Diacylglycerin and cosmetic composition jy 5 - . = Ce
Field of industrial application wo .
The present invention relate to a liquid oil prepara- tion consisting of a new diacylglycerin. More particu- larly, it is concerned with a liquid oil preparation which is liquid at room temperature, highly stable to oxidation and decomposition, gives a good feel to the skin, and permits formulation in high concentrations.
Prior art
Acylglycerins include monoacyl-, diacyl-, and tri- , acylglycerin. Monoacylglycerin is used as a surface active agent . Triacrylglycerin is used in a broad range ‘of applications as oils and fats (represented by natural oils and fats) and also as oil preparations. By contrast, ) diacylglycerin is regarded as an impurity which has an adverse effect on the surface active performance of mono- acylglycerin and lowers the crystallinity of triacyl- glycerin.
SL. ? 2663972 ,
However, diacylglycerin per se is considered to be an oll preparation having a slight polarity owing to one hydroxyl group it possesses in its molecule. The use of diacylglycerin as a base for cosmetics and drugs is dis- closed in Japanese Patent Laid-open Nos. 44040/1979 and 166108/1981. On the other hand, there are several commer- cial diacylglycerins having a single acyl residue, such as distearoyl glycerin and dioleyl glycerin. Because of their safety, stability, and good feel, they are expected to replace the conventional oil bases such as paraffins, waxes, higher alcohols, and olive oil which are used in the cosmetic field.
Although diacylglycerin has the feature of an oil ‘preparation with polarity, it is used mainly as a crystal- line base having a high melting point. It has never attracted attention as an oil preparation for cosmetics.
It is possible to lower the melting point of diacyl- glycerin by the introduction of an unsaturated acyl group or a short-chain acyl group. However, the former deterio- rates the stability to autoxidation, and the latter makes diacylglycerin liable to decomposition and poses a problem associated with irritation and safety. Therefore, for me 3 26692 ’ diacylglycerin to pe used as a liquid oil preparation, a special device has to be made. For this reason, diacyl- glycerin has been limited in usage and application areas.
A liquid oil shields hairs to increase their water content, or acts directly on the horny layer to increase its flexibility. Unfortunately, 2a liquid oil is usually sticky and glossy with a poor feel if it produces a great shielding effect. BY contrast, a liquid oil which is not sticky and glossy is poor in flexibilizing effect and is often irritating. In order to eliminate these disadvan- tages, a liquid oil is applid to the skin and hairs in the form of an emulsified cosmetic, espeically water-in-oil type emulsion.
The diacylglycerin having the formula (1) in which the residue of a straight-chain saturated fatty acid has 14 carbon atoms and the residue of a branched-chain saturated fatty acid is shown by the formulae (i) to (iii) is disclosed in JP-A 1-106846 published on April 24. 1989: corresponding to U.S. Serial No. 246 875 filed on
Sep. 20: 1988 and EP-A 3189 126 published on June 7. 1989.
. dq
With the foregoing in mind, the present inventors studied diacylglycerin combined with a different kind of acyl group, and evaluated the performance of such diacyl- glycerin as a liquid oil preparation. As the result, it was found that diacylglycerin having the residue of a spe- cific branched-chain saturated fatty acid and the residue of a specific straight-chain saturated fatty acid in the molecule is liquid at room temperature, has good stability to oxidation and high resistance to decomposition, gives a good feel to the skin, and permits formulation in high concentrations. The present invention was completed on the basis of this finding.
The invention provides a new diacylglycerin having the formula (I):
CH,-0-R,
Si-0-R, ce. (TD)
SH-0-R, (where one each of R;, R,, and R, denotes a residue of a straight-chain saturated fatty acid having 11-17 carbon atoms, a residue of a branched-chain saturated fatty acid having 10-18 carbon atoms, and a hydrogen atom, provided that the ones are excluded in which

a. 7
The diacylglycerin of the present invention contains the residue of a straight-chain saturated fatty acid having 11-17 carbon atoms, whose examples include undeca- noic acid, dodecanoic acid, tridecanoic acid, tetra- decanoic acid, pentadecanoic acid, hexadecanoicC acid, and heptadecanoic acid. With the residue having 10 or less carbon atoms, the diacylglycerin undergoes hydrolysis so easily that it is not suitable for use as an oil prepara- tion. With the residue having 18 or more carbon atoms, the diacylglycerin has such a high freezing point that it is not suitable for use as an oil preparation.
