Description

  The present invention relates to an oily cosmetic, and more specifically, it forms a decorative film having an excellent gloss feeling and an appropriate and uniform film thickness, and is excellent in smooth use feeling, non-stickiness and durability of a moist feeling. It relates to oily cosmetics.

Conventionally, oily cosmetics typified by lipstick have been studied for selection of blending ingredients and blending ratios in order to obtain various sensuality and cosmetic effects. In recent years, glossy and transparent decorative films tend to be preferred. In order to obtain a glossy decorative film, oily cosmetics containing a liquid polyolefin polymer as an oil agent have been proposed. For example, oily cosmetics containing polybutene (Patent Document 1) and oily cosmetics containing isoparaffin, normal paraffin and polybutene (Patent Document 2) have been proposed. A gelling agent that gels the oil is blended in the oily cosmetic containing these oils. In Patent Document 1, dextrin fatty acid ester and / or 12-hydroxystearic acid is used as the oil gelling agent. It is said that oil gel cosmetics with good gloss and spread and excellent usability and stability can be obtained by synergistic effects with polybutene. In addition, an oily cosmetic is proposed in which diisostearyl malate is used as an oil agent and a dextrin fatty acid ester is used in combination as a gelling agent (Patent Document 3). With this combination, the gloss is good, there is no smell, and it is heavy. It is said that oily cosmetics with little feeling of use and stickiness and excellent shape retention and stability were obtained. On the other hand, it has been proposed to use an inulin sugar fatty acid ester as a gel structure-imparting agent for volatile cyclic silicone (Patent Document 4).

  The oily cosmetics containing polybutene, paraffin and oil gelling agent as shown in Patent Document 1 and Patent Document 2 are excellent in terms of gloss, but the stickiness of the cosmetic film and the weight of the spread The usability was not satisfactory. In addition, although the oil agent such as diisostearyl malate shown in Patent Document 3 can reduce stickiness compared to polybutene, it has not yet been satisfactory in terms of gloss, adhesion and moisture. It is an object of the present invention to provide an oily cosmetic material having an appropriate and uniform film thickness, excellent gloss, smooth use feeling, non-stickiness and excellent moisture. To do.

As a result of intensive studies to solve the above problems, the present inventors have found that a fructooligosaccharide fatty acid ester having a specific degree of sugar polymerization and a specific degree of fatty acid esterification, such as heavy liquid isoparaffin, α-olefin oligomer, etc. With specific hydrocarbon oil, we found that it formed a cosmetic film with excellent usability such as non-stickiness and good stretch while maintaining gloss, and by adding phenyl group-containing organopolysiloxane, The inventors have found that the stickiness can be further reduced and the gloss can be improved, and the present invention has been completed.

That is, the present invention includes the following components (A) to (C):
(A) Fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 10 or more and 60 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more (B) Heavy liquid isoparaffin and a weight average molecular weight of 500 to 5000 An oily cosmetic characterized by containing one or more hydrocarbon oils (C) phenyl group-containing organopolysiloxane selected from α-olefin oligomers.

  The component (A) is a fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 10 or more and 60 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more, and the total acyl of the fatty acid ester Fructooligofatty acid esters in which 60 mol% or more of the groups are one or two or more acyl groups selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group and a docosanoyl group are preferred. The component (C) is preferably a phenyl group-containing organopolysiloxane having a refractive index of 1.48 or more at 25 ° C.

  The oily cosmetic of the present invention uses a hydrocarbon oil selected from heavy fluid isoparaffin and α-olefin oligomer having a weight average molecular weight of 500 to 5000 as an oil agent in order to improve the gloss of the decorative film. As the agent, a fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 10 or more and 60 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more was further blended with a phenyl group-containing organopolysiloxane. It has an excellent glossiness, a moderate and uniform film thickness, can form a non-sticky cosmetic film, and has a smooth feeling of use and a long lasting feeling of moisture.

