Embodiment

[0078] Examples are given below to describe the present invention more specifically, but the present invention is by no means limited by them. Unless otherwise specified, the blending amount is expressed in mass % with respect to the system in which the component is blended.

[0079] Before describing the examples, the evaluation method of the test used in the present invention will be described.

[0080] Evaluation (1): Refreshing feeling left after use

[0081] A specific group of 10 people applied the sample on the face, and evaluated the usability at the time of application.

[0082] A*: Nine or more of the 10-person group answered that the residual feeling was refreshing after use.

[0083] A: 7 or more and less than 9 people in the 10-person group answered that the residual feeling was refreshing after use.

[0084] B: 5 or more and less than 7 people in the 10-person group answered that the residual feeling was refreshing after use.

[0085] C: Less than 5 people in...

Abstract

A water-in-oil emulsion composition which, when used as an emulsion makeup base, can be evenly applied and hence enables cosmetics to be spread well. The emulsion composition has a high internal-aqueous-phase proportion that renders the skin fresh and, despite this, gives a sense of thickness, softness, and a moisturizing effect after application. The emulsion composition further has excellent emulsion stability. The water-in-oil emulsion composition is characterized by comprising the following components (A), (B), and (C) and satisfying the following requirements (1) and (2). Components: (A) glycerol isostearate and / or glycerol oleate (B) an aqueous ingredient (C) an oily ingredient comprising a C20 or lower isoparaffin Requirements: (1) The internal-aqueous-phase proportion obtained by dividing the mass of the aqueous ingredient of component (B) by the total mass of the aqueous ingredient of component (B) and the oily ingredient of component (C) is 68% or higher. (2) The amount of glycerol monoisostearate and / or glycerol monooleate contained in component (A) is 85 mass% or larger with respect to the total amount of (A).

Description

[0001] related application [0002] This application claims priority to Japanese Patent Application No. 2009-79894 filed on March 27, 2009, which is incorporated herein. technical field [0003] The present invention relates to a water-in-oil emulsified composition, and particularly relates to a water-in-oil emulsified composition which achieves a high moisturizing effect and improves the richness and softness of the skin after application. Background technique [0004] Emulsion compositions are roughly classified into oil-in-water type (O / W) and water-in-oil type (W / O), and there are also oil-in-water-in-oil type (O / W / O), water-in-oil-in-water type ( W / O / W) and other composite types. Conventionally, these have been utilized in the field of cosmetics for skin care creams, emulsions, hair care creams, and the like, and in the field of pharmaceuticals for transdermal creams and the like. [0005] Among them, since the water-in-oil emulsified composition with the oil phase as...