The diacylglycerin of the present jnvention contains the residue of a branched-chain saturated fatty acid having 10-18 carbon atoms, whose examples include dimethyloctanoic acid, trimethylheptanoic acid, butyl- methylhexanoic acid, ethylmethylnonanoic acid, propyl- methylnonanoic acid, trimethyldecanoic acid, pentylmethyl- octanoic acid, putylmethylnonanoic acid, propyldodecanoic © acid, pentyldecanoic acid, hexyldecanoic acid, butyl- pentylheptanoic acid, hexyldodecanoic acid, pentyl- undecanoic acid, 7 -methyl-2- (3-methylhexyl)decanoic acid, 7-methyl-2- (3-methylbutyl)octanoic acid, and 7 7-trimethyl-2- (1,3, 3-trinethylbutyl)octanoic acid.
Additional examples which are commercially available from
Nissan Chemical Industries, Ltd. include isodecanoic acid, isotridecanoic acid, isomyristic acid, isopalmitic acid, and isostearic acid.
The diacylglycerin of the present invention may be produced from the above-mentioned branched-chain saturated fatty acid and straight-chain saturated fatty acid and glycerin by the process used for the production of ordi- nary acylglycerin. The process involves the steps of mixing the above-mentioned branched-chain saturated fatty acid and straight-chain saturated fatty acid and glycerin in equimolar amounts, heating them at 200-230°C with the elimination of water formed under reduced pressure, thereby yielding a mixture of acylglycerins, and subject- ing the mixture to distillation or column chromatography, thereby separating the fraction of diacylglycerin. The thus obtained diacylglycerin is a random mixture contain- ing a diacylglycerin composed only of the residue of a branched-chain saturated fatty acid, a diacylglycerin com- posed of the residue of a branched-chain saturated fatty acid and the residue of a straight-chain fatty acid, and a diacylglycerin composed only of the residue of a straight - chain saturated fatty acid. The desired diacylglycerin of the present invention may be obtained from the mixture by . utilizing their difference in melting point or by recrys- tallization from a proper solvent such as hexane.
There is another advantageous process, which involves the steps of converting either of the pranched-chain satu- rated fatty acid or straight-chain saturated fatty acid into a highly reactive derivative, and then esterifying the derivative.
An example of the highly reactive deriv- ative is an acid halide of a fatty acid.
A preferred example of the process which involves an acid halide is carried out as follows: One mol of a branched-chain satu- rated fatty acid (as the starting material) is reacted with 1-5 mol, preferably 1-2 mol of a halogenating agent such as thionyl chloride, thionyl bromide, and phosphorus trichloride, at 0-100°C, preferably 20-80°C, to give an acid halide.
One mol of a straight-chain saturated fatty acid is reacted with 1 mol of glycerin with heating at 200-230°C, with the elimination of water formed under reduced pressure, to give an acylglycerin of the straight- chain saturated fatty acid.
This product is subjected to molecular distillation to give a monoacylglycerin of a straight-chain saturated fatty acid. subsequently, 1 mol of the branched-chain saturated fatty acid halide is reacted with 0.5-3 mol, preferably 1-1.5 mol, of the mono- acylglycerin of a straight-chain saturated fatty acid by the aid of a dehydrohalogenating agent such as pyridine and quinoline in an amount of 1-3 mol, preferably 1-1.5 mol, for the acid halide.
This reaction is carried out in an inert solvent such as benzene, toluene, Xylene, and hexane in an amount of 1-10 times, preferably 3-5 times, the volume of the acid halide, with stirring and heating at 50-100°C, preferably 60-80°C. After the removal of amine hydrohalide formed, the acylglycerin undergoes molecular distillation or column chromatography to give the desired diacylglycerin containing the residue of a branched-chain saturated fatty acid and the residue of a straight-chain saturated fatty acid.
There is further another advantageous process for producing the desired product by using lipase without going through a highly reactive derivative. According to this process, 1 mol of a branched-chain saturated fatty acid is reacted with 1 mol of glycerin at 200-230°C, with the elimination of water formed under reduced pressure, to give an acylglycerin having the residue of the branched- chain saturated fatty acid. This acylglycerin undergoes molecular distillation to give a monoacylglycerin having the residue of the branched-chain saturated fatty acid.
