Problems solved by technology

However, since SLS has a protein denaturing effect, it is highly irritating to the skin
When a large amount of SLS is contained in cleansing cosmetics, there is a problem that the sebum necessary for the skin is taken away while the makeup is removed, causing skin pain
However, isononyl isononanoate is an ester commonly used as a softening agent for softening the skin, and has a problem of strong irritation to the skin.
[0007] In addition, tripropylene glycol pivalic acid was developed as an external skin preparation that is less irritating to the skin than SLS and isononyl isononanoate (see Patent Document 1), but it has a problem of poor cleansing properties

Embodiment

[0218] The present invention will be described in more detail by showing examples below, but the present invention is not limited to the following examples.

[0219] The viscosity of isostearic acid was measured at 10° C. in a strain-controlled rheometer (manufactured by Haake Co., Ltd., Leostress RS1 type) using a spinner C60 / 2Ti.

Synthetic example 1

[0220] [Synthesis Example 1: Synthesis of PDO Diisostearate]

[0221] Into a 1 L four-necked flask equipped with a stirrer, a thermometer, a nitrogen blowing tube, and a dehydrator, 79 g (1.04 mol) of 1,3-propanediol {Zemea propanediol (manufactured by DuPont Tate & Lyle BioProducts)} from microbial fermentation and 621 g of (2.13mol) isostearic acid [trade name: EMERSOL 875 (manufactured by Cognis Co., Ltd., viscosity: 103mPa·s (10°C, 10Pa))] derived from plants such as rapeseed, under a stream of nitrogen, the generated water was removed, and at the same time React at a temperature of 220° C. for 9 hours, remove excess fatty acid under reduced pressure, carry out decolorization and deodorization, and obtain 490 g of PDO diisostearate (yield 70%).

[0222] The purity of the obtained PDO diisostearate can be confirmed by gas chromatography (GC-2010 column; DB-5HT detector; manufactured by FID Corporation, Shimadzu Corporation).

[0223] The obtained PDO diisostearate is used ...

Synthetic example 2

[0224] [Synthesis example 2: Synthesis of PDO-C8 / C10 diester]

[0225] Into a 1 L four-necked flask equipped with a stirrer, a thermometer, a nitrogen blowing tube, and a dehydrator, 130 g (1.71 mol) of 1,3-propanediol {Zemea propanediol (manufactured by DuPont Tate & Lyle BioProducts)} from microbial fermentation and 407 g (2.83 mol) n-caprylic acid (caprylic acid) derived from palm kernel (manufactured by Wako Pure Chemical Industries, Ltd.) and 163 g (0.92 mol) of n-capric acid (capric acid) derived from palm kernel (manufactured by Wako Pure Chemical Industries, Ltd.), under nitrogen flow , The water generated was removed, while reacting at a temperature of 220° C. for 7 hours, the excess fatty acid was removed under reduced pressure, and decolorization and deodorization were carried out to obtain 420 g of PDO-C8 / C10 diester (yield 60%).

[0226] The purity of the obtained PDO-C8 / C10 diester can be confirmed by gas chromatography (GC-2010 column; DB-5HT detector; manufactu...

Abstract

The present invention is related to: (1) a cosmetic preparation containing an emulsifying agent, 1,3-propanediol (PDO) and a PDO difatty acid ester, wherein the fatty acid constituting the PDO difatty acid ester is composed of one or more fatty acids selected from among isostearic acid, n-octanoic acids, and n-decanoic acids; and a method for producing the cosmetic preparation; (2) a composition for cosmetic preparations, which contains the PDO difatty acid ester; a cosmetic preparation containing the composition for cosmetic preparations; and a method for producing the cosmetic preparation; and (3) a cleanser for industrial use, which contains a PDO difatty acid ester that has a fatty acid residue of an n-octanoic acid and a fatty acid residue of an n-decanoic acid. The cosmetic preparation, the composition for cosmetic preparations, and the cosmetic preparation containing the composition for cosmetic preparations have excellent cleansing properties, low irritation, moisturizing properties and feeling of use, while being reduced in the burden on the environment. The cleanser for industrial use has excellent cleansing properties and low corrosion properties, while being reduced in the burden on the environment.

Description

technical field [0001] The present invention relates to cosmetics containing dihydric alcohol and dihydric fatty acid dihydric alcohol ester and its production method, cosmetic composition containing dihydric fatty acid alcohol ester, cosmetics containing the cosmetic composition and its production method, and difatty acid alcohol containing Esters industrial cleaner. [0002] This application is based on and claims priority from Japanese Patent Application No. 2009-049899 filed in Japan on March 3, 2009, the contents of which are incorporated herein by reference. Background technique [0003] In the field of makeup in recent years, durability of makeup and good usability are required. Therefore, many cosmetics contain film-forming silicones or hydrocarbons (hereinafter sometimes referred to as "silicones"). When makeup (makeup application) is performed with such cosmetics, it is possible to suppress makeup from falling off and to provide a feeling of use suitable for the ...
