulated component, amount), by following sequential system for each routine liquid washing agent.
In 500mL beaker, put into purified water, (A) composition and stirrer, with agitator (day is stretched physics and chemistry manufacture by magnetic stirring apparatus SW-RS077 Co., Ltd.), be stirred to evenly.Then, respectively by (B) composition, (C) composition or (C ') composition and (D) composition limit confirm uniform dissolution, limit adds.Then, add common component, be stirred to evenly.In addition, while allocating (E) composition or LAS into, add together with (A) composition.
The preparation of such liquid washing agent need not be controlled temperature especially, at room temperature carries out.About stirring velocity, suitably set rotating speed so that stirrer can rotate well.
[evaluation of liquid washing agent]
Respectively storage stability under the viscosimetric analysis of each routine liquid washing agent and cold condition is evaluated.
(viscosimetric analysis)
Filling liquid washing composition 50g in the bottle of capacity 50mL (SV-50A says electric physics and chemistry Xiao Zi Co., Ltd. and manufactures), in being set as the thermostatic bath (manufactures of T22LA thomas company) of 30 ℃, preservation is 2 hours.Then, with Brookfield viscometer (viscometer TV-20, Tokyo Keiki Inc. manufactures), measure the viscosity of liquid washing agent.
Condition determination is set as rotating speed 30rpm, rotor No.2, rotational time 30 seconds, 30 ℃ of temperature, the viscosity of measuring is 100～1000mPas, and (this considers to obtain from the following aspects: the preparation of the not enough 100mPas of viscosity for qualified, because viscosity is low, so to the easy variation such as the coating of washing clothes, anelasticity, and be difficult to obtain sufficient clearing power; Viscosity surpasses the preparation of 1000mPas, because viscosity is too high, so the easy variation of discharge from container).(storage stability under cold condition)
Filling liquid washing composition 50g in the bottle (SV-50A, a day physics and chemistry Xiao Zi Co., Ltd. manufactures) of capacity 50mL preserves 1 angel's liquid washing agent fully charge under the environment of-5 ℃.Then, under the environment of 5 ℃, preserve 1 day, naturally thaw.
Repeating such operation (preserves under the environment of 5 ℃ after 1 day, preserves 1 day :-5 ℃ under the environment of 5 ℃
5 ℃) after 5 times and after 10 times, the outward appearance of observing liquid washing agent under the environment of 5 ℃.Then, according to following metewand, the storage stability under cold condition is evaluated.
In addition, be somebody's turn to do-5 ℃
the repetitive operation of 5 ℃ is the appreciation condition of supposing especially the change of the temperature on daytime in winter.
The conduct of < < metewand > > Crystal is defective.
Clear: can not see separating out of muddiness or crystallization completely.
Cloudy: can see muddiness.
Sedimentation: can see separation.
Crystal: can see separating out of crystal.

From the result shown in table 1～5, can know, the liquid washing agent of applicable embodiments of the invention is used inorganic salt can seek to increase the excellent storage stability under viscosity and cold condition.
