[0173] [Method for preparing emulsified composition]

[0174] The emulsified composition can be produced by a production method including a step of mixing an oil-phase composition containing at least solid hydrocarbon, silicone, and a higher alcohol, and a water-phase composition, and emulsifying by a conventional method.

[0175] Water phase compositions preferably contain water, emulsifiers and certain humectants.

[0176] Hereinafter, a preferred preparation method of the emulsified composition will be described in detail.

[0177] For example, a) water is mixed, and further, if necessary, a specific humectant, an emulsifier, etc., which are preferred concomitant components, are mixed and dissolved to obtain an aqueous phase composition, and b) a composition containing at least solid hydrocarbons, silicones, and higher alcohols is mixed and dissolving the oily component, thereby obtaining an oil phase composition, and c) mixing the water phase composition and the oil phase...

Embodiment 1

[0214] [Preparation of emulsified composition]

[0215] Each component contained in the oil phase composition described in Table 2 - Table 3 was heated and stirred for 1 hour in a constant temperature water tank of 80 degreeC, and the oil phase composition was obtained.

[0216] In addition, in Table 2 - Table 3, each component may be described with the already mentioned abbreviation. "Hydrocarbons that are solid at normal temperature" are described as "solid hydrocarbons", and "a humectant with an I / O value of 2.5 or more" is described as a "specific humectant".

[0217] Each component contained in the water phase composition A described in Table 2 - Table 3 was heated and stirred for 1 hour in an 80 degreeC constant temperature water tank, and the water phase composition A was obtained.

[0218] Emulsion 1 was obtained by adding an oil phase composition to the obtained water phase composition A while stirring using a vacuum emulsification stirring device (model: PVQ-3 / 7UN, ...

Embodiment 2～ Embodiment 7、 comparative example 1～ comparative example 6

[0223] Also about Examples 2 to 7 and Comparative Examples 1 to 6, an oil phase composition, a water phase composition A, and a water phase composition B were prepared according to the formulations described in Tables 2 to 3. An emulsified composition and an aerosol cosmetic were obtained in the same manner as in Example 1 using the obtained oil phase composition, water phase composition A, and water phase composition B.

[0224] [Evaluation of aerosol cosmetic materials]

[0225] The obtained aerosol cosmetics were evaluated as follows, and the evaluation results are described in Tables 2 to 3 below.

[0226] (1. Evaluation of usability)

[0227] The obtained aerosol cosmetic material was sprayed on the palm of the hand in a circular shape with a diameter of about 2 cm, and applied to the facial skin with the fingers.

[0228] As the feeling in use when applied to the facial skin, (1) moisturizing feeling, (2) non-sticky feeling, and (3) irritation were evaluated according ...

Abstract

The invention provides an oil-in-water emulsion composition for carbon dioxide aerosol and an aerosol cosmetic material, which can inhibit skin irritation even in the presence of carbon dioxide gas, have good moisturizing property and no sticky feeling when being applied to the skin, and can form good foam. The oil-in-water emulsion composition comprises: an oily component that contains silicone,a higher alcohol, and a hydrocarbon that is solid at room temperature; and an aqueous component. The total content of the oily components is 6 mass% or more relative to the total amount of the oil-in-water emulsion composition. The oil-in-water emulsion composition is an oil-in-water emulsion composition for an aerosol cosmetic, which contains a carbon dioxide gas as a spray.

Description

technical field [0001] The present disclosure relates to an oil-in-water emulsified composition and an aerosol cosmetic material. Background technique [0002] Aerosol cosmetics made by filling a container with a cosmetic composition and spray gas are used in various applications such as skin cosmetics such as cleansing water and mask cosmetics, hair cosmetics, and shaving creams. [0003] As an aerosol cosmetic material, for example, there is proposed an aerosol formulation composition (for example, Refer to Patent Document 1). [0004] As a massage cosmetic material for improving edema, an aerosol preparation has been proposed. The aerosol preparation is a composition containing silicone and a higher alcohol, and is filled in a container together with liquefied natural gas and used, and is less effective for massaging the lower limbs. Excellent (for example, refer to Patent Document 2). [0005] Furthermore, an aerosol cosmetic containing an emulsion containing astaxant...
