Description

Oil painting cosmetic

The present invention relates to an emulsion cosmetic.

A cosmetic that can provide a rich feeling to a user at the time of application can be said to be one of the cosmetic types required by the user, because the user can feel the comfort of the seedlings and at the same time produce a sense of luxury. Conventionally, it has been known to blend high-grade alcohol or polyethylene glycol as an emulsifying cosmetic that gives the skin a rich feeling (Patent Document 1).

Japanese Patent Application No. 2013-018724

However, emulsions containing higher alcohols have a problem of thickening over time. For example, when such a fluid was filled into a dispenser container or a lotion bottle, there was a case where a problem occurred in the ejectability from the nozzle. For this reason, the compounding amount of higher alcohol is inevitably limited, and it is difficult to provide a sufficiently high rich feeling. In addition, the emulsified cosmetic composition containing polyethylene glycol has a problem such as insufficient usability.

Further, even if an emulsion-based composition with sufficient richness is provided, a composition such as poor emulsion uniformity or poor storage stability at high temperatures as well as low temperatures cannot be said to be sufficient as an emulsion cosmetic. .

An object of the present invention is to provide an emulsifying cosmetic that is excellent in storage stability even at high temperatures, while providing a rich feeling and having excellent emulsion uniformity.

That is, the present invention contains the following component A, the following component B, the following component C, and the following component D,

The content of the component A is 0.5 to 4.0 mass%, the sum of the content of the component B and the component C (B + C) is 0.5 to 6.0 mass%, and the total of the content of the component B and the component C is The mass ratio (B / (B + C)) of the content of the said component B is 0.15 to 0.85, and it is related with the emulsion cosmetic.

Component A: Phospholipid

Component B: glyceryl monobehenate

Component C: glyceryl monostearate

Ingredient D: water

ADVANTAGE OF THE INVENTION According to this invention, the emulsion cosmetics excellent in the uniformity of emulsion and excellent in storage stability even at high temperature can be provided, providing a rich feeling. In addition, the above-mentioned "rich feeling" means the texture as the thickness of the coating layer of the agent is felt at the time of application, and the agent having a high concentration is applied.

The emulsifying cosmetic of the present invention contains at least components A to D.

The present inventors have discovered that among the various types of ingredients usable in the cosmetic field, phospholipids are paid attention, and the emulsified cosmetic emulsified by phospholipids exhibits a somewhat high rich feeling. However, in the case of an emulsified cosmetic emulsified with phospholipids, the uniformity of emulsification may be lowered, or storage stability such as separation at high temperature may decrease. Therefore, as a result of further examination, by using glyceryl monobehenate and glyceryl monostearate at a specific ratio, not only the rich feeling is improved, but also an emulsion cosmetic having excellent emulsion uniformity and storage stability at high temperature is obtained. Found something.

Component A is a "phospholipid". Component A exhibits not only an effect of promoting emulsification but also an effect of providing a rich feeling.

Component A is a complex lipid containing a phosphoric acid residue, and may include natural phospholipids, synthetic phospholipids, and hydrogenated phospholipids in which the unsaturated carbon chains of naturally occurring phospholipids are saturated with hydrogen. The phospholipids include, for example, natural phospholipids such as phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, lysophosphatidylcholine, sphingomyelin, egg yolk lecithin, soy lecithin; Synthetic phospholipids such as dilauroylphosphatidylcholine, dimyristoylphosphatidylcholine, dipalmitoylphosphatidylcholine, distearoylphosphatidylcholine, dioleoylphosphatidylcholine, palmitoyl-oleoylphosphatidylcholine; Hydrogenated phospholipids such as hydrogenated soybean lecithin, hydrogenated egg yolk lecithin, hydrogenated phosphatidylcholine, and hydrogenated phosphatidylserine. Among them, from the viewpoint of storage stability at high temperature, hydrogenated phospholipids are preferred, and hydrogenated soybean phospholipids are more preferred. As for the component A, only 1 type may be used and 2 or more types may be used.

A commercial item can be used as component A.

Component C is "monostearic acid glyceryl". Component C exerts an effect of imparting a rich feeling upon application of the emulsifying cosmetic, and further improving the uniformity of the emulsion of the emulsifying cosmetic. Since glyceryl monostearate of component C has a short carbon chain length and high interfacial activity, it is presumed to exhibit the effect of increasing the uniformity of the emulsion by oriented at the oil-water interface. Moreover, the uniformity of an emulsion means that coarse aggregates do not generate | occur | produce in an emulsion, for example.