  The component (A) of the present invention will be described. Component (A) is a fructooligosaccharide fatty acid ester having an average sugar polymerization degree of 10 or more and 60 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more. Fructooligosaccharide fatty acid esters are known (Japanese Patent Laid-Open Nos. 3-197409 and 2002-193732). The fructooligosaccharide which is a raw material for the fructooligosaccharide fatty acid ester of component (A) is an oligosaccharide having fructose as a main constituent sugar. Fructooligosaccharides are contained in various plants such as roots, stems, leaves, and seeds of Asteraceae, Gramineae and Liliaceae, and their structures are such that the main chain has a 2 → 1 bond and 2 → There are two types of 6 bonds. Examples of the 2 → 1 bond include fructooligosaccharides derived from inulin, asparagosin, asphodelan, triticane, criticzan, and Bacmondo, and examples of the 2 → 6 bond include Flaen, Levan, and Ceracan. Either can be used. Among these fructooligosaccharides, inulin is particularly preferable from the viewpoint of physical properties and supply.

The fructooligosaccharide fatty acid ester of component (A) used in the present invention has a sugar average polymerization degree of 10 or more and 60 or less. The method for measuring the average degree of polymerization of the sugar is described in, for example, L. De Leenheer, Starch 46 (5), p193-196 (1994), Carbohydrates as Organic Raw Materials, Vol.III, p67-92 (1996). By setting the sugar average polymerization degree in the range of 10 or more and 60 or less, as will be described later, a high gelling ability can be exerted on the hydrocarbon oil of the component (B), and the desired gel hardness can be imparted.

The fructooligosaccharide fatty acid ester is obtained by replacing the hydrogen atom of the hydroxyl group of fructooligosaccharide with an acyl group RCO- (wherein R represents a linear or branched alkyl group or alkenyl group having 7 to 32 carbon atoms). That is, this fructooligosaccharide fatty acid ester is obtained by reacting a fructooligosaccharide with a fatty acid represented by the formula RCOOH (where R is the same as above) or a reactive derivative thereof, specifically an acid halide, an acid anhydride, or the like. Manufactured. This reaction can be performed by a conventionally known method. For example, it can be obtained by dispersing fructooligosaccharide in dimethylformamide and pyridine, adding a fatty acid halide or a fatty acid anhydride thereto, and reacting at about 60 ° C. for about 2 hours.

In the component (A) of the present invention, a fatty acid esterification degree per monosaccharide unit is 2.2 or more, that is, an average of 2.2 or more hydroxyl groups substituted per monosaccharide unit is used. When the degree of substitution is 2.2 or more, the gel structure is more easily formed due to good solubility in the oily base material containing the hydrocarbon oil of component (B), and the stability is further improved and separation is performed. Is hard to get up. On the other hand, if the degree of substitution is lower than 2.2, it is difficult to form a gel structure due to low solubility in an oily substrate, and it may be difficult to ensure stability.

  In addition, in the fructooligosaccharide fatty acid ester of the component (A) of the present invention, one or two kinds in which 60 mol% or more of the total acyl groups are selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group or a docosanoyl group The above is preferable. If the total amount of these acyl groups is 60 mol% or more, the stability of the gel composition or cosmetic of the present invention is further improved. With regard to the carbon chain length of the acyl group, the acyl group having a carbon number smaller than that of the hexadecanoyl group may not give sufficient gel hardness, and conversely, the acyl group having a carbon number greater than that of the docosanoyl group may be heavy when used. The gelling agent may precipitate over time.

  In the fructooligosaccharide fatty acid ester in which 60 mol% or more of the total acyl groups is one or more selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group and a docosanoyl group, the other acyl groups include acetyl groups, Propionyl, butyryl, isobutyryl, valeryl, isovaleryl, pivaloyl, hexanoyl, octanoyl, decanoyl, dodecanoyl, tetradecanoyl, tetracosanoyl, hexacosanoyl, octacosanoyl, triacontanoyl, ole An oil group, a benzoyl group, a naphthoyl group, etc. can be illustrated.

