Description

  The present invention relates to a cosmetic material that maintains a moisturizing effect, is excellent in skin familiarity after application, a feeling of elasticity, and freshness, and has excellent stability.

  In cosmetics such as milky lotion and moisturizing cream, the moisturizing effect is the most basic function. On the other hand, recent consumers prefer not only a moisturizing effect but also an excellent touch. In particular, there is a growing need for a preparation that is excellent in skin familiarity and that gives a good feeling of elasticity and freshness after application.

  Cosmetics generally control the feeling of use by utilizing characteristics such as polarity and melting point of the oil used. As the oil agent, ester oils such as olive oil and jojoba oil, and hydrocarbon oils such as petroleum jelly, liquid paraffin, and squalane are particularly widely used. In order to stably mix water and these oils, it is common to use the emulsifying power of nonionic surfactants. However, even if an oil with a good feeling of use is used, the feel may be deteriorated by a surfactant or a humectant. For example, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene hydrogenated castor oil, polyglycerin fatty acid ester, etc. are widely used as surfactants with high emulsifying power, but they deteriorate the feel during application such as stickiness. It was difficult to give a good feeling of elasticity after application. Polyhydric alcohols such as glycerin and sorbitol have a high moisturizing effect and are widely used. However, it is difficult to obtain stability due to stickiness and poor compatibility with oils and emulsifiers.

  In order to solve such a problem, a proposal has been made to contain a linear alkylene oxide derivative excellent in a moisturizing effect, a feeling of use, and a rough skin improving effect (for example, Patent Document 1). This proposal is excellent in moisturizing effect, smoothness to the skin and non-stickiness, skin roughness improvement effect, and skin irritation, but is not sufficient to give a feeling of stickiness and freshness after application.

  Furthermore, there has been proposed a skin cosmetic that brings a feeling of elasticity to the skin by using an alkylene oxide derivative having a glycerin skeleton in combination with a water-soluble polymer compound such as xanthan gum or hydroxyethyl cellulose (for example, Patent Document 2). In this proposal, stickiness due to the water-soluble polymer compound occurs, and a sufficient feeling of elasticity and freshness cannot be obtained, and there is a problem in stability.

  No cosmetics have been provided so far that have a moisturizing effect, excellent skin fit, smoothness and freshness after application, and good stability. The present invention provides a cosmetic having such properties, and is therefore extremely useful in the industry.

[Component (A): alkylene oxide derivative represented by formula (I)]
In the formula (I), G is a residue obtained by removing a hydroxyl group from an alkyl glycoside having an alkyl having 1 to 4 carbon atoms. Alkyl glycosides are essential for giving a feeling of stickiness and freshness after application. The alkyl glycoside can be represented by the formula (II).

  In the formula (II), R is an alkyl group having 1 to 4 carbon atoms, and may be either linear or branched. When the carbon number of R is 5 or more, it is not preferable because it may impair the freshness and stability only after coating. Specifically, examples of R include a methyl group, an ethyl group, a propyl group, an isopropyl group, an n-butyl group, an isobutyl group, and a t-butyl group, and a methyl group, an ethyl group, and an n-butyl group are preferable. A methyl group and an n-butyl group are more preferable, and a methyl group is most preferable.

  The derivative of the formula (II) may be D-form, L-form or racemic form, and the anomeric center may be α-type or β-type. Moreover, there is no restriction | limiting in particular also about the solid of a hydroxyl group. Accordingly, examples of glycosides include glucoside, galactoside, mannoside, fructoside, and the like, with glucoside being particularly preferred.

  Accordingly, the alkyl glycoside is preferably methyl glucoside, ethyl glucoside, or n-butyl glucoside, and more preferably methyl glucoside.

  EO is an oxyethylene group. PO is an oxypropylene group. PO is preferably an oxypropylene group derived from 1,2-propylene oxide, that is, an oxymethylethylene group.

  x and y are average addition mole numbers of an oxyethylene group and an oxypropylene group, respectively, 5 ≦ x ≦ 20 and 1 ≦ y ≦ 10. If x is smaller than 5, it is not preferable because sufficient moisturizing effect cannot be obtained. From this viewpoint, x is more preferably 6 or more. Moreover, when x exceeds 20, the skin familiarity and freshness after application | coating and the sustainability of a moisturizing effect are also inferior. From such a viewpoint, x is preferably 15 or less, and more preferably 10 or less.

