Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a makeup cosmetic.

[0002]

2. Description of the Related Art A water-in-oil emulsified form is an emulsified form used in medicines, foods and cosmetics, and has good durability.
It is known as a composition that forms a film that can be maintained on the skin for an extended period of time. This emulsified form has been around for a long time, and various dosage forms have been developed utilizing the good persistence of the composition on the skin. The major issues in recent years have been to improve the spread and the refreshing feel, but this issue has been solved to a large extent by the emergence of volatile oils and the advancement of high internal phase technology. However, when this major problem is solved, the drawback that water-in-oil emulsions are difficult to remove by washing or the like when attached to clothes or the like due to their good durability has been highlighted. In particular, this problem is an important issue in makeup cosmetics. That is, there has been a demand for a method of suppressing the adhesion of a water-in-oil emulsified cosmetic, in particular, a makeup cosmetic to clothes. This is required at least to a lesser extent for oil-in-water emulsion cosmetics.

[0003] On the other hand, it is known that methacryl-modified polysiloxane is incorporated into a make-up cosmetic and has an action of improving the cosmetic durability by incorporating the methacryl-modified polysiloxane.
It has not been known at all that the transfer of the cosmetic is suppressed and the adhesion to clothing can be prevented by containing a specific amount of 10 to 10% by weight. It was also not known at all that this effect was more pronounced in a water-in-oil emulsion form.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made under such circumstances, and a method of suppressing the adhesion of emulsified cosmetics, particularly, makeup cosmetics to clothes, and such a method. It is an object to provide a makeup cosmetic.

[0005]

In view of such a situation, the present inventors have
Emulsified cosmetics, in particular, a method for suppressing the adhesion of make-up cosmetics to clothes and a study of such make-up cosmetics, as a result of intensive studies, revealed that they contain 5 to 10% by weight of methacryl-modified polysiloxane. In addition, they found such properties in make-up cosmetics and completed the invention. Hereinafter, the present invention will be described in detail focusing on embodiments.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION

(1) Cosmetic of the present invention The cosmetic of the present invention contains a methacryl-modified polysiloxane. This is obtained by substituting the methyl group at the terminal of methylpolysiloxane with a methacrylalkyl group as a monomer and copolymerizing it with a methacrylic acid ester or an acrylic acid ester, and many of them are already known. Among these, the most preferred in the present invention is silicone KP545 (manufactured by Shin-Etsu Chemical) diluted to 30% with decamethylcyclopentanesiloxane. The content of the methacryl-modified polysiloxane in the cosmetic of the present invention is preferably 5 to 10% by weight, more preferably 6 to 10% by weight.
-9% by weight, more preferably 7-8% by weight. This is because if the amount is too large, the feeling of use as a cosmetic may be impaired, and if the amount is too small, the effect of suppressing transfer may not be exhibited. Further, as the object of the cosmetic of the present invention, a makeup cosmetic is preferable. This is because in makeup makeup, adhesion to clothes and the like by transfer is more acute than in other makeups, and the effects of the present invention are more clearly recognized. As the dosage form of the cosmetic used in the present invention, a water-in-oil emulsion form is particularly preferred. The reason for this is that the greatest advantages of the cosmetic of the present invention, that is, the effect of suppressing transfer and the effect of preventing stains on clothes, appear extremely effectively. However, these effects of the present invention can be observed in the oil-in-water emulsified form or the oil gel form to a lesser extent. The cosmetic of the present invention may contain, in addition to the essential component, methacryl-modified polysiloxane, an optional component usually used in cosmetics. Such optional components include, for example, hydrocarbons such as petrolatum and microcrystalline wax, esters such as jojoba oil and gay wax, triglycerides such as tallow, olive oil, higher alcohols such as cetanol and oleyl alcohol, Stearic acid, fatty acids such as oleic acid, polyhydric alcohols such as glycerin and 1,3-butanediol, nonionic surfactants, anionic surfactants,
Examples include cationic surfactants, amphoteric surfactants, thickeners such as ethanol and carbopol, preservatives, ultraviolet absorbers, antioxidants, dyes, and powders. Of these, volatile oil is particularly preferably contained in the cosmetic of the present invention, and examples of the volatile oil include light isoparaffin, low molecular weight methylpolysiloxane, and cyclic methylpolysiloxane. A particularly preferred content of the volatile oil agent is 30 to 70% by weight, more preferably 35 to 6% by weight.
0% by weight, more preferably 40 to 50% by weight. It is particularly preferable to apply the cosmetic to a foundation. The cosmetic of the present invention can be produced according to a generally known method. The thus-obtained cosmetic of the present invention has an excellent transfer-suppressing action, and this action is particularly remarkable in that the transfer to clothing is suppressed. Does not stain clothes when undressed or dressed.

(2) Transfer Inhibition Method of the Present Invention As described above, by adding a methacryl-modified polysiloxane to a cosmetic, the transfer, that is, the cosmetic is applied to clothes,
It is possible to suppress the occurrence of a phenomenon in which the cosmetic adheres to the mouth of a cigarette, a tea cup, a teacup, or the like from the skin surface where the cosmetic is present and becomes dirty. That is, the method of the present invention is a method of suppressing transfer by adding 5 to 10% by weight, more preferably 6 to 9% by weight, and still more preferably 7 to 8% by weight of a methacryl-modified polysiloxane in a cosmetic. The method of the present invention is particularly preferably applied to cosmetics in the form of a water-in-oil emulsion, and is particularly preferably applied to foundations as a type of cosmetics.
