Abstract

PROBLEM TO BE SOLVED: To provide an oil-in-water type emulsion cosmetic capable of obtaining excellent emulsion stability, being easily manufactured regardless of hydrophilic surfactant which is not substantially compounded when powder is compounded in an oil phase, and imparting moisturizing, smooth feeling to the skin, and soft touch without having irritation to the skin.SOLUTION: An oil-in-water emulsion cosmetic includes: (A) hydrophobically modified alkyl cellulose using 14-22C alkyl group; and (B) powder. The (B) power is preferably included in the inner oil phase.

Description

The present invention relates to an oil-in-water emulsified cosmetic containing a powder in an oil phase. More specifically, the present invention relates to an oil-in-water emulsified cosmetic that can stably emulsify an oily phase containing powder by blending hydrophobically modified alkyl cellulose as an emulsifier, and can give a fresh, smooth and soft feel to the skin.

  Oil-in-water cosmetics are widely used to give a fresh and refreshing feel. However, when a powder, particularly a hydrophobized powder, is blended with the internal phase (oil phase), the emulsification system tends to become unstable. Therefore, attempts have been made to stabilize by thickening the outer phase (water phase) of the oil-in-water emulsion base containing the powder. However, the viscosity of the system is reduced by ion elution from the hydrophobized powder. There was a problem of stickiness due to the thickener.

  In Patent Document 1, in an oil-in-water emulsified cosmetic containing a hydrophobized powder, succinoglycan is used as a thickener to be blended in the outer water phase, and a hydrophobic powder such as a nylon resin powder is used as the outer water phase. It is described that stickiness can be eliminated by blending.

On the other hand, even a surfactant used in an oil-in-water emulsion may cause a problem of stickiness and impairing the feeling of use.
Patent Document 2 describes an emulsion composition containing a water-soluble cellulose modified with an alkyl group having 8 to 30 carbon atoms and a higher alcohol that is solid at room temperature having 12 to 28 carbon atoms, and is substantially interfaced. It is said that good usability and emulsification stability can be achieved even without an activator. However, since a solid higher alcohol is contained, a heating step is essential for production, and the process is complicated. Moreover, the characteristic at the time of mix | blending powder is not examined.

  Patent Document 3 discloses an oil-in-water emulsion composition having an average particle diameter of 15 to 500 microns, which contains a non-crosslinked amphiphilic polymer containing alkyl-modified hydroxyethyl cellulose and has an oily phase content of less than 35% by weight. The product has been described and is said to be a composition that is translucent in appearance, not oily to the skin, and stable over a wide viscosity range. However, no study has been made on the characteristics when the powder is blended.

  Patent Documents 4 and 5 describe derivatives in which a glyceryl ether group and a carboxymethyl group, or a glycidyl ether group and a sulfonic acid group are introduced into a polysaccharide such as cellulose, and as a thickener for improving the emulsion stability. It is described that it can be used. However, cellulose derivatives having a sulfonic acid group introduced may show irritation to the skin, and satisfactory results were not obtained even in the feeling of use such as lightness and freshness during application.

  Therefore, the present invention, when blended with powder in the oil phase, provides excellent emulsification stability without substantially blending a hydrophilic surfactant, is easy to manufacture, and is irritating to the skin. Another object of the present invention is to provide an oil-in-water emulsified cosmetic that is fresh and can give a smooth and soft feel to the skin.

  In order to solve the above-mentioned problems, the present inventors have conducted intensive studies, and as a result, by using alkyl cellulose that has been hydrophobically modified with an alkyl group having 14 to 22 carbon atoms as an emulsifier, a substantially hydrophilic surfactant. The oil phase containing powder can be stably emulsified even if it does not contain the oil, and the resulting oil-in-water emulsified cosmetic can be fresh and can provide a smooth and soft feel to the skin, leading to the completion of the present invention. .

  That is, the present invention provides an oil-in-water emulsified cosmetic comprising (A) alkyl cellulose hydrophobically modified with an alkyl group having 14 to 22 carbon atoms and (B) powder.

  In the emulsified cosmetic of the present invention, a specific hydrophobically modified alkyl cellulose acts as an emulsifier, so that a stable emulsion can be formed without blending a hydrophilic surfactant, and the viscosity change over time. Also does not happen. In addition, powders essential for make-up cosmetics can be blended stably, and it is refreshing and excellent in use feeling such as giving smoothness and softness to the skin.

The emulsified cosmetic of the present invention contains (A) alkyl cellulose that is hydrophobically modified with an alkyl group having 14 to 22 carbon atoms (hereinafter referred to as “hydrophobic modified alkyl cellulose”).

From the results shown in Table 1, in the oil-in-water emulsified cosmetic containing powder in the oil phase, the cosmetics of the present invention (Examples 1-1 to 1-3) formulated with hydrophobically modified alkylcellulose as an emulsifier are stable and It was shown that the usability was extremely excellent. In particular, when a lipophilic surfactant (1 to 10% by mass) was added, smoothness was further improved (Examples 1-2 to 1-3). However, in Comparative Example 1-1 in which a hydrophilic surfactant (10% by mass) was blended in place of the lipophilic surfactant, stickiness was produced and the smoothness was reduced.
On the other hand, in Comparative Example 1-2 in which the hydrophobic modified alkyl cellulose was substituted with another general-purpose thickener, a stable and smooth emulsion could not be obtained. For stabilization, a hydrophilic surfactant (1.2 Addition of (mass%) resulted in stickiness and reduced usability (Comparative Example 1-3).

  Even when the oil component constituting the oil phase was variously changed, all measured characteristics were satisfactory (Table 2).

From the results of Table 3, it was shown that the improvement in smoothness due to the blending of the lipophilic surfactant did not depend on the type of the lipophilic surfactant (Examples 3-1 to 3-3).
On the other hand, it was confirmed that the effects of the present invention were also obtained when the alkyl group introduced into the hydrophobically modified alkyl cellulose was changed from the stearyl group (C18) to the cetyl group (C14) (Examples 3-4 and 3- 5). However, a stable emulsion could not be obtained when the water-soluble cellulose ether derivative not hydrophobically modified and the alkyl group to be introduced had a carbon number of less than 14 or 23 or more.
