Abstract

[ problem ] to provide a cosmetic composition which undergoes phase separation upon stable standing. The present invention uses a cosmetic composition that undergoes phase separation upon standing, which comprises an oil component, an oil-soluble film-forming agent, a betaine-type surfactant, and water.

Description

Cosmetic composition
Technical Field
The present invention relates to a cosmetic composition which undergoes phase separation upon standing and a cosmetic product obtained by filling the composition into a dispenser-type container.
Background
Since cosmetics that undergo phase separation when left standing have appearance characteristics of a plurality of phases, they are also used as cosmetics for the purpose of aesthetic appearance. Further, since phase separation occurs during standing, there is an advantage that cosmetic ingredients suitable for each phase can be stably blended, and thus there is an advantage that a desired function can be allocated to each phase.
In general, cosmetics that undergo phase separation are brought into an emulsified state by vibration at the time of use. After use, phase separation again occurs if left to stand. The surfactant is blended to cause such a phase change, but it is known that a time required for separation or an emulsion droplet remains due to the action of the surfactant (for example, patent document 1).
In order to prevent makeup removal and to improve the holding of makeup cosmetics such as foundation, such cosmetics that undergo phase separation are also used as make-up cosmetics that are applied from above the face on which makeup is performed. The user is required to have the functions of adsorbing sebum, protecting skin from dryness, protecting skin from external factors such as pollen and dust, or making up not easily transferred to clothes, etc.

Detailed Description
The present invention relates to a cosmetic composition (hereinafter sometimes referred to as a composition) that undergoes phase separation upon standing, which contains an oil component, an oil-soluble film-forming agent, a betaine-type surfactant, and water.
The composition of the present invention is a cosmetic composition which undergoes phase separation when left to stand, and may have 2 or more phases, preferably 2 phases, and typically an oil phase and an aqueous phase in this order from top to bottom when left to stand. By causing phase separation, cosmetic ingredients, particularly active ingredients, which are matched with each other can be stably blended. In addition, the excellent aesthetic appearance is also preferable because it is associated with an improvement in the sense of swelling and the aggressiveness of the user.

[ oil-soluble film Forming agent ]
The compositions of the present invention comprise an oil-soluble film former.

One of the features of the block copolymer is to have both a resin structure and a linear structure. In general, a polymer is composed of only a resin structure, and film forming property and adhesiveness derived from the structure are excellent, but flexibility and follow-up property are sometimes insufficient. However, when linear structures are combined in a polymer, the polymer becomes both flexible and conformable. When a cosmetic containing a block copolymer having such a characteristic is applied, a soft and adhesive coating film can be formed. It is considered that, when such a coating film is formed after makeup, it functions as a layer for protecting makeup against friction with a mask, clothing, etc., sebum, sweat, etc., and therefore, makeup removal is effectively suppressed.
The resin structure comprises SiO 4/2 The units shown (hereinafter sometimes referred to as Q units) or R 1 SiO 3/2 (R 1 Is C 1-6 Alkyl or C 1-6 Alkoxy, preferably methyl, ethyl, propyl, methoxy, ethoxy or propoxy,more preferably methyl group) (hereinafter, sometimes referred to as T unit), preferably contains Q unit.

In other words, the D unit has a linear structure at a portion where a plurality of D units are connected, preferably 5 or more, and the other Q unit, T unit, D unit, and M unit are mixed and exist at a portion where a resin structure is provided.

[ betaine type surfactant ]
The compositions of the present invention comprise betaine-type surfactants. Examples of the betaine type surfactant include lauryl betaine, cocamidopropyl betaine, amino betaine, and sulfobetaine.
The composition of the present invention contains a betaine type surfactant, and thus, surprisingly, when emulsified by vibration, it can be in a uniform emulsified state and can suppress the generation of aggregates at the interface.
The betaine type surfactant may be blended in an amount of 1 or 2 or more.
The amount of betaine surfactant blended is preferably 0.01 to 0.2 mass%, more preferably 0.02 to 0.1 mass%, relative to the total amount of the composition of the present invention.

The compositions of the present invention may comprise lower alcohols. By compounding a lower alcohol, the specific gravity of the composition can be reduced. In addition, a refreshing feeling can be imparted. Examples of the lower alcohol include ethanol, propanol, isopropanol, isobutanol, and tert-butanol.
The amount of the lower alcohol blended is preferably 1 to 45% by mass, more preferably 5 to 30% by mass, relative to the total amount of the composition of the present invention.
