Description

  The present invention relates to a cosmetic having a moisturizing effect, excellent skin conformability and slipperiness during application, excellent film feeling after application, and good emulsification stability.

  Cosmetics such as milky lotion and moisturizing cream are indispensable for daily skin care in order to protect the skin and hair from moisture, transpiration and the external environment. These cosmetics are blended with an oil agent to give a smooth feel in addition to the purpose of moisturizing, moisture transpiration and protection from the external environment. Therefore, cosmetics generally take the form of emulsification such as oil-in-water emulsification in which an oil is dispersed in an aqueous phase and water-in-oil emulsification in which an aqueous phase is dispersed in an oil.

  A surfactant is indispensable for stabilizing the emulsification, and among them, a nonionic surfactant is widely used because of its high emulsifying power.

Nonionic surfactants have a wide variety of structures. When blended in cosmetics, in addition to the above-mentioned high emulsifying power, the skin feels and feels smooth when applied. It is required not to impair the smooth feel. In addition, recent consumer needs are demanding that the film feel after application is good.
Accordingly, there is a need for the development of a cosmetic material that has a high moisturizing effect, has a feeling of skin conformity and slipping when applied to the skin and hair, and a good coating feeling after application, and has high emulsification stability.

  In order to achieve such problems, it is important to use a nonionic surfactant that exhibits high emulsifying ability even at low concentrations. Conventionally, an alkyl that exhibits high self-emulsifying ability and high emulsifying ability when used alone. There is a proposal of glucoside (for example, Patent Document 1). This proposal discloses a method for using alkyl glucosides having low toxicity and providing emulsion stability, particularly alkyl glucosides having an alkyl group of 16 to 18 carbon atoms. However, since the alkyl glucoside itself has a high melting point and high crystallinity, it is not suitable for the smoothness of the oil agent due to poor skin fit and slipperiness. Moreover, when preparing an oil-in-water emulsion by general phase inversion emulsification, it tends to aggregate in the cooling process after phase inversion, and it has been difficult to ensure sufficient emulsification stability.

  For such a problem, there is also a proposal in which a fatty acid partial glyceride having a monoglyceride content of 60 to 95% and an alkyl glucoside are combined (for example, Patent Document 2). This proposal discloses that a fatty acid partial glyceride inhibits the crystallinity of alkyl glucoside to obtain a stable emulsion. However, this technique is not sufficiently satisfactory in terms of the durability of the moisturizing effect, the familiarity and slipperiness of the skin at the time of application, and the film feeling after application.

  Furthermore, there is also a proposal of a microemulsion containing alkylglycoside, HLB10-16 hydrophilic nonionic surfactant, hydrophilic amphiphile, and polyhydric alcohol as essential components (Patent Document 3). In this proposal, aralkyl glucoside is mainly blended, but since it is a small amount (0.1 to 1.5% by weight), it does not cause crystal formation and a stable microemulsion is obtained. However, in addition to the alkyl glycoside, it is necessary to use a hydrophilic nonionic surfactant in combination, which is not satisfactory in terms of skin conformability and slipperiness during application.

[Component (A): Alkyl glycoside having a linear saturated alkyl group having 14 to 22 carbon atoms]
Component (A) is an essential component for providing emulsion stability. The alkyl glycoside having a linear saturated alkyl group having 14 to 22 carbon atoms is represented by the following formula (3).

In the formula (3), R ² is a linear saturated alkyl group having 14 to 22 carbon atoms. The carbon number of R ² is more preferably 16 or more, and further preferably 18 or less, which further improves the emulsion stability. Examples of R ² include a myristyl group, a cetyl group, a stearyl group, an aralkyl group, and a behenyl group, but a cetyl group and a stearyl group are preferable, and a mixture of a cetyl group and a stearyl group is particularly preferable. In the case of a mixture of a cetyl group and a stearyl group, an equal mass mixture is most preferable.

Component (A) can be obtained by a known production method. For example, after dehydration condensation of a higher alcohol: R ² —OH and glucose under an acid catalyst, or after obtaining a lower alkyl glucoside with a lower alcohol such as methanol or butanol under an acid catalyst, the higher alcohol: R ² —OH The acetal exchange reaction can be obtained. At this time, it is known that a condensate of carbohydrates such as glucose can also be obtained by an acid catalyst. In the formula (3), n is the condensation degree of the saccharide and is 1 to 3. However, the object of the present invention can be achieved at any condensation degree.

  Further, the saccharide moiety of formula (3) 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 condensates thereof, and particularly preferred are glucoside and polyglucoside.

  A component (A) is contained 0.01-5 mass% with respect to the total mass of the cosmetics of this invention. If it is less than 0.01% by mass, the desired emulsion stability cannot be obtained, which is not preferable. In this respect, 0.1% by mass or more is more preferable. Moreover, when it exceeds 5 mass%, it is inferior to the skin conformity and slipperiness at the time of application | coating, and is not preferable. In this respect, 4% by mass or less is preferable, 3% by mass or less is more preferable, and 2% by mass or less is most preferable.

[Component (B): a monohydric alcohol represented by the formula (1). ]
Component (B) is a monohydric alcohol having a linear saturated alkyl group having 14 to 22 carbon atoms as R ¹ , and is an essential component for improving emulsification stability, skin familiarity and slipperiness. The linear saturated alkyl group preferably has 16 or more carbon atoms, more preferably 18 or less. Examples of R ¹ include a myristyl group, a cetyl group, a stearyl group, an aralkyl group, and a behenyl group, preferably a cetyl group and a stearyl group, and more preferably a mixture of a cetyl group and a stearyl group. In the case of a mixture of a cetyl group and a stearyl group, an equivalent mixture is most preferable.
Alternatively, ^{R 1} and ^{R 2} of formula (3) in equation (1) are preferably the same alkyl group.

