Abstract

PURPOSE:The titled cosmetic having a suppressed dusting tendency with the passage of time, prepared by incorporating a fatty acid ester of sucrose or maltose into a pencil-shaped cosmetic containing Japanese wax. CONSTITUTION:A pencil-shaped cosmetic obtained by incorporating 1-10wt%, based on the total amount of the cosmetic, ester of 14-22C straight chain saturated fatty acid (example; myristic acid or stearic acid) with sucrose or maltose at 1:(0.1-10) weight of the ester to Japan wax in a pencil-shaped cosmetic containing an oil component, having an IOB (inorganic Organic Balance) value of 0.08-0.50 and a liquid state at ordinary temperature and the Japanese wax. As for the above-mentioned oil component, glyceryl di-2-heptylundecanoate, trimethylolpropane triisooctanoate, castor oil, lanolin esters, etc. are mentioned and used in an amount of 5-30wt% range based on the total amount of the cosmetic.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a pencil-like cosmetic product containing wood wax-containing fatty acid ester or maltose, which suppresses powdering over time. Regarding fees.

[Prior art] Generally, eyeliner pencils, eyebrow pencils,
Pencil-shaped cosmetics such as lip pencils are manufactured by extrusion molding. Therefore, the solid oil used as a solidifying agent is required to have excellent properties such as extrusion moldability and bending strength of the molded core. From this point of view, it is essential to include wood wax as a solid oil component in pencil-like cosmetics.

[Problems to be Solved by the Invention] However, the pencil-like cosmetic No. 1 containing wood wax has a phenomenon of blooming over time, which often causes a problem of poor appearance.

As a result of intensive research aimed at suppressing powdering of pencil-like cosmetics containing wood wax over time, the present inventors found that fatty acid esters of sucrose or maltose inhibit the crystal growth of wood wax. They discovered that powder generation can be prevented, and the present invention was completed.

[Means for Solving the Problems] That is, the present invention is characterized by containing oil, wood wax, and fatty acid ester of sucrose or maltose that are liquid at room temperature and have an IOB value of 0.08 to 0.50. It is a pencil-like cosmetic product.

Hereinafter, the configuration of the present invention will be explained in detail.

The fatty acid ester of sucrose or maltose used in the present invention is an ester of sucrose or maltose and a straight saturated fatty acid having 14 to 22 carbon atoms, and is oil-soluble. Specific examples of the above fatty acids include myristic acid, palmitic acid,
These include stearic acid, alaxic acid, and hehenic acid. The amount of sucrose or maltose fatty acid ester blended is 1 to 10% by weight (hereinafter simply referred to as %) of the total amount of the pencil cosmetic, and the weight ratio of wood wax to sucrose or maltose fatty acid ester is 1:O. , 1 to 10. If the ratio to wood wax is less than 0.1, the present invention will not be effective, and if it exceeds 10, it will adversely affect usability such as spreadability.

In the present invention, the pencil-shaped cosmetic in which the fatty acid ester of sucrose or maltose, which is the essential component, is blended is a pencil-shaped cosmetic containing wood wax, as described above.
The core-bottom molding method usually uses extrusion molding, and in some cases, casting molding.

The amount of wood wax is generally 1 to 15%.

Specific examples of oils with an IOB value of 0.08 to 0.50 used in the present invention include glycerol tri-2-ethylhexylate, glycerol di-2-heptyl undecanoate, palmitin-capped isostearyl, octyldodecyl myristate,
2 octyldodecanol, 1 diisostearyl malate
, 2-decyltetradecanol, 2-ethylhexyl sebacate, diisopropyl sehakenite, diisooctyl succinate, cetyl 2-ethylhexanoate, trimethylolpropane triisooctanoate, trimethylolpropane, triisostearate, pentaerythritol tetraisooctano ate, orinib oil, castor oil, camellia oil, macadamia nut oil, lanolin ester, and the like. The blending amount is 5-30% of the total amount of pencil cosmetics.
It is.

After being left in a constant temperature bath at 5°C and 45°C for one month, the state of powder generation was observed. The results are shown in Table 1. (a), which does not contain sucrose stearate, causes intense powdering at 0°C, 15°C, and 25°C, whereas (b) to (e), which contain sucrose stearate, no longer forms powder. In particular, in the case of (d) and (e) in which the blending amount was 5% or more, no powder was formed at all even after 3 months or more under any temperature conditions.

[Effects of the invention] Pencil-shaped cosmetics generally include the pencil type, in which a core manufactured by extrusion molding is placed in a water ring or resin barrel, and the cartridge type, in which the core is poured. It is often manufactured by molding. The present invention has the effect of suppressing powder formation in pencil-shaped cosmetics over time, and this is equally effective for both the extrusion-molded core and the cast-molded core. It goes without saying that a formulation containing wood wax is also effective for cosmetics that are not particularly pencil-shaped.
