Abstract

PURPOSE:To provide a makeup cosmetic containing a volatile oil, a film-forming powdery base and a plasticizer as essential components, giving durable makeup, resistant to the migration of color, giving excellent feeling to the skin and having high safety. CONSTITUTION:A makeup cosmetic giving excellent feeling and durable makeup to the skin, resistant to the migration of color, having high safety and storable stably for along period can be produced by using a dimethylpolysiloxane (having a viscosity of 1.5cst) in combination with a cyclic polydimethylsiloxane (pentamer and/or hexamer) as volatile oil and compounding the oil with 1pt. of a powdery base, 0.1-1.0pt. of a film-forming agent and 0.1-0.9pt. of a plasticizer.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a new make-up cosmetic, which aims to be hard to remove, color transfer-free, comfortable to use, and safe. It provides high quality makeup cosmetics.

[Conventional technology]

Conventional make-up cosmetics tend to fall off over time due to sebum and sweat secretion, or may fall off due to physical effects on areas that are constantly exercised, such as the eyelids, or may fall off due to contact with objects. This has disadvantages, such as color transfer (hereinafter referred to as color transfer), which requires a lot of effort to redo makeup, and stains clothes and objects.

Therefore, in order to solve the above-mentioned drawbacks, makeup cosmetics have been developed that can add volatile oils to the cosmetic composition and form a strong coating film by volatilization of the volatile oils after application. or has been commercialized.

[Problem that the invention seeks to solve]

However, although these have sufficient functionality in terms of being difficult to remove, they have the disadvantage of being inferior in safety because they contain volatile oil. Furthermore, since these volatile oils have high volatility, there are problems in use, such as the need to pay close attention to the airtightness of the container and poor spreadability during application.

On the other hand, if a low-volatility oil is used, the compatibility with other raw materials will be poor, resulting in a decrease in product stability, and the drying time after application will be longer, making discoloration more likely.

[Means for solving problems]

Therefore, as a result of intensive research in view of the above circumstances, the present inventors have found that dimethylpolysiloxane (viscosity 1.5 cs) and cyclic polydimethylsiloxane (pentamer and/or hexamer) are used in combination as volatile oil agents. It has been found that by doing so, the above-mentioned drawbacks can be greatly improved compared to when each is used alone, and the present invention has been completed.

In order to confirm the safety of the products of the present invention, a rabbit skin irritation test was conducted on these volatile oils and other volatile oils commonly used in cosmetics. The exam is Dra
According to the ize method. The results are shown in Table 1.

Table 1. Rabbit skin secondary irritation test (values in the table indicate irritation values) *Volatile oil used in the present invention Other components constituting the present invention include a film forming agent, a powder base, and a plasticizer. The film forming agent used in the present invention is
One or more of ceresin, osikelite, microcrystalline wax, solid paraffin, beeswax, carnauba wax, candelilla wax, hydrogenated oil, higher fatty acid ester of epoxy resin, polyethylene, dimethyltrimethylpolysiloxane, monomethylpolysiloxane, abietic acid glycerin ester A desirable combination.

Powder bases used in the present invention include those commonly used in cosmetics, such as talc, mica, kaolin, sericite, titanium oxide, iron oxide, organic pigments, turmeric, and chinensis.

Plasticizers used in the present invention include liquid or paste oils commonly used in cosmetics, such as squalane, castor oil, liquid paraffin, cetyl 2-ethylhexanoate, glycerin tri-2-ethylhexanoate, and octyl myristate. Dodecyl.

Examples include octyldodecanol, vaseline, lanolin, dipentaerythritol fatty acid ester, lanolin derivatives, and fluid polyisobutylene.

Furthermore, in addition to the above-mentioned components, water, emulsifiers, pigments, dyes, pigment dispersants, perfumes, preservatives, pearlescent agents, and Jlif can be appropriately added to the makeup cosmetics of the present invention. In order to formulate the makeup cosmetics of the present invention that are non-sticky, non-color changing, comfortable to use, and highly safe, in the case of oil-based cosmetics, powder base (1 to 50 parts by weight) must be added. On the other hand,
Volatile oil (10 to 60 parts by weight), film forming agent (0.5 parts by weight)
~40 parts by weight) A plasticizer (0.5 to 40 parts by weight) is added and kneaded, and in the case of an emulsifying system, an emulsifier is also added.

Purified water, a humectant, etc. are emulsified using this kneaded product as an oil phase, and depending on the properties, the product can be filled in a tube, poured, etc.

In order to satisfy the condition of no discoloration, which is the main objective of the present invention, the blending ratio of the film forming agent, plasticizer, and powder base is important. These form a film, and the ratio is 1 to 1 part of the powder base to 0,1 to 1.0 of the film forming agent. Plasticizer is 0.1~
Most preferably, the ratio is 0.9.

When the ratio of plasticizer increases, the strength of the film becomes weaker, making it easier to discolor due to physical effects, and when the ratio of plasticizer becomes smaller, it tends to feel uncomfortable on the skin and become difficult to spread. Hail!

The ratio of film-forming agents shows the opposite trend.

Therefore, it is necessary to pay sufficient attention to these compounding ratios.
