## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dimer diol derivative and a composition containing the dimer diol derivative, and it is an object of the present invention to provide a dimer diol derivative and a composition containing the dimer diol derivative which have an excellent water-holding property, an excellent pigment dispersion property and further a high level of safety.
2. Description of the Related Art
As materials for cosmetic, fats and oils, which are fatty acid triglyceride type, such as olive oil, palm oil, sesame oil, macadamia nut oil and mink oil or waxes such as lanolin are widely used.
Particularly, lanolin which is the ester of lanolin acid and lanolin alcohol has an excellent water-holding property and a high level of the emulsion stability and further an excellent emollient effect on the skin, it is widely used in not only emulsified products but also various makeup products and cosmetics for hairs.
However, fats and oils or waxes such as lanolin have the following problems.
Cosmetics formulated with fats and oils or waxes change over time to causes the dissociation of components and the deterioration of feeling in using when these are not adequately formulated. Further, since lanolin has a composition close to sebum and water-holding property, it has an excellent emollient effect on the skin. In recent years, however, there is a tendency of disliking animal materials from the viewpoint of the prevention of cruelty to animals. In addition, since lanolin is the ester of alcohol and fatty acid, it is of low stability and some of lanolin have decomposed and generated foul smells.
SUMMARY OF THE INVENTION
As a result of studying earnestly in consideration of the circumstances, the present inventors have found that a dimer diol derivative obtained by reacting dimer diol with epoxide has an excellent water-holding property, an excellent pigment dispersion property, and further a high level of safety and stability, thereby establishing the present invention.

(wherein a, b, c and d are each integers and are with in a range of a+b+c+d=16 to 44)
In addition, in the above chemical formula 6, R2 and R3 are alkyl groups, more specifically straight-chain alkyl groups. Examples thereof include a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a nonyl group, a decyl group, an undecyl group, a dodecyl group, a tridecyl group, a tetradecyl group, a pentadecyl group, a hexadecyl group, a heptadecyl group, an octadecyl group, a nonadecyl group, an eicosyl group and the like. R2 and R3 may be the same kind of alkyl groups as each other or may be different kind of alkyl groups.
In the above chemical formula 6, R4, and R5 are alkylene groups. Examples thereof include an ethylene group, a propylene group, a butylene group, a pentylene group, a hexylene group, a heptylene group, an octylene group, a nonylene group, a decylene group, an undecylene group, a dodecylene group, a tridecylene group, a tetradecylene group, a pentadecylene group, a hexadecylene group, a heptadecylene group, an octadecylene group, a nonadecylene group, an eicosylene group and the like. R4 and R5 may be the same kind of alkyl groups as each other or may be different kind of alkyl groups.
In the above chemical formula 6, the total number of carbon atoms of R2, R3, R4 and R5 is 14 to 42. Particularly in the present invention, the total number of carbon atoms is 18 to 40, preferably 30 to 40.
In the above chemical formula 7, a, b, c and d are each integers and satisfy the relationship: a+b+c+d=16 to 44. In the present invention, it is preferred to be a+b+c+d=18 to 40 and particularly preferred to be a+b+c+d=30 to 40.
In the above chemical formula 2, chemical formula 3, chemical formula 4 and chemical formula 5, R1 is hydrogen atoms or an aliphatic hydrocarbon group having 1 to 22 carbon atoms. The aliphatic hydrocarbon group having 1 to 22 carbon atoms may be either a straight-chain aliphatic hydrocarbon group or a branched-chain aliphatic hydrocarbon group. Examples thereof include straight-chain or branched-chain alkyl groups, alkenyl groups, alkynyl groups and the like.
More specifically, examples thereof include: straight-chain saturated aliphatic hydrocarbon groups such as a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a nonyl group, a decyl group, an undecyl group, a dodecyl group, a tridecyl group, a tetradecyl group, a pentadecyl group, a hexadecyl group, a heptadecyl group, an octadecyl group, a nonadecyl group, an eicosyl group and a behenyl group; branched-chain saturated aliphatic hydrocarbon groups such as an isopropyl group, an isobutyl group, a sec-butyl group, a tert-butyl group, an isopentyl group, a neopentyl group, an isostearyl group, an isoheptadecyl group and an isotridecyl group; straight-chain unsaturated aliphatic hydrocarbon groups such as an ethynyl group, a vynyl group, a provynyl group, a propenyl group, a geranyl, group, a linalyl group, a neryl group, an aryl group, a butenyl group, a hexenyl group, an octenyl group, a decenyl group and a hexadecenyl group; and branched-chain unsaturated aliphatic hydrocarbon groups such as an isopropenyl group and an isopropylidene group.
In the present invention, R1 is preferably a straight-chain or a branched-chain saturated aliphatic hydrocarbon group having 6 to 22 carbon atoms, more preferably a straight-chain or a branched-chain saturated aliphatic hydrocarbon group having 10 to 18 carbon atoms. The reason for this is that when R1 is a straight-chain or a branched-chain hydrocarbon group having carbon atoms being less than 6, the compatibility with other fats and oils in compositions becomes bad, and when the number of carbon atoms of R1 exceeds 22, the affinity for the skins becomes inferior; therefore, both cases are not preferred.

(wherein R6 is hydrogen atoms, the following chemical formula 9 or the following chemical formula 10, and R7 is hydrogen atoms, the following chemical formula 9 or the following chemical formula 10 (except that a case where both R6 and R7 are hydrogen atoms))




(wherein R1 is an aliphatic hydrocarbon group having 1 to 22 carbon atoms)




(wherein R1 is an aliphatic hydrocarbon group having 1 to 22 carbon atoms)
The dimer diol derivative according to the present invention has an excellent water-holding property. The dimer diol derivative according to the present invention includes a part originated from dimer diol, and a part originated from a hydrocarbon group. The part originated from dimer diol tends to take a liquid crystal structure like lipid between corneas because of a rigid structure of molecules and has a high level of water-holding property (about not less than 200%). Further, the part originated from a hydrocarbon group has a structure which is similar to fatty acid of sebum and therefore a high affinity for the skins. Thus, the dimer diol derivative according to the present invention has the excellent water-holding property, and particularly when an alkyl group having a carbon chain length close to sebum is used in the part of hydrocarbon group, the dimer diol derivative having more excellent water-holding property can be obtained.
Further, since the dimer diol derivative according to the present invention is not one where fatty acid and lanolin alcohol are bonded by ester bond to form unlike lanolin and but one where the part originated from dimer diol and the part originated from a hydrocarbon group are bonded by ether bond being chemically highly stable, substance which has a high level of hydrolysis stability and a higher level of stability can be obtained.
Next, description will be given of an example of a process suitable for producing a dimer diol derivative according to the present invention. The dimer diol derivative according to the present invention can be obtained by reacting dimer diol with epoxide.
Dimer diol is diol which is obtained by reducing dimer acid. Though the number of carbon atoms of dimer diol is not particularly limited, the dimer diol has preferably 20 to 48 carbon atoms. Particularly in the present invention, there is preferably used the dimer diol having 36 carbon atoms obtained by reducing dimer of aliphatic unsaturated carboxylic acid having 18 carbon atoms.
Examples of the commercially available dimer diol include PRIPOL 2033 manufactured by Uniqema Japan, PESPOL HP-1000 manufactured by Toagosei Co., Ltd. and the like.
It is noted that dimer diol, which is obtained by hydrogenating dimer acid obtained by dimerizing aliphatic unsaturated carboxylic acid, contains mainly compounds represented by the chemical formula 11 and the chemical formula 12.
