Description

Surface-treated powder and cosmetics containing the same

The present invention relates to a powder treated with a fluorine-containing copolymer (hereinafter referred to as fluorine alkyl acrylate / polyalkylene glycol acrylate polymer), more specifically, at least a part of the surface of the powder (particles) is a fluorine alkyl acrylate / polyalkylene. The present invention relates to a surface treatment (coating) powder that essentially contains a glycol acrylate polymer and a polyvalent acidic substance or a polybasic basic substance as a processing aid, and a cosmetic or the like containing the same.

Conventionally, surface treatment powders of fluorine-containing copolymers of perfluoroalkyl acrylate and polyalkylene glycol acrylate have been used as fluorine compounds to repel sebum even in systems where sweat and sebum coexist in the presence of sebum and sweat in the air. (Patent Document 1). Patent Document 2 discloses a surface-treated powder of another copolymer of perfluoroalkyl acrylate and polyalkylene glycol acrylate. These fluoropolymers are characterized in that they do not have chemically reactive groups in their molecules and are coated by physical adsorption.

On the other hand, the fluorine compound having a chemically reactive group in the molecule includes a perfluoroalkyl phosphate ester and a fluorine-containing copolymer or fluoroalkyl having excellent water and oil repellency considering the environment having a fluoroalkyl group having 6 or less carbon atoms. Silanes are disclosed (Patent Documents 3 and 4).

The weight average molecular weight of the fluoroalkyl acrylate / polyalkylene glycol acrylate polymer of the present invention is about 1,000 to 1,000,000, preferably about 5,000 to 500,000. The weight average molecular weight is a value obtained by gel permeation chromatography in terms of polystyrene.

The fluorine alkyl acrylate / polyalkylene glycol acrylate polymer may contain a crosslinkable monomer. The crosslinkable monomer can be a compound having at least two reactive groups and / or carbon-carbon double bonds and not containing fluorine. The crosslinkable monomer can be a compound having at least two carbon-carbon double bonds, or a compound having at least one carbon-carbon double bond and at least one reactive group. Examples of reactive groups are hydroxyl groups, epoxy groups, chloromethyl groups, blocked isocyanates, carboxyl groups, and the like. In the present invention, a monomer having an amino group is not used.

The crosslinkable monomer is preferably a non-fluorine crosslinkable monomer, and more preferably di (meth) acrylate.

Crosslinkable monomer is a general formula:

Wherein each X5 is a hydrogen atom or a methyl group;
R10 is an alkylene group having 2 to 10 carbon atoms in which some or all of the hydrogen atoms may be substituted with hydroxyl groups;
q is an integer of 1 to 50. ]
It is particularly preferable that the compound represented by the formula (alkylene glycol di (meth) acrylate). The carbon number of R10 is preferably 2 to 10, for example 2 to 6, particularly 2 to 4. R1 is preferably an ethylene group.

For example, when the fluorine alkyl acrylate / polyalkylene glycol acrylate polymer contains 100 parts by weight of the fluorine-containing monomer (a), the amount of the alkoxy group-containing monomer (b) is preferably 10 to 400 parts by weight, preferably May be 25 to 150 parts by weight, more preferably 43 to 100 parts by weight. This is because if it is less than 10 parts by weight, hydrophilicity cannot be obtained, and if it is more than 400 parts by weight, the oil repellency may be lowered. When the crosslinkable monomer is contained, the amount of the crosslinkable monomer is 30 parts by weight or less, for example, 0.1 to 20 parts by weight, particularly 100 parts by weight of the fluorine-containing monomer (a). The amount can be 0.5 to 10 parts by weight. This is because if it is larger than 30 parts by weight, a hard film is formed and the feeling of use may be deteriorated. The fluorine alkyl acrylate / polyalkylene glycol acrylate polymer used in the present invention can be synthesized by, for example, the method disclosed in JP-A-2000-290640, but is not limited thereto. For example, the polymerization of the fluoroalkyl acrylate / polyalkylene glycol acrylate polymer is not particularly limited, and various polymerization methods such as bulk polymerization, solution polymerization, emulsion polymerization, and radiation polymerization can be selected. For example, solution polymerization using an organic solvent or emulsion polymerization using water or an organic solvent and water in combination is generally selected.

In the surface treatment agent, the concentration of the fluoroalkyl acrylate / polyalkylene glycol acrylate polymer can be, for example, 0.01 to 50% by weight.

The coating amount (surface treatment amount) on the surface treated powder is the chemical composition of the powder to be surface treated (powder before surface treatment), its particle size, presence or absence of porous property, oil absorption, water absorption. Depending on the specific surface area, the total coating amount of the fluoroalkyl acrylate / polyalkylene glycol acrylate polymer and the polyvalent acidic substance or polyvalent basic substance as a processing aid is 100 parts by weight of the surface-treated powder. 0.01 to 40 parts by weight, preferably 0.1 to 30 parts by weight, and more preferably 0.5 to 30 parts by weight. At this time, the ratio of the processing agent to the processing aid of the fluoroalkyl acrylate / polyalkylene glycol acrylate polymer is 0.5 to 0.001 when the processing agent is 1.0 (part by weight). Preferably, it is 0.2 to 0.001. If it is less than this, a sufficient effect cannot be obtained, and if it is more than this, the function of the present polymer as a surface-treated powder will be lowered and the effect in cosmetics will be insufficient, and it will be uneconomical.

More preferably, A: B is 29.95 to 0.05 parts: 0.05 to 29.95 parts. Although it differs depending on the type of powder, the type of cosmetic, and the blending amount in the cosmetic, if these ratios are exceeded, the effect on the cosmetic tends to decrease.
