Problems solved by technology

Therefore, as an appearance impression, the greasy image is strong, and it tends to be unacceptable to those who require moisture and transparency.
[0003] On the other hand, it is difficult to mix a large amount of oil-based ingredients in skin external preparations such as lotion and water-based jelly, which usually use the solubilizing properties of surfactants to mix oil-based ingredients.
Therefore, in general, the moisturizing effect and skin care effect of the oily component of external skin preparations with good transparency tend to be lower than those of emulsions, creams, etc. that contain a lot of oily components.

Embodiment 1～ Embodiment 8

[0202] Among the components described in Table 1 below, component C, component D, component E, and ethanol as component F were heated and dissolved at 70° C. for 45 minutes to obtain an aqueous phase composition A.

[0203] Component A, component B, other components of tocopherol and astaxanthin-containing oil (Haematococcus extract, ASTOTS-S, Fujifilm Co., Ltd., containing 20% ​​astaxanthin) listed in the following Table 1 ) was heated at 70° C. for 30 minutes to dissolve, thereby obtaining an oil phase composition A.

[0204] While stirring the obtained water phase composition A, add the obtained oil phase composition A to the water phase composition A, using an ultrasonic homogenizer (model: US-600, Nippon Seiki Seisakusho Co., Ltd.), every 100g. Sonicate for 1 minute to obtain a pre-emulsion.

[0205] Next, the obtained pre-emulsion was subjected to high-pressure emulsification at a pressure of 245 MPa using an ultra-high-pressure emulsification device (model name: Ultima...

Embodiment 9～ Embodiment 13

[0281] [Example 9 to Example 13, Comparative Example 1]

[0282] An emulsified composition was prepared in the same manner as in Example 1 according to the recipe in Table 2 below, and the obtained emulsified composition was evaluated in the same manner as in Example 1. The results are collectively described in Table 2 below. As a comparative example, the formulation and evaluation results of Example 3 are listed in Table 2.

[0283] 【Table 2】

[0284]

[0285] As can be seen from the results in Table 2, the emulsified compositions of Examples 9 to 13, like the emulsified composition of Example 3, have good transparency and are emulsified compositions having practically sufficient gel hardness. From the evaluation results of Example 3 and Examples 9 to 13, it can be seen that when the content of component A is increased, the gel hardness tends to increase.

[0286] On the other hand, in Comparative Example 1 in which the content of component A was 15% or less, the hardne...

Embodiment 14～ Embodiment 17、 comparative example 2～ comparative example 6

[0288] An emulsified composition was prepared in the same manner as in Example 1 according to the recipe in Table 3 below, and the obtained emulsified composition was evaluated in the same manner as in Example 1. The results are collectively described in Table 3 below. As a comparative example, the formula and evaluation results of Example 3 are described in Table 3.

[0289] 【table 3】

[0290]

[0291] As can be seen from the results in Table 3, the emulsified compositions of Examples 14 to 17, like the emulsified composition of Example 3, have good transparency and are emulsified compositions having practically sufficient gel hardness. From the evaluation results of Example 3 and Examples 14 to 17, it was found that by using fatty acid (poly)glycerides as the B component, both transparency and gel hardness were further improved.

[0292] On the other hand, when a fatty acid (poly)glyceride (comparative component) with an HLB exceeding 7 was used or a surfactant (compara...

Abstract

An oil-in-water gel emulsion composition characterized in that it comprises the following component A to component E: (component A) at least one liquid-state oil selected from a hydrocarbon oil, an aliphatic ester or a silicone oil, wherein a content of the liquid-state oil with respect to a total amount of the oil-in-water gel emulsion composition is 15% by mass or higher; (component B) at least one non-ionic emulsifying agent having an HLB of 7 or lower selected from a (poly)glyceryl fatty acid or a POE hydrogenated castor oil; (component C) a sucrose fatty acid ester; (component D) an ionic surfactant having a glutamic acid as a hydrophilic group; and (component E) water, wherein a total content ratio of component B, component C, and component D, with respect to component A, is from 0.1 to 0.5 by mass.

Description

technical field [0001] The present invention relates to a gel-like oil-in-water emulsion composition, a skin external preparation, and a method for producing the oil-in-water emulsion composition. Background technique [0002] Generally, oily components are blended in skin external preparations such as cosmetics for the purpose of moisturizing the skin. External skin preparations such as lotions and creams that contain a large amount of oily ingredients appear white and lack transparency. Therefore, as an external impression, the greasy image is strong, and it tends to be unacceptable to those who require moisture and transparency. [0003] On the other hand, since skin external preparations such as lotion and water-based jelly have good transparency, oil-based ingredients are usually blended using the solubilizing properties of surfactants, so it is difficult to blend a large amount of oil-based ingredients. Therefore, in general, the moisturizing effect and skin care eff...
