It is believed that a hydrophilic emulsifier with an HLB exceeding /O must be used as the main emulsifier for W emulsions. The O/W emulsion is generally prepared by dissolving or dispersing the hydrophilic emulsifier in an oil phase, and gradually adding an aqueous phase while stirring. It is also well known that this method produces fine emulsions with the least amount of energy. On the other hand, a method of adding the oil phase without stirring the water phase is D-phase emulsification.

リとしてアンモニア。[Problem to be solved by the invention] The hydrophilic emulsifiers used in conventional O/W emulsions and O/W/O emulsions, whose HLB exceeds /O, deteriorate the quality of products using these emulsions. I was letting it happen. For example, water resistance deteriorates with car wax, floor wax, emulsion paint, etc. It makes food taste bad. Also, do cosmetics have poor moisturizing properties? Naru etc. Therefore, one-soap emulsification is well known as a method for producing an O/W emulsion by minimizing the use of hydrophilic emulsifiers that have such problems. Soap emulsification is a method in which an emulsifier and a fatty acid are dissolved in an oil phase, and an aqueous alkaline solution is added to the solution while stirring well. This method uses oil/
It is said that because soap (hydrophilic surfactant) is produced by fatty acids and alkalis at the water interface, a fine emulsion can be created with less energy. In such systems, the amount of soap relative to the weight of the lipophilic surfactant is often 20% or more. That is, the hydrophilic surfactant (HLB

不安定化するからである。Although it is not particularly limited and can be set to, for example, about 0.99, the preferred weight ratio of (oil phase + emulsifier)/aqueous phase is about 60/4 o or less. This is because if the weight ratio of (oil phase + emulsifier)/aqueous phase exceeds 60,740, the O/W emulsion becomes unstable.

The oil phase consists of 99.9 to 0% by weight (more preferably 90 to 30% by weight). This is because when the O/W emulsion of the present invention is less than 0.1% by weight, the effect of the O/W/O emulsion is often not clear.
On the other hand, if it exceeds 90% by weight, the O/W/O emulsion often cannot exist stably.

からである。The base W/O emulcidin is composed of an aqueous phase dispersed in an oil phase, and the lower limit of the weight of the aqueous phase is not particularly defined, and preferably the weight ratio of the aqueous phase/oil phase is 0.001 to 0. Make it about .9. When the weight ratio of the aqueous phase/oil phase exceeds 0.9, dispersing the O/W emulsion in the aqueous phase of the base W/O emulsine will result in the dispersion of the base W/O emulsion (the O/W/O emulsine of the present invention). This is because the O emulsion) often becomes unstable.
