Description

The present invention relates to a W/O/W emulsion composition.

In the field of cosmetics, creams can be thickened by using thickeners such as polymers, forming α-gels using surfactants and higher alcohols, or by increasing the internal phase ratio.

On the other hand, the addition of polymeric thickeners can lead to stickiness and other issues that can make the product less usable, and the formation of α-gel in the aqueous phase requires a relatively large amount of surfactant. Furthermore, increasing the internal phase (oil phase) ratio in an O/W emulsion composition can result in a loss of freshness due to the increased amount of oil.

In contrast, a W/O/W emulsion composition such as that shown in Patent Document 1, which can be used as a cream, has a small amount of inner aqueous phase during production, and after preparing the W/O/W emulsion composition, water is transferred from the outer aqueous phase to the inner aqueous phase due to the osmotic pressure difference. As a result, a high inner phase (oil phase + inner aqueous phase) ratio can be obtained with a relatively small amount of oil phase, resulting in a fresh feeling despite the high viscosity, and a unique phase inversion sensation associated with the release of the inner aqueous phase upon application to the skin.

In addition, by adding a drug or other substance to the inner aqueous phase of a W/O/W emulsion composition, the drug is covered by the oil phase and the outer aqueous phase, improving stability such as oxidation resistance.

On the other hand, osmotic pressure-adjusting W/O/W emulsion compositions have the problem of being highly selective about the oil phase components, resulting in low flexibility in formulation. For example, when silicone oil is blended in large amounts, the stability of the composition tends to decrease.

The internal aqueous phase in this composition comprises an osmotic pressure regulator, which generates osmotic pressure between the internal aqueous phase and the external aqueous phase, and transfers water from the external aqueous phase to the internal aqueous phase.

The present invention will be specifically described based on the following examples, but the present invention is not limited to these examples. Contents are expressed in mass % unless otherwise specified.

Using four types of osmotic pressure regulators (sodium L-glutamate, sorbitol, maltitol, and trehalose), W/O/W type emulsion compositions as shown in Table 1 below were prepared. The W/O/W type emulsion compositions were obtained by adding an aqueous phase containing an osmotic pressure regulator to an oil phase containing a surfactant, emulsifying the aqueous phase in W/O using a homomixer, and then adding the W/O emulsion to an external aqueous phase and dispersing with a disperser. The viscosity of each sample was measured the next day at a sample temperature of 30°C using a VISCOMETER TVB-15 (manufactured by Toki Sangyo Co., Ltd.), rotor No. 6, and 10 rpm. Next, the change in viscosity of each sample over time was also measured. In addition, the pH of each sample was measured using a pH meter F-53 (manufactured by Horiba, Ltd.), and the particle size of the emulsified particles was measured using a digital microscope RH-2000 (manufactured by Hirox Co., Ltd.). The measurement results are shown in Table 1.

These results show that W/O/W emulsion compositions using trehalose as an osmotic pressure regulator show less viscosity loss when stored at 50°C compared to compositions using other osmotic pressure regulators. Therefore, it was shown that W/O/W emulsion compositions containing trehalose are more stable than W/O/W emulsion compositions containing other osmotic pressure regulators.

Other Formulations Formulation Examples 1 to 3 included in the scope of the W/O/W emulsion composition of the present invention are shown in Tables 2 to 4.
