Abstract

PURPOSE:To provide a cosmetic having excellent usability, safety and stability, by compounding an oil obtained from pili nut. CONSTITUTION:A cosmetic such as facial cosmetic, make-up cosmetic, hair cosmetic, aromatic cosmetic, body cosmetic, etc., is compounded with >=1wt% (based on whole cosmetic) oil (pili nut oil) obtained from pili nut. The obtained cosmetic exhi-bits unprecedent unique feeling. Since pili nut oil has a melting point of about 30 deg.C, the cosmetic is melted by the body heat and gives desirable spreadability especially when pili nut oil is compounded to lipstick, etc. The stability of pili nut oil can be improved by using an antioxidant such as vitamin E, BHA, BHT, anthracin, etc., in combination with pili nut oil.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cosmetic with excellent usability, which contains oil obtained from pili nuts.

[Prior Art] Pili nut is a seed obtained from Philippine Citrus orchid. The original plant is mainly Cana
rium ovatum Eng, but in addition to this, Canariu! Those obtained from lIuzonicum Gray are also treated as pili nuts.

Pili nuts are extremely high-quality fruits, but their shells are so hard that they cannot be cracked with regular nut crackers. Recently, there has been a tendency to select plants with relatively thin shells for cultivation.

Pili nuts are widely used locally as food, and their oil is also served as kerosene, but in Europe and America,
It is completely unknown in Japan, only rarely being eaten as a tabletop shell.

[Problems to be solved by the invention] As a result of the present inventors' research on pili nuts,
Surprisingly, the oil obtained from pili nuts has excellent physical properties as an oil for cosmetics, and cosmetics containing this oil are highly safe, have an unprecedented feeling of use, and have excellent stability. I found that The present invention is based on this knowledge.

[Means for Solving the Problems] That is, the present invention is a cosmetic containing oil obtained from pili nuts.

The present invention will be explained in detail below.

The oil used in the present invention is an oil obtained from pili nuts (hereinafter referred to as pili nut oil), and is usually collected from pili nuts by a method such as compression or solvent extraction.

Crude pili nut oil is a pale yellow oil containing approximately 5 oleic acids.
The main component is triglyceride with a fatty acid composition of 5% to 60%, palmitic acid 30% to 40%, and stearic acid θ to 5%. Although the color and odor are relatively good even when crude, it may be further subjected to various purification operations before being incorporated into cosmetics.

Pili nuts can be added to any type of cosmetics, such as facial cosmetics, makeup cosmetics, hair cosmetics, aromatic cosmetics, body cosmetics, etc., and provide a unique feeling of use that is not found in conventional oils. Since it has a melting point of around 30°C, it melts at body temperature, especially when blended into lipsticks, etc., giving it a pleasant and smooth feel.

Although the amount of pili nut oil to be blended is not particularly limited, it is preferably blended in an amount of 1% by weight or more based on the total amount of the cosmetic in order to take advantage of its feeling of use. There is no particular upper limit.

In addition, along with pili nut oil, vitamin E, BRAS
When an antioxidant such as BIT or andransin is used in combination, the formulation can be particularly stable.

In addition to the above-mentioned essential ingredients, the cosmetic of the present invention may contain other ingredients as necessary, within a range that does not contradict the purpose of the cosmetic of the present invention.
For example, ingredients commonly included in cosmetics such as other oils, humectants, surfactants, fragrances, colorants, preservatives, water-soluble polymers, drugs, and alcohol can be added.

[Example] Hereinafter, the present invention will be explained in detail by giving examples and comparative examples. The present invention is not limited to these. The blending amount is in weight%.

Comparative Example 1 Except for replacing pili nut oil with castor oil in Example 1,
A lipstick was obtained in the same manner as in Example 1.

The feel of the lipstick of Example 1 was compared with Comparative Example 1 to confirm its usability in an actual use test.

The test was conducted by a panel of 15 women specializing in beauty, and the results were evaluated based on the following scores.

Compared to Comparative Example 1, good...5 points Somewhat good...4 points Fair...3 points Somewhat bad...2 points Bad...1 point Table of results - Shown in 1. The numbers in the table are the number of panels that gave each rating.
