preparation example Construction
[0106] From the viewpoints of ease of preparation of the liquid detergent, water solubility during use, and the like, the liquid detergent of the present invention preferably contains water as a solvent.
[0107] The lower limit of the mixing amount of water in the liquid detergent relative to the total mass of the liquid detergent is preferably 40% by mass or more, more preferably 45% by mass or more, and even more preferably 50% by mass or more. In addition, as the upper limit, it is preferably 90% by mass or less, more preferably 85% by mass or less, and still more preferably 80% by mass or less. The upper limit and lower limit can be combined arbitrarily. The mixing amount of water in the liquid detergent is, more specifically, preferably 40 to 90% by mass, more preferably 45 to 85% by mass, and still more preferably 50 to 80% by mass relative to the total mass of the liquid detergent.
[0108] If the mixing amount of water is more than the lower limit, the liquid stability of...
Embodiment
[0229] The following examples illustrate the present invention in further detail, but the present invention is not limited by these examples.
[0230]
[0231] According to the composition ratio shown in the table, the liquid detergent of each example was prepared according to the manufacturing method shown below (if there is an unmixed component, the component is not mixed).
[0232] The unit of the mixing amount in the table is "mass %", and any ingredient means the converted amount of the pure ingredient. Regarding the component (e), the upper part indicates the mixing amount as a divalent metal salt (e-1 and e-2 are hydrated salts), and the bracket in the lower part indicates the amount of divalent metal converted. The divalent metal conversion amount for e-1 and e-2 indicates the zinc conversion amount, and the divalent metal conversion amount for e-3 indicates the magnesium conversion amount.
[0233] The liquid detergent of each example was balanced and prepared with water so...
preparation example
[0257] The preparation was performed in the same manner as a-1 except that 349 g of "Lutensol XL40" manufactured by BASF was used instead of "Lutensol XP30" manufactured by BASF.
[0258] a-4: Mono(2-propylheptyl) ether sulfate Na, equivalent to C in the above formula (a1) X H 2X+1 = Propyl, C y H 2y+1 =Pentyl, x+y=8, p=0, q=0, M=sodium.
[0259] [A-4 Preparation example]
[0260] The hexanal is subjected to Guerbet condensation (dimerization) with alkali, and 158 g of 2-propylheptanol thus obtained is put into a 500 mL flask with a stirring device. After nitrogen replacement, the reaction temperature is maintained at 40°C. While slowly dripping liquid sulfuric anhydride (sulfane) 81g. After the dropping was completed, the stirring was continued for 1 hour to obtain the target alkyl ether sulfuric acid. Further, it was neutralized with an aqueous sodium hydroxide solution to obtain a-4.