  The present invention relates to an oily cosmetic containing one or more hydrocarbon oils selected from heavy liquid isoparaffin and an α-olefin oligomer having a weight average molecular weight of 500 to 5000 in order to improve the gloss of the decorative film. In order to provide a uniform film thickness, smooth feeling of use, and no stickiness while maintaining the gloss, component (A) has a sugar average polymerization degree of 10 or more and 60 or less, per monosaccharide unit. The fructooligosaccharide fatty acid ester having a fatty acid esterification degree of 2.2 or more is used as a gelling agent for the hydrocarbon oil. The above-mentioned effect is due to the gelation effect of the above specific fructooligosaccharide fatty acid ester, as can be seen from the experiment on the oily gel composition comprising the following component (A), component (B), and component (C). Is based.

[Experiment]
The components of Experimental Examples 1 to 4 and Comparative Experimental Examples 1 to 8 shown in Table 1 were heated, dissolved, mixed, and then cooled to prepare an oily gel composition. The gel hardness of this oily gel composition was measured. In addition, an oily gel composition was applied to the inner part of the forearm by 10 specialist panels, and each panel scored using sensory evaluation for film thickness, gloss, smoothness, and no stickiness, using the following evaluation criteria a. And the average value calculated from the total score of all the panel members for each sample was determined using the following criteria b. The results are also shown in Table 1.

<Gel hardness>
The composition shown in Table 1 was heated and dissolved at 80 ° C., and then allowed to stand in a thermostatic bath at 25 ° C. for 3 hours, and then the gel hardness was measured. The gel hardness was a rheometer manufactured by FUDOH, using a Φ10 mm plunger, and the load peak value (g) when entering 3 mm at an approach speed of 6 cm / min was defined as the gel hardness.

  From the results of Table 1, the fructooligosaccharide fatty acid ester having a specific sugar polymerization degree range or higher and having a specific fatty acid esterification degree or more used in the present invention is compared with the heavy liquid isoparaffin and α-olefin oligomer of the component (B) of the present invention. It can be seen that an oily gel having excellent gelling ability and excellent film thickness, gloss, smoothness and non-stickiness is formed (Experimental Examples 1 to 3). On the other hand, the fructooligosaccharide fatty acid ester or dextrin palmitate ester having a sugar polymerization degree outside the range of the present invention has no gelling ability with respect to the component (B) of the present invention, and lacks a sense of smoothness. However, the composition was terrible (Comparative Experimental Examples 1 to 6). In addition, the fructooligosaccharide fatty acid ester used in the present invention has an excellent gelation ability even with respect to a mixture of component (B) and diphenyldimethicone, and has a good gloss, film thickness, smoothness, and no stickiness. The fructooligosaccharide fatty acid ester or dexramrmitic acid ester having a sugar polymerization degree outside the scope of the present invention is extremely inferior in gelling ability to a mixture of diphenyldimethicone and functionally. In particular, it was not smooth and was not very sticky (Comparative Experimental Examples 7 and 8).

  A lip gloss having the composition shown in Table 2 was prepared, and each sample was subjected to a sensory test by 10 specialist panels.

In addition, the present invention products 2 to 3 which show good results in all items, and in particular blend a phenyl group-containing organopolysiloxane having a refractive index of 1.48 or more, are particularly excellent in gloss feeling compared to the present invention product 1. Lip gloss. On the other hand, the comparative products 1 to 4 are not satisfactory in all items, and the comparative product 1 containing no phenyl group-containing organopolysiloxane is slightly inferior in glossiness, smooth use feeling, and no stickiness. Comparative product 2 using a fructooligosaccharide fatty acid ester having a sugar average polymerization degree of less than 10 as a gelling agent was too soft and was particularly inferior in uniform film thickness and non-stickiness. Comparative products 3 to 4 using dextrin palmitate or wax as a gelling agent were heavy and had a sticky feeling and were inferior in all usability such as a glossy feeling.
