Description

oily composition

[0001] This invention relates to an oily composition.

[0002] Generally, oil-based compositions are widely used in makeup cosmetics such as lipstick, lip gloss, foundation, and eyeshadow due to their excellent usability and portability. Their components consist of oily components such as liquid oil, semi-solid oil, and solid oil, powders such as coloring pigments and extender pigments, and oil-based gelling agents. In particular, for lip cosmetics such as lipstick, in addition to the feel of use, such as smooth application and non-stickiness, and the finish of the cosmetic film, such as color development and gloss, the longevity of the texture immediately after application and the secondary adhesion-free effect, which prevents the lipstick applied to the lips from transferring to clothing or cups, are also important qualities that are required. Various studies have been conducted to realize the secondary adhesion-free effect in addition to a good feel and gloss of the applied film. For example, techniques have been disclosed for obtaining a gel with excellent transparency by combining a specific alcohol, a glyceryl monofatty acid ester, and an ethylcellulose polymer (Patent Document 1), and for maintaining the gloss and non-bleeding properties of a cosmetic film by combining a specific polysaccharide polymer and a liquid polymer (Patent Document 2).

[0003] Japanese Patent Publication No. 2023-553705, Japanese Patent Publication No. 2011-121979

[0004] However, for example, the oily composition described in Patent Document 1 imparts gloss to the cosmetic film by forming a transparent gel, but it did not focus on the persistence of gloss over time or the effect of reducing secondary adhesion. Also, for example, the cosmetic composition described in Patent Document 2 imparts a high level of shine that lasts for a long time and suppresses bleeding by combining a liquid polyol ester with a water-insoluble, aliphatic alcohol-soluble polysaccharide polymer, but it was insufficient in terms of the effect of reducing secondary adhesion and the ease of spreading when applied. Furthermore, the cosmetic composition described in that document imparts gloss by gradually releasing its ester when applied to the skin, and the mechanism of gloss imparting is different from that of the present invention.

[0005] Therefore, the object of the present invention is to provide an oily composition that exhibits excellent ease of application, clear contours after application, maintenance of gloss of the cosmetic film, and a secondary adhesion-free effect.

[0006] In light of the above circumstances, the inventors focused on the fact that ethylcellulose and a specific oil form an oily gel rich in flexibility and elasticity, and conducted diligent research. As a result, they found that in an oily composition combining ethylcellulose, organically modified clay mineral, and phenyl-modified silicone, ethylcellulose and phenyl-modified silicone form a gel with excellent transparency and elasticity in the oily formulation, resulting in a highly glossy cosmetic film with excellent gloss retention over time and reduced secondary adhesion. Furthermore, they found that by incorporating organically modified clay mineral, the clarity of the contour after application and the ease of spreading during application are excellent, thus completing the present invention.

[0007] In other words, the present invention includes the following inventions: [1] The present invention relates to an oily composition containing 1 to 40% by mass of the following components (A) to (C): (A) ethyl cellulose (B) organically modified clay mineral (C) phenyl-modified silicone.

Its weight-average molecular weight is preferably in the range of 1,000 to 30,000, and more preferably in the range of 3,000 to 15,000 from the viewpoint of performance and workability such as filtration.

[0046] In the organohydrogenpolysiloxane represented by the above formula (4) having two or more hydrosilyl groups in one molecule, R ４ These are monovalent hydrocarbon groups that do not have a hydrogen atom or an aliphatic unsaturated bond with 1 to 30 carbon atoms, and all R ４ Two or more of the atoms inside are hydrogen atoms.

[0047] In the above formula (4), e, f, g, and h should be 0 or positive numbers and selected to satisfy 2 ≤ e + f + g + h < 32. Preferably, g = 0 and h = 0, more preferably e = 2, 0 ≤ f < 30, g = 0, h = 0, and even more preferably e = 2, 0 ≤ f ≤ 20, g = 0, h = 0. If the number of silicon atoms contained in component (Y) is 32 or more, the crosslinked organosilicon resin tends to become gel-like as it holds onto the solvent. Therefore, it tends to form a sticky film after the solvent evaporates. If the number of silicon atoms contained in component (Y) is less than 32, the crosslinked organosilicon resin tends to become liquid-like as it dissolves in the solvent. Therefore, it is easier to obtain a film that is not sticky after the solvent evaporates.