  A component (B) is contained 0.05-20 mass% with respect to the total mass of the cosmetics of this invention. If it is less than 0.05% by mass, it is not preferable because the desired skin fit, slipperiness and emulsion stability cannot be obtained. In this respect, 0.1% by mass or more is more preferable, and 0.5% by mass or more is more preferable. On the other hand, if it exceeds 20% by mass, it may be unfavorable because it may impair skin fit and slipperiness during application. In this respect, 15% by mass or less is preferable, and 12.5% by mass or less is more preferable.

  Moreover, when the total mass of a component (A) and a component (B) is 100 mass parts, it is preferable that the quantity of a component (B) is 75-95 mass parts. By making the amount of the component (B) 75 parts by mass or more, the slip feeling is further improved. In this respect, the amount of component (B) is more preferably equal to or greater than 80 parts by weight. Moreover, emulsification stability improves by making the quantity of a component (B) 95 mass parts or less. From this viewpoint, the amount of the component (B) is more preferably 92.5 parts by mass or less, and still more preferably 90 parts by mass or less.

[Alkylene oxide derivative of component (C)]
Component (C) is an essential component for imparting the durability of the moisturizing effect, the familiarity and slipperiness of the skin during application, and the film feeling after application.

The component (C) is represented by the following formula (2).
Z- {O (EO) x (PO) y- (BO) z-H} a (2)

  In formula (2), Z is the residue remove | excluding all the hydroxyl groups from the polyhydric alcohol which has 2-9 hydroxyl groups, and a is 2-9. As such a polyhydric alcohol, for example, if a = 2, ethylene glycol, diethylene glycol, 1,2-propylene glycol, dipropylene glycol, 1,3-propylene glycol, 1,3-butylene glycol, 1,4 -Butylene glycol, if a = 3, glycerin, trimethylolpropane, if a = 4, methyl glucoside, ethyl glucoside, butyl glucoside, erythritol, pentaerythritol, diglycerin, sorbitan, if a = 5, Examples include xylitol, if a = 6, sorbitol, dipentaerythritol, inositol, if a = 8, sucrose, trehalose, if a = 9, maltitol, and a mixture thereof. Preferably, Z is a residue obtained by removing a hydroxyl group from a water-soluble polyhydric alcohol having 2 to 6 hydroxyl groups, and a is 2 to 6. More preferred are glycerin, methyl glucoside and sorbitol. When a is larger than 9, the skin familiarity and slipperiness at the time of application deteriorate, which is not preferable.

  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 the number of moles added of the oxyethylene group and the oxypropylene group, and 1 ≦ x ≦ 20 and 1 ≦ y ≦ 10, respectively. When x is smaller than 1, it is not preferable because sufficient moisturizing effect and film feeling after application cannot be obtained. From this viewpoint, x is more preferably 2 or more. Moreover, when x exceeds 20, it is inferior to the skin familiarity at the time of application | coating, a slipperiness, and emulsification stability. From such a viewpoint, x is preferably 15 or less, and more preferably 10 or less.

  If y is less than 1, the durability of the moisturizing effect is poor, and the desired film feeling cannot be obtained, which is not preferable. From this viewpoint, y is more preferably 2 or more. Moreover, even if y exceeds 10, the sustainability of the moisturizing effect and the film feeling after application may be impaired, which is not preferable. From such a viewpoint, y is more preferably 8 or less, and most preferably 6 or less.

  The mass ratio of EO to the total mass (100 mass%) of EO and PO is 30 to 80 mass%. If this is less than 30% by mass, the durability of the moisturizing effect and the film feeling after application may be impaired, which is not preferable. From such a viewpoint, the EO mass ratio is more preferably 40% by mass or more, and most preferably 50% by mass or more. Moreover, when it exceeds 80 mass%, it is inferior to the skin familiarity at the time of application | coating and a feeling of slip. Furthermore, when it exceeds 80 mass%, the inhibitory effect of the crystallinity of a component (A) will fall and it will be inferior to emulsion stability. From such a viewpoint, the EO mass ratio is more preferably 78% by mass or less.

  EO and PO are added randomly. If it is added in the form of a block, it may be inferior to the skin fit and slipperiness.

  BO is an oxybutylene group, and is preferably an oxybutylene group derived from 1,2-epoxybutane, that is, an oxyethylethylene group. In this case, BO 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 fit and slipping feeling during coating. Furthermore, lipophilicity can be imparted by BO, and the effect of promoting emulsion stability is also brought about.

  z is the average added mole number of BO, 1 ≦ z ≦ 2, and preferably z = 1. When z = 0, skin conformability is deteriorated and emulsification stability is deteriorated, which is not preferable.

  The molecular weight of the alkylene oxide derivative of the formula (2) is not particularly limited, but the average molecular weight is preferably 900 to 4000 in order to obtain a further film feeling. Here, the average molecular weight is obtained by the hydroxyl value described in “JIS K-1557 1”.

  The cosmetic of the present invention contains 0.1 to 30% by mass of the component (C). If this is less than 0.1% by mass, the moisturizing effect will be inferior, and the skin-familiarity, slipperiness and film feeling may be impaired. Furthermore, when less than 0.1 mass%, the crystallinity of a component (A) cannot be inhibited and it will be inferior to emulsion stability. From such a viewpoint, 0.5% by mass or more is more preferable, and 1% by mass or more is most preferable. On the other hand, if it exceeds 30% by mass, the skin will become familiar and slippery at the time of application, and the emulsion stability will be poor. From such a viewpoint, 28 mass% or less is preferable, 25 mass% or less is more preferable, and 20 mass% or less is the most preferable.
