Description

  The present invention relates to a surface-treated powder obtained by subjecting (A) powder to (B) highly polymerized methylpolysiloxane and (C) methylhydrogenpolysiloxane, followed by heat treatment. The surface-treated powder relates to a cosmetic exhibiting an excellent makeup-holding effect by stably exhibiting high resistance to sweat and sebum and strong adhesion to the skin even during product formulation.

  A powder surface treatment technique in which a silicone oil such as methylhydrogenpolysiloxane is coated on the powder surface and then heated to crosslink is a technique that is widely used. This silicone surface treatment is known as a surface treatment that imparts an appropriate sliding feeling, smoothness, and water repellency to the powder. The treatment amount is 0.1 to 10 parts by mass with respect to 100 parts by mass of the powder. (See Patent Documents 1 to 3).

  There is also a known method for surface treatment of powders with organopolysiloxane having a high degree of polymerization, which has no cross-linking reaction part, and the powder is used only by its viscosity without using a chemical reaction by heating. A technique for surface treatment of the body has also been reported (Patent Document 4). Organopolysiloxane with a high degree of polymerization is highly resistant to sweat and sebum, and is a suitable material for makeup, but a silicone surface treatment film that has high viscosity but does not have chemical bonds with powders. There is a high possibility of peeling from the powder due to the manufacturing process of the cosmetic and changes over time of the cosmetic, and it does not exhibit a sufficient effect on the surface of the powder for which its function is desired.

  On the other hand, one way of thinking about the makeup holding technology for cosmetics containing powder is to increase the adhesion of powder to the skin. For example, there are technologies such as adding a highly viscous oil agent during product formulation and using a surface treatment agent with a long-chain alkyl group to improve the adhesion to the skin. On the other hand, the latter relied solely on the affinity between the skin and the powder, and was not a technique for actively attaching to the skin.

In view of the above circumstances, the present inventor can keep the highly polymerized methylpolysiloxane on the powder and give the target powder resistance to sweat and sebum and adhesion to the skin. As a result of extensive research, we have found that this problem can be solved by combining highly reactive methylpolysiloxane with no reactivity and reactive methylhydrogenpolysiloxane. It was. In other words, by utilizing the fact that methylhydrogenpolysiloxane is crosslinked by heating and further bonded to the powder surface to form a resin, the highly polymerized methylpolysiloxane is stably retained on the powder surface and its performance is fully demonstrated.

  From the results in Table 3, it was found that the surface-treated powder of the present invention stably formed a treatment film on the powder surface. The treated powders 1 to 4 relate to the surface-treated powder using the present invention, and there was little or no outflow of the treating agent even in hexane. As a result, it can be seen that the treatment film is stably present on the powder surface, and the effect is expected to be exhibited on the target powder. In contrast, the treated powder 5 is surface-treated only with highly polymerized methylpolysiloxane, and at first glance, it appears that the powder is stably treated, but the treating agent flows out by hexane. I found out. This indicates that there is a possibility that the treated film may be peeled off from the powder surface due to the manufacturing process of cosmetics and changes over time in the preparation. In other words, the target powder cannot be given resistance to sweat and sebum and high adhesion. Further, the treated powder 6 is an example in which the surface treatment is performed only with methyl hydrogen polysiloxane, but the treatment agent does not flow out by hexane, but has no function such as adhesion to the skin.

Example 1
A foundation was prepared according to the formulation shown in Table 4 below and the following production method. As the treated powder, the treated powder 1 produced in the treated powder production example 1 was used. In the following examples, the powder coated with silicone means a powder that has been coated and baked with methylhydrogenpolysiloxane (KF-9901, manufactured by Shin-Etsu Chemical Co., Ltd.).

(Usefulness evaluation results of cosmetics)

  Also in the result of Tables 5-7, it turned out that each Example of this invention has shown the higher effect compared with the comparative example. Examples 1 to 4 relate to the foundation using the treated powder of the present invention, and high evaluation was obtained for each evaluation item.