[0048] The above R ３ These are, independently of each other, organopolysiloxane-containing groups, or the R ２ The group is selected from among the following. Examples of organopolysiloxane-containing groups include those represented by the following general formulas (5) to (8). ３ ３ SiO １／２ One or more R in each unit ３ R is an organopolysiloxane-containing group. ３ Some of these may be hydroxyl groups.

[0049] [In the formula, R２ The above is the same, where n and i are integers satisfying 0 ≤ n ≤ 5 and 0 ≤ i ≤ 500, and j1 to j3 are integers between 0 and 2 (inclusive).

[0050] m is an integer between 0 and 5, preferably 0 and 2. i is an integer between 0 and 500, preferably 1 and 100, and more preferably 1 and 50. If i is greater than 500, the melting point of the resin will be lower, resulting in poor film formation. j1 to j3 are integers between 0 and 2, inclusive.

[0051] In the above formula (3), b = 0 and c = 0 is preferred. When b and c are 0, the alkenyl group-containing organosilicon resin does not contain flexible skeletons such as D units or T units, and is composed only of M units and Q units. By using an alkenyl group-containing organosilicon resin that does not contain D units or T units as a raw material, the cross-linked organosilicon resin, which is the addition reaction product, can form a strong film.

[0052] In the above formula (4), g = 0 and h = 0 is preferred. When g and h are 0, the organohydrogenpolysiloxane does not contain branching components such as T units and Q units, and becomes a linear molecule composed only of M units and D units. By using a linear organohydrogenpolysiloxane as a raw material, the cross-linked organosilicon resin, which is the addition reaction product, can form a flexible film.

[0053] Furthermore, the material may contain two or more groups represented by formula (4). As the chain length of the group represented by formula (4) increases, it has the effect of imparting flexibility to the organosilicon resin. Therefore, the properties of the film can be controlled, for example, by including two types of groups represented by formula (4) with different chain lengths.

[0054] The weight-average molecular weight of the cross-linked organosilicon resin is preferably 5,000 to 1,000,000, more preferably 8,000 to 500,000, and even more preferably 10,000 to 500,000. Being within this range is more preferable in terms of performance and workability such as filtration.

[0055] In equation (3) above, a1 satisfies 0 < a1 ≤ 3, and f in equation (4) satisfies 0 ≤ f < 20, R ４A cross-linked organosilicon resin in which two of the atoms are hydrogen atoms is solid at 25°C, and a cross-linked organosilicon resin with particularly excellent film-forming properties can be obtained. The resulting film exhibits particularly excellent flexibility and oil resistance.

[0056] The constituent units of silene in the compound represented by the above average formula (2) are not particularly limited, and include at least one selected from the group consisting of M units (n=3), D units (n=2), T units (n=1), and Q units (n=0). For example, examples include a silicone resin having M units (n=3), T units (n=1), and Q units (n=0); a silicone resin having M units (n=3), Q units (n=0), and D units (n=2); a silicone resin containing all of M units (n=3), D units (n=2), T units (n=1), and Q units (n=0); a silicone resin having M units (n=3) and Q units (n=0), and so on. Among these, silicone resins containing M units (n=3), T units (n=1), and Q units (n=0), and silicone resins containing M units (n=3), D units (n=2), and Q units (n=0) are preferred, and silicone resins containing D units (n=2) are more preferred in terms of flexibility and secondary adhesion reduction effect.

[0057] The content of component (F) used in the present invention is not particularly limited, but as a lower limit, it is preferably 0.1% or more, more preferably 0.3% or more, and even more preferably 0.5% or more, as a resin purity relative to the total amount of the oily composition. As an upper limit, it is preferably 10% or less, and more preferably 5% or less, as a resin purity. As a range, it is preferably 0.1 to 10%, more preferably 0.3 to 10%, and even more preferably 0.3 to 5%, as a resin purity. This range is more preferable from the viewpoint of good color retention and secondary adhesion reduction effect.

These can be graft copolymers with organopolysiloxane groups as the main chain and hydrophilic groups as side chains, or linear block copolymers or crosslinked polymers in which organopolysiloxane groups and hydrophilic groups are alternately bonded. The organopolysiloxane groups may be linear or have a branched structure, and may be comodified with organic groups such as alkyl groups or fluorine-substituted alkyl groups.
