Description

TECHNICAL FIELD The present invention relates to an emulsified cosmetic composition.

BACKGROUND ART Emulsified cosmetic compositions having various ingredients and composition ratios have been researched and developed day and night in order to provide various effects on the skin.

Among them, emulsified formulations forming α-gel are known from the viewpoint of excellent occlusive properties during application in skin cosmetics intended for moisturization (for example, Patent Document 1).

JP 2017-132709 A

Generally, α-gel is formed in a mixed system of surfactants, higher alcohols and water and has a bilayer membrane composed of surfactants and higher alcohols. When a highly polar oil is mixed in this system, a large amount of components constituting the bimolecular membrane is distributed to the oil phase side, which poses a problem of impairing the stability of the α-gel.

As a solution to this problem, it has been known in the past to increase the blending amount of the surfactant and/or the higher alcohol, which are constituents of the bilayer membrane. However, as a result of investigations by the present inventors, it has become clear that this solution has problems such as the occurrence of stickiness during use and the deterioration of spreadability of the agent.

An object of the present invention is to provide a highly spreadable and stable α-gel preparation without containing a large amount of surfactants and/or higher alcohols in a preparation containing a highly polar oil.

The present inventors have made intensive studies to solve the above problems. As a result, if a specific polyhydric alcohol is blended in the water phase to adjust the polarity of the water phase side and a specific nonionic surfactant is selected, The inventors have found new knowledge that α-gel can be stably formed in a formulation containing a highly polar oil without adding a large amount of surfactants and/or higher alcohols, and have completed the present invention.

That is, the emulsified cosmetic composition of the present invention includes the following inventions.

(1) containing the following component A, the following component B, the following component C, the following component D, the following component E and the following component F,
The content of the component B is 0.1 to 5.0% by mass,
The content of the component C is 5.0% by mass or less,
The content of the component D is 1.0 to 10.0% by mass,
The content of the component E is 1.0 to 20.0% by mass,
The content of the component F is 50.0 to 90.0% by mass,
The mass ratio of the contents of the component C and the component E (component C/component E) is 0.03 or more,
The mass ratio of the contents of the component A and the component C (component A/component C) is 0.1 to 2.0.
Emulsified cosmetic composition.
Component A: nonionic surfactant having an HLB of 14.0 to 20.0 and having a polyoxyethylene chain Component B: Phospholipid Component C: Aliphatic alcohol having 12 to 22 carbon atoms Component D: Dipropylene glycol and / Or propylene glycol component E: at least one oil component F: water, having an IOB of 0.2 to 0.5 and selected from the group consisting of hydrocarbon oils, ester oils, silicone oils and vegetable oils.

(2) The emulsified cosmetic composition according to (1) above, which forms an α-gel.

INDUSTRIAL APPLICABILITY According to the present invention, a highly spreadable and stable α-gel formulation is provided without containing a large amount of a surfactant and/or a higher alcohol in a formulation containing a highly polar oil.

Although the present invention will be described in detail below, the present invention is not limited thereto.

Unless otherwise specified in this specification, "A to B" representing a numerical range means "A or more and B or less". Unless otherwise specified in this specification, mass % representing the content of an ingredient is a value based on the total mass of the emulsified cosmetic composition as 100 mass %.

Highly polar oils are known to have the effect of softening the stratum corneum and softening the skin (emollient effect), and are blended in various cosmetics. However, when a highly polar oil is blended in an emulsified formulation that forms an α-gel, a large amount of the constituent components of the bilayer membrane (surfactant and higher alcohol) contained in the α-gel are distributed to the oil phase side, resulting in an α-gel structure. has become unstable.

Accordingly, the present invention overcomes the shortcomings of conventional solutions by blending a surfactant with a relatively high HLB with dipropylene glycol and/or propylene glycol. The effect of each component is presumed as follows, but is not limited thereto.
1. A highly polar oil (component E) is blended for the purpose of softening the stratum corneum. However, if left as it is, the bimolecular film-forming component will tend to be distributed to the oil phase side, and α-gel will not be formed.
2. A surfactant (component A) with a relatively high HLB is blended to facilitate the distribution of the bilayer-forming component to the aqueous phase side. However, if left as it is, the curvature of the bilayer membrane becomes too large and α-gel is not formed.
3. A higher alcohol (component C) is blended to reduce the curvature of the bilayer and form α-gel. In the conventional method, since the higher alcohol dissolves in the oil phase, it was necessary to increase the blending amount. However, if too much higher alcohol is blended, the feeling of use deteriorates.
4. Dipropylene glycol and/or propylene glycol (component D) is incorporated to reduce the polarity of the aqueous phase. As a result, the higher alcohol is easily distributed to the oil-water interface, so that the α-gel is formed without increasing the blending amount of the higher alcohol.
