Embodiment 1 and comparative example 1 and 2

[0061] [Example 1 and Comparative Examples 1 and 2] Preparation of W / O / W Multiple Emulsion Composition

[0062] A W / O / W multiple emulsion composition was prepared according to the composition (unit: wt %) shown in Table 1 below. A W / O emulsion composition and an O / W emulsion composition are prepared separately, and then the W / O emulsion composition and the O / W emulsion composition are mixed and emulsified, thereby preparing a W / O / W multiple emulsion composition. In the present examples and comparative examples, the amount of surfactant used was less than the amount of surfactant usually used to form stable formulations, and the experiments were conducted under conditions that accelerated the decrease in stability.

Embodiment 2 and comparative example 3 to 5

[0065] [Example 2 and Comparative Examples 3 to 5] Preparation of W / O / W Multiple Emulsion Composition

[0066] A W / O / W multiple emulsion composition was prepared according to the composition (unit: wt %) shown in Table 2 below. A W / O emulsion composition and an O / W emulsion composition are prepared separately, and then the W / O emulsion composition and the O / W emulsion composition are mixed and emulsified, thereby preparing a W / O / W multiple emulsion composition. In the present examples and comparative examples, the amount of surfactant used was smaller than the amount of surfactant usually used to form a stable formulation, and the experiment was carried out under the condition that the decrease in stability was accelerated.

Embodiment 3 and comparative example 6 to 8

[0069] [Example 3 and Comparative Examples 6 to 8] Preparation of O / W / O Multiple Emulsion Composition

[0070] O / W / O multiple emulsion compositions were prepared according to the composition (unit: wt %) shown in Table 3 below. An O / W emulsion composition and a W / O emulsion composition are prepared separately, and then the O / W emulsion composition and the W / O emulsion composition are mixed and emulsified, thereby preparing an O / W / O multiple emulsion composition. In the present examples and comparative examples, the amount of surfactant used was smaller than the amount of surfactant usually used to form a stable formulation, and the experiment was carried out under the condition that the decrease in stability was accelerated.

Abstract

The subject matter of the present specification relates to a multiple emulsion composition comprising three or more phases, wherein two adjacent phases have opposite charges. In the composition, an interface is stabilized by the interaction between charges caused by the opposite charges of adjacent phases, and thus an aggregation, fusion, or creaming phenomenon of emulsion particles can be prevented in the multiple emulsion composition.

Description

technical field [0001] This specification describes multiple emulsion compositions having improved stability. Background technique [0002] Emulsion cosmetic preparations can impart moisturizing ability to the skin and a smooth feeling in use, and examples thereof may include general emulsion types such as oil-in-water (O / W) and water-in-oil (W / O) types and multiple emulsion types containing multiple phases. [0003] A multiple emulsion type emulsion composition is an emulsion composition having multiple phases comprising three or more phases, such as a water-in-oil-in-water (W / O / W) phase comprising an outer aqueous phase, an oil phase, and an inner aqueous phase. type emulsion composition, and an oil-in-water-in-oil (O / W / O) type emulsion composition comprising an outer oil phase, a water phase and an inner oil phase. Compared with general emulsion compositions, multiple emulsion compositions may cause aggregation, fusion, phase inversion or creaming of emulsion particles. ...
