Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has excellent powder binding properties and oil binding properties after filling molding or press molding, and improves spreadability during use, feeling of use such as smoothness, and makeup retention after makeup. The present invention relates to a new makeup cosmetic product that has excellent properties, as well as good temperature resistance and impact resistance, particularly cake foundation, n.
Solid powder cosmetics and lipsticks such as cake eyeshadow and solid rouge.

The present invention aims to provide a solid oil-based cosmetic suitable for oil-based foundations, oil-based eyeliners, and the like.

Conventionally, make-up cosmetics, for example, solid powder cosmetics such as cake eye shadow, have various cosmetic powders or pigments as the main ingredients, and oil-based ingredients and surfactants are added to the powder. After treating the surface of the pigment, the pigment is compressed and solidified by means such as press molding.
In addition, solid oil-based cosmetics such as lipsticks are mainly composed of oil-based ingredients, and after pigments are dispersed therein, the method is to form a filling paste or solidify it by pouring or other means. . Even in the above-mentioned types of cosmetics, it is necessary to make them solid or viscous in order to improve usability as a product, and it is customary to use a binder. In solid powder cosmetics, substances that play the role of binders include water, alcohol, metallic soap, in addition to oil-based components such as the oils, fats, and waxes mentioned above.
Examples include water-soluble polymers, and in solid oil-based cosmetics, waxes and metal soaps in the oil-based ingredients are mainly used because they have a large effect on structure formation.
came.

However, in the former case, if the oily component is added in an amount sufficient to exert the powder binding effect, it will have the disadvantage of giving a dry or sticky feeling to the touch, and in the case of water-soluble polymers, There were problems in that the powder binding effect was weak, and water resistance and makeup retention were not good, similar to when water or alcohol was used. Furthermore, even when metal soaps are used, disadvantages have emerged, such as poor feel during use, especially poor spreadability, and a strange feeling.

Next, when mixing wax or metal soap, too much will cause problems in use, such as poor adhesion and poor spreadability, while too little will cause problems during use. It had a fatal flaw in that it weakened in terms of strength and could break or break.

In addition, mixed systems of oil, fat, wax, and metal soap have a fundamental defect in that their physical properties change easily depending on the environmental temperature, so-called weak temperature resistance. At present, no solution has been reached.

Therefore, as a result of intensive research to solve the problems faced by makeup cosmetics, the present inventor discovered that when a specific oil-soluble resin is combined with cosmetic powders, pigments, and oil-based ingredients in a certain proportion, , has excellent powder binding properties and oil binding properties, and has a good feeling of use (
The present inventors have discovered that it is possible to obtain a make-up cosmetic that has excellent spreadability, smoothness), long-lasting make-up after make-up, and good heat resistance and impact resistance, leading to the completion of the present invention.

The present invention comprises 1 to 90% by weight of an oily component, 3 to 98% by weight of a cosmetic powder and/or pigment, and 1 to 30% by weight of an oil-soluble resin.
The present invention relates to a makeup cosmetic characterized by containing % by weight.

Examples of oily components applicable to the present invention include squalane, liquid paraffin, castor oil, liquid lanolin, oleyl alcohol, lanolin alcohol, hexadecyl alcohol, inglovir myristate, octyldodecyl myristate, octyldodecyl oleate, and hexadecyl stearate. '/to, 2-functional cetyl hexanoate, 2
- Ethylhexanoic acid triglyceride, isopropyl lanophosphate, isopropyl palmitate, lanolin.

Various oils, fats, and waxes such as vaseline, hardened cottonseed oil, hard paraffin, beeswax, spermaceti, microcrystalline wax, carnauba wax, ceresinino, osichelite, candelilla wax, and silicone oil, etc., are used to improve product hardness. They may be combined as appropriate and blended in an amount of 1 to 90% by weight based on the total weight of the makeup cosmetic.

Next, as powders or pigments for cosmetics, all powders that are generally used as cosmetics can be used, such as talc, kaolin, sericite, calcium carbonate, magnesium carbonate, magnesium silicate, silicic anhydride, etc. Extender pigment, titanium dioxide.

White pigments such as zinc oxide, inorganic pigments such as red iron oxide, iron oxide, chromium oxide, gunjo, organic pigments such as tar pigments,
Examples include var pigments such as titanium mica and mica, and organic powders such as polyethylene powder and spherical nylon powder, which are added in a range of 3 to 98% by weight into makeup cosmetics.

Furthermore, 111 of the present invention (oil-soluble resins that are essential components include various petroleum resins (mp, 60 to 130°C) of aliphatic type, alicyclic type (cyclopentadiene type), and aromatic type, coumaron Or indene homopolymer scale is copolymer copolymer coumaron indene resin (mp, 130-15
0°C), and the terpene resin produced by isomerization polymerization from isoprene polymer is picolite (softening point 130-143).
°C), and hydrogenated hydrocarbon resins obtained by hydrogenating these resins (for example, Esso Escoretsu 5000, softening point 85 to 125 °C), and one or more of these may be used alone or in combination. It is added to the formulation system in combination.

These oil-soluble resins have excellent compatibility with oils and fats and can exhibit strong binding effects, but among them, alicyclic petroleum resins and hydrogenated hydrocarbon resins have a good balance of various properties. , has become the most desirable one.

Here, the amount of the oil-soluble resin blended in the makeup cosmetic is 1 to 301i. To explain in more detail, powders for cosmetics with high powder binding properties, such as Merck and inorganic pigments, have a rating of 1 to 5 when the main component is pigment.
% by weight is sufficient, and when a large amount of cosmetic powders or pigments with low powder binding properties, such as titanium mica and various varnish agents, are blended, it is necessary to It is something to do. If the amount is less than 1% by weight, powder binding effect and extraction agent binding effect cannot be expected, and if the amount exceeds 30M, the tackiness and hardness will be too poor, the amount of coating will be small, and the spreading property will be poor. The defect has become worse.
It's coming.

In addition, water-soluble bases such as glycerin, polyethylene glycol, furohylene glycol, 1,3-phthylene gelicol, etc., which are usually added to make-up cosmetics, should also be contained in an amount of 25% by weight or less. It can be used in the appropriate amount.

As described above, in the present invention, it is possible to manufacture various makeup cosmetics by selecting the various raw materials described above depending on the purpose. For example, in the case of solid powder eye color, solid powder cheek color, solid powder Noah/Dage, 1/, after mixing and pulverizing cosmetic powder and/or #lI family,
Melt oils, fats, or waxes by heating, or if they are liquid at room temperature, coat the surface of the powder or pigment, fill it into a medium plate or container, and press to obtain a solid product. Red, oily fun zone, n,
In the case of oil-based eyeliner, heat and dissolve oil, fats and waxes, mix and disperse cosmetic powder or pigment, pour into a medium plate or container, and cool. Paste-like scales produce solid products, but even in the case of collapse, oils, oils, fats, and waxes are mixed at the same time as oil-soluble resins, and the target product is 4i, so conventional However, it does not cause any trouble.

Next, in order to evaluate the makeup cosmetics obtained by the present invention, the makeup cosmetics (cake foundation, cake eye color, lipstick) of the present invention shown in Examples 1 to 3 below and the makeup cosmetics described below were tested. The oil-soluble resins in Examples 1 to 3 were replaced with conventional aluminum stearate (cake foundation) and methylpolysiloxane 11000e, respectively.