  When y is smaller than 1, the durability of the moisturizing effect is inferior, and the feeling of stickiness after application is deteriorated. From such a viewpoint, y is more preferably 2 or more. Moreover, when y exceeds 10, it is not preferable because stability is impaired. From this viewpoint, y is more preferably 5 or less, and most preferably 3 or less.

  The weight ratio of EO to the total mass (100% by mass) of EO and PO is 55 to 90% by mass. If it is less than 55% by mass, the durability of the moisturizing effect is inferior, and freshness and stability cannot be maintained only after application, which is not preferable. From such a viewpoint, the EO mass ratio is more preferably 60% by mass or more. On the other hand, if it exceeds 90% by mass, the sustainability of the moisturizing effect is inferior, and a feeling of stickiness after application cannot be obtained, which is not preferable. From this viewpoint, the mass ratio of EO is more preferably 86% by mass or less, and most preferably 80% by mass or less.

  EO and PO are added randomly. If it is added in a block shape, the familiarity with the skin after application is deteriorated, which is not preferable.

  BO is an oxybutylene group derived from 1,2-epoxybutane, that is, an oxyethylethylene group. BO therefore has an ethyl branch. When BO is addition-polymerized to the terminal hydroxyl group, the ethyl branched chain has an effect of relaxing the hydrogen bond of the hydroxyl group, and is an essential component for improving skin familiarity after coating. Furthermore, lipophilicity can be imparted by BO, and the effect of promoting stability is also brought about.

  z is the average added mole number of BO, 1 ≦ z ≦ 2, and preferably z = 1. When z = 0, not only the spread during application deteriorates, but also stability cannot be obtained. On the other hand, if it exceeds 2, the cloud point is lowered, so that the stability is inferior, which is not preferable.

The alkylene oxide derivative of the formula (I) has an average molecular weight of 1800 or more and 4000 or less . If the average molecular weight is less than 1800, the desired feeling of stickiness and freshness after application cannot be obtained, which is not preferable. From this viewpoint, the average molecular weight of the alkylene oxide derivative of the formula (I) is preferably 2000 or more, and more preferably 2100 or more. The average molecular weight of the alkylene oxide derivative of formula (I), more than 4000 and Suruga, more preferably 3900 or less, more preferably 3700 or less, most preferably 3000 or less.

Here, the average molecular weight is “JIS”.
It is obtained by the hydroxyl value described in “K-1557 1”.

  Further, the alkylene oxide derivative of the formula (I) preferably has a cloud point of 50 to 80 ° C. in a 10% by mass aqueous solution. By setting the cloud point to 50 ° C. or higher, the stability of the cosmetic is improved. Further, when the cloud point is 80 ° C. or higher, the desired feeling of stickiness after coating is further improved. This cloud point is calculated | required as the temperature which heated the 10 mass% aqueous solution of the alkylene oxide derivative, and became cloudy.

  The cosmetic of the present invention contains 0.01 to 30% by mass of the component (A). Preferably, it is 0.1-25 mass%, More preferably, it is 0.1-10 mass%. When the ratio of the component (A) is less than 0.01% by mass, it is not preferable because the durability of the moisturizing effect, the skin familiarity after application, the feeling of elasticity after application, and the freshness after application cannot be obtained. If it exceeds 30% by mass, the familiarity with the skin after application is not sufficient, and the stability may be impaired, which is not preferable.

[Production of alkylene oxide derivative represented by formula (I)]
The alkylene oxide derivative represented by the formula (I) of the present invention can be produced by a known method. For example, it can be obtained by addition-polymerizing ethylene oxide and propylene oxide to an alkyl glucoside represented by the formula (II) in an alkali catalyst and then adding a butylene oxide having 4 carbon atoms.
