Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to make-up cosmetics, more specifically, water-resistant,
This invention relates to a make-up cosmetic that has good sweat resistance and oil resistance, and has excellent makeup retention.

The make-up cosmetics referred to in the present invention include not only ordinary make-up cosmetics but also make-up bases used as bases thereof.

[Prior Art] Makeup cosmetics come in various forms and types, such as solid foundations made by blending powder and oil, solid eye shadow oil foundations, and lipsticks. There are also emulsion foundations that have emulsion base.
All of them are characterized by containing large amounts of inorganic powders such as talc, kaolin, iron oxide, titanium oxide, titanium/mica pearl pigments, and organic pigments such as nylon, cellulose, and tar pigments.

These make-up cosmetics tend to smear or smudge due to sebum, sweat, or oil from other cosmetics. Particularly in the hot and humid conditions of summer, makeup slippage was a common problem faced by women, and improvements were desired.

As a make-up cosmetic with good water resistance and oil resistance, a technique using ethyl hydroxyethyl cellulose as a film agent (Japanese Patent Application Laid-Open No. 1983-62994) is known, but it is still unsatisfactory in terms of make-up durability in actual use. It's not possible.

On the other hand, makeup bases are used to improve the adhesion of make-up cosmetics and give a beautiful finish, but there are few that take into account the longevity of make-up cosmetics.

[Problems to be Solved by the Invention] In view of the above circumstances, the present inventors conducted intensive research with the aim of obtaining a make-up cosmetic product that has an excellent effect of preventing makeup from fading, and as a result, developed a specific organic silicone resin. They discovered that if they were used with volatile silicone oil and powder was added to this, they could obtain a make-up cosmetic that spreads easily, has a light feel, and is effective in preventing makeup from fading. Based on this, the present invention has been completed.

[Means for Solving the Problems] That is, the present invention comprises 1 to 70% by weight of an organic silicone resin shown in (A) below, 10 to 98% by weight of a volatile silicone oil shown in (B) below, and a powder. 0.5-55
% by weight of makeup cosmetics.

(A) Average formula Rn5iOL03- (R represents a hydrocarbon group or phenyl group having 1 to 6 carbon atoms, n
represents a value from 1.0 to 1.8).

(B) At least one type of volatile silicone oil represented by general formula (I) and general formula (It).

(Hereinafter in the margin) General formula (I) General formula (I[) (In the formula, n represents an integer of 3 to 7.) (Hereinafter in the margin) The organic silicone resin represented by item (A) used in the present invention is R35iO unit, R25iO unit, RSiO±
unit and a suitable combination of 5i02 units, the proportions of which are selected to satisfy the average formula Rn SiO soil (n represents a value from 1.0 to 1.8), approximately 1500 It is desirable to have an average molecular weight of up to 10,000.

Silicone resins are soluble in Hensen and can be produced by a variety of methods. -For example, general formula R3S
jX, , R25iX2 , R51X3 and SiX4
(X represents a hydrolyzable group, such as chlorine, bromine, fluorine, alkoxy, such as methoxy, oxy, or acyloxy group), depending on the desired resin composition. - Add to a suitable solvent such as toluene, Hensen, xylene, etc. and then add this solvent to enough water to obtain the desired hydrolysis and co-condensation in a suitable acidic solvent. The aqueous phase is removed from the resulting two-phase system, the remaining resinous material is neutralized with a sufficient amount of thorium bicarbonate or other alkaline material, and the solvent is distilled off to obtain the desired organosilicone. A] 17 fats are added.

The amount of the organic silicone resin according to the present invention is 1 to 70% based on the total amount of the skin cosmetic.

In addition, the iJ ~-type silicone oil and the cyclic silicone oil represented by the general formula (1) or the general formula (IT) used in the present invention are both volatile, and the organosilicone resin is Examples include hexamethyldisiloxane, octamedyl I-lisiloxane, decamethylna-1-lasiloxane, hexademethylheptasiloxane, hexamethylcyclotrisiloxane, decamethylcyclopentasiloxane,
Te1-radecamethylcycloheptasiloxane and the like.

The blending amount is IO to 99% by weight based on the total amount of skin cosmetics.

Further, the powder used in the present invention is a powder generally used in makeup cosmetics, such as Kurji, mica,
Inorganic powders such as kaolin, calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, navy blue, chromium hydroxide, bismuth oxychloride, titanium-mica pearl pigment, and red 201 Examples include organic powders such as No. 202 Red, No. 5 Yellow Aluminum Lake, and No. 1 Blue Aluminum Lake, resin powders such as nylon, cellulose, and polyethylene, and various metal soaps.

The blending amount is 0.5 to 55% by weight based on the total amount of makeup cosmetics.

Naturally, in addition to the above essential ingredients, by combining water-based ingredients and appropriate surfactants and making full use of emulsification technology, we can emulsify water-in-oil or oil-in-water baths while maintaining the effect of preventing makeup from fading. It is also possible to make a mold makeup cosmetic.

In addition to the above, the make-up cosmetics of the present invention may also include oils and fats, waxes, drugs, fragrances, and other volatile ingredients within a quantitative and qualitative range that does not impair the effects of the present invention, depending on the purpose. etc. may be blended.

Hereinafter, the present invention will be explained in more detail with reference to Examples. The present invention is not limited by these. All compounding amounts are weight percent.
