Embodiment 1

[0043] Mix 22.5 parts by weight of aliphatic alcohol [SASOL company, Nacol 18-98] with 18 carbon atoms and 7.5 parts by weight of calcium carbonate [Shiraishi Industry Co., Ltd., Brilliant-1500] as water-insoluble hydrophilic inorganic fine particles , heating and melting the aliphatic alcohol with 18 carbon atoms. Then, the melt was stirred at 73° C. with a turbine blade at a peripheral speed of 5.2 m / s, while 73° C. hot water was dropped thereon. Stirring was temporarily stopped when a high-viscosity gel-like mixture was obtained, and then 69.94 parts by weight of hot water at 73° C. was added in total, and then stirring was restarted. 0.06 parts by weight of Welangam (product name) (Sanjing Co., Ltd., KIC376) was added to the resulting emulsified dispersion liquid, and cooled to obtain an oil-in-water emulsion composition. The results of the time-lapse thickening test of the sample composition of Example 1 are shown in the following "Table 1".

Abstract

The present invention provides an oil-in-water emulsion composition having excellent storage stability without being restricted by blending and without thickening or solidification during storage. An oil-in-water emulsion composition and a method for producing the composition are provided, wherein the oil-in-water emulsion composition is an oil phase component containing a higher alcohol with 12 to 30 carbon atoms and a poorly water-soluble An oil-in-water emulsion composition of hydrophilic inorganic fine particles according to the present invention, wherein the fine particles of the oil phase component are dispersed in a state covered with the hydrophilic inorganic fine particles.

Description

technical field [0001] The present invention relates to a technology related to oil-in-water emulsion compositions. More specifically, it relates to a novel oil-in-water emulsion composition without adding an emulsifier and a method for producing the composition. Background technique [0002] Currently, oil-in-water (Oil in Water) emulsion compositions are widely used as foam inhibitors (antifoaming agents) in various manufacturing processes or processing processes mainly in papermaking processes, or in wastewater treatment processes. Such a composition is usually formed by adding an emulsifier and water to the oil phase components, and dispersing the oil phase components in water. [0003] Among the antifoaming agents composed of this oil-in-water emulsion composition, a composition containing a higher alcohol component is known (for example, refer to Patent Document 1). However, since such an antifoaming agent thickens violently during storage and solidifies into a cream...
