Detailed description of the invention

A silicone compound is a water-insoluble compound, and the silicone compound, when applied to an aqueous composition such as a finishing product used in household laundry, is emulsified with a surfactant or the like and It is incorporated into the aqueous composition. The aqueous composition is often added in a rinse phase in a wash stage, diluted with excess water and brought into contact with fiber products such as clothing. However, when the silicone compound emulsified with a surfactant or the like is diluted with an excess of water, the ability of the surfactant to emulsify the silicone compound decreases significantly destroying the emulsion, so that the silicone compound cannot be present in stable way. Therefore, the silicone compound cannot be adsorbed effectively on the fibers, and much of the silicone compound in the aqueous composition can be discharged into the wastewater or adhered to a wash bath, thus making it difficult to provide the effect of the compound of Sufficiently silicone fiber products.

Then, components (d1) and (d2) are added thereto if necessary under stirring and left under stirring. After that, component (b) is slowly added. When component (b) is in a non-fluidized or solid state at usual temperatures, it is desirably added with heating at a temperature higher than the melting point or fluidization point. In this case, the solution (F) is also desirably heated to a temperature higher than the melting point or fluidization point of the component (b). After that, the resulting combination is further stirred, heated to 60 ° C or to a temperature higher than the melting point or fluidization point of component (b) and then stirred to provide a composition. The composition is left at the same temperature or cooled to about 40 ° C, and the rest of the component (c) is slowly added to the resulting composition obtained by the above method and then stirred. If necessary, the pH is regulated, and the temperature of the combination is reduced to usual temperatures to provide the oil-in-water emulsion of the present invention.