This monoacylglycerin is mixed with a straight-chain satu- rated fatty acid in equimolar amount. They undergo ester- ification reaction by the aid of lipase as a catalyst to give a diacylglycerin containing the residue of a branched-chain saturated fatty acid and the residue of a straight-chain saturated fatty acid. The resulting
S11 product undergoes molecular distillation as the post- treatment according to the degree of esterification. For example, in the case where the degree of esterification of the straight-chain saturated fatty acid is low, it is nec- essary to remove the residual straight-chain fatty acid and monoacylglycerin. In addition, it is possible to remove rriacylglycerin as a by-product by molecular dis- tillation or column chromatography. This process may be carried out most effectively by using lipase having the o-position selectivity or lipase which is selective for partial glycerides. :
Among the above-mentioned processes; the lipase process is most desirable from the standpoint of economy and the purity of resulting oil preparation. No matter ' what the process, the resulting oil preparation is a mixture of monoacylglycerin, diacylglycerin, and triacyl- glycerin. To achieve the object of the present invention, it is desirable that the oil preparation contain diacrylg- lycerin in an amount higher than 85 wt%, preferably higher than 90 wt%, and that this diacylglycerin contain the one represented by the formula (I) (in which either of the two acyl groups is the residue of a straight-chain saturated fatty acid having 11-17 carbon atoms and the other is the residue of a branched-chain saturated fatty acid having 10-18 carbon atoms) in an amount higher than 90 wt%.
By the above-mentioned process, there is obtained the diacylglycerin of the present invention which has the residue of a branched-chain saturated fatty acid and the residue of a straight-chain fatty acid. It has the fol- lowing features, which make it suitable for use as a liquid oil preparation for cosmetics or external drugs to be applied directly to the skin. (1) It is liquid at room temperature. (2) It is chemically and thermally stable because the acyl group is the residue of a saturated fatty acid. (3) It gives a good feel to the skin. (4) It is highly miscible with both polar components and non-polar components, because it has a hydroxyl group in the molecule.
As mentioned above, the diacylglycerin of the present invention is liquid at room temperature and functions as a polar oil preparation which stabilizes emulsion systems.
Therefore, it is easy to handle, without the need of heating and melting the solid component which crystallizes out at room temperature. Moreover, it does not cause phase separation due to crystallization even when incorpo- rated into emulsion systems.
The diacylglycerin of the present invention may be used alone as an oil preparation of cosmetics or external drugs. lt may also be incorporated into commonly known oil preparations, vaselin, liquid paraffin, and natural fats and oils.
The invention will below be illustrated in view of the diacylglycerin having the formula (I'}.
The liquid cosmetic of the present invention has a 1ow degree of jrritation to the skin and gives a good feel with reduced stickiness and glossiness.
The component (A) applies to the above shown explanation about the diacylglycerin having the formula (1). The oil preparation of the invention may contain diacylg- lycerin in an amount higher than 70 wt%, preferably higher than 80 wt%, and more preferably higher than 90 wt% and that this diacylglycerin contain the one represented by the formula (I) {in which either of the two acyl groups is the residue of a straight-chain saturated fatty acid having 11-17 carbon atoms and the other is the residue of id a branched-chain saturated fatty acid having 10-18 carbon atoms) in an amount higher than 70 wt%, preferably higher than 80 wt%, and more, preferably higher than 90 wt%.
The lower alcohol used as component (B) in the present invention is typically ethanol or propanol.
The three components (Aa), (B), and (C) used in the present invention should be mutually soluble to give a clear product. Therefore, the amount of diacylglyerin as component (A) should be 1-40 wt%, preferably 2-20 wt%; the amount of lower alcohol as component (B} should be 45-98 wt%, preferably 55-90 wt%; and the amount of water as com- ponent (C) should be 1-50 wt$%, preferably 5-20 wt%.
If the liquid cosmetic of the present invention is to be applied to the skin, it may be incorporated with cold- feeling agents, anti-inflammatory agents, vitamins, hor- mones, and animal and vegetable extracts. For the appli- cation to hairs, it may be incorported with an anti-scurf agent and hair tonic. In either cases, it may be incorpo- rated with antioxidants, uv light absorbers, dyestuffs, perfumes, and humectants which are commonly for cosmetics.

Example 1
In a 2-liter reaction vessel equipped with a thermo- meter, nitrogen-introducing capillary, reflux condenser (with a water separating tube), and stirrer were placed 568 g (2.0 mol) of 7 -methyl-2- (3-methylhexyl)decanoic acid, 184 g (2.0 mol) of purified glycerin, and 1.2 g of calcium hydroxide.
